Hi
Is that IP addressing real?

Hi friend,
Depending on the scenario you have, there are Layer 2 (switch) and 3 (routers) devices. The correct way to understand it is to create vlan in the switches and these vlan are associated with the ports; while the router understands the packets, but the traffic generated by the switch frames the router, what it does is encapsulate through the dot1Q standard in each subinterface to satisfy each request of the connected user, for example:
VLAN 2
Interface Vlan 2
Ip address 192.168.10.2
Interface range fa0/1-5
Switchport mode access
Switchport access vlan 2
You will do the same in the other switches for each vlan you have and do not forget to associate the ports
On the router it creates subinterfaces:
Interface g0/0
No shutdow
Interface g0/0.2
Encapsulation dot1Q 2
Ip address 192.168.10.1
In the links that connect between switches you must apply Etherchannel since it allows the logical grouping of several Ethernet physical links, this grouping is treated as a single link and allows to add the nominal speed of each used Ethernet physical port and thus obtain a high trunk link. speed.
LACP (Link Aggregation Control Protocol) is the "open" option of the protocol. The operation is very similar to that of PAgP with the difference that in this case the roles are assigned to each of the ends in the system priority, which is satisfied with 2 priority bytes plus 6 MAC.
The priority of the port is the lower value indicates higher priority. In this case, up to 16 links can be defined for each EtherChannel.
Below we detail the different operating modes:
In: the strength of the ports to establish the Ether Channel (Disables LACP).
Off: prevents the EtherChannel from being established.
Passive: Place the port waiting to receive LACP packets to negotiate the EtherChannel.
Active: establishes that the port sends packets to start the negotiation with EtherChannel.
