Chapter 7 Establishing Switch Access This chapter describes various methods for accessing the Avaya P330 CLI and logging in with the appropriate security level.
Chapter 7 Establishing Switch Access P330 Sessions You can use sessions to switch between the CLI of P330 modules, other stack entities (for example, an X330 ATM or WAN entity plugged into a specific P330 switch or with the G700 Media Gateway Processor), or to switch between Layer 2 and Layer 3 commands in the router module. To switch between P330 modules use the command: session [] . The is the number of the module in the stack, counting from the bottom up.
Chapter 7 6 7 Establishing Switch Access At the prompt, type reset and press Enter to reset the stack. After the Reset, log in again as described above. At the prompt, type set ip route and replace and with the destination and gateway IP addresses. Establishing a Telnet Connection Perform the following steps to establish a Telnet connection to the Avaya P330 for configuration of Stack or Router parameters.
Chapter 7 Establishing Switch Access 5 When you are prompted for a password, enter the User Level password root in lower case letters (do NOT use uppercase letters). The User level prompt will appear when you have established communications with the Avaya P330. Establishing a Modem (PPP) Connection with the P330 Overview Point-to-Point Protocol (PPP) provides a Layer 2 method for transporting multi-protocol datagrams over modem links.
Chapter 7 Establishing Switch Access Security Levels There are four security access levels – User, Privileged, Configure, and Supervisor. • The User level (‘read-only’) is a general access level used to show system parameter values. • The Privileged level (‘read-write’) is used by site personnel to access stack configuration options. • The Configure level is used by site personnel for Layer 3 configuration.
Chapter 7 Establishing Switch Access Defining new local users Define new users and access levels using the following command in Supervisor Level: In order to... Use the following command... Add a local user account and configure a user (name, password and access level) username To remove a local user account no username Display the username, password and access type for all users on the switch show username Exiting the Supervisor Level To exit the Supervisor level, type the command exit.
Chapter 8 User Authentication Introduction A secure system provides safeguards to insure that only authorized personnel can perform configuration procedures. In Avaya P330, these safeguards form part of the CLI architecture and control remote access via SNMP, Telnet, and SSH. In addition, you can block any of the IP protocols supported by the P330.
Chapter 8 User Authentication control the P330. Manager/Agent Communication There are several ways that the SNMP manager and the agent communicate. The manager can: • Retrieve a value – a get action The SNMP manager requests information from the agent, such as the link status of an Ethernet port or the number of good packets received on the switch. The agent gets the value of the requested MIB variable and sends the value back to the manager.
Chapter 8 User Authentication ’WriteCommG’ group by default. This allows you to view the agent’s MIB tree and change any of the values in the MIB tree. L If you delete the ReadCommN or WriteCommN users, the ReadCommG or WriteCommG groups, or the SNMPv1View you may not be able to access the switch using SNMPv1 or SNMPv2c. In addition, traps are sent to designated trap receivers. Packets with trap information also contains a trap community string. SNMPv2c SNMPv2c is very similar to SNMPv1.
Chapter 8 User Authentication • • AuthNoPriv – User authentication is performed based on MD5 or SHA algorithms. The message is sent with an HMAC that is calculated with the user key. The data part is sent unencrypted. AuthPriv – User authentication is performed based on MD5 or SHA algorithms. The message is sent in encrypted MAC that is calculated with the user key, and the data part is sent with DES56 encryption using the user key.
Chapter 8 • • • • • User Authentication SNMPv1 – The name of the view for anyone communicating with the device via SNMPv1. SNMPv2c – The name of the view for anyone communicating with the device via SNMPv2c. NoAuthNoPriv – The name of the view for SNMPv3 NoAuthNoPriv users. AuthNoPriv – The name of the view for SNMPv3 AuthNoPriv users. AuthPriv – The name of the view for SNMPv3 AuthPriv users.

Chapter 8 User Authentication SSH Protocol Support Introduction to SSH SSH (Secure Shell) protocol is a security protocol that enables establishing a remote session over a secured tunnel, also called a remote shell. SSH accomplishes this by creating a transparent encrypted channel between the local and remote devices. In addition to remote shell, SSH also provides secure file transfer between the local and remote devices. SSH uses password authentication.

In order to... Use the following command...
Chapter 8 User Authentication SCP Protocol Support In addition to data transfer via an SSH session, the SSH protocol is also used to support SCP for secure file transfer. When using SCP, the P330 is the client, and an SCP server must be installed on the management station. After defining users on the SCP server, the device acts as an SCP client. The procedure described in the “Introduction to SSH“ on page 46 is used with the roles of the P330 and the client computer reversed.
Chapter 8 User Authentication RADIUS Introduction to RADIUS User accounts are typically maintained locally on the switch. Therefore, if a site contains multiple Avaya Switches, it is necessary to configure each switch with its own user accounts. Additionally, if for example a 'read-write' user has to be changed into a 'read-only' user, you must change all the 'read-write' passwords configured locally in every switch, in order to prevent him from accessing this level.
Chapter 8 User Authentication Figure 8.2 illustrates the RADIUS authentication procedure: Figure 8.
Chapter 8 User Authentication Radius Commands The following RADIUS commands are accessible from Supervisor level. In order to... Use the following command... Enable or disable authentication for the P330 switch.
Chapter 8 User Authentication Telnet Client Support Introduction to Telnet The P330ML supports invocation of a Telnet client from the CLI. The Telnet client implementation enables you to control the destination port for connecting daemons that listen on a non-default port. Authentication when connecting to the switch via Telnet is identical to standard console connection authentication (local or RADIUS).
Chapter 8 User Authentication Recovery Password Introduction The P330 provides a recovery password in the event that you have forgotten the login password for the switch. The recovery password feature enables you to login to the device in a super user mode and change the regular login password. The recovery password feature can be disabled preventing unauthorized user to login to the device using the recovery password.
Chapter 8 User Authentication Allowed Managers Allowed Managers Introduction With the Allowed Managers feature, the network manager can determine who may or may not gain management access to the switch. The feature can be enabled or disabled (default is disabled). When enabled, only those users that are configured in the Allowed Managers table are able to gain Telnet, HTTP, and SNMP management access to the switch.
Chapter 8 User Authentication Allowed Protocols Allowed Protocols Introduction With the Allowed Protocols feature, the network manager can determine the IP protocols enabled on the switch. This feature can be used to block access to the switch using specific IP protocols. Each protocol can be independently enabled or disabled on the switch. L Enabling and disabling the Recovery Password protocol can only be done using a direct console connection via the Console port.

Chapter 11 Avaya P330 Layer 2 Features This section describes the Avaya P330 Layer 2 features. It provides the basic procedures for configuring the P330 for Layer 2 operation. Overview The P330 family supports a range of Layer 2 features. Each feature has CLI commands associated with it. These commands are used to configure, operate, or monitor switch activity for each of the Layer 2 features. This section of the User’s Guide explains each of the features.
Chapter 11 Avaya P330 Layer 2 Features Ethernet Ethernet is one of the most widely implemented LAN standards. It uses the Carrier Sense Multiple Access with Collision Detection (CSMA/CD) access method to handle simultaneous demands. CSMA/CD is a multi-user network allocation procedure in which every station can receive the transmissions of every other station. Each station waits for the network to be idle before transmitting and each station can detect collisions by other stations.
Chapter 11 Avaya P330 Layer 2 Features Speed The IEEE defines three standard speeds for Ethernet: 10, 100 and 1000 Mbps (also known as Ethernet, Fast Ethernet and Gigabit Ethernet respectively). Flow Control The process of adjusting the flow of data from one device to another to ensure that the receiving device can handle all of the incoming data. This is particularly important where the sending device is capable of sending data much faster than the receiving device can receive it.
Chapter 11 Avaya P330 Layer 2 Features This classification is based either on the packet’s original priority tag, or, if the packet arrives at the port untagged, based on the priority configured for the ingress port (using the set port level CLI command). In cases where the packet was received tagged, this priority tag is retained when the packet is transmitted through a tagging port.

Chapter 11 Avaya P330 Layer 2 Features VLAN Configuration VLAN Overview A VLAN is made up of a group of devices on one or more LANs that are configured so that they operate as if they form an independent LAN, when in fact they may be located on a number of different LAN segments. VLANs can be used to group together departments and other logical groups, thereby reducing network traffic flow and increasing security within the VLAN.
Chapter 11 Avaya P330 Layer 2 Features In Figure 11.2, the switch has three separate VLANs: Sales, Engineering, and Marketing (Mktg). Each VLAN has several physical ports assigned to it with PC’s connected to those ports. When traffic flows from a PC on the Sales VLAN for example, that traffic is only forwarded out the other ports assigned to that VLAN. Thus, the Engineering and Mktg VLANs are not burdened with processing that traffic. Figure 11.
Chapter 11 Avaya P330 Layer 2 Features privacy, but the whole building has a shared high-speed connection to the ISP. In order to accomplish this, P330 allows you to set multiple VLANs per port. The three available Port Multi-VLAN binding modes are: • Bind to All - the port is programmed to support the entire 3K VLANs range. Traffic from any VLAN is forwarded through a port defined as “Bind to All”.
Chapter 11 Avaya P330 Layer 2 Features Automatic VLAN Learning The Avaya P330-ML learns the VLANs automatically from traffic received on ports in “bind-to-all” mode. The maximum number of VLANs, 252, includes these dynamically learned VLANs and any VLANs you added manually. When the VLAN list for the switch is full, no further dynamic learning or manual VLAN configuration will be possible until the dynamically learned VLANs are deleted from the table.

Chapter 11 Avaya P330 Layer 2 Features Port Based Network Access Control (PBNAC) Port Based Network Access Control (IEEE 802.1X) is a method for performing authentication to obtain access to IEEE 802 LANs. The protocol defines an interaction between 3 entities: • Supplicant — an entity at one end of a point-to-point LAN segment that is being authenticated by an authenticator attached to the other end of that link.
Chapter 11 Avaya P330 Layer 2 Features will be blocked. When PBNAC is activated, the application immediately places all ports in a blocking state unless they were declared “Force Authenticate”. They will be reverted to “Forwarding” state only when the port is authorized by the RADIUS server. L The actual state of ports configured as “Force Authenticate” is determined by the STA. • Configuring the P330 for PBNAC This section lists the basic tasks required to configure a P330 stack for PBNAC.

Chapter 11 Avaya P330 Layer 2 Features Spanning Tree Protocol Overview Avaya P330 devices support both common Spanning Tree protocol (802.1d) and the enhanced Rapid Spanning Tree protocol (802.1w). The 802.1w is a faster and more sophisticated version of the 802.1d (STP) standard. Spanning Tree makes it possible to recover connectivity after an outage within a minute or so. RSTP, with its “rapid” algorithm, can restore connectivity to a network where a backbone link has failed in much less time.
Chapter 11 Avaya P330 Layer 2 Features Rapid Spanning Tree Protocol (RSTP) About the 802.1w Standard The enhanced feature set of the 802.1w standard includes: • Bridge Protocol Data Unit (BPDU) type 2 • New port roles: Alternate port, Backup port • Direct handshaking between adjacent bridges regarding a desired topology change (TC). This eliminates the need to wait for the timer to expire. • Improvement in the time it takes to propagate TC information.
Chapter 11 Avaya P330 Layer 2 Features • Point-to-point Link ports — This port type applies only to ports interconnecting RSTP compliant switches and is used to define whether the devices are interconnected using shared Ethernet segment or point-to-point Ethernet link. RSTP convergence is faster when switches are connected using point-to-point links. The default setting for all ports – automatic detection of point-to-point link – is sufficient for most networks.

Configuring the P330 for MAC Aging This section describes the configuration of the P330 for the MAC Aging functionality. • MAC Aging is configured on the stack level. • MAC Aging can be globally enabled/disabled using the set mac-aging command. — After firmware upgrade to version 4.0, MAC Aging default state is disabled.
Chapter 11 Avaya P330 Layer 2 Features LAG LAG Overview A LAG uses multiple ports to create a high bandwidth connection with another device. For example: Assigning four 100BASE-T ports to a LAG on an Avaya P330 allows the switch to communicate at an effective rate of 400 Mbps with another switch. LAGs provide a cost-effective method for creating a high bandwidth connection. LAGs also provide built-in redundancy for the ports that belong to a LAG.
Chapter 11 Avaya P330 Layer 2 Features LAG Implementation in the Avaya P330 Family of Products This section describes the implementation of the LAG feature in the P330 Family of products. With the P334T-ML, you can aggregate the two GBIC ports to form a LAG, you can aggregate the bandwidths of 6 groups of up to 8 10/100BaseT ports in a LAG, for a maximum of 7 LAGs per switch.
Chapter 11 Avaya P330 Layer 2 Features Port Redundancy Port redundancy involves the duplication of devices, services, or connections, so that, in the event of a failure, the redundant device, service, or connection can take over for the one that failed. In addition to Link Aggregation Groups—which comprise the basic redundancy mechanism within the switch—the P330 offers an additional port redundancy scheme.
Chapter 11 Avaya P330 Layer 2 Features Intermodule Port Redundancy The intermodule port redundancy feature supports one pair of redundant ports per stack. The secondary port is activated: • when the primary port link is down, or • when the module in the stack holding the primary port has been powered down or removed. Switching time for intermodule port redundancy is approximately 1 second. L Defining intermodule port redundancy on ports with no link causes both ports to be disabled.

Chapter 11 Avaya P330 Layer 2 Features RMON RMON Overview RMON, the internationally recognized network monitoring standard, is a network management protocol that allows network information to be gathered at a single workstation. You can use RMON probes to monitor and analyze a single segment only. When you deploy a switch on the network, there are additional components in the network that cannot be monitored using RMON. These components include the switch fabric, VLAN, and statistics for all ports.

SMON extends the RMON standard to provide the switch monitoring tools and features you need to analyze the switched network and all its components. SMON provides the basis for top-down network monitoring. Top-down monitoring starts when the you notice particular traffic flow patterns in a global view of the network.
Chapter 11 Avaya P330 Layer 2 Features Port Mirroring Configuration Port Mirroring Overview Port Mirroring copies all received and transmitted packets (including local traffic) from a source port to a predefined destination port, in addition to the normal destination port of the packets. Port Mirroring, also known as “sniffing” is useful in debugging network problems. Port mirroring allows you to define a source port and a destination port, regardless of port type.
Chapter 11 Avaya P330 Layer 2 Features Multilayer Policy Multilayer Policy is a set of features for enforcing QoS and Access Control policy on routed and switched packets. One of its major goals is supporting Differentiated Services for Avaya VoIP solutions. About Multilayer Policy Multilayer Policy is enforced on the 10/100 Mbps ports of a P334T-ML module.
Chapter 11 Avaya P330 Layer 2 Features DSCP-to-COS Maps DSCP-to-COS maps set the frame 802.1p priority according to the DSCP priority value. For each DSCP value, the map contains a corresponding COS. The map changes the COS value for frames that match an active Access List rule with a “permit” action. The following conditions apply to DSCP-to-COS maps: • DSCP-to-COS maps are defined within the Policy Lists.
Chapter 11 • • • • Avaya P330 Layer 2 Features TCP/UDP port ranges can only have sizes of 2n, where the lower port of the range is aligned to the range number. — For example, for a range of 32 ports (25), the lower ports can have the value of 32, 64, 96, etc. — This limitation does not apply when the device is in “Router” policy type. Only L3 rules (based on Src/Dest IP address) will be enforced on IP fragments. Therefore, if an L4 rule is applicable to an IP fragment, the fragment will be dropped.

Chapter 11 Avaya P330 Layer 2 Features Weighted Queuing The Weighted Queuing feature allows the user to configure the priority scheme between the internal priority queues as “Strict Priority” or to configure it as a Weighted Round Robin (WRR) scheme, with user-configurable weights. L If the queuing scheme commands are to be implemented on a P330-ML switch other than the stack master, a session should be opened to the relevant switch.
Chapter 11 Avaya P330 Layer 2 Features Port Classification Overview With the P330, you can classify any port as regular or valuable. Setting a port to valuable means that, in case of Ethernet link failure of that port, a link fault trap can be sent even when the port is disabled and a fast aging operation on the CAM table will be performed.
Chapter 11 Avaya P330 Layer 2 Features Stack Redundancy In the unlikely event that a P330 switch or Octaplane link should fail, stack integrity is maintained if the redundant cable is connected to the stack. The broken link is bypassed and data transmission continues uninterrupted. The single management IP address for the stack is also preserved for uninterrupted management and monitoring.

Chapter 12 Avaya P330 Layer 3 Features Introduction This section describes the Avaya P330 Layer 3 features. It provides the basic procedures for configuring the P330 for Layer 3 operation. L Layer 3 features are relevant to P334T-ML operating in router mode. You must purchase a Layer 3 preconfigured P334T-ML module or a Routing License Key Certificate for the P334T-ML in order to operate the P334T-ML in router mode.
Chapter 12 Avaya P330 Layer 3 Features packet moves through the internetwork, its physical address changes but its protocol address remains constant. This process is illustrated in the figure below. Figure 12.1 Routing The relation between the destination host’s protocol address and its physical address is obtained by the routers using the ARP request/reply mechanism, and the information is stored within the ARP table in the router (see “The ARP Table“ on page 111).
Chapter 12 Avaya P330 Layer 3 Features Routing Configuration Forwarding The P330 forwards IP packets between IP networks. When it receives an IP packet through one of its interfaces, it forwards the packet through one of its interfaces. The P330 supports multinetting, enabling it to forward packets between IP subnets on the same VLAN as well as between different VLANs. Forwarding is performed through standard means in Router mode.

Chapter 12 Avaya P330 Layer 3 Features RIP (Routing Interchange Protocol) Configuration RIP Overview RIP is a “distance vector protocol”— that is, the router decides which path to use on distance (the number of intermediate hops). In order for this protocol to work correctly, all of the routers (and possibly the nodes) need to gather information on how to reach each destination in the Internet.
Chapter 12 Avaya P330 Layer 3 Features RIP2 RIP2 overcomes some of the shortcomings of RIP. The table below summarizes the differences between RIP and RIP2.

Chapter 12 Avaya P330 Layer 3 Features OSPF (Open Shortest Path First) Configuration OSPF Overview OSPF is a routing protocol developed for IP networks based on the shortest path first or link-state algorithm. It was introduced to overcome the limitations of RIP in increasingly complex network designs. OSPF is based on the cost of a particular path. In contrast, RIP uses hops as a path criterion. Also, updates are sent on a “need to know” basis rather than every 30 seconds as with RIP.

Chapter 12 Avaya P330 Layer 3 Features Static Routing Configuration Static Routing Overview When dynamic routing protocols (RIP or OSPF) are not appropriate, you can manually configure static routes to indicate the next hop on the path to the final packet destination. A static route becomes inactive if the interface over which it is defined is disabled. When the interface is enabled, the static route becomes active again.
Chapter 12 Avaya P330 Layer 3 Features In order to... Use the following command...
Chapter 12 Avaya P330 Layer 3 Features Route Redistribution Route redistribution is the interaction of multiple routing protocols. OSPF and RIP can be operated concurrently in the P330. In this case, the P330 can be configured to redistribute routes learned from one protocol into the domain of the other routing protocol. Similarly, static routes may be redistributed to RIP and to OSPF.
Chapter 12 Avaya P330 Layer 3 Features ARP (Address Resolution Protocol) Table Configuration ARP Overview IP logical network addresses are independent of physical addresses. Since the physical address must be used to convey data in the form of a frame from one device to another, a mechanism is required to acquire a destination device hardware address from its IP address. This mechanism/ability is called ARP (Address Resolution Protocol).
Chapter 12 Avaya P330 Layer 3 Features The ARP Table The ARP table is used to store recently used pairs of IP/MAC addresses. This saves time and communication costs, since the host looks in the ARP cache first when transmitting a packet. If the information is not there, then the host sends an ARP Request (see Figure 12.2). ARP CLI Commands 140 In order to... Use the following command...
Chapter 12 Avaya P330 Layer 3 Features BOOTP/DHCP (Dynamic Host Configuration Protocol) Relay Configuration BOOTP/DHCP Overview BOOTP Short for Bootstrap Protocol, BootP is an Internet protocol that enables a diskless workstation to discover its own IP address, the IP address of a BOOTP server on the network, and a file to be loaded into memory to boot the machine. This enables the workstation to boot without requiring a hard or floppy disk drive.
Chapter 12 Avaya P330 Layer 3 Features The DHCP/BOOTP server uses the relayed network information to decide from which subnet the address should be allocated. Therefore, the DHCP/BOOTP server must be configured to allocate addresses from the relayed networks configured on the P330. DHCP/BOOTP Relay in P330 is configurable per VLAN and allows you to specify two DHCP/BOOTP servers. In this case, it duplicates each request, and sends it to both servers.
Chapter 12 Avaya P330 Layer 3 Features NetBIOS Re-broadcast Configuration NetBIOS Overview Short for Network Basic Input Output System, an application programming interface (API) that augments the DOS BIOS by adding special functions for localarea networks (LANs). Almost all LANs for PCs are based on the NetBIOS. Some LAN manufacturers have even extended it, adding additional network capabilities. The Avaya P330 can be configured to relay netbios UDP broadcast packets.
Chapter 12 Avaya P330 Layer 3 Features VRRP (Virtual Router Redundancy Protocol) Configuration VRRP Overview VRRP is an IETF protocol designed to support redundancy of routers on the LAN, as well as load balancing of traffic. VRRP is transparent to host stations, making it an ideal choice when redundancy, load balancing and ease of configuration are all required. The concept underlying VRRP is that a router can backup other routers, in addition to performing its primary routing functions.
Chapter 12 Avaya P330 Layer 3 Features VRRP Configuration Example 1 Figure 12.3 IP: 20.20.20.10 DG: 20.20.20.1 VRRP Configuration Example (Case 1, Case 2) Backup Router 2 VRID: 2, IP: 30.30.30.2 Ass.
