3com 4500g switch having issues with bpdu packets being sent to our Core Cisco Switch, PLZ HELP

 

3com 4500g switch having issues with bpdu packets being sent to our Core Cisco Switch, PLZ HELP

So the 3com swtich is sending bpdu packets to our core cisco switch on ports 1/0/51 and 1/0/52, I wanted someone to look at my configuration to see if I need to add anything to disabled sending bpdu packets to our core cisco switch because the core cisco switch doesn't like bpdu packets and will shutoff the ports if it detects it.

Re: 3com 4500g switch having issues with bpdu packets being sent to our Core Cisco Switch, PLZ HELP

Actually, You can use bpdu-drop any command at 4500 or bpdufilter enable at Cisco.

 

But in that case You can have lots of trouble in your network, because of banned stp...

Re: 3com 4500g switch having issues with bpdu packets being sent to our Core Cisco Switch, PLZ HELP

i did the following to all the ports

 

int g 1/0/1 all the way through 1/0/48

 

bpdu-drop any

 

in addition, i did a stp bpdu-protection on the entire switch

 

and... I did a stp disable on the entire switch

 

Didnt work. Any thoughts?

Re: 3com 4500g switch having issues with bpdu packets being sent to our Core Cisco Switch, PLZ HELP

why did you ban the bpdu at your core switch on the port looking at your switch?

do you use bpduguard for it ?

 

Re: 3com 4500g switch having issues with bpdu packets being sent to our Core Cisco Switch, PLZ HELP

i dont manage the cisco core switch. the network team manages that. they said if the cisco detects a bpdu packets it will disable the ports to the 3com switch.
