VLAN Trunking - Remembering which combination creates a Trunk Link
Thursday, 6 December 2007
Ah, you've probably seen the table and thought to yourself "that doesn't look bad." Well let's make it easier:
1. If one end of the link is configured as an access port then the link will NOT trunk.
2. If BOTH ends of the link are AUTO then the link will NOT trunk
3. If one end is a trunk and the other is auto BUT THE TRUNK PORT IS CONFIGURED FOR NO-NEGOTIATION then the link will NOT trunk.
4. ALL OTHER COMBINATIONS WILL TRUNK
