Release Information

Statement introduced in JUNOS Release 8.2.


This statement is used only in conjunction with J4350 and J6350 Services Routers that support voice over IP with the TGM550 media gateway module. For Fast Ethernet and Gigabit Ethernet interfaces, ISDN BRI interfaces, and serial interfaces with PPP or Frame Relay encapsulation, configure the dynamic call admission control (dynamic CAC) activation priority value.


priority—The activation priority at which the interface is used for providing call bandwidth. The interface with the highest activation priority value is the primary link for providing call bandwidth. If the primary link becomes unavailable, the TGM550 switches over to the next active interface with the highest activation priority value, and so on.

Range: 0 through 255
Default: 50
