Thing is the other switch does not have neither enabled.. Could it be the metro-e carriers have a switch somewhere in between which sends bpdu's out?

- Thanks

This is generally only applicable on interfaces with portfast turned on so I would check to make sure portfast is not turned on for that link , if it is and its a connecting link to another networking device turn it off . It looks like it has err-disable recovery turned on also so every once in awhile it will try to reenable g0/25 but when it does it see bpdus fromn the other end so it shuts it off again . Check G0/25 and make sure portfast is not turned on . You also have native vlan mismatches but I can't tell what port that is by the display.]]> http://www.dslreports.com/forum/remark,19878567 Sat, 26 Jan 2008 13:23:25 EDT [HELP] Cisco 3560 Errors http://www.dslreports.com/forum/remark,19878472 Tyrell : I have two sites connected through metro-e, however one of the 3560 is showing the following errors. Can someone please tell me what is going, currently I cannot get into this switch as it managed by another vendor, however, I'm trying to get as much information as possible as to why this is accuring.

Currently, gi0/25 is recieving the fiber connection and shows a link light for a short period of time but goes out after 2 seconds.

Any suggestions would be greatly appreciated.

- Thanks.
