I have problem with NMS add/contact device [B5 switch]. The device is configured, pingable, telnet/ssh work ok from netsight appliance. Also snmpwalk with netsight credential from NMS appliance [cli] works as it should work.
[eg. snmpwalk -v3 -l authPriv -a SHA -x AES -u Very_secret_user -A secret_password -X secret_password 10.70.16.12
iso.184.108.40.206.220.127.116.11 = STRING: "Enterasys Networks, Inc. B5G124-24P2 Rev 06.71.03.0025"]
The device on NMS Console is shown with '?' mark. Refreshing, rediscovering, deleting and adding again doesnt solve problem. From NMS console I can run Device manager [work ok], execute MiB's - works ok, but still there is 'contact not established' status.
Any sugestions ?
[ps. this devices was previousely present at NMS [ok] and disconnected for some time]
Supplement: When I manualy run Tools->Discover
with device ip address and snmp creds - device was connected ok and now looks ok.
