Hello,
I have recently taken over a network and have a question about a current QoS
policy and am trying to understand why it would have been configured this way.
An excerpt of the questionable config is as follows:
policy-map apply_1000_qos_for_att_dscp_to_nextlevel
class EF_QOS_PORTS
police cir 4000000000 bc 3125000 be 31250000 conform-action
set-dscp-transmit ef exceed-action policed-dscp-transmit violate-action
policed-dscp-transmit
class af31_QOS_PORTS
police cir 4000000000 bc 31250000 be 31250000 conform-action
set-dscp-transmit af31 exceed-action policed-dscp-transmit violate-action
policed-dscp-transmit
class af21_QOS_PORTS
police cir 1000000000 bc 31250000 be 31250000 conform-action
set-dscp-transmit af21 exceed-action policed-dscp-transmit violate-action
policed-dscp-transmit
!
The above policy has been applied to all Gig interfaces on the 6509 blades.
What I'm trying to understand is the CIR / BC / BE settings and exactly what
they will achieve.
My first initial thought is that the CIR/BC/BE settings will achieve nothing?
Thanks!
Craig
