The endpoints of TCP connections are instantiated in software through a construct known as a socket. An instance of a TCP socket is defined by the source IP address, source port number, destination address and destination port number.
If any of these parameters change (e.g., a packet arrives with a different source address), then then the software will ...

Unless your PC is configured as a bridge, it does not have a MAC address table.
Since the PC does not forward frames from one interface to another, it has no need for a MAC table.

By the way, 192.169.0.122/.123 are no private IP addresses. You should never use public addresses that you're not authorized to. Check out RFC 1918.
There are two basic approaches:
You configure a separate network (p2p, switch, VLAN) for each machine and connect one server NIC to each network (but both within the 192.169.0.120/21 subnet or larger - which ...

You should put client (access) ports in admin-edge mode. That way, they don't start in STP blocked mode but will forward right away. The default config is auto-edge which causes a notable delay between physical link up and actual L2 connectivity. Since DHCP is tried very early after link up it may fail with auto-edge.
For each access port on the 2530(?), ...

Spanning-tree starts all ports as "blocking" until it can confirm no loop. The process can take up to 30s. On my 2810, without any other explicit configuration, it only takes a few seconds.
