cisco.nxos.nxos_igmp_interface

Manages IGMP interface configuration.

Version added: 1.0.0

Synopsis

  • Manages IGMP interface configuration settings.

Parameters

Parameter Choices/Defaults Comments
group_timeout
string
Sets the group membership timeout for IGMPv2. Values can range from 3 to 65,535 seconds or keyword 'default'. The default is 260 seconds.
immediate_leave
boolean
    Choices:
  • no
  • yes
Enables the device to remove the group entry from the multicast routing table immediately upon receiving a leave message for the group. Use this command to minimize the leave latency of IGMPv2 group memberships on a given IGMP interface because the device does not send group-specific queries. The default is disabled.
interface
string / required
The full interface name for IGMP configuration. e.g. Ethernet1/2.
last_member_qrt
string
Sets the query interval waited after sending membership reports before the software deletes the group state. Values can range from 1 to 25 seconds or keyword 'default'. The default is 1 second.
last_member_query_count
string
Sets the number of times that the software sends an IGMP query in response to a host leave message. Values can range from 1 to 5 or keyword 'default'. The default is 2.
oif_ps
raw
Configure prefixes and sources for static outgoing interface (OIF). This is a list of dict where each dict has source and prefix defined or just prefix if source is not needed. The specified values will be configured on the device and if any previous prefix/sources exist, they will be removed. Keyword 'default' is also accepted which removes all existing prefix/sources.
oif_routemap
string
Configure a routemap for static outgoing interface (OIF) or keyword 'default'.
querier_timeout
string
Sets the querier timeout that the software uses when deciding to take over as the querier. Values can range from 1 to 65535 seconds or keyword 'default'. The default is 255 seconds.
query_interval
string
Sets the frequency at which the software sends IGMP host query messages. Values can range from 1 to 18000 seconds or keyword 'default'. The default is 125 seconds.
query_mrt
string
Sets the response time advertised in IGMP queries. Values can range from 1 to 25 seconds or keyword 'default'. The default is 10 seconds.
report_llg
boolean
    Choices:
  • no
  • yes
Configures report-link-local-groups. Enables sending reports for groups in 224.0.0.0/24. Reports are always sent for nonlink local groups. By default, reports are not sent for link local groups.
restart
boolean
    Choices:
  • no ←
  • yes
Restart IGMP. This is NOT idempotent as this is action only.
robustness
string
Sets the robustness variable. Values can range from 1 to 7 or keyword 'default'. The default is 2.
startup_query_count
string
Query count used when the IGMP process starts up. The range is from 1 to 10 or keyword 'default'. The default is 2.
startup_query_interval
string
Query interval used when the IGMP process starts up. The range is from 1 to 18000 or keyword 'default'. The default is 31.
state
string
    Choices:
  • present ←
  • absent
  • default
Manages desired state of the resource.
version
string
    Choices:
  • 2
  • 3
  • default
IGMP version. It can be 2 or 3 or keyword 'default'.

Notes

Note

  • Tested against NXOSv 7.3.(0)D1(1) on VIRL
  • Unsupported for Cisco MDS
  • When state=default, supported params will be reset to a default state. These include version, startup_query_interval, startup_query_count, robustness, querier_timeout, query_mrt, query_interval, last_member_qrt, last_member_query_count, group_timeout, report_llg, and immediate_leave.
  • When state=absent, all configs for oif_ps, and oif_routemap will be removed.
  • PIM must be enabled to use this module.
  • This module is for Layer 3 interfaces.
  • Route-map check not performed (same as CLI) check when configuring route-map with 'static-oif'
  • If restart is set to true with other params set, the restart will happen last, i.e. after the configuration takes place. However, 'restart' itself is not idempotent as it is an action and not configuration.
