ingress tagged traffic on unmanaged switch
Hi guys, I'm sure this has been asked but I'm not able to find a relevent discussion. Simpyl I'd like to know how does the netgear's unmanged switchports handle ingress tagged traffic ? Do t...
Hi eyesofra,
I inquired your concern to a higher tier of NETGEAR Support. With regard to your questions, it depends on the ASIC (Application-Specific Integrated Circuit) of the switch, and the switch itself. New switches (with E such as GS108Ev3) will likely pass through (based on MAC table). On older, non-E switches, it would fail CRC and drop the packet. E-switches without VLANs may still be aware of VLANs and be able to pass them through.
However, it is advisable that you should not implement an 802.1Q unaware switch in network wherein you have expectation of persevering 802.1Q traffic. There is reason for Plus switches, this would be one of them.Regards,

Hi DaneA,
I understand where you're coming from and appreciate your feedback. However at this stage, I'm trying to understand the behaviour of an unmanaged prosafe switch for the given scenario. Knowing it's a store and forward is good starting point :)
So know how would it handle tagged traffic ingressing it's port ? Does it drop it due to unrecognized ethertype if it even looks at ethertype ?
Or since it's storing the frame, does it drop anything above 1518 ?
Cheers
