Hi, We've got a 7609 with ES20+ card in it (running SRD4 if it matters). We've got a service from a carrier that is sub-linerate so we would normally shape the sub-int to the speed of the service provided and then apply a child policy for the QoS.
The question I have is whether you can have an aggregate shaper across two interfaces because for some of the services we have a VLAN that is terminated on a L3 dot1q sub-int as well an an EVC that bridges another VLAN (on the same service from the carrier). The config from this setup is below. I can obviously apply a qos-policy separately to both interfaces, but that means I need to decide on the split of traffic between the two inner VLANs and neither of them will be able to use the full bandwidth of the link (and it will be a fixed split). Is there a way to do any sort of aggregate QoS over multiple VLAN's on the ES20 cards ? I know that for most other cards the answer is NO, I'm just curious if the ES20 has any pleasant suprises in this area that I haven't come across yet as I've only been playing with them for about 6 months and haven't delved too deep into their capabilities. I should note that there are lots of other services from the carrier delivered on the same interface (with different outer VLAN tag to identify each service), so using a 3-tier heirarchical QoS policy is not something that could be done. Thanks, Tony. outer tag (from carrier) = 1451 inner tag (from us) = 585 & 583 interface GigabitEthernet3/2 service instance 585 ethernet encapsulation dot1q 1451 second-dot1q 585 rewrite ingress tag pop 2 symmetric bridge-domain 530 ! interface GigabitEthernet3/2.14510583 encapsulation dot1Q 1451 second-dot1q 583 ip address x.x.x.x/30 _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
