Hi folks,
I've a topology like that:
customer: 3550
aggregator: 4500
backbone: 6500
on 3550 and 6500 I work with DSCP values. Between 3550 and 4500, and 4500-6500, I've trunks. Normally the 4000 family creates the "internal DSCP" value for egress policies using DSCP for IP-traffic, and using CoS for non-IP and for traffic from trunks. That is packets have my DSCP value in ingress, but a DSCP-to-CoS in egress.
Question: there's a way to have the same DSCP value in ingress and egress on 4500 for traffic trunked?
<edit> better:
1- after internal DSCP egress policies, the packet has a CoS-to-DSCP value, or the original DSCP value?
2- if Cos-to-DSCP value:
http://www.cisco.com/en/US/products/hw/switches/ps663/products_tech_note09186a00800946e9.shtml
"Egress policy cannot match new QoS levels that are changed by ingress marking."
If I remark the ingress traffic with a service-policy in input, I see that DSCP value after egress policies?
</edit>
Any advice will be appreciated
Best Regards
Andrea
