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
