Parameters
crc4: Sets framing format to CRC4.
no-crc4: Sets framing format to no-CRC4.
Usage guidelines
An E1-F interface in framed mode supports both CRC4 and no-CRC4 framing formats, where CRC4
supports four-bit CRC on physical frames but no-CRC4 does not.
Examples
# Set the framing format of E1-F interface Serial 2/0 to crc4.
<Sysname> system-view
[Sysname] interface serial 2/0
[Sysname-Serial2/0] fe1 frame-format crc4
