Output Fields
Table 1 describes
the output fields for the show pim mdt command. Output
fields are listed in the approximate order in which they appear.
Field Name |
Field Description |
Level of Output |
|---|---|---|
Instance |
Name of the routing instance. |
All levels |
Tunnel direction |
Direction the tunnel faces, from the router's perspective: Outgoing or Incoming. |
All levels |
Tunnel mode |
Mode the tunnel is operating in: PIM-SSM or PIM-ASM. |
All levels |
Default group address |
Default multicast group address using this tunnel. |
All levels |
Default source address |
Default multicast source address using this tunnel. |
All levels |
Default tunnel interface |
Default multicast tunnel interface. |
All levels |
Default tunnel source |
Address used as the source address for outgoing PIM control messages. |
All levels |
C-Group |
Customer-facing multicast group address using this tunnel. If you enable dynamic reuse of data MDT group addresses, more than one group address can use the same data MDT. |
detail |
C-Source |
IP address of the multicast source in the customer's address space. If you enable dynamic reuse of data MDT group addresses, more than one source address can use the same data MDT. |
detail |
P-Group |
Service provider-facing multicast group address using this tunnel. |
detail |
Data tunnel interface |
Multicast data tunnel interface that set up the data-MDT tunnel. |
detail |
Last known forwarding rate |
Last known rate, in kilobits per second, at which the tunnel was forwarding traffic. |
detail |
Configured threshold rate |
Rate, in kilobits per second, above which a data-MDT tunnel is created and below which it is deleted. |
detail |
Tunnel uptime |
Time that this data-MDT tunnel has existed. The format is hours:minutes:seconds. |
detail |
Sample Output
