1.1  Configuring Boot ROM Upgrade with App File

By enabling Boot ROM to upgrade together with the app file, you can ensure that the Boot ROM versions of the current SRPU and service cards match the version of the current app file, thus avoiding invalid feature implementation caused by mismatching.

Two upgrade types are available:

l           The current startup file as the upgrade file for Boot ROM

l           The specified App file as the upgrade file for Boot ROM

1.1.1  Boot ROM Upgrade Configuration

Follow these steps to configure Boot ROM upgrade

To do...	Use the command...	Remarks
Set the current startup file as the upgrade file for Boot ROM	boot bootrom default [ slot slot-number-list ]	Optional
Set the specified App file as the upgrade file for Boot ROM	boot bootrom file-url [ slot slot-number-list ]	Optional
Set the primary startup file at next booting and use it to upgrade Boot ROM	boot boot-loader primary file-url	Optional

 

 

1.1.2  Boot ROM Upgrade Configuration Example

I. Network requirements

l           Use the current startup file to upgrade the Boot ROMs of all normal LPU boards in position.

l           Use the specified App file (abcd.app) to upgrade the Boot ROMs of all normal LPU boards in position.

l           Specify the App file abcd.app as the primary startup file for next booting and use it to upgrade the Boot ROMs.

II. Configuration example

# Use the current startup file to upgrade the Boot ROMs of all normal LPU boards in position.

<H3C> boot bootrom default

# Use the specified App file (abcd.app) to upgrade the Boot ROMs of all normal LPU boards in position.

<H3C> boot bootrom abcd.app

# Specify the App file abcd.app as the primary startup file for next booting and use it to upgrade the Boot ROMs.

<H3C> boot boot-loader primary abcd.app

1.2  Configuring Inter-Card Link State Adjustment

1.2.1  Introduction

The inter-card link state adjustment function is designed to improve the adaptability of the inter-card links in an S7500 series switch. It enables you to set the mode in which inter-card links are established as needed.

 

 

Inter-card links can be established in one of the following two modes:

l           Auto-negotiation mode, where inter-card links are established through negotiation to improve the adaptability and stability. This mode is based on the corresponding Ethernet standards. By default, the SRPU and the service cards in an S7500 series Ethernet switch negotiate to establish 1000 Mbps links in between.

l           Fix mode, where 1000 Mbps links are established between the SRPU and the service cards without negotiation. Therefore, the time for negotiation is saved. For the switches operating as network nodes, establishing inter-card links in this mode improves the response speed and reduces the influence on access devices when board switchovers occur.

 

 

1.2.2  Inter-Card Link State Adjustment Configuration

Follow these steps to configure inter-card link state adjustment:

To do...	Use the command...	Remarks
Enter system view	system-view	—
Set the mode in which inter-card links are established	set inlink { auto | fix }	Required By default, inter-card links are established in the auto negotiation mode

 

1.3  Configuring Internal Channel Monitoring

1.3.1  Introduction

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 report 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.

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:

To do...	Use the command...	Remarks
Enter system view	system-view	—
Enable the function of monitoring internal channels	monitor inner-channel	Optional
Configure to restart the service card	monitor inner-channel reboot-lpu	Optional
Configure to restart the switch	monitor inner-channel reboot-switch	Optional
Set the upper limit for resetting the chip	monitor inner-channel upper-limit upper-timers	Optional

 

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.

1.4.2  Switch Chip Auto-reset Configuration

Follow these steps to configure switch chip auto-reset:

To do...	Use the command...	Remarks
Enter system view	system-view	—
Enable the function of monitoring internal channels	monitor inner-channel	Required
Enable switch chip auto-reset	monitor slot slot-id enable	Required By default, switch chips cannot be reset automatically when the internal channel handshake fails
Disable switch chip auto-reset	monitor slot slot-id disable	Optional
