EX4100 has two NICs, LAN1 and LAN2. They can be used independently (with link aggregation off), or combined in various manners.
In either case, one can assign a VLAN to each (combined or non-combined) interface. Is it possible to assign a second VLAN to the same interface (with a different ip address etc)
My case scenario is the following: my box serves two different lan segments. Thus I have disabled link aggregation and lost my failover capability (in case one of the NICs goes kaput, or one of the switch ports the EX4100 is connected to has a similar problem).
If I could assign two VLANs to an interface, I could combine the two ports using LACP (my managed switch is also LACP compliant) and then assign two VLANs to the combined interface, each having its own ip addresses/subnet etc.
