1. Re: macsuck skipping vlans with devices in use
(Christian Ramseyer)
--- Begin Message ---
Hi
snmp-info exposes per vlan interface information like i_vlan and
i_vlan_membership. You can run netdisco-do macsuck -DIS -d <ip> to see
what is called and returned.
There is a config option
https://github.com/netdisco/netdisco/wiki/Configuration#macsuck_all_vlans
macsuck_all_vlans
Value: Boolean. Default: false.
Set to macsuck all VLANs, not just the ones that are being used on
ports. This is a debug option. Set this if you think that the option of
not macsucking VLANs that aren’t in use on device ports is somehow
interfering.
I'm not sure how bad or slow globally enabling this would be and if it
solves your problem. Worth a try, or to make a targeted fix you maybe
can figure out where snmp-info goes wrong and patch it for the device
class in question.
Cheers
Christian

I did a debug run of netdisco-do macsuck and found the message “not in
use by any port - skipping" on several vlans that do have devices. How
does it determine which vlans are in use? Can I override it? I have a
feeling that the mechanism isn’t taking into account the dynamic vlan
assignments we have on our Cisco switches.
Thanks,
Joseph B.
