Spanning tree screw up
hello ppl I have a cat 5500 with 12 ethernet cards and an RSM over the weekend I repatched the whole network and added a couple new vlans...it all seems to work. However this message seems to come up occasionally %MLS-4-RESUMESC:Resume MLS after detecting too many moves %MLS-4-MOVEOVERFLOW:Too many moves, stop MLS for 5 sec (200) my telnet connection to the switch seems to disconnect when it feels like it (which is SO enjoyable when configuring VLANs :)) on looking through the Cisco Web Site, I understand that its a spanning tree problem. However, do any of you guys know if rebooting the switch would solve the problem ? and if not, what will ? Thanks Alex _ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com.

RE: Spanning tree screw up
i had a similar problem with a cat 5500 the problem was a encapsulation mismatch on a trunk. Correct the mismatch and the messagge go away (but for me wasn't occasionally but every 5 seconds) hope this help Stefano > -Original Message- > From: alex campbell [mailto:[EMAIL PROTECTED]] > Sent: giovedì 31 agosto 2000 14.52 > To: [EMAIL PROTECTED] > Subject: Spanning tree screw up > > > hello ppl > I have a cat 5500 with 12 ethernet cards and an RSM > over the weekend I repatched the whole network and added a couple new > vlans...it all seems to work. > However > > this message seems to come up occasionally > %MLS-4-RESUMESC:Resume MLS after detecting too many moves > %MLS-4-MOVEOVERFLOW:Too many moves, stop MLS for 5 sec (200) > > my telnet connection to the switch seems to disconnect when > it feels like it > (which is SO enjoyable when configuring VLANs :)) > on looking through the Cisco Web Site, I understand that its > a spanning tree > problem.

Re: Spanning tree screw up
Alex , "Move" means a mac/vlan in cam table changes its port index, usually it is caused by : 1/ misconfiguration . The switch to learn the same mac/vlan from two different ports in turns. 2/ spt loops Here is how you can get some insight in the problem ; If i recall correctly ; on the switch type 'show mls notification' You will get something like ; 1: (0005f9df-00023380) Noti Chg TA 1d9de OI 180 V 1 OI ===> port index it learns, take 4 high bits plus 1 = module number take 6 low bits plus 1 = port number TA ==> table address in the cam table . Now in the example ; OI 180 ===> 00011000 ^^ + 1 = port number + 1 = module number This case 7/1 . To find the mac address that causes the moves do : 'sh looktable < TA-value from above> This tells you the mac involving the moves and on what ports it is 'moving' . Next step is finding what/were this mac is . flem --- alex campbell <[EMAIL PROTECTED]> wrote: > hello ppl > I have a cat 5500 with 12 ethernet cards and an RSM > over the weekend I repatched the whole network and > added a couple new > vlans...it all seems to work. > However > > this message seems to come up occasionally > %MLS-4-RESUMESC:Resume MLS after detecting too many > moves > %MLS-4-MOVEOVERFLOW:Too many moves, stop MLS for 5 > sec (200) > > my telnet connection to the switch seems to > disconnect when it feels like it > (which is SO enjoyable when configuring VLANs :)) > on looking through the Cisco Web Site, I understand > that its a spanning tree > problem.
