Hi xcatters,
I am currently working with switch discovery of compute nodes connected to
a Cisco 3750 switch.
I had originally only configured the ports on the switch that actually had
something plugged into them and then tried to do a discovery. The attached
file is the configuration of the ports that i started with
Watching the messages log i found the following message
Sep 7 18:31:58 mgt xcat[80098]: Error communicating with
ms-h25-mgtobm-1g-40: Unable to get MAC entries via either BRIDGE or Q-BRIDE
MIB
After 3 days of frustration and going round and round in circles i found
that if i set
switchport access vlan 415
on port 1/0/43 all of a sudden the discovery starts working.
I have no idea why and can't explain this. If anyone could shed some light
on what is special about port 43 or the configuration of it i would be most
appreciative.
Thanks for your help in advance
