keyword is specified, the following additional information is displayed:
detail
• Outgoing port number
• Counts of packets and bytes that have been transmitted using the database entry
By default, information is displayed for active mappings. To display information for
liberally-retained inactive mappings, use the inactive keyword. An inactive mapping is
a mapping that was received from an LDP peer, but is not being used to reach the
associated FEC. Using the
keyword causes inactive mappings to be displayed.
inactive
The inactive keyword does not apply to RSVP-TE LSPs, because RSVP-TE operates in
downstream-on-demand mode.
Displaying MPLS Label Mapping Information
To display MPLS label mapping information, use the following command:
show mpls label {summary | {<label_number>} | fec [host <ipaddress> |
prefix <ipaddress/masklength>]} {detail}}
This command displays information from the Incoming Label Map (ILM), which is used
when forwarding packets that arrive labeled as MPLS packets.
When the
parameter is omitted, summary information is displayed for
label_number
all incoming label assignments that have been made by the switch. When the
is specified, summary information is displayed for the label.
label_number
Use the
keyword to display the label associated with an FEC. You can specify both
fec
host and prefix FEC types. The
keyword displays the number of labels
summary
allocated from each label range partition.
By default, the information displayed includes:
• Next hop IP address
• Outgoing and incoming labels
