first thing to do is check to see what is going on ......
go onto the rsm and do a show interface....this sholud list all VIRTUAL
interface`s and see what is the amount of "Packets per second" going through
interface.
also check "5 mins traffic"...
you can download from "www.solarwinds.com" there package`s...in eval
go for the professioinal edition ...it has a tool called CPU load ...this
will give you an OVERALL picture of your RSM (aslong as you have assigned it
an IP address)...in real time...
also has "bandwidth Monitor" ..which can monitor VIRTUAL and REAL
interfaces...(again need ip address)
in order to fix this we need to know were all the traffic is
FIRST good thing to do is move ALL workstations of VLAN 1 ...this is a
managment VLAN and only switch/routers should use this .......
ALSO your trunks are they fibre or are they 100 meg....are your workstations
100meg ...if so to increase speed .....ETHERCHANNELL 3 or 4 TP ports for
3-400 meg throughput.
this is a good start ....try this and report back to the list ...and we will
go from there...
