Configuring the T1 Frame Checksum

By default, T1 interfaces use a 16-bit frame checksum. You can configure a 32-bit checksum, which provides more reliable packet verification. However, some older equipment might not support 32-bit checksums.

To configure a 32-bit checksum, include the fcs 32 statement at the [edit interfaces interface-name t1-options] hierarchy level:



[edit interfaces interface-name t1-options]

fcs 32;

To return to the default 16-bit frame checksum, delete the fcs 32 statement from the configuration:



[edit]
user@host# delete interfaces t1-fpc/pic/port t1-options fcs 32

To explicitly configure a 16-bit checksum, include the fcs 16 statement at the [edit interfaces interface-name t1-options] hierarchy level:



[edit interfaces interface-name t1-options]

fcs 16;
