Introduction
An internal channel refers to the interface channel between the Fabric and the
service modules. The Fabric sends handshake packets to each service module every
second. After receiving the handshake packets, the service modules reports the
result to the Fabric. In this case, the Fabric knows that the service modules are
operating normally. Through this process, the Fabric can judge whether each
service module in the device operates normally.
Switch 7750s support this feature. Through this feature, you can monitor internal
channels.
You can also set the maximum number of times the Fabric fails to receive
handshake packets. If the number of times the Fabric fails to receive handshake
packets exceeds the upper limit, the switch resets the processing chip
automatically. When the Fabric receives handshake packets, it resets the counter
automatically.
You can also set whether to restart the service module or the switch when the
number of times the Fabric fails to receive handshake packets exceeds the upper
limit.

Configure to restart the service card
Configure to restart the switch
Set the upper limit for resetting the
chip
In actual application, a switch may fail to process services normally due to internal
channel block or because the switch chip is busy.
Switch 7750s support the function of resetting switch chips automatically. In case
that the function of monitoring internal channels is enabled, when the internal
channel handshake between a module and the backplane fails, the switch resets
the switch chip automatically to resume the corresponding module.
When the function of resetting switch chips is disabled, even if the switch finds
that the internal channel handshake fails, it cannot reset the switch chip
automatically.
