Configuring the Large Layer 3 Interface Mode

Configuring the Large Layer 3 Interface Mode

Context

By default, a maximum of 8,000 Layer 3 interfaces can be created on a switch. After the assign forward layer-3 interface mode command is executed to enable the large Layer 3 interface mode, you can increase the maximum number of Layer 3 interfaces to 320,000. However, if the ARP resource mode is extended mode, a maximum of 8,000 Layer 3 interfaces can be created.

Layer 3 interfaces share chip resources with Layer 2 VLANs and bridge domains (BDs), so Layer 3 interfaces include VLANs, BDs, main interfaces, Layer 3 sub-interfaces, and tunnel interfaces. Layer 2 VLANs and BDs will occupy chip resources once being created, even if no VLANIF or VBDIF Layer 3 interfaces are created.

NOTE:

Only the CE6870EI and CE6875EI support this function.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run assign forward layer-3 interface mode

    The large Layer 3 interface mode is configured.

    By default, the large Layer 3 interface mode is not configured.

    NOTE:

    The assign forward layer-3 interface mode command takes effect after the switch is restarted.

  3. Run commit

    The configuration is committed.
