Configuring the Policy for Sending and Receiving Host Packets

Configuring the Policy for Sending and Receiving Host Packets

You can configure the policy for sending and receiving host packets to control the selection of tunnels and the forwarding mode for transmitting host packets.

Usage Scenario

By default, when a device is configured with multiple TE tunnels with various priorities, the device randomly selects a TE tunnel in load balancing mode to send host packets. To configure the device to send host packets over the TE tunnel with the highest priority, run the host-packet send service-class te enable command.

If a sub-interface on the local device has been configured with a VLAN priority for host packets using the 8021p 8021p-value command, a sub-interface on the peer device has been configured with the same VLAN priority and a VLAN ID using the dot1q termination vid low-pe-vid 8021p { 8021p-value1 [ to 8021p-value2 ] } &<1-8> command, and the IP addresses of the two sub-interfaces are on the same network segment, the local and peer devices fail to communicate with each other and the BGP peer relationship fails to be established between the local and peer devices. To disable fast reply of host packets based on the service type configured on the interface, run the host-packet fast-reply disable command.

A device proactively sends a large number of host packets during interface route switching. To relieve the CPU usage of the host module, run the host-packet fast-send enable command to enable fast reply of host packets based on the service type configured on the interface.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run host-packet send service-class te enable

    The device is configured to send host packets over a TE tunnel with the highest priority.

  3. Run host-packet fast-reply { tcp | udp | rawip } disable

    Fast reply of host packets is disabled.

  4. Run host-packet fast-send { tcp | udp | rawip } enable

    Fast reply of host packets is enabled.
