IP

Layer 3 Management > IP > VLAN Interface

• Select—select the VLAN Interface for which configuration needs to be modified or deleted.
• VLAN Interface—enter the VLAN/VFI ID for the Interface to be created. The value ranges from 1 to 65535.
  • <vlan –id>—this is a unique value that represents the specific VLAN. This value ranges from 1 to 4094
  • <vfi-id>—VFI ID is a VLAN created in the system which contains Pseudo wires and attachment Circuits as member ports. This creates a logical LAN for the VPLS service. This value ranges from 4096 to 65535.
    Note:

    The VLAN ID 4095 is reserved and may be used to indicate a wildcard match for the VID in management operations or Filtering Database entries.

    VFI IDs 4096 and 4097 are reserved identifiers used in MPLS PW.

    The theoretical maximum for the maximum number of VFI is 65535 but the actual number of VFI supported is a sizing constant. Based on this, the maximum number of VFI ID accepted in the management interface is restricted. For example, if 100 VFIs are supported, the maximum number of VFI supported will be restricted to maximum number of VLANs + 100. An error message is displayed for any value beyond this range.
