cable dot1q-vc-map
To map a cable modem to a particular Virtual Local Area Network (VLAN) on a local outbound Ethernet
interface, use the cable dot1q-vc-map command in global configuration mode. To remove this mapping,
or to remove a particular customer's name from the internal tables, use the no form of this command.

Usage Guidelines
This command maps a cable modem, on the basis of its hardware (MAC) address, to a particular
IEEE 802.1Q VLAN on a particular outbound Ethernet interface. This enables the cable modem's traffic
to be part of a virtual LAN at the Layer-2 level.

cable dot1q-vc-map mac-address ethernet-interface vlan-id [cust-name]
no cable dot1q-vc-map mac-address
no cable dot1q-vc-map customer cust-name
Specifies the hardware (MAC) address for the cable modem whose traffic is
to be mapped.
Specifies the outbound interface to which this cable modem should be
mapped. On the Cisco uBR7100 series and Cisco uBR7246VXR routers,
you can specify an Ethernet, Fast Ethernet, or Gigabit Ethernet interface,
depending on what interfaces are actually installed in the chassis.
Specifies the ID for the IEEE 802.1Q Virtual Local Area Network (VLAN)
that should be used to tag the frames for this cable modem. The valid range
is 1 to 4095, with no default.
Note
(Optional) Identifies the customer using this VLAN. The cust-name can be
any arbitrary alphanumeric string, up to 127 characters long.
(Optional) Deletes all VCs belong to this customer. The cust-name can be
any arbitrary alphanumeric string, up to 127 characters long.
Modification
This command was introduced for Cisco uBR7246VXR universal
broadband routers.
The switches acting as the bridge aggregators might support a lower
number of VLAN IDs. If so, the Cisco CMTS should be configured
within the limits of the switches' maximum number of VLANs.
