69-10 config mld_snooping querier
Description
This command is used to configure the time, in seconds, between general query transmissions,
the maximum time to wait for reports from listeners, and the permitted packet loss that guarantees
MLD snooping.
Format
config mld_snooping querier [vlan_name <vlan_name 32> | vlanid <vlanid_list> | all]
{query_interval <sec 1-65535> | max_response_time <sec 1-25> | robustness_variable
<value 1-7> | last_listener_query_interval <sec 1-25> | state [enable | disable] | version
<value 1-2>} (1)
Parameters
vlan_name - Specifies the name of the VLAN for which MLD snooping querier is to be
configured.
<vlan_name 32> - Enter the VLAN name. The maximum length is 32 characters.
vlanid - Specifies the ID of the VLAN for which MLD snooping querier is to be configured.
<vlanid_list> - Enter the VLAN ID list.
all - Specifies all VLANs for which MLD snooping querier is to be configured.
query_interval - Specifies the amount of time in seconds between general query transmissions.
<sec 1-65535> - Enter the amount of time in seconds between general query transmissions.
The default setting is 125 seconds.
max_response_time - Specifies the maximum time in seconds to wait for reports from members.
<sec 1-25> - Enter the maximum time in seconds to wait for reports from members. The
default setting is 10 seconds.
robustness_variable - Provides fine-tuning to allow for expected packet loss on a subnet. The
value of the robustness variable is used in calculating the following MLD message intervals:
1. Group member interval—Amount of time that must pass before a multicast router
decides there are no more members of a group on a network. This interval is
calculated as follows: (robustness variable x query interval) + (1 x query response
interval).
