There are 4 VLAN's . switching comprises of CISCO 4006 cataylst with supervisor engine II as CORE switch , twelve cisco catalyst 3500 series XL( in one building ) and seven 3550 series catalyst as edge switches The backbone connectivity of all switches is through fibre optics .There are 4 VLANS in use ( grouping is based on IP range )
When we ping from one of the PC in any of the VLAN to the switches we are getting a time delay of more than 40ms
The following is the result which I got for a continuous ping at one of the edge switches at XYZ building ( 3500 XL)
Following is the :CPU utilization of the core switch :-
CPU utilization for five seconds: 18.75%
one minute: 19.00%
five minutes: 19.00%
We would like to get clarified on the following points
Is this latency acceptable, if yes then can we get supporting documents regarding it.
Thanks in advance
