# atm mcpt-timers

#### Syntax

atm mcpt-timers timer1 timer2 timer3

no atm mcpt-timers

#### Release Information

Command introduced before JUNOSe Release 7.1.0.

#### Description

Configures systemwide values for the three ATM Martini cell packing timers. These timers define the time threshold that the router uses to collect and concatenate ATM cells in a single VCC cell relay–encapsulated packet and transmit the packet on an MPLS pseudowire connection. When the timer expires, the router forwards the packet even if the number of concatenated ATM cells in the packet is fewer than the specified maximum number of cells per packet. The no version restores the default values for all three timers.

| Note: See the atm cell-packing command for information about specifying the maximum number of concatenated cells per packet and identifying which of the three ATM Martini cell packing timers you want to use to detect timeout of the cell collection threshold.

#### Options

- timer1—Number of microseconds in the range 100–4095; default value is 100
- timer2—Number of microseconds in the range 100–4095; default value is 500
- timer3—Number of microseconds in the range 100–4095; default value is 1000

#### Mode
