DGS-3710 Series Layer 2 Managed Gigabit Switch CLI Reference Guide
429
<sec 1-65535>
- Specifies 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>
- Specifies 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>
- Specifies 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
- Specifies 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>
- Specifies the time between 1 and 25 seconds.
state
- This allows the switch 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 switch to be selected as an MLD Querier (sends MLD query packets).
disable
- When disabled, the switch can not play the role as a querier.
version
- Specifies the version of MLD packet that will be sent by this port. If a MLD packet
received by the interface has a version higher than the specified version, this packet will be
dropped.
<value 1-2>
- Specifies the values between 1 and 2.
Restrictions
Only Administrator and Operator-level users can issue this command.
Example
To configure the MLD snooping querier:
DGS-3710-12C:admin#config mld_snooping querier vlan_name default query_interval
125 state enable
Command: config mld_snooping querier vlan_name default query_interval 125 state
enable
Success.
