CHAPTER 1 INTRODUCTION 1.1 PRODUCT OVERVIEW The SmartSTACK Ethernet ELS10-27TX provides a low cost, high performance solution for 10/100 Mbps switched networks. The SmartSTACK Ethernet ELS10-27TX is configured with twenty-seven RJ45 ports supporting twenty-four autonegotiating 10 Mbps ports and three autonegotiating 10/100 Mbps ports. The device also features two EPIM-100 slots that allow the user to install up to two EPIM-100s to provide multimode fiber uplinks (with potential for single mode fiber).
Introduction 1.2.1 IEEE 802.1Q Standard IEEE 802.1Q is a standard for virtual bridged local area networks (VLANs). It provides an alternate method for forwarding packets through a switch. In an 802.1D (Spanning Tree) bridge, packets are forwarded in accordance with the spanning tree as dynamically created by the 802.1D protocol (Bridge Protocol Data Units [BPDUs]), and the spanning tree state of each port. In 802.
Introduction The 802.1Q VLANs spans multiple systems and could span the entire network. Unlike Workgroups, VLANs are not limited within a particular unit. The maximum number of VLANs supported in 802.1Q mode on ELS10-27TX is 32. 1.3 802.1Q MODE ON ELS10-27TX The SmartSTACK Ethernet ELS10-27TX operates in two modes: 802.1D and 802.1Q. While operating in 802.1Q mode, ports can be configured to allow non802.1Q devices to operate in this environment. 1.3.1 VLAN Hybrid Ports (802.
Introduction 1.3.3 802.1Q Trunk Ports An 802.1Q trunk port passes all packets with the tag in place. It will not strip the tag. The port must be a hybrid port. There is no explicit command to create 802.1Q trunks ports. The following are two ways of implementing trunk ports: • Preserving Priority. The default port VLAN ID (PVID) must be identical at both ends of the trunk link. The PVID used must be a value not used anywhere else in the network to pass traffic.
Introduction 1.3.3.2 Non-Preserving Priority Use this method if there is no concern about passing priority from one device to another. Configure the same PVID at both ends of the trunk link to ensure that all traffic will be forwarded correctly.
Introduction 1.3.5 Switch Mode The unit operates in either an 802.1D or 802.1Q mode. The mode must be selected by the user and applies to all ports. The unit will not operate in a mixed mode. The default is to operate in 802.1D mode. For further information, refer to Switch Command in Chapter 2, Enhancements to LCM Commands. 1.3.6 Assigning Ports to a VLAN A port becomes a member of a VLAN, by using the VLAN command.
Introduction 1.3.8 Restricting VLANs (802.1Q Mode) This command will allow you to specify a list of VLAN IDs that should not be dynamically learned by GVRP. When the management processor receives a GVRP packet, it checks this database to determine if the learning of this ID should be restricted. NOTE There is no support for GVRP with ELS10-27TX Version 1.01.00. GVRP will be supported in a subsequent release. For usage, refer to the VLAN Command in Chapter 2, Enhancements to LCM Commands. 1.3.
Introduction 1.4 WORKGROUPS This section describes Workgroup support for the SmartSTACK Ethernet ELS10-27TX switch. The switch supports up to eight user defined Workgroups, with limited support for overlapping Workgroups. The purpose of Workgroups is to isolate broadcast and multicast traffic to within the Workgroup. In some cases, unicast traffic will also be isolated.
Introduction 1.5 DEFAULT GATEWAY A default gateway field was added to the router command to allow communication to a device on a subnet not configured on this switch. For information on configuring the Default Gateway, refer to Chapter 2, Enhancements to LCM Commands. 1.6 INSTALLATION AND MANAGEMENT For instructions on how to unpack, install, manage, troubleshoot and cable the SmartSTACK Ethernet ELS10-27TX and for a complete list of commands, refer to the SmartSTACK Ethernet ELS10-27TX User Guide.
CHAPTER 2 ENHANCEMENTS TO LCM COMMANDS 2.1 OVERVIEW The Local Console Manager (LCM) is a command-line interface built into the SmartSTACK Ethernet ELS10-27TX. The LCM enables you to monitor, manage, and configure the switch through the RS232C connection attached to any nonintelligent terminal or workstation running terminal emulation. Two modified LCM commands were added that allow setting an address limit on a port and configuring destination IP addresses for traps.
Enhancements to LCM Commands Parameters that appear in all capital letters, for example workgroups [PORT-RANGE], indicate that you must enter a value for that parameter. If a string of parameters is displayed between braces, for example [name {add|PORT-RANGE}], you must select one of the displayed options.
Enhancements to LCM Commands 2.3.2 LCM Command Syntax The following is a subset of LCM commands and syntax: switch [802.1d | 802.1Q] cut[-through] | store[-and-forward] [back[pressure] {on | off}] enable [PORT-RANGE [RIP] [TransmitPacing] [Address_Limit]] port [PORT-RANGE [speed {auto | 10[Mbps] | 100[Mbps]}] [vlan {name |VLAN-ID}] (The default VLAN ID for that port.
Enhancements to LCM Commands 2.4 BASIC LCM COMMANDS To manage the SmartSTACK Ethernet ELS10-27TX using LCM, you first must connect the switch to an ASCII terminal or terminal emulator. To use LCM, begin by pressing the Enter key several times to get the LCM prompt (ELS10-27>). 2.4.1 Help Displays the menu of available commands. Help can also be displayed by typing a question mark (?). Telnet support allows you to telnet to the device and gain access to LCM. The device allows 4 sessions.
Enhancements to LCM Commands 2.5 LCM COMMANDS The following is a list of commands that were modified for this release: • • • • • • Enable Command Route Command Port Command Switch Command Trap Control Command VLAN Command Commands are listed alphabetically in this chapter. 2.5.1 Enable Command (Address Limit) The address limit parameter was added to the enable command. If you set a limit on a port, the number of end user devices that can have connectivity will be limited.
Enhancements to LCM Commands 2.5.2 Route Command A default gateway field was added to the route command to allow communication to a device on a subnet not configured on this switch. The gateway address must be for a subnet already configured on this switch. A VLAN ID is not necessary for the gateway as it will use the VLAN ID associated with the subnet address already configured.
Enhancements to LCM Commands 2.5.3 Port Command The Port command allows you to configure the port(s) on the unit in regards to speed, duplex mode, broadcast storm protection values, GVRP, access ports, flow control, and the default VLAN ID used on each port. If the default VLAN ID for a port was configured, the port will not automatically become a member of that VLAN. Naming a VLAN. A VLAN is not named using the port command.
Enhancements to LCM Commands The following are examples of three port sub-commands on VLANs: [vlan {name |VLAN-ID}] ELS10-27>port 5-9 vlan 0x00B [GVRP {On | off}] ELS10-27>port 5-9 gvrp on [access {add | del[ete]}]] ELS10-27>port 5-9 access add 2-8
Enhancements to LCM Commands 2.5.4 Switch Command The SmartSTACK Ethernet ELS10-27TX supports two forms of Virtual LANs. One is the IEEE 802.1Q standard (spanning tree) and the other is Workgroups. The switch command allows you to select the mode in which the SmartSTACK Ethernet ELS10-27TX operates. NOTE switch Prior to changing to 802.1Q mode, all Workgroups must be deleted. When in 802.1Q mode, do not configure any workgroups. [802.1D| 802.
Enhancements to LCM Commands 2.5.5 Trap Control Command The IP address parameter was added to the trap control command. This section describes how to configure destination IP addresses for traps. Trap control gives you the ability to allow all traps or to disallow all traps. SNMP MIB variables are available to disable a particular trap, or all traps of a particular severity. The default for trap control is “disabled”.
Enhancements to LCM Commands 2.5.6 VLAN Command The VLAN command, when operating in 802.1Q mode, allows you to specify an IEEE 802.1Q VLAN. You can specify a VLAN ID, and a name to associate with that ID (optional). If you want to manage this unit on this VLAN you must also assign an IP Address either here or using the IP address command.
CHAPTER 3 CONFIGURING VLANS USING SNMP 3.1 OVERVIEW This chapter describes how to create, delete or modify VLANs on the SmartSTACK Ethernet ELS10-27TX using SNMP. This chapter describes the procedure for using the following VLAN Configuration MIBs: • The Config Table • The Config Egress List • 802.1Q Mode • The Filter GVRP table • The Static MAC table This chapter should be used in conjunction with Chapter 4, VLAN MIB Objects, in this manual. 3.
Configuring VLANs Using SNMP 3.2.1 Modifying, Creating and Deleting VLANs VLAN information that is being modified, created or deleted will remain in local variables until the status variable is set. At that time, the local variables will be processed, the Global VLAN Table will be updated and the hardware configuration modified. To Create, Delete or Modify local variables, proceed as follows: Step Action 1 Set the Config Table index to a value outside of the table range (range is 0 through 31).
Configuring VLANs Using SNMP 3.2.1.2 Creating a VLAN In addition to the checks stated in the section titled Modifying a VLAN, the following checks are also completed, if you created a VLAN: • If a restriction is in effect for any port selected for this VLAN. If one of these ports is restricted from becoming a member of this VLAN, the command is aborted. • If the IP address was specified, the IP address is set. • After passing all tests, the local variables are stored in the VLAN table.
Configuring VLANs Using SNMP - The selected ports are removed from the list of ports in the table entry. - If there are no ports left on the VLAN, and the VLAN ID does not equal 0x001, then the BPDU addresses and the MP MAC address is deleted from the address database. - All APR entries are flushed from the ARP table. - If there are no ports left on the VLAN, delete the IP address from the routing table and clear the table entry. 3.
Configuring VLANs Using SNMP 3.3.1 Modifying a Config Egress List Entry To modify a Config Egress List entry, proceed as follows: Step Action 1 Set the index outside its valid range. 2 Set the VLAN ID to the value desired. 3 Set the port variable to the value desired. 4 Set the index to the table entry you desire to modify. 5 Write any value to the status variable. When the write to the status entry is completed, an attempt will be made to carry out the command.
Configuring VLANs Using SNMP 3.4 THE FILTER GVRP TABLE The Filter GVRP Table can be used to inhibit VLANs from being learned via GVRP. It can also be used to inhibit a user from accidentally configuring a port on a VLAN they do not want. In the other tables, there are several local variables associated with the Filter GVRP Table, such as index, the VLAN ID, the list of ports, the status, and establish. In the other tables, valid entries are between 0 and 31.
Configuring VLANs Using SNMP 3.4.1.1 Creating a Filter If you created a Filter, a check is done to: • Ensure that the command is either a Create or a Delete. If it is not, the command is aborted. • Determine if the VLAN ID is valid. If not, the command is aborted. • Ensure the index is within the valid range. If it is not, the command is aborted. • If modifying an existing entry in the table, the VLAN ID that is in the table entry must match the local variable. If it does not, the command will be aborted.
Configuring VLANs Using SNMP 3.5 THE STATIC MAC ENTRY Only three local variables are accessible, the VLAN ID; the MAC address, and the port to associate with this entry. MAC addresses added via this mechanism are not saved after a reboot, and will not age. For a list of Static MAC variables, refer to Chapter 3, Configuring VLANs Using SNMP. 3.5.1 Creating a Static MAC Entry To create a new entry, proceed as follows: Step Action 1 Set the VLAN ID. 2 Set the MAC address. 3 Set the port.
CHAPTER 4 VLAN MIB OBJECTS 4.1 OVERVIEW This chapter describes the MIB objects that relate to configuring 802.1Q VLANs. The MIB system groups described alphabetically in this chapter are as follows: • Bridge Configuration • Configuration Entries • Device Entries • Egress Table • Filter GVRP • Static MAC Address Entries For procedures describing how to configure VLANs, refer to Chapter 3, Configuring VLANs Using SNMP. 4.
VLAN MIB Objects 4.2.2 Operating Mode (VlanOperatingMode) This object selects the mode of operation (802.1D = 1 or 802.1Q = 2). The switch can operate as an 802.1d switch, or as an 802.1d switch with IEEE VLAN capability (802.1Q). A read of this object will return the current operating mode. NOTE Changing the value will not change the operation of the switch until the unit is rebooted.
VLAN MIB Objects 4.2.4 GVRP Enable (VlanGVRPEnable) If the switch is operating in 802.1Q mode, it selects whether GVRP protocol messages should be processed and VLANs configured accordingly for each port on the switch. Each octet within the value of this object specifies a set of eight ports. This is a list of all ports within the VLAN.
VLAN MIB Objects 4.2.5 Access List (VlanAccessList) A list of ports that should act as ‘Access Ports’. These ports strip all tags on egress and also make use of a shared database that will automatically be kept by the firmware. Each octet within the value of this object specifies a set of eight ports. The first octet specifies ports 1 through 8. The second octet specifies ports 9 through 16, etc.
VLAN MIB Objects 4.3 CONFIGURATION ENTRIES This section provides you with VLAN configuration entries. For instructions on configuring VLANs, refer to Chapter 3, Configuring VLANs Using SNMP. 4.3.1 Entry (VlanConfigEntry) This entry allows configuration of specific VLAN entries. Although this is configured as a table, there is only a single instance. Entries must be referenced as simple variables.
VLAN MIB Objects 4.3.2 Index (VlanConfigIndex) The VLANConfigIndex is the index into the table of VLANs. The table has 32 entries (0 - 31). An index value outside this range will reference the local variable. For example, if the index is set to -1 and the els10-27VlanConfigVID object is read, the local variable (not the table entry) is read. By using an out of range value, the local variables can be read. Only the local variables are written to until an els10-27VlanConfigStatus is written.
VLAN MIB Objects 4.3.4 Ports (VlanConfigPorts) A bit mask of the ports in this VLAN. Each octet within the value of this object specifies a set of eight ports. This is a list of all ports within the VLAN.

CHAPTER 5 CONFIGURING WORKGROUPS USING LCM 5.1 OVERVIEW Workgroups are a proprietary form that was developed prior to the IEEE standard being available. Workgroups are only supported in the 802.1D mode. The ELS10-27TX supports up to eight user defined Workgroups, with limited support for overlapping Workgroups. The goal of Workgroups was to isolate broadcast and multicast traffic to within the Workgroup. In some cases unicast traffic will also be isolated.
Configuring Workgroups Using LCM 5.2 WORKGROUP CONFIGURATION EXAMPLES Figure 5-1 shows an example of a typical Workgroup configuration. In this example, two Workgroups are used: Workgroup Alpha and the Default Workgroup. Workgroup Alpha contains ports 3,5,7 and 9, and the Default Workgroup contains all ports not contained in Workgroup Alpha. NOTES 1. The system creates the Default Workgroup. 2. If Workgroups were not defined, all ports are members of the Default Workgroup. Figure 5-1.
Configuring Workgroups Using LCM It is also possible to overlap workgroups. Figure 5-2 shows how overlapping ports can communicate with ports in both Workgroups. For example, Workgroup Alpha 3-7 and Workgroup Omega 7-9. In this example, four workgroups would be created, Alpha, Omega, the default, and a superset workgroup containing all ports in Alpha and Omega. In this case ports 3-6 would be limited to communicating with ports within Alpha.
Configuring Workgroups Using LCM one of these ports, the MAC address and Workgroup pair is found in the database and sent to port 7. In our example, the packet was received on port 3 and paired with Workgroup Alpha (0x065). Conversely when packets are received on other ports (Port 3 in this example) they also will have additional entries placed into the database. In this example when a packet is received on port 3, two entries will be placed into the database for its source address.
Configuring Workgroups Using LCM ELS10-27>workgroup default add 1, 2, 10 -27 Name: default Workgroup ID: 0x001 Ports: 1, 2, 10 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27 To delete ports specify the range: ELS10-27>workgroup omega delete 8, 9 NOTE When deleting a workgroup, you must delete the entire workgroup.
CHAPTER 6 CONFIGURING WORKGROUPS USING SNMP 6.1 OVERVIEW Workgroups are a proprietary form that was developed prior to the IEEE standard being available. Workgroups are only supported in the 802.1D mode. The ELS10-27TX supports up to eight user-defined Workgroups, with limited support for overlapping Workgroups. The goal of Workgroups was to isolate broadcast and multicast traffic to within the Workgroup. In some cases unicast traffic will also be isolated.
Configuring Workgroups Using SNMP 6.2 WORKGROUP CONFIGURATION PROCEDURES You should have a familiarity with networking concepts and principles. In addition, a basic understanding of SNMP is helpful. SNMP Configuration information is shown on the following pages. To configure workgroups using SNMP, proceed as follows: Step Action 1 Read els10-27WorkGroupCurrentCount. This will tell you if another workgroup can be created. If the value is less than 8, another workgroup can be created.
Configuring Workgroups Using SNMP If ports are added to an existing workgroup, the index into the workgroup table would be written to els10-27WorkGroupNumber. This would be obtained by first reading all of the entries in the workgroup table. The name of the workgroup you want to add ports to would be written to els10-27WorkGroupName.
CHAPTER 7 WORKGROUP MIB OBJECTS 7.1 OVERVIEW You can use a Cabletron Systems Network Management System (NMS), or a standard SNMP-based Network Management System, to manage the SmartSTACK Ethernet ELS10-27TX. This section describes Workgroup configuration using the Simple Network Management Protocol (SNMP). You should have a familiarity with networking concepts and principles. In addition, a basic understanding of SNMP is helpful. SNMP Configuration information is shown on the following pages. 7.
Workgroup MIB Objects 7.2.2 Current Count (WorkGroupCurrentCount) The total number of workgroups currently defined. This will return a value between 0 and 8. els10-27WorkGroupCurrentCount OBJECT-TYPE SYNTAX INTEGER STRING (SIZE (1..8)) ACCESS read-only STATUS mandatory ::= { els10-27WorkGroup 2 } The MIB OBJECT IDENTIFIER for reading the VLANVersionNumber is: OID 1.3.6.1.4.1.97.9.14.2 7.2.3 MAX Count (WorkGroupMaxCount) The maximum number of workgroups allowed. This will always return a value of 8.
Workgroup MIB Objects 7.2.4 Table (WorkGroupTable) This table contains Workgroup definitions for the interfaces. els10-27WorkGroupTable OBJECT-TYPE SYNTAX Sequence of LxWorkGroupEntry ACCESS non-accessible STATUS mandatory ::= { els10-27WorkGroup 4 } The MIB OBJECT IDENTIFIER for reading the WorkGroupTable is: OID 1.3.6.1.4.1.97.9.14.
Workgroup MIB Objects 7.2.5 Entry (WorkGroupEntry) Each entry in this table contains a definition of a Workgroup.
Workgroup MIB Objects 7.2.5.1 Number (WorkGroupNumber) An integer that identifies the work group, used as an index to this table. When creating a new Workgroup, the value returned from the els1027WorkGroupNextNumber variable is written here. els10-27WorkGroupNumber OBJECT-TYPE SYNTAX INTEGER STRING (SIZE (1..8)) ACCESS read-write STATUS mandatory ::= { els10-27WorkGroupEntry 1 } The MIB OBJECT IDENTIFIER for reading the VLANVersionNumber is: OID 1.3.6.1.4.1.97.9.14.4.1.1 7.2.5.
Workgroup MIB Objects 7.2.5.3 Ports (WorkGroupPorts) This is a list of all ports within the Workgroup. From left to right, the first octet specifies ports 1-8, the second octet specifies ports 9-16, the third octet specifies ports 17-32 and the fourth octet specifies ports 24-27. When create or add is used, you must provide a list of ports to be included in the Workgroup. For example, if you want to include ports 1 through 4 in the Workgroup, you would use the following octet: 0XF0000000.
APPENDIX A VIRTUAL LANS (VLANS) A.1 VLANS AND FRAME TAGGING The ELS10-27TX supports IEEE 802.1Q-compliant virtual LANs (VLANs). This capability provides a highly efficient architecture for establishing VLANs within a network and for controlling broadcast/multicast traffic between workgroups. Central to this capability is an explicit frame tagging approach for carrying VLAN information between interconnected network devices.
ELS10-27TX VLAN Configuration If the ELS10-27TX is so configured, and, if the frame does not already contain a tag, a VLAN identifier is placed in a tag which is appended to frames as they are received by the switch. Within the switch and between switches compliant with IEEE 802.1Q, these identifiers are used to control the destination of all frames, preventing them from being flooded to all connected stations and interfaces.
ELS10-27TX VLAN Configuration A.2.2 PORTS IN VLAN A port is made a member of the VLAN by the VLAN command. A port can be a member of multiple VLAN IDs. If a packet is received without a tag, the default VLAN for that port is applied to the packet. The default VLAN ID for a port is set with the port command. A.2.3 VLAN EGRESS For hybrid ports, if a tag within the frame matches the PVID of the port, the tag will be stripped.
