Subscriber Session on Ambiguous VLANs

Subscriber Session on Ambiguous VLANs
Ambiguous VLAN enables you to create multiple subscriber sessions on a single access-interfaces. As a result,
it increases the scalability of the access-interface. An ambiguous VLAN is an L3 interface on which either a
VLAN ID range, or a group of individual VLAN IDs are specified. Instead of individually mapping each
subscriber to a VLAN, an ambiguous VLAN configuration performs the mapping for a group. Multiple
subscribers can be mapped on the ambiguous VLAN as long as they possess a unique MAC address. The
subscriber sessions created over ambiguous VLANs are identical to the ones created over regular VLANs,
and support all regular configurations such as policy-map, VRFs, QoS, access-control list, and so on.
For enabling IPoE subscriber session creation on an ambiguous VLAN, see
on Ambiguous VLANs, on page
Restriction
Ambiguous VLANs do not work with Unicast client.

Establishing Subscriber Session on Ambiguous VLANs

Perform this task to define an ambiguous VLAN and enable creation of IP subscriber session on it.
There is no DHCP-specific configuration required for ambiguous VLANs.
Note
SUMMARY STEPS
1. configure
2. interface type interface-path-id
3. Use any of these commands to configure encapsulated ambiguous VLANs:
4. ipv4 | ipv6address source-ip-address destination-ip-address
5. service-policy type control subscriber policy_name
6. ipsubscriber ipv4 l2-connected
7. initiator dhcp
8. Use the commit or end command.
