(Optional) Configuring CAR for Whitelisted DHCPv6 Sessions

You can configure an aging time and bandwidth parameters for CAR for whitelisted DHCPv6 sessions to flexibly isolate the sessions.

Context

By default, CAR for whitelisted DHCPv6 sessions is enabled to isolate the sessions. This prevents DHCPv6 packets from different DHCPv6 servers from preempting one another's bandwidth resources. A device generates whitelists based on information in DHCPv6 packets from different DHCPv6 servers. After a whitelist is generated, if the device does not receive packets from the DHCPv6 server to which the whitelist belongs within 30 minutes, it ages out the whitelist. If the default aging time and bandwidth parameters of a whitelist involved in CAR for whitelisted DHCPv6 sessions do not meet service requirements, you can adjust them.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run whitelist session-car dhcpv6 { cir cir-value | cbs cbs-value | pir pir-value | pbs pbs-value } *

    Bandwidth parameters are configured for CAR for whitelisted DHCPv6 sessions.

  3. Run whitelist session-car dhcpv6 aging-time aging-time-value

    An aging time is configured for a whitelist involved in CAR for whitelisted DHCPv6 sessions.

  4. (Optional) Run whitelist session-car dhcpv6 disable

    CAR for whitelisted DHCPv6 sessions is disabled.

  5. Run commit

    The configuration is committed.
