Feature Limitations

  • In versions earlier than V200R002C50, simplified ACL-based traffic policies do not support IPv6. In V200R002C50 and later versions, simplified ACL-based traffic policies support IPv6.
  • If packets match multiple simplified ACL-based traffic policies, you can run the display traffic-policy apply-information command in the diagnostic view to check the priorities of the simplified ACL-based traffic policies that take effect. The command output displays the traffic policies that take effect in descending order of priority.
  • When an ACL-based simplified traffic policy is configured on a VLANIF interface:
    • In versions earlier than V200R005C00, the device can only define matching rules based on the IPv4 address type, source IPv4 address, destination IPv4 address, protocol type, source port number, destination port number, and IP fragment flag.
    • In V200R005C00 and later versions, the device can only define matching rules based on the IPv4 address type, source IPv4 address, destination IPv4 address, IPv6 address type, source IP address, destination IP address, protocol type, source port number, destination port number, and IP fragment flag.
  • When an ACL-based simplified traffic policy is configured on a VBDIF interface:
    • In versions earlier than V200R002C50, an ACL rule can only match the source IPv4 address, destination IPv4 address, protocol type, source port number, and destination port number.
    • In V200R002C50 and later versions, an ACL rule can only match the source IPv4 address, destination IPv4 address, source IPv6 address, destination IPv6 address, protocol type, source port number, and destination port number.
  • When an ACL-based simplified traffic policy is configured for a QoS group:
    • In versions earlier than V200R005C00, an ACL-based simplified traffic policy can be configured only for the inbound direction of a QoS group.

      In V200R005C00, an ACL-based simplified traffic policy can be configured for the outbound direction of a QoS group containing Ethernet or Eth-Trunk member interfaces only on the CE12800.

      In V200R005C10 and later versions, an ACL-based simplified traffic policy can be configured for the outbound direction of a QoS group containing Ethernet or Eth-Trunk member interfaces on all device models.

    • In versions earlier than V200R003C00, the ACL rule can only match the source IPv4 address, destination IPv4 address, protocol type, source port number, and destination port number.

      In V200R003C00, the ACL rule can only match the source MAC address, destination MAC address, Ethernet type, source IPv4 address, destination IPv4 address, protocol type, source port number, and destination port number.

      In V200R005C00 and later versions, the ACL rule can match the source MAC address, destination MAC address, Ethernet type, source IPv4 address, destination IPv4 address, source IPv6 address, destination IPv6 address, protocol type, source port number, and destination port number.

    • A traffic behavior can define only packet filtering and traffic statistics collection if an ACL-based simplified traffic policy is configured for the outbound direction on the CE12800.

      A traffic behavior can define only packet filtering if an ACL-based simplified traffic policy is configured for the outbound direction on the CE12800E.

    • For the CE12800E, applying an ACL-based simplified traffic policy to a QoS group in the outbound direction is mutually exclusive with the following functions:
      • Adding Eth-Trunk interfaces to an FCoE interface and enabling the traffic statistics collection function in the FCoE interface
      • Applying a traffic policy in the outbound direction of an Eth-Trunk interface
      • Configuring an ACL-based simplified traffic policy in the outbound direction of an Eth-Trunk interface
      • Configuring the traffic statistics collection function on a Layer 3 sub-interface in an Eth-Trunk
  • In V200R001C00 and later versions, the ACL-based traffic statistics collection function can be configured on a Layer 2 sub-interface.

    When an ACL-based simplified traffic policy is configured on a Layer 2 sub-interface, the policy can be applied only in the inbound direction on the CE12800. For the CE12800E equipped with FD-X series cards, the policy can be applied in both inbound and outbound directions. In versions earlier than V200R002C50, the bound traffic classifier can match only the destination MAC address, source MAC address, Ethernet type, source IPv4 address, destination IPv4 address, protocol type, source port number, and destination port number. In V200R002C50 and later versions, the bound traffic classifier can match only the destination MAC address, source MAC address, Ethernet type, source IP address, destination IP address, protocol type, source port number, and destination port number.

  • When multiple simplified traffic policies based on the same ACL are applied in the same view, only one ACL resource is occupied.
  • For the CE12800, when an ACL-based simplified traffic policy is configured, a Layer 2 interface can only redirect Layer 2 packets and a VLANIF interface can redirect both Layer 2 and Layer 3 packets.
