Quality of Service

Enable or disable WRED support. WRED adds further protection for data integrity in a contention based Ethernet network by randomly discarding TCP packets according to administrator settable parameters for thresholds.

network qos wred config min-discard <min-discard> max-discard <max-discard>

Set the rate at which Ethernet frames will be discarded once the rate exceeds the thresholds. Note that two discard rates are supported. Min-discard is the rate that frames are discarded when they reach the minimum configured threshold. Max-discard is the rate that frames are discarded when they reach the maximum configured threshold. Often, the max-discard rate will be set to 100.

network qos interface wred <eth<1-2>port<1-25>(interface-id)> <queue lowmediumhighcritical> <min-threshold 1- 100> <max-threshold 1-100>

Set the minimum and maximum buffer threshold for each queue, on each port. Once either threshold is crossed, frames are discarded at the discard rates specified by the network qos wred config command.

Dynamic packet classification

In dynamic mode, packets are classified by the 802.1P Ethernet precedence bit or IP TOS (precedence bits) in the Diffserv byte. This definition is taken from the latest RFC 2475. Note that the IP TOS bits are defined as the three most significant bits of the DiffServ byte.

Ethernet frames are mapped to transmission queues based on the following chart:
