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 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 The 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 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 If the DHCP snooping database agent loads the DHCP snooping bindings and 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
