Configuring the GbE Interconnect Switch Using the Console Management Interface

—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.

3.After making your changes, highlight APPLY, then press the Enter key.

NOTE: To save the configuration settings permanently, you must enter them into NVRAM using the Save Changes option on the main menu. Refer to the “Saving Changes” section earlier in this chapter.

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.
