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::3         ATM5/1.200      Include(1):
  2001::1
ff0e::4         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
--------------- --------------- --------------
ff0e::1         ATM5/1.200

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.
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
- 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:
    Version 2
    State No v1 Router Present
    Unsolicited report interval 100 (in 10ths of a second)
    5 multicast groups
Interface statistics:
    Rcvd: 0 v1 query, 0 v1 report, 25 v2 queries, 0 v2 report
    Sent: 0 v1 report, 0 v1 leave, 35 v2 reports

Example 2

host1#show ipv6 mld-proxy interface brief
