Example of show ip source-lockdown bindings Command Output
In the
show ip source-lockdown bindings
command output, the “Not in HW” column specifies whether
or not (YES or NO) a statically configured IP-to-MAC and VLAN binding on a specified port has been
combined in the lease database maintained by the DHCP Snooping feature.
Debugging Dynamic IP Lockdown
To enable the debugging of packets dropped by dynamic IP lockdown, enter the
debug dynamic-ip-
lockdown
command.
To send command output to the active CLI session, enter the
debug destination session
command.
Counters for denied packets are displayed in the
debug dynamic-ip-lockdown
command output. Packet
counts are updated every five minutes. An example of the command output is shown in
Figure 22
.
When dynamic IP lockdown drops IP packets in VLAN traffic that do not contain a known source IP-
to-MAC address binding for the port on which the packets are received, a message is entered in the
event log.
