Mirror Source Configuration

ingress-label
Syntax [no] ingress-label label [label ...up to 8 max]
no ingress-label label [label ...up to 8 max]
Context
debug>mirror-source
Description
This command enables ingress MPLS frame mirroring based on the top-of-stack MPLS label. Multi-
ple labels can be defined simultaneously.
The ingress-label command is used to mirror ingressing MPLS frames with specific MPLS labels to
a specific mirror destination. The ingress label must be at the top of the label stack and can only be
mirrored to a single mirror destination. If the same label is defined with multiple mirror destinations,
an error is generated and the original mirror destination remains.
The ingress-label mirror source overrides all other mirror source definitions. The MPLS frame is
mirrored to the mirror destination as it is received on the ingress network port. The 7750 SR MPLS
label space is global for the system. A specific label is mirrored to the mirror destination regardless of
the ingress interface.
By default, no ingress MPLS frames are mirrored. The ingress-label command must be executed to
start mirroring on a specific MPLS label.
The no ingress-label command removes all label mirroring for the mirror source. To stop mirroring
on specific labels, use the no ingress-label label form of the command. Multiple labels may be given
in a single no ingress-label command.
Default
No ingress MPLS labels for mirroring are defined.
Parameters
label — The top-of-stack label received on ingress to be mirrored. A label can only be mirrored to a
ip-filter
Syntax ip-filter ip-filter-id entry entry-id [entry-id ...]
no ip-filter ip-filter-id
no ip-filter ip-filter-id entry entry-id [entry-id ...]
Context
debug>mirror-source
Description
This command enables mirroring of packets that match specific entries in an existing IP filter.

single mirror destination.
If the label does not exist on any ingress network ports, no packets are mirrored for that label. An
error will not occur. Once the label exists on a network port, ingress mirroring commences for
that label.
Values
0 — 1048575. The local MPLS stack may not support portions of this range.
