What would cause discovery on Cisco FM to time out

Yes, there many more ports with FM than DM.   The required ports are listed in FM Guide and in the EMC Knowledgebase.

Thank you.

sorry is this is a stupid question but how do you telent on a port other then 23

No problem

telnet ipaddresshere 161

Try to telnet to the ip address on port 161 ..SNMP runs on that port. You will get a blank screen but as long as it does not time out you have connectivity.

Ok great.   i will start there with troubleshooting.

Thanks for the help

Ok  i will try that.  i currently dont have physical access to the switch.  So Device manager and Fabric Manager use different ports?

Hello,

The most common problem that causes this is a firewall or router with IP filtering turned on blocking specific ports that FM uses.   The easiest way to confirm this is to directly connect a laptop to the switch without going through the network (cross over cable, etc.), make sure no firewall software running on the laptop, and see if FM will connect.   If it does something on the network is causing it, usually a firewall.

Thank you.

Something is blocking snmp port. I can telnet to port 161 on my 9134 with no issues.

Can you connect to it using device manager ?

ah  i was close  i tried telnet ip_address:161...

Anyway,  it just sits at connecting...

yes i can and i got the model wrong.  it is a 9216 if that matters

I have FM running on my laptop also
