Nexus 7000 QoS - Nortel

[Joshua Schmookler]

Has anybody here run a nortel CS1000E VoIP system through a Nexus 7000? If so, can you shed some light on your QoS configuration? (Did you re-mark the DSCP values? Trust CoS? What DSCP's did you use for signaling and payload? etc...)

[Edison Ortiz · Accepted solution]

Did you re-mark the DSCP values? Trust CoS?

This answer depends on how much you trust your attached devices.

If you don't trust your devices, then you must remark the DSCP values even if they are sending the correct ones.

What DSCP's did you use for signaling and payload?

These are our recommendations for marking:
