Installation and Getting Started Guide
NOTE: You must reload the software after making this configuration change and saving it to the startup-config
file.
USING THE CLI
To modify the query interval, enter a command such as the following:
HP6208(config)# ip multicast query-interval 120
Syntax: [no] ip multicast query-interval <interval>
The <interval> parameter specifies the interval between queries. You can specify a value from 10 – 600 seconds.
The default is 60 seconds.
USING THE WEB MANAGEMENT INTERFACE
You cannot configure this feature using the Web management interface.
Modifying the Age Interval
When the HP 6208M-SX receives a Group Membership report, the switch makes an entry in the IGMP group table
for the group in the report. The age interval specifies how long the entry can remain in the table without the switch
receiving another Group Membership report.
To modify the age interval, use the following CLI method.
NOTE: You must reload the software after making this configuration change and saving it to the startup-config
file.
USING THE CLI
To modify the age interval, enter a command such as the following:
HP6208(config)# ip multicast age-interval 280
Syntax: [no] ip multicast age-interval <interval>
The <interval> parameter specifies the interval between queries. You can specify a value from 10 – 1220
seconds. The default is 140 seconds.
USING THE WEB MANAGEMENT INTERFACE
You cannot configure this feature using the Web management interface.
Filtering Multicast Groups
By default, the HP 6208M-SX forwards multicast traffic for all valid multicast groups. You can configure the HP
6208M-SX to filter out all multicast traffic for groups other than the ones for which the switch has received Group
Membership reports.
Thus configured, the switch forwards all multicast groups once the switch is started, until the switch receives a
Group Membership report. Once the switch receives a Group Membership report, the switch drops all multicast
packets for groups other than the ones for which the switch has received the Group Membership report. Once the
switch receives a Group Membership report for a given group, the switch forwards traffic for that group instead of
dropping the traffic.
To enable IP multicast filtering, use the following CLI method.
NOTE: You must reload the software after making this configuration change and saving it to the startup-config
file.
USING THE CLI
To enable IP multicast filtering, enter the following command:
HP6208(config)# ip multicast filter
Syntax: [no] ip multicast filter
