set igmp config

Use this command to configure IGMP settings on one or more VLANs.

Syntax

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

Parameters

vlan-list Specifies the VLAN(s) on which to configure IGMP.
query-interval query-interval (Optional) Specifies the frequency of host-query frame transmissions. Valid values are from 1–31744 seconds. This value works together with max-resp-time to remove ports from an IGMP group.
igmp-version igmp-version (Optional) Specifies the IGMP version. Valid values are:
  • 1 — IGMP V1
  • 2 — IGMP V2
  • 3 — IGMP V3
max-resp-time max-resp-time (Optional) Specifies the maximum query response time. Valid values for IGMP V1 and V2 are 1–25 seconds; IGMP V3 are 0– 3174 seconds. This value works together with query-interval to remove ports from an IGMP group.
robustness robustness (Optional) Specifies the robustness value. This can be increased to tune for expected packet loss on a subnet. Valid values are 2–255.
last-mem-int last-mem-int (Optional) Specifies the Last Member Query Interval. This is the maximum response time inserted into group-specific queries which are sent in response to Leave Group messages. It is also the amount of time between group-specific query messages. Valid values are 1–2550– 3174 tenths of a second.
fast-leave fast-leave (Optional) Set the VLAN‘s fast leave state.
  • 1 — Enable
  • 2 — Disable

The fast leave setting is applied to both IGMP and MLD regardless of which protocol it is set in.
rtr-alert-checking 
rtr-alert-checking (Optional) Specifies whether router alert checking is required.
  • 1 — Force (true)
  • 2 — Don‘t force (false)
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

You must specify at least one optional parameter.

  • query-interval = 125
  • igmp-version = 2
  • max-resp-time = 10
  • robustness = 2
  • last-mem-int = 10
  • fast-leave = 2 (disabled)
  • rtr-alert-checking = 1 (true)
  • filter-status = disable

Mode

All command modes.

Examples

This example shows how to set the IGMP query interval time to 250 seconds on VLAN 1:

System(rw)->set igmp config 1 query-interval 250

This example shows how to assign input filter 1 and enable it on VLAN 10:

System(rw)->set igmp config 10 filter-id 1 filter-status enable
