DXS-3600 Series Layer 3 Managed 10Gigabit Ethernet Switch CLI Reference Guide
Usage Guideline
The command is only available for the VLAN interface configuration.
The robustness variable provides fine-tuning to allow for expected packet loss on an interface. 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 - The 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.
Users can increase this value if a subnet is expected to be loose.
Example
This example shows how to configure the MLD robustness variable to 3 for VLAN 1000.
Switch# configure terminal
Switch(config)# interface vlan1000
Switch(config-if)# ipv6 mld robustness-variable 3
Switch(config-if)#
64-7 ipv6 mld version
This command is used to change the MLD version on the specified interface. Use the no form of the
command to revert to the default setting.
ipv6 mld version {1 | 2}
no ipv6 mld version
Parameters
1
2
Default
The default MLD version is 2.
Command Mode
Interface Configuration Mode.
Command Default Level
Level: 12.
Usage Guideline
The command is only available for the VLAN interface configuration. The user can use this command to
modify the MLD query version on an interface.
Example
This example shows how to configure the MLD version 1.
Specifies to configure the switch to run MLD version 1.
Specifies to configure the switch to run MLD version 2.
