Configure Q-in-Q Lscable ONT

January 2, 2016March 14, 2012 by Shahed Israr

Configure Q-in-Q Lscable ONT:

Today i will show you how to configure q-in-q Ls cable ONT. Here i use ONT Ethernet port 1 to configure q-in-q. So let’s go to our configuration part. [boxads]

Here step 1 to 3 & 5 to 8 are same as How to register Ls Cable ONT. We change only step 4 for q-in-q configuration. Bellow pink color line is for q-in-q.

Step-4: Now need to create a profile with VLAN & assign Bandwidth.

Ls-OLT#config t
Ls-OLT(config)#gpon-omch
Ls-OLT(config-gpon)#profile onu Profile_Name
Ls-OLT(config-gpon-prof Profile_Name)#vlan-oper 1 qnq untagging 100
Ls-OLT(config-gpon-prof Profile_Name)#vlan-oper 2-4 tagging untagging 333
Ls-OLT(config-gpon-prof Profile_Name)#rate-limit-up 1 1024
Ls-OLT(config-gpon-prof Profile_Name)#rate-limit-down 1 1024
Ls-OLT(config-gpon-prof Profile_Name)#exit

Configure Q-in-Q Lscable ONU

January 2, 2016March 14, 2012 by Shahed Israr

Configure Q-in-Q Lscable ONU:

Today i will show you how to configure q-in-q lscable onu Ethernet port, here i use ONU Ethernet port 1 to configure q-in-q. So let’s go to our configuration part. [boxads]

Step-1: Login your LS cable ONU device & go to config mode & type bellow command, like this……….

interface fe1
   switchport access vlan 100
   switchport vlan-stacking customer-edge-port
   rate-limit input rate 1024 burst 16000
   rate-limit output rate 1024 burst 16000
   duplex full

N.B: here 100 is q-in-q Vlan

BGP update source loopback0 commands

February 11, 2015March 10, 2012 by Shahed Israr

BGP update source loopback0:

[boxads]Today i will discuss why we use BGP update source loopback0 for establishing neighbor relationship between bgp peering. If we have two paths between BGP neighbors, then which path use to establish neighbor relationship? don’t worry i will describe you briefly, please look bellow diagram:

In this topology we see that there are two links between router R1 and router R2. We can establish two neighbor relationships, on both paths, but this is not a good solution. So, we’ll establish only one neighbor ship with each other. BGP gives us an option to change the source of packets sent. In this case we can use Loopback interface as source of BGP packets sent between these neighbors. By using a loopback interface as source interface we have two paths between them, if one of paths fails, the other one will be used.

Configure Trunk port Huawei ONT

How to Configure Trunk port Huawei ONT

Today i will show how to configure trunk port Huawei ONT. Here i use Huawei MA5608T series OLT & EchoLife:HG851 ONT device. We will configure Trunk port eth-port: 1 of that ONT. So let’s start our configuration part…………….

Step-1: At first we search ONT serial number in our OLT discover list option by bellow command:

enable
config t
display ont autofind all

Look like bellow format in OLT:

Huawei-OLT>enable
Huawei-OLT#config
Huawei-OLT(config)#display ont autofind all

—————————————————————————-

Number              : 1

Ont EquipmentID      : EchoLife:HG851
Ont autofind time    : 2014-09-27 04:10:07+06:00
—————————————————————————-
The number of GPON autofind ONT is 1

Register Ls Cable ONT / Configure Lscable ONT

January 2, 2016February 27, 2012 by Shahed Israr

How to Register Ls Cable ONT:

[boxads]Today i will discuss how to configure / Register LS Cable ONT in LsCable OLT. Here i use LST20016 OLT. At first login your OLT & follow bellow step.

Step-1: Find ONT serial in your discovery list.

Ls-OLT>en
Ls-OLT#sh gpon onu discover-list

Step-2: If find your ONT discover list then need to register it.

Ls-OLT#config t
Ls-OLT(config)#gpon-omch
Ls-OLT(config-gpon)#onu register 8/1 5 LSED10030174

[N.B:8/1=PON interface, 5=ONT]

Step-3: Now add description of that ONT.

Ls-OLT(config-gpon)#onu describe 8/1 5 Desc_Name
