NETGEAR 8800 Chassis Switch CLI Manual Syntax Description This command has no arguments or variables. Default N/A. Usage Guidelines The output of this command displays the following information: • Configured hash algorithm-The hash algorithm configured on the switch. After the configuration is saved and the switch is rebooted, the switch uses this hash algorithm. • Current hash algorithm-The hash algorithm currently used by the switch. • Configured dual-hash setting-Whether the dual-hash feature is configured 'on' or 'off' on the switch. After the configuration is saved and the switch is rebooted, the switch uses this setting. • Current dual-hash setting-Whether the dual-hash feature is currently 'on' or 'off' on the switch. • Dual-Hash recursion level-The current dual-hash recursion level; default is '1.' • Sharing criteria-Current selection criterion used for ECMP route sharing as well as for load-sharing groups. Specifies which Layer 3 and Layer 4 information is used in the sharing hash algorithm. For more information, see the description for the configure forwarding sharing [L3 | L3_L4] command. • Group Table Compression-Whether the group table compression is currently 'on' or 'off' on the switch. • Switching mode-Whether the switching mode is currently set to 'cut-through' or 'store-and-forward.' It is possible for the values of the configured and the current hash, or the configured and current dual-hash settings to be different. For example, if you modified the hash algorithm and have not saved the configuration and rebooted the switch, the values might be different. In this situation, the switch also displays the following message: NOTE: A save and reboot are required before the configured hash will take effect Example The following command displays the hardware forwarding algorithm configured on the switch: show forwarding configuration The following is sample output from this command on a NETGEAR 8800 series switch: BD-8810.43 # show forwarding configuration L2 and L3 Forwarding table hash algorithm: Configured hash algorithm: Current hash algorithm: crc32 crc32 1358 | Appendix B.

Troubleshooting Commands

NETGEAR 8800 Chassis Switch CLI Manual

Syntax Description

This command has no arguments or variables.

Default

N/A.

Usage Guidelines

The output of this command displays the following information:

•

Configured hash algorithm

—The hash algorithm configured on the switch. After the

configuration is saved and the switch is rebooted, the switch uses this hash algorithm.

•

Current hash algorithm

—The hash algorithm currently used by the switch.

•

Configured dual-hash setting

—Whether the dual-hash feature is configured ‘on’ or ‘off’

on the switch. After the configuration is saved and the switch is rebooted, the switch uses

this setting.

•

Current dual-hash setting

—Whether the dual-hash feature is currently ‘on’ or ‘off’ on

the switch.

•

Dual-Hash recursion level

—The current dual-hash recursion level; default is ‘1.’

•

Sharing criteria

—Current selection criterion used for ECMP route sharing as well as for

load-sharing groups. Specifies which Layer 3 and Layer 4 information is used in the

sharing hash algorithm. For more information, see the description for the

configure

forwarding sharing [L3 | L3_L4]

command.

•

Group Table Compression

—Whether the group table compression is currently ‘on’ or ‘off’

on the switch.

•

Switching mode

—Whether the switching mode is currently set to ‘cut-through’ or

‘store-and-forward.’

It is possible for the values of the configured and the current hash, or the configured and

current dual-hash settings to be different. For example, if you modified the hash algorithm

and have not saved the configuration and rebooted the switch, the values might be different.

In this situation, the switch also displays the following message:

NOTE: A save and reboot are required before the configured hash will take effect

Example

The following command displays the hardware forwarding algorithm configured on the switch:

show forwarding configuration

The following is sample output from this command on a NETGEAR 8800 series switch:

BD-8810.43 # show forwarding configuration

L2 and L3 Forwarding table hash algorithm:

Configured hash algorithm:

crc32

Current hash algorithm:
