unknow status after restart

i have a weird problem that is i added about 30 nodes (all cisco switches) in NPM(v 9.1 sp5 slx) and they work fine till i had to shut down the server and start it again (i must to move the server to another place). and when i start server again all the nodes are in UNKNOWN status. and when i added a node in system manager again it start to work.

my config for snmp v3 is :

snmp-server view test iso included
snmp-server group admin v3 auth read test access 50
snmp-server user test admin v3 auth md5 test

anyone have any idea why its happened?

I had the same problem just now. After a restart of the server 4 of my switches (all 2960's) had unknown status on all their ports.

I'm also using snmpv3, and 9.1 SP4 SLX.

Had to re-add the four switches to get them working. A database issue, perhaps?

Same issue running 9.5 SP3. rebooting server and all nodes are respoding to ICMP but the interfaces are showing in an unknown state. I can delete all 400+ nodes and re-add, but if server restarts, they come back in an unknown status. All are Cisco Devices. Also running NCM on same server and it is working perfectly.

Anyone have any idea's -

All services are running and have been restarted, no outstandint polls, CPU 8 x 3.0 Xeon with 12GB Ram. SQL Ent 2005. Database Size 144MB.

Are you also using SNMPv3 as the other two above used? Best bet is to open a support ticket
