Cisco Broadband Cable Command Reference Guide
Chapter 2 Cisco Cable Modem Termination System Commands
T1 specifies the amount of time that an authorization for a gate can remain valid. It begins counting
when the CMTS creates a gate with a Gate-Set command and puts the gate in the Authorized state.
The timer stops when the gate is put into the committed state. If the timer expires without the gate
being committed, the CMTS must close the gate and release all associated resources.
T2 specifies the amount of time that a gate can remain in a transient state during gate coordination,
in the event that any gate coordination messages are lost. The timer starts when the CMTS receives
a Dynamic Service Change (DSC) or a Gate-Open message. The timer stops when the CMTS
receives a DSC and a Gate-Open-Ack for the gate. If the timer expires while the gate is still in a
transient state, the CMTS must close the gate and release all associated resources.
Note The T1 and T2 timers can also be specified as part of the gate creation procedure. If a gate
specifies its own values for these timers, the gate’s timers are used instead of the values
specified by this command.
T5 specifies the amount of time that a Gate-Open or Gate-Close message can remain
unacknowledged, and is designed to ensure the retransmission of such messages if they are lost by
the network. The timer starts with the CMTS receives a Gate-Open or Gate-Close message. The
timer stops when the CMTS receives the corresponding Gate-Open-Ack or Gate-Close-Ack. If the
timer expires without the CMTS receiving the proper acknowledgement, the CMTS resends the
Gate-Open or Gate-close message. The T5 continues resending the messages until either the
message is acknowledged or until the T2 timer for the gate has expired.
Note The new timer values apply to all gates that are created after giving the command. Existing gates are not
affected.
Examples The following example shows the T0 timer being set to 20 seconds (20,000 milliseconds):
Router# configure terminal
Router(config)# packetcable timer T0 20000
