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.
Example
# Set the upper limit to 50.

Syntax

monitor slot slot-id disable
View
System view
Parameter
slot-id: Slot ID. The value range depends on the products.
Description
Use the monitor slot enable command to enable switch chip auto-reset.
Use the monitor slot disable command to disable switch chip auto-reset.
By default, switch chips cannot be reset automatically when the internal channel
handshake fails.
In actual application, a switch may fail to process services normally due to internal
channel block or because the switch chip is busy.
The Switch 7750 supports 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.
Example
# Enable switch chip auto-reset for the card in slot 2.
