Got a strange problem, maybe some of you could help.
Dhcp snooping is up and running, database are saved to tftp file, all looks good. Snooping running on one vlan,
switch#show ip dhcp snoo
Switch DHCP snooping is enabled
Switch DHCP gleaning is disabled
DHCP snooping is configured on following VLANs:

But, when trying to read binding database from file I got this error:
May 2 11:37:23.681: two gig ethernet port
May 2 11:37:23.681: DHCP_SNOOPING: number not found where expected in interface name
May 2 11:37:23.681: Token for interface not valid.
Im expeting to see either new binding entries or binding collisions. The file are populated with entries that the switch made itself.
I really not sure how to interpret the debug messages, do any of you have any tips?
