We are replacing some Extreme switches with Cisco 2960S-48 switches.
We ran ELRP on the Extreme switches to prevent loops.
Looking at the Cisco options I am a bit confused as to what option to use or multiple options.
I read that BPDU guard may not be enough to prevent loops. Maybe the storm control should be used. Loop guard ? UDLD ?
Here is the environment:
Several engineers hardware/software have small desktop switches as they plug in numerous devices and I don't want to limit the MAC count.
Two 1 Gig GBICS with be used as Etherchannel to the core.
Most user ports are access mode with a default vlan, data, and voice.
My main concern is to prevent users from looping the network with small switches. We also have the occasional person moving desks looping by plugging things in wrong.
UDLD and BPDU guard?
Example switch port or trunk port config ?
Thanks in advance
