- `ip routing` — Enable Layer 3 routing
- `interface
Switch Management and Monitoring Commands
Maintain and monitor switch health:
- `show version` — Show hardware and software info
- `show interfaces` — Display interface status
- `show spanning-tree` — View Spanning Tree Protocol status
- `show mac address-table` — List MAC addresses learned
- `reload` — Restart switch
- `copy running-config startup-config` — Save configuration
