Linear random early detection (RED) profiles define CoS virtual circuit drop profiles. You can configure up to 32 linear RED profiles per port. When a packet arrives, RED checks the queue fill level. If the fill level corresponds to a nonzero drop probability, the RED algorithm determines whether to drop the arriving packet.
To configure linear RED profiles, include the linear-red-profiles statement at the [edit interfaces at-fpc/pic/port atm-options] hierarchy level:
- [edit interfaces at-fpc/pic/port atm-options]
- linear-red-profiles profile-name {
- high-plp-max-threshold percent;
- low-plp-max-threshold percent;
- queue-depth cells high-plp-threshold percent low-plp-threshold percent;
- }
The queue-depth, high-plp-threshold, and low-plp-threshold statements are mandatory.
You can define the following options for each RED profile:
