DHCP Snooping
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>.

p-address> leased

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>.
