Usage Guidelines
The show ip dhcp snooping binding command output shows the dynamically configured bindings.
If DHCP snooping is enabled and an interface changes to the down state, the switch does not delete the
statically configured bindings.
Expressions are case sensitive. For example, if you enter | exclude output, the lines that contain output

do not appear, but the lines that contain Output appear.
