show forwarding configuration
Description
Displays the configured selection criteria for ECMP (Equal Cost Multi Paths) routes and load-sharing group ports and the hardware table settings, including the configured and current hash algorithm and dual-hash settings.
Syntax Description
This command has no arguments or variables.
Default
N/A.
Usage Guidelines
- 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 Layer4 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.‘
- Fabric flow control—Whether flow control fabric configuration is set to ‘auto‘ or ‘off.‘
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:
