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.
Best regards,
Olga
