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).
3. Last member query countNumber 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 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 - Specify 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
forward from router ports or VLAN flooding.
<value 1-2> - Specify the values between 1 and 2.
Restrictions
Only Administrator, Operator and Power-User level users can issue this command.
Example
To configure the MLD snooping querier:
DGS-3420-28SC: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.
DGS-3420-28SC:admin#
55-11 config mld_snooping mrouter_ports
Description
This command allows users to designate a range of ports as being connected to multicast-enabled
routers. This will ensure that all packets with such a router as its destination will reach the
multicast-enabled router, regardless of protocol.
Format
config mld_snooping mrouter_ports [vlan <vlan_name 32> | vlanid <vlanid_list>] [add |
delete] <portlist>
Parameters
vlan - Specify the name of the VLAN on which the router port resides.
