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. One for Alpha (0x065) and one for the superset (0x06e).
Workgroups can be configured using either the console or SNMP. SNMP
Workgroup Configuration is described in Chapter 6, Workgroup MIB Objects.
5.3 LCM WORKGROUP COMMANDS
The workgroup command allows you to group ports together to limit the scope of
broadcast, multicast and unicast packets. If there are no user defined workgroups,
one default group exists consisting of all ports. As workgroups become defined,
ports are removed from the default group and added to the newly defined group.
The following is an example of the LCM workgroup command:
ELS10-27> workgroup [NAME [ad[d] [del[ete] | PORT_RANGE]]
To display all workgroups, enter the command:
ELS10-27>workgroup
To create/add a workgroup, enter the command:
ELS10-27>workgroup alpha add 3-7
Name: alpha
Workgroup ID: 0x065
Ports: 3, 4, 5, 6, 7,
ELS10-27>workgroup omega add 7-9
Name: omega
Workgroup ID: 0x066
Ports: 7, 8, 9,
NOTE
Workgroups are only valid in 802.1D mode.
