It has IP to mac address translation entries based upon DHCP conversations on the vlan.


 


You can use the command:


ip dhcp snooping database tftp://x.x.x.x/dhcpbinding.txt to store this database somewhere.


 


It should be readable like a text file. If you store it on flash here is a way to view it, mine has no bindings unfortunately:


Switch-E1#more flash:dhcp.txt

TYPE DHCP-SNOOPING

You can view the bindings with:


 


show ip dhcp snooping binding


 


You can also see more specific bindings like:


 


show ip dhcp snooping binding vlan 100 (show all bindings related to vlan 100)


show ip dhcp snooping binding interface x/y


show ip dhcp snooping binding 10.10.10.10


 


etc.
