Broadcom Corporation QLogic 57810 10 Gigabit Ethernet Adapter --Question

Currently, I have two physical hosts. When my VYOS (version 1.2.1) is migrated to a network card type Broadcom COrporation, I find that SSH cannot work. When migrating back to another network card type intel® Ethernet Controller, SSH works normally.

When another VYOS version is 1.1.7, SSH works normally on both physical hosts
I configure QinQ mode for any version of VYOS interface。

Is Broadcom Corporation not supporting VYOS 1.2.1 version QinQ mode?


Hi @Henry, I think it should be supported even at 1.2.x, module bnx2x
Do you have a chance to get the console and look show interfaces?

Hi, Dmitry, thank you for your reply. The configuration is shown below in the Console, and my configuration will not change during the migration. Broadcom Corporation Intel Gigabit

henryj@tpa-vnvy201# show interfaces
ethernet eth0 {

Hi @Henry, I need an output from operation mode show interfaces. If you want to do this from configuration mode, please use run show interfaces

ps:/ You can also mask your private data by adding stripe-private as an example:
run show interfaces | strip-private

Hi @Dmitry,Thank you for your warning

henryj@tpa-vnvy201# run show interfaces | strip-private
Codes: S - State, L - Link, u - Up, D - Down, A - Admin Down

lo u/u


@Henry maybe these ports have different sequences? I mean eth0 this is eth1…
If you use QinQ on eth1 too, check please also ethertype
And also you need to increase MTU on both interfaces

Also. On hypervisor like ESXi you need to set VLAN 4095 and allow promiscuous mode if you don’t do passthrough.
