Different between loopback local line and payload?

[muhammad shahrir osman]

Hello,

I’m having difficulty to understand the different between loopback local line and loopback local payload?

What is the different between these two? Is there any different when troubleshooting using either of these two?

Router(config)#controller e1 1/5

Router(config-controller)#loopback ?

  diag   Local diagnostic loopback

  local  Local loopback [line | payload]

Appreciate and thanks in advance for any help

Regards,

Line loopback transmits the received bitstream as it is.

Payload generates framing as interface normally does, and only retransmits the data portion in T1/E1.
