Hi, All!
I have the folowing porblem on Cisco 7600 with RSP720-3CXL-GE.
IOS 12.2(33)SRD4 Advanced IP Services
From config:
!
policy-map xxxxxx
class class-default
police cir 10240000 bc 1920000 be 3840000
conform-action transmit
exceed-action drop
violate-action drop
!
!
interface VlanYYY
description Some Customer
ip address x.x.x.x 255.255.255.252
no ip redirects
ip flow ingress
no snmp trap link-status
service-policy input xxxxxx
service-policy output xxxxxx
end
!
Before upgrade we has only CFC-capble line cards in it
(WS-X6748-SFP, WS-X6704-10GE) and actual rate on customers
interfaces was according policy-maps.
Recently 4-port 10G card WS-X6704-10GE was replaced by
WS-X6708-10GE with DFC (WS-F6700-DFC3CXL).
Incoming traffic comes via CFC line cards and via this
10GE DFC line card. So, on customer interface we have
some time nearly doubled rate.
I have read some docs on cisco.com and found explanation
how policyng works in such situation - each DFC-capable
linecard process service policy independently on ingress.
#sh policy-map int vlan YYY
...
Service-policy output: xxxxxx
class-map: class-default (match-any)
Match: any
police :
10240000 bps 1920000 limit 1920000 extended limit
Earl in slot 2 :
108929538743 bytes
5 minute offered rate 72568 bps
aggregate-forwarded 108895170086 bytes action: transmit
exceeded 34368657 bytes action: drop
aggregate-forward 65368 bps exceed 0 bps
Earl in slot 5 :
252903936350 bytes
5 minute offered rate 101144 bps
aggregate-forwarded 252600188727 bytes action: transmit
exceeded 303747623 bytes action: drop
aggregate-forward 56304 bps exceed 0 bps
#
I try add command mls qos bridged but it doesn't help.
So the question is: Is it possible in some way to solve such
situation and control egress rate to customers with DFC line
cards?
Still trying to find any hints in Google... without success. :(
Thanks in advance!
