We have been implementing distributed QOS in a 7507 with RSP4 and 128 MB of RAM. The VIPs are VIP2-40 with 32 MB of RAM.
The QOS has been implemented in subinterfaces of a HSSI. Encapsulation is frame relay and the CIR is 64Kb.
We have observed that putting even just one of the subinterfaces under heavy load, routing updates send throught it are lost and thus communication. Further investigation showed that VIP's CPU usage was 100% since heavy load started with QOS on place but was negligible without it.
Has anyone had problems like this? Does anyone have an idea of suggested HW requirements for distributed QOS?
We are pleased to announce availability of Beta software for 16.6.3. 16.6.3 will be the second rebuild on the 16.6 release train targeted towards Catalyst 9500/9400/9300/3850/3650 switching platforms. We are looking for early feedback from custome...
