Best Practices
Naming Conventions
- Use descriptive names (Servers, Guest, Voice)
- Include location if managing multiple sites
- Avoid spaces (use underscores or hyphens)
- Document VLAN purposes in network diagram
Security Tips
- Separate management VLAN from user traffic
- Use private VLANs for guest networks
- Implement VLAN ACLs for inter-VLAN routing
- Disable unused VLANs on switches
VLAN ID Ranges
| Range | Description | Usage |
|---|---|---|
| 0 | Reserved | Not used for normal traffic |
| 1 | Default VLAN | Default for all ports (should be changed) |
| 2-1001 | Normal Range | Standard VLANs, stored in vlan.dat |
| 1002-1005 | Reserved (Legacy) | Token Ring and FDDI (rarely used) |
| 1006-4094 | Extended Range | For large networks, not all switches support |
| 4095 | Reserved | Reserved by 802.1Q standard |
