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

2c2dcbd3

TYPE DHCP-SNOOPING

VERSION 1

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.
