VLAN groups
11
The device’s memory must be configured to contain at least the number of VLANs you specify
for the higher end of the range. For example, if you specify 2048 as the VLAN ID at the high end
of the range, you first must increase the memory allocation for VLANs to 2048 or higher. Refer
to “Allocating memory for more VLANs or virtual routing interfaces” on page 319.
2. The CLI directs you to the VLAN group configuration level. Add tagged ports to the group. Since
all the VLANs in the group share the ports, you must add the ports as tagged ports.
BigIron RX(config-vlan-group-1)# tagged e 1/1 to 1/2
Syntax: [no] tagged ethernet [to <slot-number>/<port-number> | ethernet
<slot-number>/<port-number>]
3. If required, you can add and remove individual VLANs or VLAN ranges from the VLAN group
configuration level. For example, to add VLANs 1001 and 1002 to VLAN group 1 and remove
VLANs 900 through 1000, enter the following commands.
BigIron RX(config-vlan-group-1)# add-vlan 1001 to 1002
BigIron RX(config-vlan-group-1)# remove-vlan 900 to 1000
Syntax: [no] add-vlan <vlan-id> [to <vlan-id>]
Syntax: remove-vlan <vlan-id> [to <vlan-id>]
Verifying VLAN group configuration
To verify configuration of VLAN groups, display the running configuration file. If you have saved the
configuration to the startup configuration file, you also can verify the configuration by displaying the
startup configuration file. The following example shows the running configuration information for
the VLAN group configured in the previous examples. The information appears in the same way in
the startup configuration file.
BigIron RX(config)# show running-config
lines not related to the VLAN group omitted...
vlan-group 1 vlan 2 to 900
add-vlan 1001 to 1002
tagged ethe 1/1 to 1/2
Displaying information about VLAN groups
To display VLAN group configuration information, enter the following command.
BigIron RX# show vlan-group 10
Configured VLAN-Group entries : 1
Maximum VLAN-Group entries : 32
VLAN-GROUP 10
Number of VLANs: 4
VLANs: 10 to 13
Tagged ports: ethe 3/1
The example shows configuration information for two VLAN groups, group 1 and group 2.
Syntax: show vlan-group [<group-id>]
