Device Type UNKNOWN

Unanswered Question
Jan 29th, 2009

Hi All,

I'm am having a bit of trouble getting 2 recently added switches into LMS (one a 6509 and the other a 4500). They appear in data collections but it show device type unkown. Running a verification report results in device not reachable, though I can telnet to it from device center.. I'd appreciate it if anyone could offer some advice.


I have this problem too.

The telnet from Device Center is not an adequate test of reachability. That telnet occurs from the client, not the server. A better test is the Device Center's Management Station to Device. Test the SNMP read-only access. You can also try using the SNMP Walk tool with a starting OID of sysObjectID.

These symptoms sound like the devices are not SNMP reachable from the server.
