Solved: VLAN TPID 0x88A8 on SG300 series switch

xi00 · ‎10-11-2023

Hello everyone.

I wanted to ask if there is any possibility to get a SG300 series switch to emit a packet encapsulated in a VLAN tag with a TPID of 0x88A8 and not 0x8100?

According to the docs (I was able to reproduce this behaviour) the switch allows semi dot1q-tunneling with the switchport mode customer option. The problem is, however, that this only encapsulates all ingress packets in a normal 802.1q packet with TPID 0x8100. On a (for example) SF220 switch there is the option to set the tpid for trunk ports manually, however the SG300 series does apparently not have this option.

So to finalise, could someone provide me with a minimum working config to get a SG300 switch to transmit a proper 802.1ad packet on a trunk port, or else confidently tell me that this is impossible on 300 series switches so I know that I haven't overlooked something?

Thanks in advance
Christian

- Hardly think this will be possible on small business type devices ,
