Do you have massive broadcast domain(s)? Ok.but I highly doubt that's the case in most instances. Why introduce this choke point? Do you need ACL/inspection and don't have that capability at layer 2? Ok. If that's the case, however, you need to ask yourself why you are using VLANs in the first place. It will route between VLANs if you so desire. It consists of a tagged link that allows all VLANs of concern. ![]() What you are describing is commonly known as "router on a stick". The router basically sorts out all the tagged and untagged packets and "routes" them to the proper destination regardless of what VLAN it's on, if any. My understanding is that one has ONE router plugged in to say port 1, and all the other VLANs have port 1 as a MEMBER of their respective VLAN. I think what confuses people is the "isolation" that is a feature of VLANs, vs the packets needing to get to those VLANS. (stacking is a bit different still, as each switch in a stack will maintain its own configuration, whereas a fabric can and should be treated as a single logical chassis) ![]() It's the opposite of a switch fabric.which combines multiple single physical switches into a larger monolithic switch. All that means is that it doesn't remove the VLAN tag when sending frames.Ī VLAN, at it's most basic level, is simply dividing a single physical switch into multiple independent switches. Have a look at viewtopic.php?p=1605303#p1605303įor a port to be in more than one VLAN, it needs to be tagged/trunked. Although I imagine a router is still going to be needed.Ī router may or may not be required, depending on what you want to do. Apparently a port can be a member of more than one VLAN. And with that being said I'm trying to wrap my mind around the implimentation of VLAN's.
