Using UCMB 10.11 CUP2 CP 14.03.230
I have enabled the following discovery jobs with success:
Range IPs by ICMP
Host Connection by SNMP
Host Networking by SNMP
VLANs by SNMP
VLAN ports by SNMP
But when I run the job "Layer2 Topology VLAN-based by SNMP", it indicates several thousand triggered CIs, but each one times out. I disable the job after about 45 minutes since nothing is working.
All of our switches are Cisco Catalyst with VLANs. I've tried to enable the job "Layer2 Topology Bridge-based by SNMP", but it never shows any triggered CIs. And since we use VLANs, I suspect that it shouldn't run.
Using an SNMP query tool, I've verified that I can query my Cisco switches using the special community string format <COMMUNITY>@<VLAN NUMBER>. I believe this is what the disocvery job should be doing as this is mentioned in the Discovery and Integration Content Guide.
Any ideas on what I am missing which causes the "Layer2 Topology VLAN-based by SNMP" job to timeout?
