Hello friends this article can be very useful for you. I will tell you about the configuration of VSOL GPON OLT, which I have been thinking about for a long time. So today's article is very easy on how we can configure VSOL GPON OLT step by step very easily. Earlier we learned how to configure VSOL EPON OLT. Today we will learn how to configure VSOL GPON OLT. Simply put, the configuration of EPON and GPON OLT is almost the same, but slightly different. So let's see what are the different configurations in VSOL GPON OLT.
OLT Access:
When a networking device is configured first we need to log into that device. The device cannot be configured without logging in. VSOL GPON OLT login can be done in 2 ways. One is AUX Port and the other is Console Port.
Accessing From AUX Port:
We can access our GPON OLT through the AUX port. It requires an Ethernet cable. Ethernet cable connectivity should be done from the AUX port of OLT to PC. After the connectivity is completed. An IP address should be set on the Ethernet port of the PC. The default IP of AUX Port in VSOL GPON OLT is 192.168.8.200. So we can use any IP address of that block on the Ethernet port of our PC. For example, I used 192.168.8.10 and the subnet is 255.255.255.0.
Now we can access VSOL GPON OLT through telnet or Web management. To access through web management, open any browser and then type https://192.168.8.200 in the search bar. If you want you can access OLT through Console Cable. We will configure OLT using AUX Port.
VSOL GPON OLT Deafult Info:
IP Address: 192.168.8.200
Username: admin
Password: Xpon@Olt9417#
Mainlink Configuration With VLAN:
If we want, we can do uplink configuration on all the giga ports except PON ports on our OLT. Our OLT has 8 GPON ports so we will do UPLINK configuration with 9 specific VLANs. So we will create VLAN from 500 - 508 and configure uplink on G9. Since we will pass multivlans through a port, our UPLINK Configuration is a Trunk.
Command:
Username: admin
Password: Xpon@Olt9417#
gpon-olt> ena
enable password: Xpon@Olt9417#
gpon-olt# configure terminal
gpon-olt(config)# vlan 500 - 508
gpon-olt(config)# exit
We have already created 9 VLANs. 8 is for 8-port GPON. Another one is for OLT remote management.
After creating the VLAN tag must be added. Since our uplink is G9 then this port needs to be configured. So let's configure.
gpon-olt(config)# interface gigabitethernet 0/9
gpon-olt(config-if-ge0/9)# switchport mode trunk
gpon-olt(config-if-ge0/9)# switchport trunk VLAN 500 - 508
gpon-olt(config-if-ge0/9)# exit
Assign IP Address For Remote Access MGT:
If we want to access our OLT from our LAN side, then we need to assign an IP address for remote access to any VLAN interface.
So let's assign an IP address to the interface of VLAN 500 through which we can remotely access our OLT.
Command:
gpon-olt(config)# interface vlan 500
gpon-olt(interface-vlan-500)# ip address 10.20.30.10 255.255.255.252
gpon-olt(interface-vlan-500)# exit
gpon-olt(config)# ip route 0.0.0.0/0 10.20.30.9 or 0.0.0.0 0.0.0.0 10.20.30.9
In our router, VLAN 500 is assigned to interface 10.20.30.9 and OLT's VLAN 500 is assigned to interface 10.2030.10. It is a private IP address. So we can now access our OLT from our local network.
Telnet Enable:
telnet is a protocol that provides a command line interface to remotely access a variety of devices such as server switches and routers.
By default, OLT access is turned off via Telnet from VSOL GPON OLT's firewall. It has to enable Telnet with manual permission. Follow the command below for Telnet Permission.
gpon-olt(config)# no login-access-list deny telnet 0.0.0.0 0.0.0.0
Now we can easily access our olt via telnet.
We have already configured our OLT now only the PON ports are left. So let's configure the PON ports.
Creating ONU Profile:
In this step, we will create a profile for ONU. ONU Profile needs to be created in all GPON OLTs. Now we will create a profile of 1 port ONU. So let's get started.
Command:
gpon-olt(config)# profile onu id 10 name xpononu
gpon-olt(profile-onu:10)# port-num eth 1
gpon-olt(profile-onu:10)# commit
gpon-olt(profile-onu:10)# exit
gpon-olt(config)# onu auto-learn default-onu-profile expon
We have configured the ONU profile here. I named the profile xpononu. You can give a name of your choice.
Creating DBA Profile:
Now we will create the DBA profile. DBA stands for Dynamic Bandwidth Allocation. This profile also needs to be created on each GPON OLT.
Command:
gpon-olt(config)# profile dba id 10 name dbaxpon
gpon-olt(config)# type 4 maximum 1024000
gpon-olt(config)# commit
gpon-olt(config)# exit
Creating service Profile:
In this step, we need to create a service profile for the PON port of OLT. Follow the below command to create a service profile.
Command:
gpon-olt(config)# profile srv id 10 name srv_pon1_vlan_501
gpon-olt(profile-srv:10)# portvlan eth 1 mode tag vlan 501
gpon-olt(profile-srv:10)# commit
gpon-olt(profile-srv:10)#exit
Creating Line Profile:
In this step, we will create a line profile and also create tcont and add tcont with the dba profile and vlan declare to the service port. Follow the below command to create a Line profile.
Command:
gpon-olt(config)# profile line id 10 name line_pon1_vlan_501
gpon-olt(profile-line:10)# tcont 1 name 1 dba dbagpon
gpon-olt(profile-line:10)# gemport 1 tcont 1 gemport_name 1
gpon-olt(profile-line:10)# service internet gemport 1 VLAN 501
gpon-olt(profile-line:10)# service-port 1 gemport 1 uservlan 501 VLAN 501
gpon-olt(profile-line:10)# commit
gpon-olt(profile-line:10)# exit
Bind Profile to PON port:
Our VSOL GPON OLT configuration is almost finished. And this is our last step. Now we will assign the line profile and service profile to our PON port. At the same time, ONU's auto-learn option must be enabled.
PON PORT 1:
gpon-olt(config)# interface gpon 0/1
gpon-olt(config-pon-0/1)# onu auto-learn
gpon-olt(config-pon-0/1)# onu auto-learn srv-profile name srv_pon1_vlan_501
gpon-olt(config-pon-0/1)# onu auto-learn line-profile name line_pon1_vlan_501
gpon-olt(config-pon-0/1)# exit
PON port 1 of our OLT is configured. Just like this, the service profile and line profile should be created for the rest of the ports and bound to each PON port.
Conclusion:
So friends, finally we successfully configured VSOL gpon OLT configuration step by step. Hope you can configure your OLT very soon. If you have any queries then comment, please. I will definitely support you for configure your olt. Thanks
