I currently have 2 7206 VXR routers with NPE-G2's in them. One of them is running a POS OC3, doing about 125Mbps inbound with 1Mbps outbound. This is the termination point for en eBGP peer, with a 5 line ACL on the interface also. I am seeing close to 85% CPU usage on this router, which seems to be extremely high, with only 80Kpps going through the OC3. I was wondering if anyone has experienced this problem with POS interfaces with the 7206 NPE-G2, I am running cef.
To compare, our second 7206 has a GigE connection to another eBGP peer, which runs roughly 100Mbps inbound and 175Mbps outbound, same setup, just using a GigE interface, and the CPU usage is roughly 45%.
We shifted all of the OC3 Bandwidth over to the other 7206, by turning down that eBGP peer, and now that GigE connection runs at roughly 310Mbps inbound and 250Mpbs outbound, with 75% CPU.
My main concern is these NPE-G2's are supposed to be able to handle 800Mbps or so, and at 75% CPU, this seems to be untrue.
Has anyone seen similar problems with the G2's?
