Static Port Configuration Example - HP FlexFabric 5700 Series Configuration Manual

(0.0.0.0, 224.1.1.1)
Host slots (0 in total):
Host ports (2 in total):
XGE1/0/3
XGE1/0/4
The output shows the following information:
Host A and Host B have joined the multicast group 224.1.1.1 through the member ports
•
Ten-GigabitEthernet 1/0/4 and Ten-GigabitEthernet 1/0/3 on Switch A, respectively.
Host A and Host B have failed to join the multicast group 224.2.2.2. It means that the multicast
•
group policy has taken effect.

Static port configuration example

Network requirements
As shown in
Router A runs IGMPv2 and acts as the IGMP querier. Switch A, Switch B, and Switch C run IGMPv2
•
snooping.
• Host A and host C are permanent receivers of multicast group 224.1.1.1.
Configure static ports to meet the following requirements:
• To enhance the reliability of multicast traffic transmission, configure Ten-GigabitEthernet 1/0/3
and Ten-GigabitEthernet 1/0/5 on Switch C as static member ports for multicast group 224.1.1.1.
Suppose the STP runs on the network, and the forwarding path from Switch A to Switch C is blocked
•
to avoid data loops. Multicast data flows to the receivers attached to Switch C only along the path
of Switch A—Switch B—Switch C. Configure Ten-GigabitEthernet 1/0/3 on Switch A as a static
router port. As a result, multicast data can flow to the receivers nearly uninterruptedly along the path
of Switch A—Switch C when the path of Switch A—Switch B—Switch C is blocked.
NOTE:
If no static router port is configured, multicast transmission is interrupted for a while after the path of
Switch A—Switch B—Switch C is blocked. The reason is that at least one IGMP query/response exchange
is required before the new path can forward multicast packets.
For more information about the STP, see Layer 2—LAN Switching Configuration Guide.
