Subject: [enterasys] Linkflap C2 / E1
Does anyone have experience with the Linkflap function?
We currently have a problem that is difficult to identify source. There is a
optical wireless link between a C2 Stack and an E1. The Link often fails due to
atmospheric factors, and the end-to-end link goes unusable even after the link
gets back up. By our experience, the link at first drops a few packets (doing a
"PING -T x.x.x.x") then goes completely unusable, dropping every packet. The
logging buffer doesn't record anything useful regarding the specific port. The
firmware installed is 03.07.29.0000 on the E1 and 05.01.03.0003 on the C2.
Until now, the only way we have devised to get the link back up is by doing a
manual reset to the link, either disconnecting the cable physically and
plugging it back in or doing a "set port disable ge.x.x" and "set port enable
ge.x.x".
If the Linkflap could solve the problem I would be off the hook. Anyone has
experience on these kind of issues? Another option is maybe having a script
executing the port disable/enable on its own. Does anyone know how to run
commands on a switch automatically, or through "unmanned" telnet sessions? Any
kind of software that could accept scripts and run them in a telnet session
automatically in case the links goes "flapping" again...
Thanks everyone!
