Option
Intervals
Experimental bits
Verbose
MPLS LSP Ping options described in the table above can be implemented by using the following syntax:
ping mpls
{ipv4 destination-address destination-mask [destination address-start address-end increment]
[ttl time-to-live] | pseudowire ipv4-address
vc-id vc-id
[destination address-start address-end increment] | traffic-eng tunnel-interface
tunnel-number
[ttl time-to-live]}
[source source-address] [repeat count]
[{size packet-size} | {sweep minimum maximum size-Increment}]
[pad pattern]
[timeout seconds] [intervalmsec]
[exp exp-bits] [verbose
MPLS LSP Traceroute options described in the table below can be implemented by the use of the following
syntax:
trace mpls
{ipv4 destination-address destination-mask
[destination address-start address-end address-increment] | traffic-eng tunnel-interface
tunnel-number}
[source source-address] [timeout seconds]
[ttl maximum-time-to-live]

MPLS LSP Ping, Traceroute, and AToM VCCV
Description
A parameter you can specify to set the time in
milliseconds between successive MPLS echo requests.
The default is 0.
Set with the interval msec keyword and argument.
Three experimental bits in an MPLS header used to
specify precedence for the MPLS echo reply. (The
bits are commonly called EXP bits.) The range is
from 0 to 7, and the default is 0.
Specify with the exp exp-bits keyword and argument.
For use with the MPLS LSP Ping and Traceroute
features.
Option that provides additional information for the
MPLS echo reply--source address and return codes.
For the MPLS LSP Ping feature, this option is
implemented with the verbose keyword.
For use with the MPLS LSP Ping feature only.
