forwarding command in EXEC mode.
show mpls forwarding [debug | detail | interface type instance | labels value | location | prefix
[network/mask | length] | private | summary | tunnels]
Syntax Description debug (Optional) Displays the failure reason if “?” is displayed in the “Byte
Switched” field of output. The typical reasons for failure to obtain statistics
include Communication Error b/w global and per-node forwarding process,
No such entry in per-node forwarding, and H/W stats error.
detail (Optional) Displays information in long form (includes length of
encapsulation, length of Media Access Control [MAC] string, maximum

and a slash between values is required as part of the notation.
–
rack: Chassis number of the rack.
–
slot: Physical slot number of the modular services card or line card.
–
module: Module number. A physical layer interface module
(PLIM) is always 0.
–
port: Physical port number of the interface.
Note In references to a Management Ethernet interface located on a route
processor card, the physical slot number is alphanumeric (RP0 or
RP1) and the module is CPU0.
Example: interface MgmtEth0/RP1/CPU0/0.
• Virtual interface instance. Number range varies depending on interface
type.
For more information about the syntax for the router, use the question mark
