ProLiant BL p-Class GbE Interconnect Switch Web-based Interface Reference Guide

Configuring the GbE Interconnect Switch using the Web-based Interface
To configure IGMP snooping:
1. Select IGMP Snooping from the Configuration menu. The following screen is
displayed.
2. Select a VID number in the VLAN ID field.
3. Select Enabled in the State field.
4. In the Querier State field, select the IGMP version that will be used by the IGMP
interface when making queries. Select from Non-Querier, V1-Querier, and
V2-Querier.
5. In the Robustness Variable field, type a value between 1 and 255. Larger values are
specified for subnets that are expected to lose larger numbers of packets. The default is 2.
The robustness variable is a tuning variable that allows you to configure the acceptable
number of packets that may be lost.
6. In the Query Interval field, type a value between 1 and 65,500 seconds to specify the
length of time between sending IGMP queries. The default is 125 seconds.
7. In the Max Response field, type the maximum amount of time allowed before sending an
IGMP response report. The range is 1 to 25 seconds.
8. Click Apply.
IMPORTANT: To save the configuration settings permanently, you must enter them into NVRAM
using the Save Changes option on the Maintenance menu. Refer to the section, “Saving
Changes,” earlier in this chapter.
Configuring Spanning Tree Protocol Settings
IEEE 802.1D Spanning Tree Protocol (STP) allows for the blocking of links between
switches to avoid loops within the network. When multiple links between the switches are
detected, a primary link is established. Duplicated links are blocked from use and become
standby links. The protocol allows for the duplicate links to be used in the event of a failure
of the primary link. Once STP is configured and enabled, primary links are established and
duplicated links are blocked and put into standby automatically. The reactivation of the
blocked links (at the time of a primary link failure) is also accomplished automatically,
without operator intervention.
