Hi Bob,
Thanks a bunch for the reply and the link. I've got another question. Hope
you would help me answer this one too.
This question is about Traffic Classification on a Per-Port-Per-VLAN Basis
using Class maps
My switch's port fa0/1 is assigned to VLAN 10. I want to Mark all packets on
VLAN 10 with IP precedence critical.
As per Cisco's documentation on this, I configured it as follows: (Pls
correct me if I've configured it wrongly)
mls qos
class-map match-all TRAFFIC
match access-group 1
class-map match-all Per-Port
match vlan 10
match class-map TRAFFIC
!
policy-map QoS
class Per-Port
set precedence 5
access-list 1 permit any
int fa0/1
service policy input QoS
Thanks in advance,
cheers!!!
Salman
