Comandos para os switches IBM ATM modelo 8265

Todos os comandos virão sempre em pares. Um fazendo a configuração e outro confirmando-a.

Designação do endereço ATM do switch:

CBPF>
CBPF> set pnni node:0 atm_address:47.2.3.4.5.6.7.8.9.10.11.12.01.14.15.16.17.18.19.0
Set request executed.
Issue COMMIT PNNI to activate if this is your final 'SET PNNI' entry.
Issue UNCOMMIT PNNI to cancel, removes all 'set pnni' since last COMMIT PNNI.
CBPF>
CBPF> commit pnni * para salvar o que foi feito.*
COMMIT execution will first SAVE pnni configuration updates then RESET Hub..
Are you sure ? (Y/N) Y
CBPF>

Obs.: para cada switch teremos um endereço ATM diferente.

Comandos para o switch IBM ATM modelo 8271

Em virtude de o equipamento não ser operado via linha de comando, apresentaremos
o passo a passo do menu de opções.

1. Non-Ethernet Ports Menu...
2. Configure ATM Port Parameters...
3. User-Network Interface (UNI) Level
4. Save and Return
5. Configure LAN Emulation Client (LEC)...
6. Quick Config
7. Enable
8. Reset

**** falta colocar alguma coisa ensinando a mexer nos contextos
(designar portas, IP do LEC, nome do contexto)

Conclusões

Neste ítem será mostrada a tabela do LES do 8265, contendo os seus clientes (LECs).
Também será mostrada a lista de LECs presentes no switch 8271.
