Nexus 9300 + FEX

Решил побаловаться и подключить N2K-C2248TP-E свитч через FEX к моему N9K-C93180YC-EX

судя по документации

https://www.cisco.com/c/dam/en/us/td/docs/Website/datacenter/fexmatrix/fexmatrix.html

N9K-C93180YC-EX работает с N2K-C2248TP-E в режиме NX-OS

 

стоит NX-OS 9.3.3

 

смотрел на видео инструкцию - 

и все делал по ней. но не так все просто.

 

итак, настройки

install feature-set fex
feature-set fex

interface Ethernet1/47
  no shutdown

Eth1/47       --                 connected routed    full    10G     SFP-H10GB-CU2M

 

как видно порт поднят

show fex ничего не выводит.

 

далее, меняю настройки на порту 1/47

interface Ethernet1/47
  switchport
  switchport mode fex-fabric
  fex associate 101
  no shutdown

2020 Mar 18 14:27:28 93180YC-EX %FEX-5-FEX_PORT_STATUS_NOTI: Uplink-ID 0 of Fex 101 that is connected with Ethernet1/47 changed its status from Created to Configured

2020 Mar 18 14:27:29 93180YC-EX %ETHPORT-5-IF_TX_FLOW_CONTROL: Interface Ethernet1/47, operational Transmit Flow Control state changed to off
2020 Mar 18 14:27:29 93180YC-EX %ETHPORT-5-IF_DOWN_NONE: Interface Ethernet1/47 is down (None)

Eth1/47       --                 down      1         auto    auto    SFP-H10GB-CU2M

 

по команде show fex ничего не выводится. 

пытался переводить порт 1/47 в 10 гигабит принудительно - всё четно.

 

 

далее - я решил сделать подобную настройку через порт чанел

 

default  interface eth1/47

interface port-channel101
  switchport
  switchport mode fex-fabric
  fex associate 101

interface Ethernet1/47
  switchport
  switchport mode fex-fabric
  fex associate 101
  channel-group 101 mode active
  no shutdown

show fex
  FEX         FEX           FEX                       FEX

------------------------------------------------------------------------
---       --------             Connected   N2K-C2248TP-E-1GE   SSI155204GP

 

вроде что то заработало, но тут пусто

show fex 101
FEX 101 not found

 

и через некоторое время статус меняется с Connected  на offline

 

куда копать ?

победил, ошибка

вместо

  channel-group 101 mode active
нужно было указывать

Lacp не поддерживается на fex. Только статика
