icmp timestamp
Enables or disables ICMP timestamp messages, and sets the minimum packet gap. The minimum packet
gap is the number of microseconds that must pass between ICMP messages of the same type.
icmp timestamp [request | reply] {{enable | disable} | min-pkt-gap gap}
Syntax Definitions
request Specifies timestamp request messages.
reply Specifies timestamp reply messages.
enable Enables the specified ICMP message.
disable Disables the specified ICMP message.
gap The number of microseconds required between ICMP messages of this
type.

Usage Guidelines
• The data received (a timestamp) in the message is returned in the reply together with an additional
timestamp. The timestamp is 32 bits of milliseconds since midnight UT. The Originate timestamp is the
time the sender last touched the message before sending it, the Receive timestamp is the time the
echoer first touched it on receipt, and the Transmit timestamp is the time the echoer last touched the
message on sending it.
• Using this command without specifying a request or reply will enable, disable, or set the minimum
packet gap for both types.
• The timestamp ICMP messages can also be enabled, disabled, and modified using the icmp type
command. See the icmp type command information on the type and code for the timestamp ICMP
messages.
