Table 50 show ip flow export Field Descriptions 

Field	Description
Exporting flows to 10.51.12.4 (9991) 10.1.97.50 (9111)	Specifies the export destinations and ports. The ports are in parentheses.
Exporting using source IP address 9.1.97.17	Specifies the source address or interface.

0 flows failed due to lack of export packet	No memory was available to create an export packet.
0 export packets were sent up to process level	The packet could not be processed by CEF or by fast switching, possibly because another feature requires running on the packet.
0 export packets were dropped due to no fib 0 export packets were dropped due to adjacency issues	Indicates that CEF was unable to switch the packet or forward it up to the process level.
0 export packets were dropped due to fragmentation failures 0 export packets were dropped due to encapsulation fixup failures	Indicates that the packet was dropped because of problems constructing the IP packet.
0 export packets were dropped enqueuing for the RP 0 export packets were dropped due to IPC rate limiting	Indicates that there was a problem transferring the export packet between the RP and the line card.
0 export packets were dropped due to output drops	Indicates that the send queue was full while the packet was being transmitted.

show ip mds forwarding

To display the Multicast Forwarding Information Base (MFIB) table and forwarding information for multicast distributed switching (MDS) on a line card, use the show ip mds forwarding command in user EXEC or privileged EXEC mode.

show ip mds forwarding [group-address] [source-address]

Syntax Description

group-address	(Optional) Address of the IP multicast group for which to display the MFIB table.

11.2(11)GS	This command was introduced.

Usage Guidelines

Use this command on the line card. This command displays the MFIB table, forwarding information, and related flags and counts.

---

Note To reach the console for a line card, enter attach slot# (slot number where the line card resides).

---

On a GSR only, line card commands can be executed from the RP using the following syntax: execute [slot slot-number | all] command.

The command argument is any of the line card show commands, such as show ip mds summary and show ip mds forward.

Examples

The following is sample output from the show ip mds forwarding command:

Router# show ip mds forwarding
