VLAN groups
11
Use 1 – 32 for <num> parameter with the vlan-group command specifies the VLAN group ID
and can be from.
The vlan <vlan-id> to <vlan-id> parameters specify a continuous range (with no gaps) of VLAN
IDs that have not been configured in the CLI. Specify the low VLAN ID first and the high VLAN
ID second. The command adds all the VLANs in the range to the VLAN group.
If a VLAN within the range you specify is already configured, the CLI does not add the group but
instead displays an error message. If this happens, create the group by specifying a valid
contiguous range that does not include the VLAN. Then add more VLANs to the group after the
CLI changes to the configuration level for the group.
NOTE
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.
