Excessive Broadcasts on trunk

[The-Dealman]

I have 2 2810-48g switches  one at the top of the rack & the other about 25 feet away linked together via 4 cat5 cables in a trunk. The config below comes from the top of the rack switch where i get Excessive Broadcasts errors on all 4 ports in the web interface. What can i do to fix the Excessive Broadcasts ?

Do a "show trunk" for us, from both switches.

Do a "show cpu".

[The-Dealman]

Ok here you go, switch 5 uplinks to switch 6

I downloaded a monitoring app & added those switches to it. After a few hours i started to notice that there is a port flapping issue on the switch that is in the rack. looking over the config again it looks like spanning-tree is turned on the trunks but if i do a sh spanning-tree or sh spanning-tree detail it it shows that it's not enabled

[Vince_Whirlwind]

sh spanning-tree trk2?

sh int br 45-48?

[The-Dealman]

Here you go

Switch 6(config)# sh spanning-tree trk2

[The-Dealman]

Anyone have ideas on this?

[Vince_Whirlwind]

Everything looks fine.

(Although, I'd enable spanning-tree, personally.)

What is the GUI telling you, exactly?

[The-Dealman]

Excessive Broadcasts on ports on all the links in the trunks. I noticed that one of the interfaces doesnt have activity on it #46
