QoS mapping and other things

Post by Spack » 14 Oct 2008 03:37

Hi all,

I would like to map packets that arrive on my switch with a certain DSCP flag to a certain ToS...

Here, I want to put ToS 1 for all DSCP 30 packets... To do that, I use these commands :

Code: Select all

policy map group "dscp30" 30:1
policy condition "isDSCP30" dscp 30
policy action "mapToToS1" map dscp to tos using "dscp30"
policy rule "30priority" condition "isDSCP30" action "mapToToS1"
qos apply
That seems correct for me any packets with the DSCP flag at 30 are mapped to ToS 1. But when I enter the policy rule command I get an error like this...
Error: 30priority: Cannot map from DSCP while classify on DSCP.
What am I doing wrong?

My other question, I have two OmniSwitch and on this ones, I am mirroring some ports but I have only one monitor so I would like to use a vlan of one of my switch like a hub... Any packets that arrive on this vlan are redistributed to all the port of the vlan...

How can I do that?

Hi,
it assumed to me that the special-dscp-condition is the reason for the error message. Try the same with an universal condition - like policy condition from-vl1 source vlan 1.

For your question with mirroring: there is a new feature (from 6.3.1 ??) remote port mirroring. This allows to mirror ports on an other 6850/9000. Maybe this is usefull for you.
