Local Management: Overview, Setup, and Navigation
Last Member Query Interval (Modifiable)
This field is the Max Response Time inserted into Group-Specific Queries sent in
response to Leave Group messages, and is also the amount of time between
Group-Specific Query messages. This value may be tuned to modify the leave
latency of the network. A reduced value results in reduced time to detect the loss
of the last member of a group. The interval is in tenths of seconds. This value is
not used if the switch is not the querier. The field will initially display an asterisk
(*) if the VLAN ID is set to ALL, then it will be modifiable.
Querier Address (Read-Only)
This field displays the address of the IGMP Querier on the IP subnet to which this
VLAN is attached. This field will display an asterisk (*) when VLANID is set to
ALL.
Querier Uptime (Read-Only)
This field displays the number of seconds that the current IGMP Querier has been
operational since the last change in Queriers. Will display an asterisk (*) when
VLANID is set to ALL.
Querier Expire Time (Read-Only)
This field displays the number of seconds remaining before the Other Querier
Present Timer expires. If the local system (current device displayed) is the querier,
the value of this object is zero. This field will display an asterisk (*) when LANID
is set to ALL.
VLAN ID (Selectable)
This field displays the Identifying number for the VLANs available to be
modified. The information in the Configuration and Statistics fields applies only
to this VLAN ID number. The Space Bar is used to toggle through all available
VLAN IDs.
The option ALL in this selection allows the parameters for all connected VLANs
to be changed globally, including IGMP State and all items under Configuration.
To update the Configuration and Statistics fields, use the SAVE command. When
ALL is chosen as the selection for VLAN ID, asterisks (*) will be displayed in the
Configuration, Statistics, and IGMP State fields. Although selectable as detailed
below, IGMP State will display asterisks initially when ALL is chosen in the
VLAN ID field. The fields that are selectable or modifiable will initially display
asterisks, but then the Space Bar can be used to display the selectable fields, and
the numeric keys can be used for the modifiable fields to change them.
