[c-nsp] 7600 Rate Limiting Output

[Kevin Warwashana]

I have the same config as your example, but created the additional
policy-map first in order to apply it.  It didn't take so it was missing
from policy-map 26MB-OUTPUT.  Looks to be a feature limitation of the
SIP-600.

I am running 12.2.33 SRD3.  Looks like my only option is to shape and not
police egress.

Thanks,
Kevin

What I meant was this:

policy-map RJS-TEST
  class class-default
    shape average 30000000
   service-policy RJS-CHILD-TEST
!
policy-map RJS-CHILD-TEST
  class class-default
   police cir 26000000 conform-action transmit exceed-action drop
!

Which is something that one can apply on SIP-400:

7600#sh run int giga1/0/0.4011
Building configuration...

Current configuration : 239 bytes
!
interface GigabitEthernet1/0/0.4011
 encapsulation dot1Q 4011
 ip address 192.168.88.42 255.255.255.0
 ip vrf forwarding RJS-TEST
 shutdown
 service-policy input POLICY-SET-IP-DSCP-DEFAULT
 service-policy output RJS-TEST
end

Out of interest - what IOS are you running on the 7600 in question?

Kind regards,
Rob
