Can anyone please explain what type of queing this is.
I placed this config on my 6513 routers.
class-map match-any C-VOICE-SIGNAL
description VoIP SIGNALLING
match ip dscp af31
match ip dscp cs3
class-map match-any C-VOICE
description VoIP TRAFFIC
match ip dscp ef
match protocol rtp audio
priority percent 40
bandwidth percent 5
and applied it to several interfaces.
When I check the interface I see this as the queing strategy. I know LLQ, CBWFQ, WFQ etc but is "VIP-based fair queuing" another flavour of LLQ?
I just thought I add this to show you were I see the Queueing strategy: VIP-based fair queuing.
This is a show interface

Hi, the VIP was the first cisco platform doing distributed processing.
Now, even if on a different architectures, they use the same term to indicate packet processing done by a line card processor rather than the central one.
So, there is nothing to worry about.
