Apologies, but it seems to have messed up my formating... trying again...
I am looking for some clarification on QoS on the ASR9K with respect to VLANs
and aggregate policing. I have 3 VLANs running over a Bundle and I am receiving
unmarked traffic that I need to unconditionally mark based on VLAN.
(I have omitted the ingress policy-map and class-map syntax for brevity so I
hope the following makes sense)
interface Bundle-Ether100.101
set dscp cs2
!
interface Bundle-Ether100.102
priority level 1
police rate percent 50
set dscp ef
!
interface Bundle-Ether100.103
priority level 1
police rate percent 50
set dscp ef
!
I am receiving EF traffic on two different sub-interfaces but I don't want to
receive more than 50% EF in total on each of the physical interfaces in the
Bundle. I am unable to apply the policy to the main Bundle interface as I need
to mark traffic based on a per VLAN basis (ok, I could probably match vlan in
that scenario). However, it is my understanding that this is what a Shared
Policy Instance is meant for and was wondering if the following would give my
desired result?
interface Bundle-Ether100.101
set dscp cs2
!
interface Bundle-Ether100.102
priority level 1
police rate percent 50
set dscp ef
shared-policy-instance SPI-EF50
!
interface Bundle-Ether100.103
priority level 1
police rate percent 50
set dscp ef
shared-policy-instance SPI-EF50
!
I would tie both the two policies attached to the EF VLANs to the same SPI -
would this limit my EF traffic to 50% of the total physical bandwidth or would
this not give me my desired result?
Thanks in advance,
Chris
(as a side note, how come 'puck.nether.net' rejects messages when I attempt to
post to the list from a subscribed Google Mail address? They are getting
rejected with the following message:

How come it needs a Username/Password when delivering to the MX?)
