# Monitoring IGMP Proxy

To display IGMP proxy parameters, use the following show commands.

show ip igmp-proxy

- Use to display IGMP proxy parameters for a VR.
- Field descriptions
  - Routing Process—IGMP proxy protocol
  - Administrative state—State of IGMP proxy in the software: enabled or disabled
  - Operational state—Operational state of IGMP proxy: enabled or disabled
  - total interface—Number of IGMP proxy interfaces on the VR; currently only one upstream interface per VR
  - state—Operational state of the IGMP proxy interfaces: enabled or disabled
  - multicast group—Number of multicast groups associated with IGMP proxy interfaces
- Example

      host1#show ip igmp-proxy
      Routing Process IGMP Proxy, Administrative state enabled, Operational state enabled
      total 1 upstream interface, state enabled
          6 multicast group

- See show ip igmp-proxy.

show ip igmp-proxy groups

- Use to display information about multicast groups that IGMP proxy reported.
- Field descriptions
  - Grp Address—Address of the multicast group
  - Interface—Type and specifier of the upstream interface associated with the multicast group
  - Member State—State of the associated group address and interface
    - Idle—Interface is going to send a group membership report to respond to a group membership query for this group
    - Delay—Interface has responded to the latest group membership query for this group
  - count—Total number of multicast groups associated with this interface
- Example 1

      host1#show ip igmp-proxy groups

      Grp Address     Interface       Member State
      --------------- --------------- --------------
      225.1.1.1       atm3/0.2          Idle
      225.1.1.2       atm3/0.2          Idle
      225.1.1.3       atm3/0.2          Idle
      225.1.1.4       atm3/0.2          Idle
      225.1.1.5       atm3/0.2          Idle
      225.1.1.6       atm3/0.2          Idle
      count 6

- Example 2

      host1#show ip igmp-proxy group 225.1.1.1
      Grp Address     Interface       Member State
      --------------- --------------- --------------
      225.1.1.1       atm3/0.2        Idle

- Example 3

      host1#show ip igmp-proxy group count
      Count: 6 groups

- See show ip igmp-proxy groups.

show ip igmp-proxy interface

- Use to display information about the interface on which you configured IGMP proxy.
- To view information about a particular interface, enter an interface type and specifier, such as atm 3/0. For details about interface types and specifiers, see Interface Types and Specifiers in JUNOSe Command Reference Guide.
- Specify the brief keyword to display a summary rather than a detailed description.
- Field descriptions
  - Interface—Type of upstream interface. For details about interface types, see Interface Types and Specifiers in JUNOSe Command Reference Guide.
  - address—Address of upstream interface
  - Administrative state—State of upstream interface in the software: enabled or disabled
  - Operational state—Physical state of upstream interface: enabled or disabled
  - Version—IGMP version on this interface
  - State—Presence of IGMPv1 routers on the same subnet as this upstream interface
  - Unsolicited report interval—Time interval, in tenths of a second, at which this upstream interface sends an unsolicited group membership report
  - Version 1 router present timeout—How long, in seconds, that the upstream interface calculates an IGMPv1 router to exist on the subnet after that interface receives an IGMPv1 group membership query
  - multicast group—Number of multicast groups associated with this upstream interface
  - Interface statistics Rcvd—Statistics for messages received on this interface
    - v1 queries—Number of IGMPv1 group membership queries received
    - v2 queries—Number of IGMPv2 group membership queries received
    - v1 reports—Number of IGMPv1 group membership reports received
    - v2 reports—Number of IGMPv2 group membership reports received
  - Interface statistics Sent—Statistics for messages sent from this interface
    - v1 reports—Number of IGMPv1 leave group reports sent
    - v2 reports—Number of IGMPv2 leave group reports sent
    - leaves—Number of leave group membership messages sent
- Example

      host1#show ip igmp-proxy interface atm 3/0.2
      Interface atm3/0.2 address 21.1.1.1/255.0.0.0
      Administrative state enabled, Operational state enabled
      Interface parameters:
          Version 2
          State No v1 Router Present
          Unsolicited report interval 10 secs
          Version 1 router present timeout 400 secs
          0 multicast group
      Interface statistics:
          Rcvd:  0 v1 query, 6 v2 queries
                 0 v1 report, 0 v2 report
          Sent:  0 v1 report, 48 v2 reports, 0 leave
