Restrictions for EtherChannel Flow-based Limited 1:1 Redundancy
When you are using the Cisco ASR 1001-X, the following restrictions apply for collecting traffic statistics for VLAN egress on sub-interfaces. Obtaining input/output counters using SNMP is unsupported. This is because the Cisco ASR 1001-X has a built-in SPA.
Restrictions that apply when obtaining traffic statistics for two types of interfaces are shown below:
For the Cisco ASR 1001-X, statistics for the VLAN egress are available for physical sub-interfaces. The output counter is used from cpp, not from the built-in SPA hardware. To show VLAN egress statistics, use the show vlans vlan id command.
# show vlans 10 VLAN ID: 10 (IEEE 802.1Q Encapsulation) > > Protocols Configured: Received: Transmitted: > IP 133 104
Port Channel sub-interfaces
For the Cisco ASR 1001-X, showing traffic statistics for the VLAN egress is not supported for port channel sub-interfaces.
cpp or the built-in SPA can not be used to give an output counter value for port channel sub-interfaces.
