Query Interval
—Enter a value between 1 and 65,500 seconds, with a default of
125 seconds. This setting specifies the length of time between sending IGMP queries.
—
Max Response
—Set the maximum amount of time allowed before sending an IGMP
response report. A value between 1 and 25 seconds can be entered; the default is
10 seconds.

Configuring Port Trunking
Port trunking allows several ports to be grouped together to act as a single link. This setting
provides a bandwidth that is a multiple of a single link bandwidth. Port trunking is most
commonly used to link a bandwidth-intensive network device or devices, such as a server, to
the backbone of a network.
The GbE Interconnect Switch allows the creation of up to six port trunking groups, each
group consisting of up to eight links (ports). The trunked ports must be contiguous (they must
have sequential port numbers). All of the ports in the group must be members of the same
VLAN. Further, the trunked ports must all be of the same speed and should be configured as
full-duplex.
The configuration of the lowest numbered port in the group becomes the configuration for all
of the ports in the aggregation group. This port is called the Master Port of the group, and all
configuration options, including the VLAN configuration, that can be applied to the Master
Port are applied to the entire port trunking group.
Load balancing is automatically applied to the ports in the trunked group, and a link failure
within the group causes the network traffic to be directed to the remaining links in the group.
The Spanning Tree Protocol treats a port trunking group as a single link on the GbE
Interconnect Switch level. On the port level, the STP uses the port parameters of the Master
Port in the calculation of port cost and in determining the state of the port trunking group. If
two redundant port trunking groups are configured on the GbE Interconnect Switch, STP
blocks one entire group, in the same way STP blocks a single port that has a redundant link.
