Hello guys,
Another
problem happens and it looks wired. I can test the snmpget -i + <arg> to
cisco2 from boss after I re-matched the ip address of boss and experiment
switch : ) But in the experiment, it fails with such error message:
*** WARNING: snmpit:
*** SNMP SET failed - In /usr/testbed/bin/snmpit
*** SNMPIT set failed for device cisco2 (try 10 of 10)
*** Variable was [portDuplex,0.5,2,INTEGER]
*** Returned (undefined), ErrorNum was 6
*** Error string is: noAccess
I
believe boss is sending package through 192.168.1.70(boss) to 192.168.1.1(experiment
switch). And during the experiment, I get the vlan set up from boss terminal,
however, after the experiment fails, those setup was cleaned up.
%wap
snmpit -l
VLAN
Project/Experiment VName Members

testbed/test11 link0-del pc2:1 pc3:1
My
ns script is quite simple because there are only 3 free nodes for testing:
set
link0 [$ns duplex-link $nodeB $nodeA 30Mb 50ms DropTail]
tb-set-link-loss
$link0 0.01
I
am stuck here as my knowledge is limited. Does anyone has an idea about this
problem?
Best

When I check the "show running config", I can find the
set community

as follows:

I'm a little confused here; in an earlier email, you said that
cisco2 was pingable from your boss, but I'm wondering how that
can be since there does not appear to be any way for boss to send
packets to vlan 2 (the ip default-gateway is not reachable from it).

ip http secure-server

************************************
But I didn't see any error message like "C388 Unknown
community name".
It was not an error message, it was the second or third line down
in the output of the "Show snmp" command.
Meanwhile, as you mentioned, I can try snmpit -v 1 <other
args> on both
switch. It looks fine on control switch, but still time out on the
experiment switch, with the same community string in the database.
Here
is
the output:

Well, at least it appears that your database is appropriately
configure for both switches ... ;-)
