|
Name some Uplink Port |
|
|
Does a switch normally have more uplink ports or access ports? |

|
What is an uplink port? |
Some Ethernet computer networking equipment contains an uplink port. These ports simplify connecting different types of Ethernet devices to each other, such as when linking a local home network to a modem and the Internet. Hubs, switches and routers typically designate one Ethernet port as the uplink connection. |
|
What is an Access Port? |
An "access port" is a type of connection on a switch that is used to connect a guest virtual machine that is VLAN unaware. This port provides the virtual machine with connectivity through a switch that is VLAN aware without requiring it to support VLAN tagging. |
