IPv4 Loopback Interface
- A characteristic of an IPv4 loopback interface on a Cisco IOS router is that it is a logical interface internal to the router.
- It is not assigned to a physical port and cannot be connected to other devices.
Ethernet Frame Size
- The minimum Ethernet frame size that will not be discarded by the receiver as a runt frame is 64 bytes.
Command History Feature
- The command history feature allows you to view a list of commands entered in a previous session.
- It also allows you to recall up to 15 command lines by default.
