On a 7206VXR with a NPE-G1 processor I am seeing input errors on a Gigabit Ethernet interface. The input errors are due to âignoredâ packets:
303 input errors, 0 CRC, 0 frame, 0 overrun, 303 ignored
The ignored packets coincide with âRX No Buffâ errors that appear in the output from a 'show controller' command:
RX No Buff 303
There is a about 30Mb/s of incoming traffic, mostly multicast, on the interface and according to the âshow processes cpu historyâ command the maximum CPU over the last 72 hours was 60% with an average CPU of 30% during peak times.
Can anyone provide suggestions on how to correct these errors or am I running up against the processing limits of this router? If so, are the âRX No Buffâ errors an indication of a limitation of the Gigabit Ethernet interface or the NPE-G1 CPU in the router? Would upgrading to a NPE-G2 correct the problem?
Any assistance would be appreciated.
