Bridge VLAN Filtering Question

Tue May 09, 2023 6:26 pm

I know there are benefits to using Bridge VLAN filtering for VLANs rather than setting them up via the switch or by using multiple bridges and vice versa. For example using bridge VLAN filtering is a lot tidier than having a bridge per interface and I also know that Hardware Offloading is only possible on a single bridge if you have a single switch chip with VLAN filtering, but what other benefits are there of using this method of VLAN creation over others?

I thought the main advantage was that it was a standard way to do it on ROS devices. It is configured the same independent of the hardware implementation. It isn't guaranteed to be hardware assisted, so there are some platforms that for maximum performance, you can't use the vlan-filtering bridge, because the underlying software support hasn't been developed for the switch chips in the bridge implementation for the platform. But other than performance, the logical functioning works the same.

Its the same reason for using a high level language instead of writing code in Assembly language. Portability.

It works, easy to implement. Want to do it the hard way, fill yer boots.

I'm slow today. Can you explain what you meant by that?

sorry for being metaphorical (unnecessarily)
portability (when we talk cpu-architectures) is a 80% word
(80% work, 20% rusty nails)
