Eu tenho dois switches Dell PowerConnect 5424, com o firmware atual instalado. Eu estou tentando configurar um grupo LAG, que ligará os dois switches para um determinado número de portas (8-16) em cada switch. Mas não tendo muito sucesso.
Não importa o que eu tente, não consigo fazer ping de um host no switch 2, de um host no switch 1. Eu incluí os bits relevantes da minha configuração abaixo.
Qualquer ajuda seria muito apreciada.
Em caso de relevância, as portas 1-7 já estão em uso para uma SAN diferente (e EMC) que possui sub-redes separadas para cada comutador, portanto, nenhum LAG é necessário. Eu tenho aqueles portos marcados como 'switchport access vlan 2'
- Eu preciso de portas (8-16) em cada switch para serem vinculadas a um LAG (LAG 3).
- Os hosts nessas portas estão na mesma sub-rede
-
Os hosts transmitirão tráfego não marcado (hosts / matrizes de array Equallogic)
-
Quatro portas (20-23) em cada switch estão no grupo LAG
- Cada uma dessas quatro portas está conectada às portas correspondentes em outro switch
-
O encaminhamento de tráfego das portas 8-16 para o equivalente em outro switch.
-
Eu tentei várias permutações de modos gerais / troncos / de acesso
Configuração parcial

flowcontrol on

Detalhes da Spanning Tree depois que eu a desativei !! Eu presumo que os pacotes BPDU de 1,2 milhões são o que causou meus problemas!
