Hello,
I've two WS-C2950G-48-EI in the stack and few other cat2950 in star topology uplinked by fastethernet. What I just see now is constantly the gigabitethernet is going up&down. I found on cisco:
http://www.cisco.com/en/US/products/hw/modules/ps872/products_module_installation_guide_chapter09186a008007d1e4.html
and tried to put command :no gigastack loop-breaking [interface-id] global configuration command - but switch didn't recognize this command. Next thing - theses two switches running the same iso Version 12.1(12c)EA1, but the others(which are not in stack Version 12.1(9)EA1) - cisco papers says that all switches shoud run the same ios - does also the ones which are not in stack shoud be upgraded ??
Please give me any advice.
TIA,
Mark
here are the logs :
1y3w: %LINK-3-UPDOWN: Interface GigabitEthernet0/2, changed state to up
1y3w: %GIGASTACK-1-NO_LOOP_DETECT: The link neighbor of link 1 of Gigastack GBIC
in Gi0/2 did not respond to the loop detection request. If loop topology is dep
loyed, make sure all switches in the stack are running the latest software.
