CTP Layer 2 Bridging Overview


CTP layer 2 bridging mode is used to aggregate many serial interfaces into one or several Ethernet interfaces. Each physical serial interface on the CTP chassis maps to a separate Ethernet VLAN interface on the destination router. Aggregation is supported on a port-by-port basis, and other ports on the same node can be used for circuit emulation.

In layer 2 bridging mode, packets are extracted from the line on the serial interface. This is in contrast to circuit emulation mode where every bit on the serial interface is received (regardless of content) and formed into packets

You can use the CTP CLI menu to configure these interfaces. Layer 2 bridging is supported on CTPView release 3.1 and later.
