Number of ONT Ethernet ports has reached the maximum of the PON port

Failure: The number of ONT Ethernet ports has reached the maximum of the PON port

ONT add time OLT showing one error “The number of ONT Ethernet ports has reached the maximum of the PON port”. This issue only occurred when add ONT at PON port 0/1/2 , others PON port is normal when we add ONT. [boxads]

Below are the example error :

Gponsolution_OLT(config-if-gpon-0/1)#ont add 2 sn-auth 4857544xxx0A1042D omci ont-lineprofile-id 1 ont-srvprofile-id 1
{ <cr>|desc<K>|ont-type<K> }:

Command:
ont add 2 sn-auth 4857544xxx0A1042D omci ont-lineprofile-id 1 ont-srvprofile-id 1
Failure: The number of ONT Ethernet ports has reached the maximum of the PON port

ONT Ethernet ports has reached the maximum of the PON port
ONT Ethernet ports has reached the maximum of the PON port

Solution

  • Step 1 : Check OLT and Service Board type/Model. (Note:Most service board support 128 ONT in one PON port and as default ONT max eth port is 8.
  • Step 2 : Check OLT configuration under ont-srvprofile id 1 because the error shown when adding ONT at PON port 1 ont-srvprofile id 1.
ont-srvprofile gpon profile-id 1 profile-name "FTTH"
  ont-port pots adaptive 32 eth adaptive 24
  commit
  • Step 3 : Check on the PON port 2 how many ONT is added.
    • After check ‘display ont info 2 all’ from gpon mode, we see 42 ONTs are added this PON port.
    • Based on service board specification, max value of ETH port can support by 128 ONTs is 1024 eth port  (128 x 8 =1024).
    • Based on calculation for customer current total of ETH port value, is 1008 (42 ONTs x 24 eth  = 1008)
    • So when client try to add ONT 43 , the error generated because ETH port value 1008 + 24= 1032. Which this value already exceed the maximum value of maximum 1024.
  • Step 4 : Change the the configuration on ont-srvprofile id 1, from ont-port eth adaptive 24 to ont-port eth adaptive 4 to fully utilized the number of ETH port without any waste.
ont-srvprofile gpon profile-id 1 profile-name "FTTH"
  ont-port pots adaptive 2 eth adaptive 4
  port vlan eth 1 translation 309 user-vlan 309
  port vlan eth 2 translation 309 user-vlan 309
  port vlan eth 3 translation 309 user-vlan 309
  port vlan eth 4 translation 309 user-vlan 309
  commit
  • Step 5 : After change ont-srvprofile value, the 43 number ONT we can add normally. [bodyads]
