Cisco – Switch Port with Multiple Devices

ciscoswitch

I understand that each port of a legacy switch can be connected to a device via ethernet cable. Thus, it is possible that one port can have multiple devices? This is because in SDN, this thing is possible since you can program it but I don't know if it is applicable in traditional networks.

I'm not sure that I understand your question.

You could have a hub or another switch connected to a switch port, and the traffic from many devices could come through a single switch port, especially if the switch is a root bridge.

I made Trunk at HP using LACP Active and I made bonding at CloudeCore using balance-rr which gave me load balancing at all 3 Ethernet cables between floors and also backup if cables get failure :D

Assigning an IP Address Based on Switch Port

is it possible to assign a preconfigured IP address based on a port a device is connected to? What devices do I need for this?

You can use a Cisco switch and an IOS that supports DHCP Server Port-Based Address Allocation on your switch; you also must issue DHCP from your switch. Assume that you have got Fa0/1 and Fa0/2 in Vlan120.

ip dhcp use subscriber-id client-id
ip dhcp subscriber-id interface-name
ip dhcp excluded-address 192.0.2.1 192.0.2.10
!
ip dhcp pool VLAN120
   network 192.0.2.0 255.255.255.0
   default-router 192.0.2.1
   dns-server 192.0.2.5
   reserved-only
   address 192.0.2.101 client-id "Fa0/1" ascii
   address 192.0.2.102 client-id "Fa0/2" ascii

This configuration reserves addresses for fa0/1 and fa0/2. The same address will always be assigned to those ports.
