Packet Tracer is commonly used by NetAcad students, since it is available to download after creating a free account. [10] However, due to functional limitations, it is intended by Cisco to be used only as a learning aid, not a replacement for Cisco routers and switches . [ 9 ]
In this case, the longest prefix of the candidate routes is 192.168.20.16/28, since its subnet mask (/28) is longer than the other entry's mask (/16), making the route more specific. Forwarding tables often contain a default route , which has the shortest possible prefix match, to fall back on in case matches with all other entries fail.
[10] The timestamp values returned for each router along the path are the delay values, typically measured in milliseconds for each packet. The sender expects a reply within a configured number of seconds. If a packet is not acknowledged within the expected interval, an asterisk is displayed.
An illustration of hops in a wired network (assuming a 0-origin hop count [1]). The hop count between the computers in this case is 2. In wired computer networking a hop occurs when a packet is passed from one network segment to the next. Data packets pass through routers as they travel between source and destination.
A different slave becomes active if, and only if, the active slave fails. The single logical bonded interface's MAC address is externally visible on only one NIC (port) to simplify forwarding in the network switch. This mode provides fault tolerance. XOR (balance-xor) Transmit network packets based on a hash of the packet's source and destination.

The packet transmission time in seconds can be obtained from the packet size in bit and the bit rate in bit/s as: Packet transmission time = Packet size / Bit rate. Example: Assuming 100 Mbit/s Ethernet, and the maximum packet size of 1526 bytes, results in Maximum packet transmission time = 1526×8 bit / (100 × 10 6 bit/s) ≈ 122 μs
Protocol data units of the OSI model are: [1] The Layer 4: transport layer PDU is the segment or the datagram. The Layer 3: network layer PDU is the packet. The Layer 2: data link layer PDU is the frame. The Layer 1: physical layer PDU is the bit or, more generally, symbol.
