How Do I Configure Multicast Packet Suppression to Reduce Impact of a Large Number of Low-Rate Multicast Packets on the Wireless Network?

Example for Configuring Multicast Packet Suppression In Direct Forwarding Mode

1. Create the traffic classifier test and define a matching rule.

   <HUAWEI> system-view
   [HUAWEI] sysname SwitchA
   [SwitchA] traffic classifier test
   [SwitchA-classifier-test] if-match destination-mac 0100-5e00-0000 mac-address-mask ffff-ff00-0000   //Match the destination MAC address of multicast packets.
   [SwitchA-classifier-test] quit
   

2. Create the traffic behavior test, enable traffic statistics collection, and set the traffic rate limit.

   [SwitchA] traffic behavior test
   [SwitchA-behavior-test] statistic enable
   [SwitchA-behavior-test] car cir 100   //Set the rate limit to 100 kbit/s. If multicast services are available, you are advised to set the rate limit according to the service traffic.
   [SwitchA-behavior-test] quit
   

3. Create the traffic policy test and bind the traffic classifier and traffic behavior to the traffic policy.

   [SwitchA] traffic policy test
   [SwitchA-trafficpolicy-test] classifier test behavior test
   [SwitchA-trafficpolicy-test] quit
   

4. Apply the traffic policy to inbound or outbound directions of interfaces.

   [SwitchA] interface gigabitethernet 0/0/1
   [SwitchA-GigabitEthernet0/0/1] traffic-policy test inbound
   [SwitchA-GigabitEthernet0/0/1] traffic-policy test outbound
   [SwitchA-GigabitEthernet0/0/1] quit
   

Example for Configuring Multicast Suppression in Tunnel Forwarding Mode

In V200R005, the configuration procedure is as follows:

1. Create the traffic classifier test and define a matching rule.

   <AC6605> system-view
   [AC6605] traffic classifier test
   [AC6605-classifier-test] if-match destination-mac 0100-5e00-0000 mac-address-mask ffff-ff00-0000   //Match the destination MAC address of multicast packets.
   [AC6605-classifier-test] quit
   

2. Create the traffic behavior test, enable traffic statistics collection, and set the traffic rate limit.

   [AC6605] traffic behavior test
   [AC6605-behavior-test] statistic enable
   [AC6605-behavior-test] car cir 100   //Set the rate limit to 100 kbit/s. If multicast services are available, you are advised to set the rate limit according to the service traffic.
   [AC6605-behavior-test] quit
   

3. Create the traffic policy test and bind the traffic classifier and traffic behavior to the traffic policy.

   [AC6605] traffic policy test
   [AC6605-trafficpolicy-test] classifier test behavior test
   [AC6605-trafficpolicy-test] quit
   

4. Apply the traffic policy to inbound or outbound directions of interfaces.

   [AC6605] interface wlan-ess 1
   [AC6605-Wlan-Ess1] traffic-policy test inbound
   [AC6605-Wlan-Ess1] traffic-policy test outbound
   [AC6605-Wlan-Ess1] quit
   

In V200R006 and later versions, the configuration procedure is as follows:

1. Create the traffic profile test and set the maximum traffic volume of multicast packets in the profile.

   <AC6605> system-view
   [AC6605] wlan
   [AC6605-wlan-view] traffic-profile name test
   [AC6605-wlan-traffic-prof-test] traffic-optimize multicast-suppression packets 100   //Set the maximum traffic volume of multicast packets to 100 pps. If multicast services are available, you are advised to set the rate limit according to the service traffic.
   [AC6605-wlan-traffic-prof-test] quit
   

2. Bind the traffic profile to the VAP profile.

   [AC6605-wlan-view] vap-profile name test
   [AC6605-wlan-vap-prof-test] traffic-profile test
   [AC6605-wlan-vap-prof-test] quit
