Hi Guys,
I have a 7600 connected to a CRS-1 via Giga Interfaces. The CRS is a "P"
router and the7600 is a "PE" router. The 7600 has two line card:
WS-X6724-SFP and WS-X6748-GE-TX. We're using the x6724 for Uplink to CRS and
the x6748 connect to internal devices via 802.1Q trunks. I've configured
policy maps applied to the vlan interface in order to set MPLS experimental
bits per vlan. Here the relevant configuration:
mls qos
!
policy-map SET-EXP-SIG
class class-default
set mpls experimental imposition 6
!
!
interface GigabitEthernet1/3
description #### to CRS ####
wrr-queue bandwidth percent 60 40
wrr-queue cos-map 1 1 5
wrr-queue cos-map 2 1 0 1 4
wrr-queue cos-map 2 2 2 3
priority-queue cos-map 1 6 7
!
interface Vlan120
ip vrf forwarding SIG
ip address 10.11.16.2 255.255.255.192
no ip redirects
no ip unreachables
service-policy input SET-EXP-SIG
end
interface GigabitEthernet1/5
switchport
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 120,122
switchport mode trunk
switchport nonegotiate
logging event link-status
logging event trunk-status
logging event spanning-tree status
load-interval 30
speed 1000
duplex full
mls qos vlan-based
mls qos trust extend
mls qos trust dscp
no cdp enable
spanning-tree link-type point-to-point
spanning-tree guard root
end
Unfortunately in the CRS we've noticed that the packets sourced in the
VLAN120 hasn't EXP bits 6.
Please any suggestion in order to solve this issue will be appreciated.
