1-2 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 dynamical...

Introduction 1-3 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 op...

Introduction 1-5 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. In order to implement this, the ports at both ends...

1-6 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,...

Introduction 1-7 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....

Introduction 1-9 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 MANAGE...

2-2 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 displ...

2-4 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 Di...

Enhancements to LCM Commands 2-7 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...

2-8 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

Enhancements to LCM Commands 2-9 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 opera...

2-10 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 ...

3-1 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.

3-4 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 flus...

Configuring VLANs Using SNMP 3-5 3.3.1 Modifying a Config Egress List Entry To modify a Config Egress List entry, proceed as follows: When the write to the status entry is completed, an attempt will be made to carry out the command. If modifying an existing entry in the table, the VLAN ID in the tab...

3-6 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 ass...

Configuring VLANs Using SNMP 3-7 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 th...

3-8 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, ref...

5-2 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 conta...

Configuring Workgroups Using LCM 5-3 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...

5-4 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 exam...

6-2 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 SNM...

Configuring Workgroups Using SNMP 6-3 If ports are added to an existing workgroup, the index into the workgroup table would be written to els10-27WorkGroupNumber.

A-1 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. Cen...

A-2 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 identi...

ELS10-27TX VLAN Configuration A-3 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.
