Добрый день.
при настройке MIRRORING на SNR возника проблема с тем, что при мирроринге TX направления в vlan нет трафика. При этом с RX всё нормально.
sh version
SoftWare Version 7.0.3.5(R0241.0085)
BootRom Version 7.2.25
HardWare Version 1.0.2
vlan 5
name SNR_MIRROR
Interface Ethernet1/0/1
description "## UPSTREAM ##"
switchport access vlan 43
Interface Ethernet1/0/17
description ## RASPBERRY PI3 ##
switchport mode trunk
switchport trunk allowed vlan 5;555
switchport trunk native vlan 43
monitor session 1 source interface Ethernet1/0/1 tx
monitor session 1 destination interface Ethernet1/0/17
monitor session 1 remote vlan 5
Tx трафик на интерфейсе E1/0/1 есть

Но в дампе на устройстве - только переиодически проскакивающие ARP запросы

При этом если добавляю
(config)#monitor session 1 source interface Ethernet1/0/1 rx
то в дампе трафик появляется

Нужна какая то дополнительная настройка?
Заранее спасибо за помощь.
