Configuring a Hash Mode of the VLAN-XLATE Table

Configuring a Hash Mode of the VLAN-XLATE Table

When a hash conflict in the VLAN-XLATE table occurs, run the assign forward vlan-xlate command to change the uplink and downlink hash modes of the VLAN-XLATE table to reduce hash conflicts.

Context

NOTE:
  • After a hash mode of the VLAN-XLATE table is configured, you must restart the device to make the configuration take effect.

  • Only the CE6850HI, CE6851HI, CE6855HI, CE6856HI, CE6850U-HI, CE6855HI, CE6860EI, CE7800 series, and CE8800 series switches support this function.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run assign forward vlan-xlate { egress | ingress } hash { crc16-lower | crc16-upper | crc32-lower | crc32-upper | lsb }

    A hash mode of the VLAN-XLATE table is configured.

    By default, the uplink and downlink hash modes of the VLAN-XLATE table are both crc32-lower.

  3. Run commit

    The configuration is committed.

Verifying the Configuration

Run the display forward vlan-xlate hash mode command in all views to check the uplink and downlink hash modes of the VLAN-XLATE table.
