You get the message, “Cannot connect to session” when you
try to start a Cisco MGC Node Manager session. Make sure that Cisco EMF is running.
•If Cisco EMF is not running, start it; then retry starting
Cisco MGC Node Manager.
•If Cisco EMF is running, check to see if the IP address or
host name of the Cisco MGC Node Manager server has
changed since Cisco MGC Node Manager was ins tal led .
If so, follow the steps described for the next problem.
You get the message, “System IP address does not match
databased address” when you try to start Cisco EMF. This may be caused by a change in the IP address or host
name of the Cisco MGC Node Manager server after Cisco
MGC Node Manager was installed. To correct the problem:
1. Stop Cisco EMF:
/opt/cemf/bin/cemf stop
2. If needed, update the IP address in Cisco EMF:
/opt/cemf/bin/cemf updateIP -m
You are prompted for the new IP address. Enter the new
IP address.
3. If needed, update the host name in Cis co EMF :
/opt/cemf/bin/cemf updateName -m
You are prompted for the new host name. Enter the new
name.
4. Restart Cisco EMF.
/opt/cemf/bin/cemf start
Note If the Management server address or name has
changed in a distributed configuration, make the
necessary changes on both the Management server
and the Presentation server. If the Presentation server
address or name has changed, make the changes on
the Presentation server only.
