Changing the Query Response Interval
To set the query response interval, use the following command:
set igmp qri
tenth-seconds
[
vlan
vlan-id
]
You can specify a value from 1 through 65,535 tenths of a second. The default is 100 tenths
of a second (10 seconds).
Changing the Last Member Query Interval
To set the last member query interval, use the following command:
set igmp lmqi
tenth-seconds
[
vlan
vlan-id
]
You can specify a value from 1 through 65,535 tenths of a second. The default is 10 tenths
of a second (1 second).
Changing Robustness
Robustness adjusts the IGMP timers to the amount of traffic loss that occurs on the
network. Set the robustness value higher to adjust for more traffic loss. To change the
robustness value, use the following command:
set igmp rv
num
[
vlan
vlan-id
]
You can specify a value from 2 through 255. The default is 2.
Enabling Router Solicitation
A DWS-1008 switch can search for multicast routers by sending multicast router solicitation
messages. This message invites multicast routers that receive the message and that support
router solicitation to immediately advertise themselves to the switch. Router solicitation is
disabled by default.
The MSS implementation of router solicitation is based on
draft-ietf-idmr-igmp-mrdisc-
09.txt
.
To enable or disable multicast router solicitation, use the following command:
set igmp mrsol
{
enable
|
disable
} [
vlan
vlan-id
]
Changing the Router Solicitation Interval
The default multicast router solicitation interval is 30 seconds. To change the interval, use the
following command:
set igmp mrsol mrsi
seconds
[
vlan
vlan-id
]
You can specify 1 through 65,535 seconds. The default is 30 seconds.
