Specifying the Packet Types to Which the User-Level Rate Limiting Applies

Specifying the Packet Types to Which the User-Level Rate Limiting Applies

Context

By default, the switch limits the rates of the ARP, ND, DHCP Request, DHCPv6 Request, and 8021x packets received from user MAC addresses, and discards excessive packets when the packet rates exceed the rate limit. If you need to limit the rate of only IGMP and HTTPS-SYN packets or packets of the specified types, specify the packet type.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run cpu-defend host-car enable

    The user-level rate limiting is enabled.

    By default, the user-level rate limiting is enabled.

  3. Run cpu-defend host-car { { arp | dhcp-request | dhcpv6-request | igmp | nd | 8021x | https-syn } * | all }

    The packet types to which the user-level rate limiting applies is specified.

    By default, the user-level rate limiting can apply to ARP Request, ARP Reply, ND, DHCP Request, DHCPv6 Request, and 8021x packets, but does not apply to IGMP and HTTPS-SYN packets.
