- Ceasing untrusted server logs for %s.
More than one packet was received from a DHCP server on an untrusted port. To avoid filling the log file with repeated attempts, untrusted server drop packet events will not be logged for the specified <duration>.
- Client packet destined to untrusted port <port-number> dropped.
Indicates that the destination of a DHCP client unicast packet is on an untrusted port. This event is recognized when a client unicast packet is dropped because the destination address is out a port configured as untrusted.
- Ceasing untrusted port destination logs for %s.
More that one client unicast packet with an untrusted port destination was dropped. To avoid filling the log file with repeated attempts, untrusted port destination attempts will not be logged for the specified <duration>.
- Unauthorized server <ip-address> detected on port <port-number>.
Indicates that an unauthorized DHCP server is attempting to send packets. This event is recognized when a server packet is dropped because there are configured authorized servers and a server packet is received from a server that is not configured as an authorized server.
- Ceasing unauthorized server logs for <duration>.

Indicates the reception on an untrusted port of a client packet containing a relay information option field. This event is recognized when a client packet containing a relay information option field is dropped because it was received on a port configured as untrusted.
- Ceasing untrusted relay information logs for <duration>.
More than one DHCP client packet received on an untrusted port with a relay information field was dropped. To avoid filling the log file with repeated attempts, untrusted relay information packets will not be logged for the specified <duration>.
- Client address <mac-address> not equal to source MAC <mac-address> detected on port <port-number>.
Indicates that a client packet source MAC address does not match the “chaddr” field. This event is recognized when the dhcp-snooping agent is enabled to filter DHCP client packets that do not have a matching “chaddr” field and source MAC address.
- Ceasing MAC mismatch logs for <duration>.
More than one DHCP client packet with a mismatched source MAC and chaddr field was dropped. To avoid filling the log file with repeated attempts, client address mismatch events will not be logged for the specified <duration>.
- Attempt to release address <ip-address> leased to port <port-number> detected on port <port-number> dropped.
Indicates an attempt by a client to release an address when a DHCPRELEASE or DHCPDECLINE packet is received on a port different from the port the address was leased to.
- Ceasing bad release logs for %s.
More than one bad DHCP client release packet was dropped. To avoid filling the log file with repeated bad release dropped packets, bad releases will not be logged for <duration>.
