4 Release 11.1 CA

Configuration Example

The following example shows a typical configuration for serial interface 1/0/0 on a PA-E3 serial port

adapter in a Cisco 7500 series router. The dsu bandwidth command reduces the bandwidth by

padding the E3 frame, the dsu mode command enables and improves interoperability with other

DSUs, and the national bit command sets Bit 12 in the E3 frame to 1.

router# configure terminal

router(config)# interface serial 1/0/0

router(config-if)# ip address 1.1.1.10 255.255.255.0

router(config-if)# clock source internal

router(config-if)# crc 32

router(config-if)# dsu bandwidth 16000

router(config-if)# dsu mode 0

router(config-if)# national bit 1

router(config-if)# no scramble

router(config-if)# framing g751

router(config-if)# no shutdown

router(config-if)# exit

router(config)# exit
