Usage Guidelines

Usage Scenario

In L2TP scenarios, an LAC processes PPP packets sent from an LNS with high priority. However, downstream switches cannot process high-priority packets. To enable BA classification for PPP packets so that the packet priorities can be adjusted, run the trust upstream priority command.

Precautions

This command takes effect only on the LAC.
