We configured a input QoS policy on particular interface, where we are
forcing precendence, however noticed that the same is not being made.
In summary we have the following configuration:
RP/0/RP0/CPU0:CRS# sh run int hundredGigE 0/3/0/0
Mon May 14 16:19:54.009 DST
interface HundredGigE0/3/0/0
service-policy input XPTO
ipv4 bgp policy propagation input qos-group source
ipv4 address 10.10.10.1 255.255.255.252
ipv6 nd suppress-ra
carrier-delay up 5000 down 0
load-interval 30

RP/0/RP0/CPU0:CRS#sh cef 8.8.8.8
Mon May 14 16:20:33.329 DST
8.8.8.0/24, version 22, internal 0x4000001 (ptr 0x9e453b00) [1], 0x0 (0x0), 0x0 (0x0)
Updated May 8 08:20:04.329
Prefix Len 24, traffic index 0, precedence routine (0)
QoS Group: 10
via 10.10.10.2, 3 dependencies, recursive, bgp-ext [flags 0x20]
path-idx 0
next hop 10.10.10.2 via 10.10.10.0/30
As you can see here this prefix makes match on qos-group 10, so should be marked with a
precedence 1, but is marked with 0.
can help?

hi Luis,
Can you also supply the CEF hardware output, so we can check the precedence their as well. Use the CLI
"show cef 8.8.8.8 hardware ingress location 0/3/cpu0" and we'll look at the qos_precedence: value to see if it is also set to 0.
thx,
David
