Perfis GPON — OLT Datacom

Versão testada

DmOS 21.1 (DM4615 / DM4610). Compatível com DmOS 19.x+.

Os perfis GPON no DmOS definem o comportamento de banda, encapsulamento e serviços das ONUs.

Bandwidth-Profile (DBA)

O bandwidth-profile controla a alocação dinâmica de banda (DBA) no upstream.

Tipos de T-CONT

Tipo	Descrição
T-CONT 1	Fixed — banda fixa garantida
T-CONT 2	Assured — banda assegurada com burst
T-CONT 3	Non-Assured — banda não assegurada
T-CONT 4	Best-Effort — melhor esforço
T-CONT 5	Mixed — combinação de tipos

Criar Bandwidth-Profile

# T-CONT tipo 4 — Best Effort, 1 Gbps máximo
DM(config)# gpon
DM(config-gpon)# bandwidth-profile 10 name "1G-BE"
DM(config-gpon-bwprofile-10)# type best-effort maximum 1024000
DM(config-gpon-bwprofile-10)# exit

# T-CONT tipo 4 — 100 Mbps
DM(config-gpon)# bandwidth-profile 20 name "100M-BE"
DM(config-gpon-bwprofile-20)# type best-effort maximum 102400
DM(config-gpon-bwprofile-20)# exit

# T-CONT tipo 2 — Assured (garantido + burst)
DM(config-gpon)# bandwidth-profile 30 name "50M-ASSURED"
DM(config-gpon-bwprofile-30)# type assured assured 51200 maximum 102400
DM(config-gpon-bwprofile-30)# exit

# T-CONT tipo 1 — Fixed (VoIP)
DM(config-gpon)# bandwidth-profile 40 name "VOIP-FIXED"
DM(config-gpon-bwprofile-40)# type fixed fixed 2048
DM(config-gpon-bwprofile-40)# exit

Unidade: Kbps.

Line-Profile

O line-profile define os T-CONTs e GEM ports, e o mapeamento de VLANs.

Line-Profile Simples (1 VLAN)

DM(config-gpon)# line-profile 10 name "LP-INTERNET"
DM(config-gpon-lineprofile-10)# tcont 1 bandwidth-profile 10
DM(config-gpon-lineprofile-10)# gem-port 1 tcont 1
DM(config-gpon-lineprofile-10)# gem-port 1 vlan 100
DM(config-gpon-lineprofile-10)# exit

Line-Profile com Duas VLANs (Dados + VoIP)

DM(config-gpon)# line-profile 11 name "LP-DADOS-VOIP"
DM(config-gpon-lineprofile-11)# tcont 1 bandwidth-profile 10
DM(config-gpon-lineprofile-11)# gem-port 1 tcont 1
DM(config-gpon-lineprofile-11)# gem-port 1 vlan 10
DM(config-gpon-lineprofile-11)# tcont 2 bandwidth-profile 40
DM(config-gpon-lineprofile-11)# gem-port 2 tcont 2
DM(config-gpon-lineprofile-11)# gem-port 2 vlan 11
DM(config-gpon-lineprofile-11)# exit

Line-Profile Transparente (L2L)

DM(config-gpon)# line-profile 6 name "LP-L2L"
DM(config-gpon-lineprofile-6)# mapping-mode port
DM(config-gpon-lineprofile-6)# tcont 1 bandwidth-profile 10
DM(config-gpon-lineprofile-6)# gem-port 1 tcont 1
DM(config-gpon-lineprofile-6)# exit

Service-Profile

O service-profile define o número de portas ETH/POTS da ONU e o mapeamento de VLANs nas portas.

Service-Profile Padrão (4 ETH)

DM(config-gpon)# service-profile 10 name "SP-4ETH"
DM(config-gpon-srvprofile-10)# ont-port eth 4 pots 0
DM(config-gpon-srvprofile-10)# port vlan eth 1 100
DM(config-gpon-srvprofile-10)# port vlan eth 2 100
DM(config-gpon-srvprofile-10)# port vlan eth 3 100
DM(config-gpon-srvprofile-10)# port vlan eth 4 100
DM(config-gpon-srvprofile-10)# exit

Service-Profile com VoIP (4 ETH + 1 POTS)

DM(config-gpon)# service-profile 11 name "SP-4ETH-1POTS"
DM(config-gpon-srvprofile-11)# ont-port eth 4 pots 1
DM(config-gpon-srvprofile-11)# port vlan eth 1 10
DM(config-gpon-srvprofile-11)# port vlan eth 2 10
DM(config-gpon-srvprofile-11)# port vlan eth 3 10
DM(config-gpon-srvprofile-11)# port vlan eth 4 11
DM(config-gpon-srvprofile-11)# exit

Service-Profile Transparente

DM(config-gpon)# service-profile 6 name "SP-TRANSPARENTE"
DM(config-gpon-srvprofile-6)# ont-port eth 4 pots 0
DM(config-gpon-srvprofile-6)# port vlan eth 1 transparent
DM(config-gpon-srvprofile-6)# port vlan eth 2 transparent
DM(config-gpon-srvprofile-6)# port vlan eth 3 transparent
DM(config-gpon-srvprofile-6)# port vlan eth 4 transparent

RG-Profile (Residential Gateway)

O RG-Profile configura o roteador embutido na ONU (modo RG/router), habilitando PPPoE pass-through ou DHCP na WAN.

DM(config-gpon)# rg-profile 1 name "RG-PPPoE"
DM(config-gpon-rgprofile-1)# wan-connection pppoe
DM(config-gpon-rgprofile-1)# exit

DM(config-gpon)# rg-profile 2 name "RG-DHCP"
DM(config-gpon-rgprofile-2)# wan-connection dhcp
DM(config-gpon-rgprofile-2)# exit
