I think you are going to struggle getting the Huawei 5600 to back up
correctly in RANCID I'm afraid. The problem with Huawei is that they have
very different CLIs across their product range. In fact, on their MSANs you
see significant differences between the CLI of the data cards and the voice
cards and neither of these have a CLI which is the same the that on their
switches or firewalls. I suspect the RANCID script you are using was
designed for switches and firewalls rather than the 5600 DSLAM. Some of the
major differences are how the CLI handles things like turning off paging (I
seem to remember at least some of their kit not supporting disabling
paging) and the string that is output to inform the user of the end of a
page (which RANCID uses internally if paging support cannot be disabled). I
also seem to remember the DSLAMs spitting out all kinds of horrible control
character which make your RANCID backups look a total mess. We've been
through this process where I work and in the end we decided to just give up
on the idea of using RANCID to backup the Huawei DSLAMs and MSANs and
backed up the configs to a TFTP server instead (I think that's the only
server type they supported on the code we run). Unless you are fairly handy
at perl and tcl or know someone who is and have time to spend a lot of time
digging around in the code for the plugin, I'd suggest doing the same to
save yourself some massive headaches!
