Ceasing untrusted relay information logs for <duration>. More than
one DHCP client packet received on an untrusted port with a relay information

detected on port <port-number>. Indicates that a client packet source
MAC address does not match the "chaddr" field. This event is recognized when

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>.

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>.
