41. MLD Snooping Commands
380

Parameters
vlan_name
Specify the name of the VLAN for which MLD snooping querier is to be configured.
<vlan_name 32>
Specify the VLAN name. The maximum length is 32 characters.
vlanid Specify the ID of the VLAN for which MLD snooping querier is to be configured.
<vlanid_list>
Specify the VLAN ID list.
all Specify all VLANs for which MLD snooping querier is to be configured.
query_interval
Specify the amount of time in seconds between general query transmissions.
<sec 1-65535>
Specify the amount of time in seconds between general query transmissions. The
default setting is 125 seconds.
max_response_time
Specify the maximum time in seconds to wait for reports from members.
<sec 1-25>
Specify 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:
・ 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).
・ Other querier present interval - Amount of time that must pass before a multicast
router decides that there is no longer another multicast router that is the querier. This
interval is calculated as follows:
(robustness variable x query interval) + (0.5 x query response interval).
・ Last member query count - Number of group-specific queries sent before the router
assumes there are no local members of a group. The default number is the value of
the robustness variable.
<value 1-7>
Specify the value between 1 and 7. Increase the value if you expect a subnet to be
lossy. The robustness variable is set to 2 by default.
last_member_query_interval
Specify the maximum amount of time between group-specific query messages, including
those sent in response to leave-group messages. You might lower this interval to reduce
the amount of time it takes a router to detect the loss of the last member of a group.
<sec 1-25>
Specify the time between 1 and 25 seconds.
state This allows the Switching Hub to be specified as an MLD Querier (sends MLD query
packets) or a Non-Querier (does not send MLD query packets). Set to enable or disable.
enable
Allows the Switching Hub to be selected as an MLD Querier (sends MLD query
packets).
disable
When disabled, the Switching Hub can not play the role as a querier.
