[c-nsp] QoS and the Catalyst 4506e

[Steven Pfister]

I think I almost got it... is there any equivalent for aggregate policers for the Sup6e QoS? I've got something in the config now, but I'm not sure it's really going to have the desired effect.

Hi Steve,

I can't see any mention of aggregate policers for the Sup 6, but I could be
being blind:

http://www.cisco.com/en/US/partner/docs/switches/lan/catalyst4500/12.2/52sg/configuration/guide/qos.html#wp1474085 

If you want dbl then I believe you have to enable under each class entry you
want it on.

There is no equivalent to the tx-queue, think of each class entry in the
policy map as a queue. You can make one of the eight possible classes an LLQ
by configuring 'priority' under the class entry.

Regards,

Sam
