Network Switch
- Like an old-school switchboard
- Directs network traffic to/from various destinations (ports)****
Managed Switches
- Can be configured via CLI or GUI
- Usually assigned an IP address
- VLANs can only be implemented through manages switches
- Ports can be partitioned into groups
- Switch adds a tag to Ethernet frames to identify the port through which they arrive at the switch
- Identifies the transmissions that belong to each VLAN
- Tag travels with transmission until it reaches a router or switch port connected to destination device
Switch Ports and Trunks
- Port is either configured as an access port or a trunk port
- Access port
- Used for connecting a single node
- Trunk port
- Capable of managing traffic among multiple VLANs
- Trunk
- Single physical connection between switches
- Many logical VLANs can transmit and receive data over
