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.
First don't use switch or router addresses as ping points , these put low priority on ping response and will "always" be slower than you think it ahould be . always ping thru the device such as pc to pc or pc to server etc .... Just make sure you aren't seeing errors on your uplinks or pc ports , look things such as duplex mismatches etc..... The cpu utilization on the 4006 is normal they all run in that area even with nothing attached to them .
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
