Atm Pvc Command; Configuring Ppp And Pppoe Dynamic Interfaces Over Static Atm - Juniper JUNOSE SOFTWARE 11.0.X - LINK LAYER CONFIGURATION GUIDE 4-1-2010 Configuration Manual

JUNOSe 11.0.x Link Layer Configuration Guide
NOTE: When the calculated lockout time is equal to or exceeds the maximum lockout
time, the router uses the maximum lockout time value until the time to the next
event exceeds the greater of 15 minutes or the maximum lockout time value. At that
point, the lockout time reverts to the minimum lockout time value.

atm pvc Command

You use the atm pvc command to define the underlying circuit supporting an
ATM 1483 subinterface. When you define a circuit with this command by using the
aal5autoconfig option, it causes the ATM 1483 encapsulation (LLC/SNAP
encapsulation or VC multiplexed) to be autodetected. Alternatively, if you use the
aal5snap or aal5mux ip option, the ATM 1483 encapsulation becomes fixed, but
higher layers can be dynamic.
For example, the following command configures a circuit for autodetection of the
ATM 1483 encapsulation and all higher layers.
You can also include the atm pvc command in a base profile assigned to a dynamic
ATM 1483 interface to apply encapsulation and traffic-shaping parameters to a
bulk-configured range of PVCs. For information, see "Configuring Dynamic Interfaces
Using Bulk Configuration" on page 573.

Configuring PPP and PPPoE Dynamic Interfaces over Static ATM

E Series routers support dynamic PPP and PPPoE interfaces. The configuration
procedure is very similar for each.
When using the auto-configure command, select only ppp or pppoe. The router
automatically builds the necessary interfaces for you. When you indicate pppoe, on
receipt of a PPPoE packet, the dynamic interface built is IP over PPP over PPPoE
over ATM. Likewise, when you indicate ppp, the dynamic interface built is IP over
PPP over ATM.
Figure 41 on page 479 shows dynamic PPP interface columns on ATM interfaces.

Configuring PPP and PPPoE Dynamic Interfaces over Static ATM
A short-cycle event is a dynamic interface that is created and torn down within
60 seconds. The router tracks the time between short-cycle events to determine
whether to increase the lockout time for a subsequent short-cycle event.
The minimum lockout time value cannot exceed the maximum lockout time
value. When the minimum and maximum values are equal, the encapsulation
type lockout time becomes fixed.
