ProSafe Managed Switch Field Description Query Interval The amount of time in seconds that a Snooping Querier waits before sending out the periodic general query. Querier Timeout The amount of time to wait in the Non-Querier operational state before moving to a Querier state. When you specify a value for , the following additional information appears. Field Description VLAN Admin Mode Indicates whether iGMP Snooping Querier is active on the VLAN. VLAN Operational State Indicates whether IGMP Snooping Querier is in "Querier" or "Non-Querier" state. When the switch is in Querier state, it will send out periodic general queries. When in Non-Querier state, it will wait for moving to Querier state and does not send out any queries. VLAN Operational Max Response Time Indicates the time to wait before removing a Leave from a host upon receiving a Leave request. This value is calculated dynamically from the Queries received from the network. If the Snooping Switch is in Querier state, then it is equal to the configured value. Querier Election Indicates whether the IGMP Snooping Querier participates in querier election if it Participation discovers the presence of a querier in the VLAN. Querier VLAN The IP address will be used in the IPv4 header while sending out IGMP queries on this Address VLAN. It can be configured using the appropriate command. Operational Version The version of IPv4 will be used while sending out IGMP queries on this VLAN. Last Querier Address Indicates the IP address of the most recent Querier from which a Query was received. Last Querier Version Indicates the IGMP version of the most recent Querier from which a Query was received on this VLAN. When the optional argument detail is used, the command shows the global information and the information for all Querier-enabled VLANs. MLD Snooping Commands This section describes commands used for MLD Snooping. In IPv4, Layer 2 switches can use IGMP Snooping to limit the flooding of multicast traffic by dynamically configuring Layer 2 interfaces so that multicast traffic is forwarded only to those interfaces associated with IP multicast addresses. In IPv6, MLD Snooping performs a similar function. With MLD Snooping, IPv6 multicast data is selectively forwarded to a list of ports that want to receive the data, instead of being flooded to all ports in a VLAN. This list is constructed by snooping IPv6 multicast control packets. Switching Commands 180

MLD Snooping Commands

This section describes commands used for MLD Snooping. In IPv4, Layer 2 switches can use

IGMP Snooping to limit the flooding of multicast traffic by dynamically configuring Layer 2

interfaces so that multicast traffic is forwarded only to those interfaces associated with IP

multicast addresses. In IPv6, MLD Snooping performs a similar function. With MLD

Snooping, IPv6 multicast data is selectively forwarded to a list of ports that want to receive

the data, instead of being flooded to all ports in a VLAN. This list is constructed by snooping

IPv6 multicast control packets.

Query Interval

The amount of time in seconds that a Snooping Querier waits before sending out the

periodic general query.

Querier Timeout

The amount of time to wait in the Non-Querier operational state before moving to a

Querier state.

Field

Description

Indicates whether iGMP Snooping Querier is active on the VLAN.

Indicates whether IGMP Snooping Querier is in “Querier” or “Non-Querier” state. When

the switch is in

Querier

state, it will send out periodic general queries. When in

Non-Querier

state, it will wait for moving to Querier state and does not send out any

queries.

Indicates the time to wait before removing a Leave from a host upon receiving a Leave

request. This value is calculated dynamically from the Queries received from the

network. If the Snooping Switch is in Querier state, then it is equal to the configured

value.

Indicates whether the IGMP Snooping Querier participates in querier election if it

discovers the presence of a querier in the VLAN.

The IP address will be used in the IPv4 header while sending out IGMP queries on this

VLAN. It can be configured using the appropriate command.

The version of IPv4 will be used while sending out IGMP queries on this VLAN.

Indicates the IP address of the most recent Querier from which a Query was received.

Indicates the IGMP version of the most recent Querier from which a Query was received

on this VLAN.
