Description
For passive monitoring on ATM, SONET/SDH, Fast Ethernet, and Gigabit Ethernet
interfaces only, specify the number of MPLS labels an incoming packet must have for
the pop-all-labels statement to take effect.
For passive monitoring on the MX304 router, MX
Series routers with MPCs, and MX series routers with the LC9600 line card, all
labels are popped by default and the required-depth statement is
ignored.
If you include the required-depth 1 statement, the
pop-all-labels statement takes effect for incoming packets with
one label only. If you include the required-depth 2 statement, the
pop-all-labels statement takes effect for incoming packets with
two labels only.
Options
number—Number
of MPLS labels on incoming IP packets.
Range: 1 through 2 labels.
Default: If you omit this statement, the
pop-all-labelsstatement takes effect for incoming packets with one or two labels. The default is equivalent to including therequired-depth [ 1 2 ]statement.
Required Privilege Level
