Tasks at a glance
(Optional.) Enabling the automatic report feature
(Optional.) Configuring the source MAC address of LLDP frames
(Required.) Advertising the LLDP management address
(Required.) Enabling the system to issue the generated ARP entry to a Layer 3 Ethernet subinterface after a
port receives an LLDP frame
Enabling DCN
After DCN is enabled, the device assigns an NE IP to the loopback interface with the largest interface
number and uses the interface for communication. The NE IP is specified as the management
address and advertised in an LLDP frame. For more information about LLDP, see
Layer 2—LAN
Switching Configuration Guide .
To enable DCN:
Step Command Remarks
1. Enter system view.
system-view N/A
2. Enable DCN and enter
DCN view.
dcn By default, DCN is disabled.
Configuring the NE ID and NE IP
Typically an NE automatically generates an NE IP according to its NE ID. The automatically
generated NE IP changes when the NE ID changes. When you replan your network or an NE ID
conflict occurs, you can manually configure the NE ID and NE IP. The manually configured NE IP
does not change when the NE ID changes.
To configure the NE ID and NE IP:
Step Command Remarks
1. Enter system view.
system-view N/A
2. Enter DCN view.
dcn N/A
3. Configure the NE ID.
ne-id id-number
By default, the NE ID is
automatically generated by using
the 24 low-order bits of the bridge
MAC address.
4. Configure the NE IP.
ne-ip ip-address { mask-length |
mask }
By default, the NE IP is
automatically generated by using
129 as the eight high-order bits and
the NE ID as the rest 16 bits. The
mask length is 32.
Configuring DCN VPN
Perform this task to ensure the independence of DCN services. For more information about VPN
instances, see
