process, the SRPU can judge whether each service card in the device operates
normally.
You can also set the maximum number of times the SRPU fails to receive handshake
packets. If the number of times the SRPU fails to receive handshake packets exceeds
the upper limit, the switch resets the processing chip automatically. When the SRPU
receives handshake packets, it resets the counter automatically.
You can also set whether to restart the service card or the switch when the number of
times the SRPU fails to receive handshake packets exceeds the upper limit.

An internal channel refers to the interface channel between the SRPU and the service
cards. The SRPU sends handshake packets to each service card every second. After
receiving the handshake packets, the service cards reports the result to the SRPU. In
this case, the SRPU knows that the service cards are operating normally. Through this
process, the SRPU can judge whether each service card in the device operates
normally.
