Re: [Testbed-admins] need advice regarding "SNMP GET failed"

["Cheng Cui" <ccui1@tigers.lsu.edu>]

Sorry, my bad. We didn't notice that gateway problem for Boss's third ip.
Our Boss has two 192.168.0.70 and 192.168.1.70. That's why I can ping
Experiment switch but cannot receive snmp feedback. It's a shame to have
this problem, but thanks very much you guys that helped us so much. ;-)

Best Regards,

    When I check the "show running config", I can find the set community
string,
    as follows:

    ************************************
    cisco2#show running-config

>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> Note This <<<<<<<<<<<<<<<<<<

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 classless
    ip http server
    ip http secure-server
    !
    !
    access-list 1 permit 192.168.0.70
    access-list 2 permit 192.168.0.70
    no cdp run
    snmp-server community vlan2 RW 1
    snmp-server community cisco2 RW 2
    ...
    ************************************

    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 ... ;-)
