Subject: [GTER] Drop de pacotes Cisco

Boa tarde a todos, temos um Switch Cisco Nexus 3064... Usamos uma LAG entre
um Datacom 4370 e esse switch, utilizando 2 portas de 10gb de cada
equipamento, porém identificamos que o Cisco está limitando o tráfego em
10gb, e notei também um drop de pacotes no Cisco, no Datacom nenhum drop,
troquei várias formas do Load-Balance da LAG, tanto no Datacom quanto no
Cisco, e sempre o Cisco dropa pacotes..
Verifiquei também a questão do MTU, o Datacom está usando o Jumbo Frames,
mas nesse modelo de Cisco, de acordo com o manual, diz que o modo Jumbo do
Cisco é feito através de QoS, e pode ser aí que está dropando... Alguém tem
alguma idéia ou alguma sugestão? Obrigado desde já...

Att.
