Hello, everyone!
Today, I want to start to explain the GPON ONU basic operations. Now, in this article, I will explain the service profile. Let’s get started.
As I said in the previous articles, GPON ONU profiles have 4 profiles:
DBA profile,
Line profile,
Service profile, and
SNMP profile.
These parameters need to be configured for the GPON access service.
The service profile is used to define ONU type, ONU interface number, VLAN mapping, multicast VLAN, etc.
OMCI management mode is used for ONT, while for MDU it does not need to be configured with a service profile.
The command to display the current profile is as follows:
TEST(config)#display ont-srvprofile gpon all
{ <cr>||<K> }:
Command:
display ont-srvprofile gpon all
-----------------------------------------------------------------------------
Profile-ID Profile-name Binding times
-----------------------------------------------------------------------------
0 srv-profile_default_0 0
10 8012 465
20 ftth 542
-----------------------------------------------------------------------------
Total: 3
Service profile-id 0 is the default service profile. Service profile-id 10 and service profile-id 20 are configured additionally because we have such types of ONUs in the system.
When configuring the service profile, if we do not enter the ID, the system will automatically assign the ID as with the line profile.
The command to create a service profile is as follows:
TEST(config)#ont-srvprofile gpon profile-id 25 profile-name EG8247Q
With this command, we have created a new service profile with ID 25 and the name EG8247Q.
The next step in the configuration is to define the ports and their number. This is a mandatory command. We achieve this with the following command:
TEST(config-gpon-srvprofile-25)#ont-port eth 4 pots 2 catv 1
{ <cr>|moca<K>|tdm<K>|tdm-srvtype<K>|tdm-type<K>|vdsl<K>|wifi<K> }:
Command:
ont-port eth 4 pots 2 catv 1
As we can see, this type of ONT has 4 ethernet ports, 2 POTS, and 1 CATV port.
The port VLAN command is used to configure the VLAN to ONU. Used with bridge ONTs.
TEST(config-gpon-srvprofile-15)#port vlan eth 1 translation 701 user-vlan 701
When we have multicast services in the system, the VLAN tag forwarding mode is configured. The following command is used for this:
TEST(config-gpon-srvprofile-15)#multicast-forwarding untag
The following command is used when configuring the IGMP packet forwarding mode (multicast services in the system).
TEST(config-gpon-srvprofile-15)#igmp-forward unconcern
Finally, we need to confirm the configuration and leave the service profile. The following commands are used for this:
TEST(config-gpon-srvprofile-25)#commit
TEST(config-gpon-srvprofile-25)#quit
This is the end of service profile configuration. There is a small difference between bridge ONT and gateway ONT.
After this configuration, with the next command, we can see all service profiles on the system:
TEST(config)#display ont-srvprofile gpon all
{ <cr>||<K> }:
Command:
display ont-srvprofile gpon all
-----------------------------------------------------------------------------
Profile-ID Profile-name Binding times
-----------------------------------------------------------------------------
0 srv-profile_default_0 0
10 8012 465
25 EG8247Q 0
20 ftth 542
-----------------------------------------------------------------------------
Total: 4
Now, we can see a new service profile with ID 25 and the name EG8247Q.
For more information about service profile with ID 25 and name EG8247Q, we can use the next command:
TEST(config)#display ont-srvprofile gpon profile-name EG8247Q
{ <cr>||<K> }:
Command:
display ont-srvprofile gpon profile-name EG8247Q
-----------------------------------------------------------------------------
Profile-ID : 25
Profile-name: EG8247Q
Access-type : GPON
-----------------------------------------------------------------------------
Port-type Port-number Max-adaptive-number
-----------------------------------------------------------------------------
POTS 2 -
ETH 4 -
VDSL 0 -
TDM 0 -
MOCA 0 -
CATV 1 -
-----------------------------------------------------------------------------
…
The next command is a command for deleting the service profile. We can use profile-id or profile-name.
TEST(config)#undo ont-srvprofile gpon profile-id 25
This is the end of this article. In the next article, I will continue to write about this topic >> GPON ONU basic operations (5): SNMP profile.
Thank you!
