# Monitoring MLD Proxy

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

show ipv6 mld-proxy

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

      host1#show ipv6 mld-proxy
      Routing Process MLD Proxy, Administrative state enabled, Operational state
      enabled
          total 1 upstream interface, state enabled
          1 multicast group

- See show ipv6 mld-proxy.

show ipv6 mld-proxy groups

- Use to display information about multicast groups that MLD proxy reported.
- Field descriptions
  - Grp Address—Address of the multicast group
  - Interface—Type and identifier of the upstream interface associated with the multicast group
  - Grp Mode
    - Blank—No sources included or excluded for this group
    - Include—Sources included for this group
    - Exclude—Sources excluded for this group
  - Count—Total number of multicast groups associated with this interface
- Example 1

      host1#show ipv6 mld-proxy groups

      Grp Address     Interface       Grp Mode
      --------------- --------------- --------------
      ff0e::1         ATM5/1.200
      ff0e::2         ATM5/1.200

      ff0e::5         ATM5/1.200      Exclude(1):
        2001::2

      Counts: 3 <*,G>, 1 Exclude (1 sources), 1 Include (1 sources)
             (5 total)

- Example 2

      host1#show ipv6 mld-proxy groups ff0e::1
      Grp Address     Interface       Grp Mode
      --------------- --------------- --------------

      Counts: 1 <*,G>
             (1 total)

- Example 3

      host1#show ipv6 mld-proxy groups count
      Counts: 3 <*,G>, 1 Exclude (1 sources), 1 Include (1 sources)
             (5 total)

- See show ipv6 mld-proxy groups.

show ipv6 mld-proxy interface

- Use to display information about the interface on which you configured MLD 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 option 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—MLD version on this interface
  - State—Presence of MLDv1 routers on the same subnet as this upstream interface
  - Unsolicited report interval—Time interval at which this upstream interface sends unsolicited group membership report
  - 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 MLDv1 multicast listener queries received
    - v1 report—Number of MLDv1 multicast listener reports received
    - v2 queries—Number of MLDv2 multicast listener queries received
    - v2 report—Number of MLDv2 multicast listener reports received
  - Interface statistics Sent—Statistics for messages sent from this interface
    - v1 reports—Number of MLDv1 multicast listener reports sent
    - v1 leaves—Number of multicast listener done messages sent
    - v2 reports—Number of MLDv2 multicast listener reports sent
- Example 1

      host1#show ipv6 mld-proxy interface

      Interface ATM5/1.200 address fe80::f7:0:231a:0
      Administrative state enabled, Operational state enabled
      Interface parameters:
