Query Time
Allows a user to control the number of IGMP messages allowed on the subnet by
varying the
Query Interval
(the Query Interval is the interval between general
queries sent by the multicast router).
This field affects only the VLAN specified in the screen’s VLAN field (for example, if
you change the Query Time value field on the VLAN specified in the screen’s VLAN
field, other VLANs are not affected).
Default Value 125 seconds
Range 1 to 512 seconds
Set Router Ports
Selects the IGMP version according to the IGMPv1 (Version 1) or IGMPv2 (Version
2) standard (see RFC 2236). Use this field in conjunction with the Static Router
Ports field (see next field description) to select the IGMP version to set.
You can also use this field to view which static router ports are set to Version 1 or to
Version 2. Use the space bar to toggle between the two versions and view the static
router ports settings.
This field affects all VLANs (for example, if you change the value of the Set Router
Ports field on the VLAN specified in the screen’s VLAN field, ALL VLANs are
affected).
Default Value Version 1
Range Version 1, Version 2
Static Router Ports
Allows a user to assign switch ports to any port that has a path to a multicast router.
When the unit is part of a stack configuration, the screen displays the unit numbers
of the switches configured in the stack, along with the corresponding ports.
The configured ports do not filter any IP multicast traffic. The Static Router Ports
fields are displayed in six-port groups (for example, 1-6, 7-12, 13-18). The number
of ports displayed depends on the switch model or type of optional MDA that is
installed in the Uplink Module slot.
This field affects all VLANs (for example, if you assign a port as a static router port in
this screen, the port becomes a static router port for the VLAN specified in the
screen’s VLAN field, and also for any other VLAN where this port is a member).
