Hi,
We have:
(Cisco Controller) >show udi
NAME: "Chassis" , DESCR: "Cisco Wireless Controller"
PID: WS-C3750G-24WS-S25, VID: V02, SN: FOCxxxxxxx
(Cisco Controller) >show sysinfo
Manufacturer's Name.............................. Cisco Systems Inc.
Product Name..................................... Cisco Controller
Product Version.................................. 5.2.193.0
RTOS Version..................................... 5.2.193.0
Bootloader Version............................... 4.0.217.0
Emergency Image Version.......................... 5.2.157.0
...
This box has a prompt as show above `(Cisco Controller) >' and non
standard command to disable paging:
config paging disable
so a standard clogin can't handle it.
I found a post
http://www.shrubbery.net/pipermail/rancid-discuss/2010-February/004652.html
and start with attached wlogin and ciscowlc5, many thanks for this
starting point to Jeremy.
The original wlogin not used disabled paging and the stupid box did
paging in the middle of the line. Fortunately I found the command above
for disabling paging. After learning expect a bit :) I took original clogin
from Rancid, strip down enable mode and apply the different prompt and
command to disable paging. I modify a little ciscowlc5, so it can be
used with http://sites.google.com/site/jrbinks/code/rancid/wraprancid.
My versions of files wlogin and ciscowlc5 are attached. Hope it can be
useful for someone.
I'm not subscribed on this list, so keep me in the Cc please if I should
receive a reply..
Regards
