The S9300 uses this interface to communicate with hosts. On the S9300, VLANIF
interfaces and loopback interfaces support IGMP.
3. Run:
igmp timer query seconds
The interval for sending IGMP General Query messages is set.
By default, the interval for sending IGMP General Query messages is 60 seconds.
4. Run:
igmp robust-count robust-value
The IGMP robustness variable is set.
When the system starts, the system sends General Query messages for the times
–
specified by the value of the robustness variable. The interval for sending messages
is 1/4 of the interval for sending IGMP General Query messages.
When receiving a Leave message, the S9300 sends IGMP Group-Specific Query
–
messages for the time specified by the value of the robustness variable at the
interval that you set.
By default, the robustness variable is 2.
5. Run:
igmp max-response-time interval
The maximum response time for IGMP Query messages is set.
By default, the maximum response time for an IGMP Query message is 10 seconds.
6. Run:
igmp timer other-querier-present interval
The Keepalive period of other IGMP queriers is set.
By default, Keepalive period of other IGMP queriers = Robustness variable x Interval
for sending General Query messages + Maximum response time x 1/2. When the
values of the parameters to the right of the equal mark are the default values, the
Keepalive period of other IGMP queriers is 125 seconds.
7. Run:
igmp lastmember-queryinterval interval
The interval at which the S9300 sends IGMP Group-Specific Query messages is set.
By default, the interval for sending IGMP Group-Specific Query messages is 1 second.
8. Run:
igmp on-demand
The (S, G) entry never times out. The interface does not send IGMP Query messages.
By default, the interface sends Query messages and participates in querier election.
NOTE
The igmp on-demand command is valid only when IGMPv2 is used.
