PPPoE over VLAN Enhancements: Configuration Limit Removal and ATM Support
Cisco IOS Release XE 3.9S
The PPPoE over VLAN Enhancements: Configuration Limit Removal and ATM Support feature provides two enhancements to PPP over Ethernet (PPPoE) over IEEE 802.1Q VLAN functionality:
It removes the requirement for each PPPoE VLAN to be created on a subinterface. Removal of this requirement increases the number of VLANs that can be configured on a router to 4000 VLANs per interface.
It adds ATM permanent virtual circuit (PVC) support for PPPoE over VLAN traffic that uses bridged RFC 1483 encapsulation.
In Cisco IOS Release 12.2(31)SRC, this feature was introduced.
In Cisco IOS Release 12.3(2)T, this feature was integrated into the T train.
In Cisco IOS Release 12.2(33)SB, support was added for the Cisco IOS 10000 series routers.
The following commands were introduced or modified:
clear pppoe , debug pppoe, pppoe enable, protocol pppovlan dot1q, vlan-id dot1q, vlan-range dot1q.
