Hello List! We have 2 7206VXR-NPEG2 routers in different towns (T1 and T2), with the same configuration template, same IOS - 12.2(31)SB11. Each of them have one interface for client's services termination; one for transport connection to core routers (P router). The challenge is : traffic load on T1 is twice as much on T2, but the CPU load is almost the same. Details: 1) There are the same number/load of Internet services with uRPF enabled on both routers 2) The same number acls 3) In "sh proc cpu sorted" the main cycles are used for packet forwarding -------------------------------------------------------------------------- Here are some outputs from T2 (less traffic, same CPU load),uplink, 5 minutes after cleared counters: T2#sh int gi0/2 | i 30 30 second input rate 459618000 bits/sec, 74812 packets/sec 30 second output rate 276334000 bits/sec, 59440 packets/sec T2#sh int gi0/2 | i queue Input queue: 0/1000/0/0 (size/max/drops/flushes); Total output drops: 0 Output queue: 0/1000/0 (size/max total/drops) T2#sh int gi0/2 | i queue Input queue: 0/1000/0/0 (size/max/drops/flushes); Total output drops: 0
Here are some outputs from T1 (more traffic, same CPU load),uplink, 5 minutes after cleared counters: T1# sh int gi0/2 | i 30 30 second input rate 780209000 bits/sec, 111772 packets/sec 30 second output rate 356832000 bits/sec, 105820 packets/sec T1# sh int gi0/2 | i queue Input queue: 1/75/0/0 (size/max/drops/flushes); Total output drops: 0 Output queue: 0/40 (size/max) T1# sh int gi0/2 | i error 0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored 0 output errors, 0 collisions, 0 interface resets -------------------------------------------------------------------------- Any suggestions are appreciated.
