H3C S7500 Series Ethernet Switches
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.
S7500 Ethernet switches support this feature. Through this feature, you can monitor
internal channels.
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.

1.3.2 Monitoring Internal Channel Configuration

Follow these steps to monitor internal channels:
Enter system view
Enable the function of
monitoring internal
channels
Configure to restart the
service card
Configure to restart the
switch
Set the upper limit for
resetting the chip

1.4 Configuring Switch Chip Auto-Reset

1.4.1 Introduction

In actual application, a switch may fail to process services normally due to internal
channel block or because the switch chip is busy.
The S7500 series switches 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 card and the backplane fails, the switch resets the
switch chip automatically to resume the corresponding card.
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.
