set mld config

Use this command to set VLAN configuration parameters.

Syntax

set mld config vlan-list { [query-interval query-interval] [mld-version mld-version] [max-resp-time max-resp-time] [robustness robustness] [last-mem-int last-mem-int] [fast-leave fast-leave] [filter-id filter-id] [filter-status {enable | disable}]}

Parameters

vlan-list Applies this configuration to the specified VLAN(s). Valid values are 1 – 4094.
query-interval query-interval (Optional) Specifies the interval between the sending of host query messages by this device. Valid values are 1 – 31744 seconds. The default value is 125 seconds.
mld-version mld-version (Optional) Specifies the MLD version:
  • 1— MLDv1
  • 2— MLDv2 (default)
max-resp-time max-resp-time (Optional) Specifies the maximum response time advertised in MLD query messages. Valid values are 1 - 25 seconds for MLDv1 and 1 – 3174 seconds for MLDv2. Default value is 10 seconds.
robustness robustness (Optional) Specifies the robustness value which accounts for expected packet loss on a link. If a link is expected to be lossy, the robustness value may be increased. Valid values are 2 – 255. Default value is 2.
last-mem-int last-mem-int (Optional) Specifies the last member interval which is the length of time that must pass before a router decides that there is no longer another router which should be the querier on a link. This value is normally set to the robustness value times the query interval, plus one half of one maximum response time. Valid values are 1 - 255 seconds for MLDv1 and 1 – 3174 seconds for MLDv2. Default value is 10 seconds.
fast-leave fast-leave (Optional) Sets the VLANs fast leave state. Valid values are 1 for enable or 2 for disable. Default value is 2.
filter-id filter-id (Optional) Assigns an input filter to the VLAN. Specify the filter ID of the input filter.

You can apply only one input filter to a VLAN. You can, however, apply an input filter to more than one VLAN.
filter-status If you assign an input filter to the VLAN, you must enable the input filter for the filter to take effect.
  • enable — Enable the input filter assigned to the VLAN
  • disable — Disable the input filter assigned to the VLAN

Defaults

At least one optional parameter must be entered.

If not specified:

  • query-interval defaults to 125 seconds
  • mld-version defaults to MLDv2
  • max-resp-time defaults to 10 seconds
  • robustness defaults to 2
  • last-mem-int defaults to 10 seconds
  • fast-leave defaults to 2 (disabled)
  • filter-status defaults to disable

Mode

All command modes.

Usage

The maximum response time is used to tune the burstiness of MLD messages on the link. Larger values make the traffic less bursty, as host responses are spread out over a larger interval. The maximum response time must be less than the query interval.

Example

This example shows how to set the query interval on VLAN 104 to 150 seconds:

S Chassis(rw)->set mld config 104 query-interval 150
S Chassis(rw)->
