Log in to a800 with telnet, from quintum> prompt type
config unit 1
ip xxx.xxx.xxx.xxx (xxx.xxx.xxx.xxx = ip address).
exit
exit
If you need to change the subnet and def gateway, do the following;
syslan
sub xxx.xxx.xxx.xxx
def xxx.xxx.xxx.xxx
exit
From Config# prompt type
submit
Then restart tenor.
I also suggest that you go to quintum’s web site, go under support and download the CLI command reference guide for the a800 as this command and all others are listed there.
