Hi Joni (again),
The problem with "Unassigned" or "Not Present" stack elements in an
Enterasys network is not new for us. We have had several power outages
in the past and have had then the situation that random stack elements
failed
to restart when the power came back.
For chassis based systems I've added a special port_count attribute in
Spectrum
which is periodically checked again the actual port_counter; which
then alarms
us when the actual port_counter is less than what we expect.
In the case of Secure Stacks this construct does not work, because the
port_count
remains the same, even when you un-power one stack element. So we do
have
the same problem as you have. So this is a severe behaviour
distinction between
chassis based vs. stacked systems from Enterasys.
Best regard,
--Fritz.

I flipped a coin to look for "Unassigned" or "Not Present" -- I don't
think there's a difference in the results (not to date).
The other one I like to know about is whenever there are errors on the
stack connection because that stacking cable SHOULDN'T have errors.
cliConfig -l $LIST -telnetUser $USER -telnetPwd $PASSWD -c $CMDFILE |
grep -e "Up" -e "Down" -e host | awk -F" " '{ if ($1~"host") print $2;
else {if ($2=="Up" || $2=="Down") {if ($4+$5+$7+$8>0) print $0} else
{if
($3+$4+$6+$7>0) print $0}} }' | grep -B 1 -e "Up" -e "Down"
And this $CMDFILE contains
show ip address
show switch stack-ports
exit
The first command is so I have an IP address I can find with grep; the
second command shows stack errors.
Those are my SecureStack telnet scripts (so far).
