Description

Use this command to create a Random Early Discard (RED) profile and provides a minimum
threshold, maximum threshold, and drop-probability for egress traffic flow.

Usage Guidelines

Enter qos random-detect cos command while in configuration mode for a specific interface to map
the profile to a CoS priority for a port.

Enter no qos random-detect cos command while in the interface mode to remove the profile from
the interface. You must remove the profile from interface before you can remove the profile itself.

Enter no qos red-profile profile-ID to remove the profile while in global configuration mode.

NOTE

This command is only supported on Brocade VDX 8770-4, VDX 8770-8, and later switches.

Examples

To create a RED profile while in global configuration mode:

switch# configure terminal

Entering configuration mode terminal

switch(config)# qos red-profile 2 min-threshold 10 max-threshold 80

drop-probability 80

To remove the profile while in global configuration mode:

switch(config)# no qos red-profile 2
