Switches Nortel funcionam com placas Intel (entre
outras) em "Fast EtherChannel", ou o nome que voce queira dar....
A cisco nao foi a primeira a oferecer a
facilidade, por sinal :-)
As tecnologias de
"agregacao de banda" tem alguns detalhes..
1- A velocidade "final" continua a mesma, um pacote
vai continuar levando o mesmo tempo para passar pelo link, o que aumenta � o
"tamanho da via" (mais pacotes podem ser enviados ao mesmo tempo em 100 ou
1000 Mbps)
2- O numero de links possiveis em um trunk depende
do fornecedor, pode ser de 2 a 8 links, portanto de 200Mbps ate' 8Gbps (8
trunks de 1000Mbps).
3- Diferentes algoritmos para a distribuicao sao
usados dependendo do fornecedor, ou mesmo do produto especifico do fornecedor.
Alguns fazem um hash do endereco origem e destino "layer 2", enquanto outros
usam o layer 3, por exemplo.

Qual placa dual vc est� usando. Se for uma Server
Intel, existem tr�s op��es:
Adapter Fault Tolerance (AFT) - Faz com que as duas placas
funcionem de modo que, se uma cair, a outra assume.
Adapter Load Balancing (ALB) -
Aumenta o throughput. Ou seja, a entrada continua sendo a 100, mas a sa�da a
200. Qualquer switch 100TX suporta.
Fast EtherChannel (FEC) - Entrada e sa�da a 200
Mbps. Por essa tecnologia ser da Cisco, s� os switches dela a
suportam

- http://www.networkdesigners.com.br Dicas: - o PathRouter nao passava
alguns parametros SNMP de forma adequada para o cfgmaker, vc pode rodar o
cfgmaker e ter que ajustar alguns parametros. Um exemplo que eu sei que
acontecia eh vc ter uma linha diferente de 64kbps. O PathRouter sempre
passava 64Kbps para o cfgmaker (pque o clock esta como externo e nao tinha
entrada para bandwidth. Agora tem, mas nao sei se passa isso para o SNMP, o
devepment team deles estavam fazendo boas alteracoes na mib do PathRouter
nas ultimas versoes. Consulte o suporte tecnico para verificar se estas
alteracoes foram feitas... mas mesmo que isso funcione, isso nao impede que
vc faca um ajuste manual no .cfg. - nao sei se vc sabe, mas o SNMP do
PathRouter eh (era?) disable por default. Habilite a community. - teste o
SNMP do PathRouter antes com um aplicativo tipo "snmpwalk" ou "snmpget". Se
funcionar entao eh soh passar para o .cfg e ajustar. Senao, tem que mexer
com a comunicacao entre o router e o Linux. - instalacao do mrtg tem
milhares de dicas... veja na pagina da Linux-BR, na pagina do proprio
mrtg... []s Edgar -----Original Message----- From: Flavio Alberto
