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 

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

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 JUNOSe Command Reference Guide, About This 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 JUNOSe Command Reference Guide, About This 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
