Monitoring PIM Interfaces for IPv6

Purpose

Display information about PIM interfaces. Specify no keywords or variables to view information about all PIM interfaces. You can specify the detail keyword to view detailed information for all PIM interfaces or for a specified PIM interface. You can specify the summary keyword to view the number of configured, enabled, and disabled PIM sparse-mode interfaces. You can specify the count keyword to view the number of multicast packets that the interface has sent and received.

Note: Provide an interface type and specifier (such as atm 3/0) to display information about that interface only. For details about interface types and specifiers, see Interface Types and Specifiers in JunosE Command Reference Guide.

Action

To display information for all PIM interfaces, or for a specified PIM interface:

host1# show ipv6 pim interface

PIM Interface Table
Interface Addr Interface   State Ver Mode    Nbr    Hello  J/P    DR    DR Addr   JoinFilter
                                             Count  Intvl  Intvl  Pri
101::1         ATM2/0.100  Up     2  Sparse   1      30    150     5    101::2    -
102::1         ATM2/0.101  Up     2  Sparse   1      30    100     2    102::2    silver
103::1         ATM3/0.102  Up     2  Sparse   1      30    100     2    103::1    gold

To display the number of configured, enabled, and disabled PIM sparse-mode interface:

host1#show ipv6 pim interface summary
PIM Interface Summary
  SM:    0, 0 enabled, 0 disabled

To display the number of multicast packets that the interface has sent and received:

host1#show ipv6 pim interface count
PIM Interface Count
Interface Addr  Interface Name       ControlPktCount In|Out
                                     Hello     JoinPrune  Assert
::107:84        ATM3/0.20             0         0           0
                                      0         0           0

Meaning

Table 81 lists the show ipv6 pim interface command output fields.
