config mld_snooping querier
Purpose
Used to configure the timers and settings for the MLD snooping querier for the Switch.
Syntax
config mld_snooping querier [ vlan <vlan_name 32> |all] { query_interval <sec 1-
65535> | max_response_time <sec 1-25> | robustness_variable <value 1-255> |
last_listener_query_interval <sec 1-25> | state [enable|disable] | version <value 1-
2>} (1)
Description
This command is used to configure the time between general query transmissions, the
maximum time to wait for reports from listeners and the permitted packet loss guaranteed
by MLD snooping.
Parameters
vlan <vlan_name 32>
−
The name of the VLAN for which to configure the MLD querier.
all
– Specifies all VLANs are to be configured for the MLD querier.
query_interval <sec 1–65535>
– Specifies the amount of time between general query
transmissions. The user may specify a time between 1 and 65535 seconds with a default
setting of 125 seconds.
max_response_time <sec 1–25> –
The maximum time to wait for reports from listeners.
The user may specify a time between 1 and 25 seconds with a default setting of 10
seconds.
robustness_variable <value 1–255> –
Provides fine–tuning to allow for expected packet
loss on a subnet. The user may choose a value between 1 and 255 with a default setting
of 2. If a subnet is expected to be lossy, the user may wish to increase this interval.
last_listener_query_interval <sec 1–25> –
The maximum amount of time to be set
between group–specific query messages. This interval may be reduced to lower the
amount of time it takes a router to detect the loss of a last listener group. The user may
set this interval between 1 and 25 seconds with a default setting of 1 second.
state [enable | disable] –
Enabling the querier state will
set the Switch as a MLD querier
and disabling it will set it as a Non–querier. The default setting is disabled.
version <value 1-2>
–
Configure the MLD version of the query packet which will be sent
by the router. The default is 2.
Restrictions
Only Administrator and Operator-level users can issue this command.
Example usage:
To configure the MLD snooping querier:
