how to know the load on router processor from ip policy and access lists ?

hi ,

today i installed new router 7600 , but im facing some thing .

the cpu is increasing and it reached 50 %

and still increasing as the bw dissipated is increasing .

im applying ip policy which set next hop for many internet source

my question is , how to know the cu percentage which is used by this ip policy ,

also , how to know the percentage by access-list ??

regards

Hi Ahmed,

You can have these check for specific to you Access policy.

hi ,

it seems that all process utilize 0 % !!!!!!!!!!!!!!!!!!!!

i did the following :

Gateway7600#sh processes cpu sorted | i tcp

Gateway7600#sh processes cpu sorted | i policy

217           4       10687          0  0.00%  0.00%  0.00%   0 ACE policy loade

Hi Ahmed,

you need to state ... | include IP to get all the statements about the ACL. Remember that a 7600 is a quite powerful machines and the show proc command has not a very precise approximation to the computational commitment (just 0.00%). Apart this, you need to generate some traffic that you are sure will hit the ACL to really create ssome statistics about your load and the ACL order it is important too. If you wrote the ACL statements in the proper order , the 7600 will filter the traffic in the very first lines of your acl without reading the rest. This is not going to impact the CPU so much to show in the proc statistics.

have a nice day
