I have a scenarion where, currently, I have eth2/3/4 as part of switch0, three vifs on switch0, each with their own subnet /24. I cable from eth2 to a managed switch and use switch facilities to properly tag untagged on certain ports to desired vlans etc. Works like a charm.
I would like to be able to plug something like a laptop in eth3 or eth4 (currently nothing plugged in) and have it, effectively, participate in one of the vlans. On a switch I would achieve that by tagging untagged traffic with the desired vlan.
It would seem that I could use:
set interfaces switch switch0 switch-port interface eth3 pvid 1
where 1 is the desired vlan id.
It seems my POE does not support this (it complains that the platform does not support it; running 1.9.0), but from what I read, the ER X can do it (and it is what would be best for my situation). Is the ER X doing this in software and is that considered acceptable because of the faster CPU, or is there a fundamental architectural reasons why the POE cannot offer this?
I realize I could simply assign another (new) subnet to switch0, but that is different as it would require additional FW configuration and would end up putting the laptop on a different subnet.
Another option would be to remove the switch from the picture and configure eth2 with all vlans, and eth3 and 4 with vlan tagging, but I am not sure that is supported, and I do not have a spare ER to try this out on.
Any help or explanation would be appreciated.
