Static Port Configuration Example - HP FlexNetwork 7500 Series Configuration Manual

Verifying the configuration
# Send IGMP reports from Host A and Host B to join multicast groups 224.1.1.1 and 224.2.2.2.
(Details not shown.)
# Display dynamic IGMP snooping forwarding entries for VLAN 100 on Switch A.
[SwitchA] display igmp-snooping group vlan 100
Total 1 entries.
VLAN 100: Total 1 entries.
(0.0.0.0, 224.1.1.1)
Host slots (0 in total):
Host ports (2 in total):
GE1/0/3
GE1/0/4
The output shows the following information:
•
Host A and Host B have joined multicast group 224.1.1.1 through the member ports
GigabitEthernet 1/0/3 and GigabitEthernet1/0/4 on Switch A, respectively.
•
Host A and Host B have failed to join multicast group 224.2.2.2.

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 GigabitEthernet 1/0/3 and
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. To avoid data loops, the forwarding path from Switch A
to Switch C is blocked. Multicast data flows to the receivers attached to Switch C only along the
path of Switch A—Switch B—Switch C. When this path is blocked, at least one IGMP
query-response cycle must be completed before multicast data flows to the receivers along the
path of Switch A—Switch C. In this case, the multicast delivery is interrupted during the process.
For more information about the STP, see Layer 2—LAN Switching Configuration Guide.
Configure GigabitEthernet 1/0/3 on Switch A as a static router port. Then, 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.
