Hi folks,
I am converting from Cisco 2511 terminal servers to Avocent ACS6048
terminal servers. I have been using the Cisco terminal servers for
years without issues on a variety of Sun and HP servers, disk arrays,
and various other hardware. However, I can't seem to get the Avocent
terminal servers to work properly. I am unable to get any response from
a connected device via conserver. However, I can access the device just
fine using telnet directly to the Avocent port. I do get a response if
the Avocent port is put in raw mode but sending a L0 break doesn't get
to the device. Sending break from telnet works just fine. Clearly I am
missing something. I did set portbase to 7000 for the Avocent as
recommended in an archived post but that did not fix this issue.
See below my conserver and console .cf files, sample working Cisco port
config and a sample non-working Avocent port config. Any assistance is
very much appreciated.
