Re: LAN

If the LAN interface on router is displaying high value of broadcast, how could I identify which particular IP is source for that broadcast

Re: LAN

You can snif a LAN interface of the switch the Router is connected to.

Make sure you sniff in the same VLAN eq broadcastdomain here. If you realy experience a high volume of broadcast from just One host (not likely), it should be visible this way.

Download a sniffer program such as "ethereal"

Hi

If your physical layer is ok, please verify the CPU of your switches and routers.

Routers with higher cpu utilization (above 95%) sometimes can drop or delay packets.

Re: LAN

also make sure that stp is running on all the switches and unplug the hub for a while.
