perda de pacotes entre nós

lincoln rattes · ‎04-28-2016

Prezados estou com o seguinte problema:

Tenho alguns clusters que estão perdendo pacote entre nós. uso N2K2232TM e N2K-C2248TP. Estão usando bound com duas interfaces eth0 e eth1.

Testes

10.29.227.47 source ----> destination 10.29.227.160

: olhando o tcp dump vimos que os pacotes saíam da máquina 10.29.227.47

chegavam na eth0 da 10.29.227.160

10.29.227.160 respondia pela eth1

mas o pacote não chega na 10.29.227.47

arquitetura

10.29.227.160

(eth0)N5K - A & (eth1) N5K - B

Estão perdendo quantos %?

Veja a configuração dos port-channel. mande um show port-channel summary nos dois 5k.

Envie também um show interface X switchport e show interface trunk "caso seja trunk".

Estão em VPC?

Caso já tenha resolvido, informe a solução.

Marcelo,

Segue o port-channel do N5K-B. A configuração é a mesma para o N5K-A.
