Добрый день

есть потребность физически завернуть траффик на порту данного коммутора.

Схема следующая - от источника траффик идет в порт коммутатора (например в порт 29), далее прокидывается Vlan на порт 30, в котором установлен трансивер с физической петлей.

На текущий момент не могу добиться прохождения трафика


---------------------------------------------------------------------------
Port            Description        Intvl    Rx Mbps  Rx %     Tx Mbps  Tx %

Ethernet1/29    N/A                30/30    49148.6  49.1%    0.0      0.0%
Ethernet1/30    N/A                30/30    0.0      0.0%     0.0      0.0%

отключить MAC-LEARN не получается

nexus(config)# mac-learn disable
config not supported on platform

 

отключение mac address-table notification mac-move тоже не приводит к результату

можно еще что то сделать?

 

настройки коммутатора общие:

Может я не правильно понял, но если про зеркало то у нас так: 

interface Ethernet1/46
  switchport mode trunk
  switchport monitor
  switchport trunk allowed vlan none

По крайней мере, изучение мак-адресов при мониторе отключается

при установке в монитор, изучение mac действительно, отключается, но траффик все равно не собирается.
