Release Information Statement introduced before Junos OS Release 7.4.

Statement introduced in Junos OS Release 12.2 for the ACX Series Universal Access

Routers.

Description For E1/E3, SONET/SDH, and T1/T3 interfaces, configure the frame checksum (FCS) on

the interface. The checksum must be the same on both ends of the interface.

On a channelized OC12 interface, the SONET/SDH fcs statement is not supported. To

configure FCS on each DS3 channel, you must include the t3-options fcs statement in

the configuration for each channel. For SONET/SDH, the channelized OC12 interface

supports DS3 to STS-1 to OC12. For SDH, the channelized OC12 interface supports NxDS3

to NxVC3 to AU3 to STM.

NOTE: When configuring E1 or T1 interfaces on 10-port Channelized E1/T1 IQE

PICs, the fcs statement must be included at the [edit interfaces e1-fpc/pic/port]

or [edit interfaces t1-fpc/pic/port] hierarchy level as appropriate.

Options 16—Use a 16-bit frame checksum on the interface.

32—Use a 32-bit frame checksum on the interface. Using a 32-bit checksum provides

more reliable packet verification, but some older equipment might not support 32-bit

checksums.

Default: 16

Required Privilege

Level

interface—To view this statement in the configuration.

interface-control—To add this statement to the configuration.
