Re: vlan on a bridge in a bridge

One thing that nobody mentioned: vlan interfaces are "dumb" tag injectors. They don't implement any logic. Just inject tag or strip tag, depending on the direction and that pose a risk of tagging already tagged frames. And I am not talking about QinQ. I am talking about 3, 4 or even 5 layers of tag...

Re: vlan on a bridge in a bridge

There isn't much odd in your config apart from configuring one bridge (the 100Mbps one) without VLANs while configuring the other one (the 1Gbps one) with VLANs but then use vlan interface to bridge them both together. My guess is that both bridges could be HW offloaded (they use distinct switch ch...

So, if you say that SEXTANT has 6dB more sensitivity than 5HPnD-HG, you would say that SEXTANT @ -71dBm and 5HPnD-HG @ -65dBm have same bandwidth performance?

With 6.1 (default) they show 124V and with 6.18 they show 11.9V and 23°C that is something correct.
