MINI-Link TN
DCN Configuration Via CLI
BY: Khalil Al-alami
First: IP address configuration: {Basic NE}
Note: First must configure default gateway IP address as bellow
› CMD>telnet current IP address {example 192.168.1.1 if not configured yet}
Ex. Site 180
› CMD>telnet 192.168.1.1 {login to the NE CLI}
Password: ******** {“ericsson” all small letter}
› TN-180>en
{enable privilege mode}
Password: ******** {“ericsson” its control_user password}
› TN-180#
› First CHANGE IP GATEWAY OF NE
› TN-180#config {enable configuration mode}
› TN-180 (config) #ip route 0.0.0.0/0 10.205.16.161 {GW: 10.205.16.161}
› TN-180 (config) #exit
› TN-180#write {save configuration}

Second: change IP and subnet mask of NE:
o{IP: 10.205.16.163/28}
› TN-180#config
› TN-180#(config) #ip address 10.205.16.163 255.255.255.240
› TN-180#(config) #exit
› TN-180#write
› TN-180#sh ip route {view the configuration}
 The NE will auto disconnected because the IP changed
Connection closed by foreign host.
IDLE_TIMEOUT timer restarted
Here you have to re-login to the NE by the new IP and enter to privilege mode and do
“write” command. Else the old IP with be recovered after some time (confirmation
timer).
› CMD>telnet 10.205.16.163 {new configured IP}
› TN-180>en
Password: ******** {ericsson}
› TN-180#
› TN-180#write {Save the new configuration}
› TN-180#show ip route {use this to view the configuration done}

Third: LAN-DCN interface configuration:
The interface ID depends of AMM model as below:
TN 6P: 1/7/2 lan-dcn
TN 20P: 1/11/7 lan-dcn
CN-510: 1/1/8 lan-dcn
By CLI you can show the TN (AMM) by the below command:
› TN-180#sh subrack 1
Or directly you can check the lan id by below command:
› TN-180#show interface ethernet-eps
From the output result find the lan-dcn interface and what is the ID? But if you
don’t find it that means this interface configured as “front connector”.
Khalil Al-Alami | Page 4
In this case you need to used the below commands to
activate this interface:
› TN-180#config
› TN-180 (config) #dcn-mode disable
› TN-180 (config) #dcn-mode vlan
› TN-180 (config) #exit
› TN-180#write
Now you can use the command
› TN-180#sh interface ethernet-eps 1/7/2 lan-dcn {show DCN}
no usage
ifName “1/7/2”
This means the LAN-DCN “unused”
› TN-180#sh interface ethernet-eps 1/7/2 lan {show LAN}
› TN-180#sh interface ethernet-eps {to show all}

lan-dcn port configuration:
› TN-180#config
› TN-180 (config) #interface ethernet-eps 1/7/2 lan-dcn
› TN-180 (config-eth)#usage bridge-port 3
› TN-180 (config-eth)#exit
› TN-180 (config)#exit
› TN-180#write
› TN-180#config
› TN-180 (config)#bridge-port 3
› TN-180 (config-bridgeport)#role cnp
› TN-180 (config-bridgeport)#exit
› TN-180 (config)#exit
› TN-180#write
Khalil Al-Alami | Page 6
› TN-180#sh interface ethernet-eps 1/7/2 lan-dcn
usage bridge-port 3
ifName "1/7/2“
Khalil Al-Alami | Page 7
Now to configure the VLAN:
› TN-180#config
› TN-180 (config) #sh vlan {to show the current Vlan config}
› TN-180 (config) #vlan 600 DCN-VLAN {create Vlan 600 with Name
DCN-VLAN}
› TN-180 (config-vlan) #egressports 2,3 {ports member setup}
› TN-180 (config-vlan) #untagged-ports 3 {untagged DCN port}
› TN-180 (config-vlan) #exit
› TN-180 (config) #exit
› TN-180#write {always save configuration}
› TN-180#sh vlan {to view configured Vlan}

Why need to know CLI???
Example:
During integration for the site 244202:
› Topology: 244202244412244410
› Without correct DCN configuration its possible to remotely login from
244202 to 244412 only but to 244410 was not possible because the
DCN configuration for 244202 was incomplete.
› 244202 -SVLAN=301 and DCN-Vlan=606. although 301 are configured
on both 244412 and 244410 but the port egress was not completed at
244410, I discovered that when I configured the dcn-vlan (606) at both
244412 by GUI and at 244410 by CLI.
