DXS-3600 Series Layer 3 Managed 10Gigabit Ethernet Switch CLI Reference Guide
Command Mode
Interface Configuration Mode.
Command Default Level
Level: 12.
Usage Guideline
The command is only available for 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 listener query count - The number of group-specific queries sent before the router
assumes there are no local listeners of a group. The default number is the value of the
robustness variable.
User can increase this value if a subnet is expected to be loose.
Example
This example shows how to configure the robustness variable to be 3 on interface VLAN 1000.
Switch# configure terminal
Switch(config)# vlan 1000
Switch(config-vlan)# ipv6 mld snooping robustness-variable 3
Switch(config-vlan)#
63-15 ipv6 mld snooping static-group
This command is used to configure an MLD snooping static group. Use the no form of this command to
delete a static group.
ipv6 mld snooping static-group IPV6-ADDRESS interface INTERFACE-ID [,|-]
no ipv6 mld snooping static-group IPV6-ADDRESS [interface INTERFACE-ID [,|-]]
Parameters
IPV6-ADDRESS
interface INTERFACE-ID [,|-]
Default
No static-group is configured.
Command Mode
Interface Configuration Mode.
Command Default Level
Specifies an IPv6 multicast group address.
Specifies an interface or an interface list. No space is allowed before
and after the comma. The interface can be a physical interface or a
port-channel.
