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
