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.

# Set the upper limit to 50.

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.
