1.5.b Layer 2, Layer 3
Surprisingly, the Switch blueprint does not mention routed ports or SVI’s (switched virtual interfaces) specifically. However, in this section we get the first hint of Layer 3 on a switch so now is a good time to expound a bit. Naturally, the Certification Guides and Foundation Learning Guides are indispensible throughout the certification process, and while the blueprint is a great road map, it may not mention everything. So you need a bit of everything and for that there is a whole internet out there to be had. So go forth and be all up inside the internet.
As a matter of first importance, you need to find out about what number of sorts of switches are there wireless routers for office under $50 On the off chance that you have a little system of PCs, a straightforward remote switch with fundamental setup is sufficient
Multilayer switching is what it says it is; switches can support more layers than layer 2. Simply put, the switch is a router.
Multiple access ports can be assembled into one Vlan and share a common Gateway address to other layer 3 capable devices. This describes a Switched Virtual interface.
The three hallmarks of SVI creation are:
make a vlan
make an interface vlan, assign it an ip address and turn it up with no shut
and make sure to assign at least 1 port to the vlan.
By default an SVI is created for you, Vlan 1, you just need to give it an address, and you know by default all ports belong to Vlan 1 out of the box.
