  vlan (VLAN configuration)
vlan (VLAN configuration)
Use the vlan VLAN configuration command to configure VLAN characteristics for a normal-range 
VLAN (VLAN IDs 1 to 1005) in the VLAN database. You access VLAN configuration mode by entering 
the 
vlan database privileged EXEC command. Use the no form of this command without additional 
parameters to delete a VLAN. Use the no form with parameters to change its configured characteristics.

Extended-range VLANs (with VLAN IDs from 1006 to 4094) cannot be added or modified by using 
these commands. To add extended-range VLANs, use the 
vlan (global configuration) command to enter 
config-vlan mode.
Note The switch supports only Ethernet ports. You configure only FDDI and Token Ring media-specific 
characteristics for VLAN Trunking Protocol (VTP) global advertisements to other switches. These 
VLANs are locally suspended.
Syntax Description vlan-id ID of the configured VLAN. The range is 1 to 1005 and must be unique 
within the administrative domain. Do not enter leading zeros.
are are-number (Optional) Specify the maximum number of all-routes explorer (ARE) 
hops for this VLAN. This keyword applies only to TrCRF VLANs. The 
range is 0 to 13. If no value is entered, 0 is assumed to be the maximum.
backupcrf {enable | disable} (Optional) Specify the backup CRF mode. This keyword applies only 
to TrCRF VLANs.
  • enable backup CRF mode for this VLAN.
  • disable backup CRF mode for this VLAN.
bridge bridge-number| 
 
type {srb | srt}
(Optional) Specify the logical distributed source-routing bridge, the 
bridge that interconnects all logical rings having this VLAN as a parent 
VLAN in FDDI-NET, Token Ring-NET, and TrBRF VLANs. 
The range is 0 to 15. 
The type keyword applies only to TrCRF VLANs and is one of these:
  • srb (source-route bridging) 
  • srt (source-route transparent) bridging VLAN
