DHCP_SNOOPING Messages
Error Message DHCP_SNOOPING-4-DHCP_SNOOPING_PVLAN_WARNING: DHCP Snooping
configuration may not take effect on secondary vlan [dec]. [chars]
Explanation This message means that if the private VLAN feature is configured, the DHCP snooping
configuration on the primary VLAN automatically propagates to all the secondary VLANs. [dec] is
the VLAN ID of the secondary VLAN, and [chars] is the warning.
Recommended Action No action is required.
Error Message DHCP_SNOOPING-4-IP_SOURCE_BINDING_NON_EXISTING_VLAN_WARNING: IP
source binding is configured on non existing vlan [dec].
Explanation This message means that an IP source binding was configured on a VLAN that has not
been configured yet. [dec] is the VLAN.
Recommended Action No action is required.
Error Message DHCP_SNOOPING-4-IP_SOURCE_BINDING_PVLAN_WARNING: IP source filter may
not take effect on secondary vlan [dec] where IP source binding is configured.
[chars].
Explanation This message means that if private VLANs are configured, the IP-source-guard filter on the
primary VLAN automatically propagates to all secondary VLANs. [dec] is the secondary VLAN, and
[chars] is the warning.
Recommended Action No action is required.
Error Message DHCP_SNOOPING-4-NTP_NOT_RUNNING: NTP is not running; reloaded binding
lease expiration times are incorrect.
Explanation This message means that if the DHCP snooping database agent loads the DHCP
snooping bindings and Network Time Protocol (NTP) is not running, the calculated lease duration
for the bindings is incorrect.
Recommended Action Configure NTP on the switch to provide an accurate time and date for the
system clock. Then disable and re-enable DHCP snooping to clear the DHCP snooping binding
database.
Error Message DHCP_SNOOPING-4-QUEUE_FULL: Fail to enqueue DHCP packet into
processing queue: [chars], the queue is most likely full and the packet will be
dropped.
Explanation This message means that the CPU is receiving DHCP at a higher rate than the DHCP
snooping can process. These DHCP packets are dropped to prevent a denial of service attack. [chars]
is the warning.
Recommended Action No action is required.
