Configure a 32-Bit Checksum

Action

To explicitly configure the 32-bit checksum, follow these steps:

  1. In configuration mode, go to the following hierarchy level:
  2. [edit]
    
    user@host# edit interfaces so-fpc/pic/port sonet-options
    
    
    
  3. Configure the 32-bit checksum:
  4. [edit interfaces so-fpc/pic/port sonet-options]
    
    user@host# set (fcs 32 | rfc-2615)
    
    
    

    NOTE: The rfc-2615 statement automatically configures the interface to use FCS 32 and changes the C2 byte to 0x16, as per the RFC.

  5. Verify the configuration:
  6. user@host# show
    
    
    

For example:

[edit interfaces so-0/0/0 sonet-options]
user@host# show 
fcs 32;

or


[edit interfaces so-0/0/0 sonet-options]
user@host# show 
rfc-2615;

  1. Commit the configuration:
  2. user@host# commit
    
    
    

    NOTE: On a Channelized OC-12 interface, the sonet-options fcs statement is not supported. To configure FCS on each DS-3 channel, you must include the t3-options fcs statement in the configuration for each channel.
