A management IP address provides remote administrative access to a network device after initial console configuration, allowing administrators to reach the CLI without being physically nearby. section 5.2
On a Layer 2 switch, configure the address on an SVI and specify a default gateway because the switch does not route packets. A router commonly uses a loopback address for stability; a switch commonly uses a dedicated management VLAN to isolate administrative traffic. section 5.2.1
Configure and verify a switch management address
Configure VLAN 1 with 10.0.0.2/24 using `interface vlan 1` and `ip address 10.0.0.2 255.255.255.0`, then set `ip default-gateway 10.0.0.1`. Verify the SVI with `show ip interface brief` and the gateway with `show ip default-gateway`. section 5.2.1
