ProSAFE FS526Tv2, FS726Tv2, and FS728TLP Smart Switches The Querier VLAN Status screen displays. The following figure contains examples. The following table describes the fields of the Querier VLAN Status screen. Field Description VLAN ID The VLAN ID on which the IGMP snooping querier is administratively enabled and for which a VLAN exists in the VLAN database. Operational State Specifies the operational state of the IGMP snooping querier on the VLAN: • Querier. The querier is the active IGMP snooping querier in the VLAN. The smart switch sends periodic queries. If the smart switch detects a better querier (that is, with a numerically lower IP address) on the VLAN, it moves to the Non-Querier state. • Non-Querier. The querier functions in the Non-Querier state on the VLAN. When the querier expiry interval timer expires, the querier moves to the Querier state. • Disabled. The querier is configured but disabled on the VLAN. The querier moves to the Disabled state in any of the following conditions: - IGMP snooping is not operational on the VLAN. - The querier IP address is not configured. - The network management address is not configured. Operational Version The IGMP protocol version of the querier. Last Querier Address The IP address of the last querier that snooped on the VLAN. Last Querier Version The IGMP protocol version of the last querier that snooped on the VLAN. The last querier version can differ from the operational version because the smart switch supports IGMPv2, IGMPv2, and IGMPv3 concurrently. Operational Max Response Time The period in which a snooping query needs to be responded to. This is the value that you configure in the Maximum Response Time field on the IGMP Snooping VLAN Configuration screen (see Configure IGMP Snooping for VLANs on page 115). 2.
