Configuring LNS CoS for Link Redundancy
You can configure multiple ports on the same IQ2 and IQ2E PICs to support link redundancy for CoS on L2TP tunnels configured on an Ethernet interface. Link redundancy is useful when the active port is unavailable due to events such as:
- Disconnection of the cable
- Rebooting of the remote end system
- Traffic re-routing through a different port due to network conditions
When link redundancy is enabled in such scenarios, the L2TP tunnels and its session are maintained by switching traffic to another port configured on the same IQ2 or IQ2E PIC.
To configure multiple ports (IQ and IQ2PE PIC) on an Ethernet interface for redundancy with CoS, configure per-session-scheduler for all Ethernet ports:
user@host#edit interfaces ge-2/0/0 unit 0 per-session-scheduler user@host#edit interfaces ge-2/0/1 unit 0 per-session-scheduler You can similarly configure all the ports on the IQ2 or IQ2E PIC to support link redundancy for CoS on L2TP tunnels.
