25.5 DHCP Snooping Configure

Use this screen to enable DHCP snooping on the Switch (not on specific VLAN), specify the VLAN
where the default DHCP server is located, and configure the DHCP snooping database. The DHCP
snooping database stores the current bindings on a secure, external TFTP server so that they are

Parse failures

This field displays the number of bindings the Switch ignored because the Switch
was unable to understand the binding in the DHCP binding database.

Expired leases

This field displays the number of bindings the Switch ignored because the lease
time had already expired.

Unsupported vlans

This field displays the number of bindings the Switch ignored because the VLAN ID
does not exist anymore.

Last ignored time

This field displays the last time the Switch ignored any bindings for any reason
from the DHCP binding database.

Total ignored bindings
counters

This section displays the reasons the Switch has ignored bindings any time it read
bindings from the DHCP binding database. You can clear these counters by
restarting the Switch or using CLI commands. See the CLI Reference Guide.

Binding collisions

This field displays the number of bindings the Switch has ignored because the
Switch already had a binding with the same MAC address and VLAN ID.

Invalid interfaces

This field displays the number of bindings the Switch has ignored because the port
number was a trusted interface or does not exist anymore.

Parse failures

This field displays the number of bindings the Switch has ignored because the
Switch was unable to understand the binding in the DHCP binding database.

Expired leases

This field displays the number of bindings the Switch has ignored because the lease
time had already expired.

Unsupported vlans

This field displays the number of bindings the Switch has ignored because the VLAN
ID does not exist anymore.
