User’s Manual of LRP-422CST 3. SWITCH MANAGEMENT This chapter explains the methods that you can use to configure management access to the LRP Managed Switch. It describes the types of management applications and the communication and management protocols that deliver data between your management device (workstation or personal computer) and the system. It also contains information about port connection options.
User’s Manual of LRP-422CST 3.2 Management Access Overview The LRP Managed Switch gives you the flexibility to access and manage it using any or all of the following methods: An administration console Web browser interface An external SNMP-based network management application The administration console and Web browser interface support are embedded in the LRP Managed Switch software and are available for immediate use. Each of these management methods has their own advantages.
User’s Manual of LRP-422CST 3.3 Administration Console The administration console is an internal, character-oriented, and command line user interface for performing system administration such as displaying statistics or changing option settings. Using this method, you can view the administration console from a terminal, personal computer, Apple Macintosh, or workstation connected to the LRP Managed Switch's console port.
User’s Manual of LRP-422CST You can change these settings, if desired, after you log on. This management method is often preferred because you can remain connected and monitor the system during system reboots. Also, certain error messages are sent to the serial port, regardless of the interface through which the associated action was initiated. A Macintosh or PC attachment can use any terminal-emulation program for connecting to the terminal serial port.
User’s Manual of LRP-422CST 3.5 SNMP-based Network Management You can use an external SNMP-based application to configure and manage the LRP Managed Switch, such as SNMP Network Manager, HP Openview Network Node Management (NNM) or What’s Up Gold. This management method requires the SNMP agent on the switch and the SNMP Network Management Station to use the same community string. This management method, in fact, uses two community strings: the get community string and the set community string.

This allows the switch to interact with other bridging devices in your network to ensure that only one route exists between any two stations on the network, and provide backup links which automatically take over when a primary link goes down.
User’s Manual of LRP-422CST The port identifier of the transmitting port The switch sends BPDUs to communicate and construct the spanning-tree topology. All switches connected to the LAN on which the packet is transmitted will receive the BPDU. BPDUs are not directly forwarded by the switch, but the receiving switch uses the information in the frame to calculate a BPDU, and, if the topology changes, initiates a BPDU transmission.

User’s Manual of LRP-422CST 4.7.2 IGMP Snooping The Internet Group Management Protocol (IGMP) lets host and routers share information about multicast groups memberships. IGMP snooping is a switch feature that monitors the exchange of IGMP messages and copies them to the CPU for feature processing. The overall purpose of IGMP Snooping is to limit the forwarding of multicast frames to only ports that are a member of the multicast group.

User’s Manual of LRP-422CST IGMP Versions 1 and 2 Multicast groups allow members to join or leave at any time. IGMP provides the method for members and multicast routers to communicate when joining or leaving a multicast group. IGMP version 1 is defined in RFC 1112. It has a fixed packet size and no optional data.
User’s Manual of LRP-422CST The states a computer will go through to join or to leave a multicast group are shown below: Figure 4-7-6 IGMP State Transitions IGMP Querier – A router, or multicast-enabled switch, can periodically ask their hosts if they want to receive multicast traffic.

User’s Manual of LRP-422CST 4.9.1.1 Understanding IEEE 802.1X Port-based Authentication The IEEE 802.1X standard defines a client-server-based access control and authentication protocol that restricts unauthorized clients from connecting to a LAN through publicly accessible ports. The authentication server authenticates each client connected to a switch port before making available any services offered by the switch or the LAN. Until the client is authenticated, 802.
User’s Manual of LRP-422CST Authentication server—performs the actual authentication of the client. The authentication server validates the identity of the client and notifies the switch whether or not the client is authorized to access the LAN and switch services. Because the switch acts as the proxy, the authentication service is transparent to the client.
User’s Manual of LRP-422CST Figure 4-9-2 EAP Message Exchange Ports in Authorized and Unauthorized States The switch port state determines whether or not the client is granted access to the network. The port starts in the unauthorized state. While in this state, the port disallows all ingress and egress traffic except for 802.1X protocol packets. When a client is successfully authenticated, the port transitions to the authorized state, allowing all traffic for the client to flow normally.

User’s Manual of LRP-422CST 4.9.7 DHCP Snooping 4.9.7.1 DHCP Snooping Overview The addresses assigned to DHCP clients on unsecure ports can be carefully controlled using the dynamic bindings registered with DHCP Snooping. DHCP snooping allows a switch to protect a network from rogue DHCP servers or other devices which send port-related information to a DHCP server. This information can be useful in tracking an IP address back to a physical port.
User’s Manual of LRP-422CST If the global DHCP snooping is disabled, all DHCP packets are forwarded. If DHCP snooping is enabled globally, and also enabled on the VLAN where the DHCP packet is received, all DHCP packets are forwarded for a trusted port. If the received packet is a DHCP ACK message, a dynamic DHCP snooping entry is also added to the binding table.
User’s Manual of LRP-422CST The page includes the following fields: Object Description DHCP Snooping Indicates the DHCP snooping mode operation. Possible modes are: Enabled: Enable DHCP snooping mode operation. When DHCP snooping mode operation is enabled, the request DHCP messages will be forwarded to trusted ports and only allowed reply packets from trusted ports.

User’s Manual of LRP-422CST 4.9.7.4 Port Setting Configures switch ports as trusted or untrusted. Command Usage A trusted interface is an interface that is configured to receive only messages from within the network. An untrusted interface is an interface that is configured to receive messages from outside the network or firewall. When DHCP snooping is enabled both globally and on a VLAN, DHCP packet filtering will be performed on any untrusted ports within the VLAN.

User’s Manual of LRP-422CST 4.9.7.6 Database Agent Overview of the DHCP Snooping Database Agent When DHCP snooping is enabled, the switch uses the DHCP snooping binding database to store information about untrusted interfaces. The database can have up to 8192 bindings. Each database entry (binding) has an IP address, an associated MAC address, the lease time (in hexadecimal format), the interface to which the binding applies, and the VLAN to which the interface belongs.
