Study Notes
VLAN Configurations
- A trunk link is a point-to-point link between two network devices that carries multiple VLANs.
Network Environment
- The primary role of a trunk link in a network environment is to connect multiple VLANs between two devices, such as switches or a switch and a router.
OSI Model
- Switches are primarily associated with Layer 2 of the OSI model, and they only use MAC address information from network traffic.
Ethernet Frame Headers
- VLAN membership information is included in Ethernet frame headers, specifically in the 802.1q header.
Trunk Link Frames
- For each frame transferred over a trunk link, two pieces of information must be identified: the VLAN membership and the MAC address of the destination device.
VLAN Membership Identification
- The process used to identify VLAN membership for frames transferred over a trunk link is tagging.
VLAN Trunk Definition
- A trunk is defined as a single physical link that carries multiple VLANs between two devices.
