Basic MPLS commands
display mpls forwarding ilm
Use display mpls forwarding ilm to display Incoming Label Map (ILM) entries.
Syntax
In standalone mode:
display mpls forwarding ilm [ label ] [ slot slot-number ]
In IRF mode:
display mpls forwarding ilm [ label ] [ chassis chassis-number slot slot-number ]
Views
Any view
Predefined user roles
network-admin
network-operator
mdc-admin
mdc-operator
Parameters
label: Displays the ILM entry with the specified incoming label. The value range for this argument is 16
to 1048575. If you do not specify an incoming label, the command displays information about all ILM
entries on the specified card.
slot slot-number: Specifies a card by its slot number. (In standalone mode.)
chassis chassis-number slot slot-number: Specifies a card on an IRF member device. The chassis-number
argument specifies the ID of the IRF member device, and the slot-number argument specifies the number
of the slot that holds the card. (In IRF mode.)
Usage guidelines
An ILM entry records the label operation type, outgoing label, and other forwarding information.
After an LSR receives a labeled packet, it does the following:
1. Identifies the ILM entry that matches the top label of the packet.
2. Performs the specified label operation.
3. Forwards the packet.
Examples
# Display the ILM entry with incoming label 30.
<Sysname> display mpls forwarding ilm 30
Flags: T - Forwarded through a tunnel
N - Forwarded through the outgoing interface to the nexthop IP address
B - Backup forwarding information

Flag
Forwarding flag:
•T—Forwarded through a tunnel.
•N—Forwarded through the outgoing interface to the next hop IP address.
•B—Backup forwarding information.
•A—Active forwarding information.
SwapLabel Outgoing label value.
Forwarding Info
Forwarding information:
•When the forwarding flag is N, the forwarding information records the
outgoing interface and the next hop.
•When the forwarding flag is T, the forwarding information records the NID.
display mpls forwarding nhlfe
Use display mpls forwarding nhlfe to display Next Hop Label Forwarding Entry (NHLFE) entries.

Parameters
nid: Displays the NHLFE entry with the specified NID. The NID value range is 0 to 4294967294. If you
do not specify an NID, the command displays information about all NHLFE entries on the specified card.
slot slot-number: Displays the NHLFE entries on a card. The slot-number argument specifies the number
of the slot that holds the card. (In standalone mode.)
chassis chassis-number slot slot-number: Displays the NHLFE entries of a card on an IRF member device.
The chassis-number argument specifies the ID of the IRF member device. The slot-number argument
specifies the number of the slot that holds the card. (In IRF mode.)
Usage guidelines
An NHLFE entry records label forwarding information, such as the outgoing label and outgoing interface.
NHLFE entries are mainly used to add multiple labels to packets.
To add multiple labels to a packet, an LSR does the following:
1. Obtains the bottom label and NID in the matching FIB or ILM entry.
2. Obtains the outer label in the NHLFE entry identified by the NID.
Examples
# Display the NHLFE entry with NID 2048.
<Sysname> display mpls forwarding nhlfe 2048
Flags: T - Forwarded through a tunnel
N - Forwarded through the outgoing interface to the nexthop IP address

Parameters
nid-value1: Specifies an NID in the range of 0 to 65535. If used with the nid-value2 argument, the
nid-value1 argument represents the start NID of an NID range.
to nid-value2: Specifies the end NID of the NID range. The value range for the end NID is 0 to 65535.
If you specify an NID range by using the nid-value1 argument and the to nid-value2 option, the

Usage guidelines
NIDs are 32-bit binary numbers. They include fixed NIDs and dynamic NIDs.
•Fixed NIDs—Generated for tunnel interfaces. The highest four bits are a value other than 0000.
•Dynamic NIDs—NIDs except fixed NIDs. The highest four bits are 0s.
If you do not specify any parameters, the command displays usage information for all dynamic NIDs.
