Why Does The Switch Respond With Startup-Config Is Not Present?

Switches in the networking

In networking, switches are the device that is at the 2 layers of the open system interconnection. The main purpose of the switches is to connect the devices and with the help of the packet switching it can transfer receive and move the data packets over the network. The switch allows the transmission only with a single device at a time, not with multiple devices.it allows the information exchange between connected devices.

The switch has various ports through which the devices are plugged in, as soon as the data frames reach the port in the network the destination address is examined a few other requirements checked, and then they are sent to their destination device. Switches support unicast, multicast, and broadcast communication.

Characteristics of the switches 

Some of the switch’s characteristics are in the following:

• The switch is at the data link layer of the OSI model.
• The switch can originate as the multiple network bridge.
• The MAC address is used by the switch to send the data packets to their destination.
• The packet switching is used to send the data to the destination port.
• It gives the association to unicast, multicast, and broadcast transmission.
• It focuses on the full-duplex mode which means the transmission happens between the channels at both ends so that the collision may not happen.
• The errors in the packets are also rechecked by switches.
• The ports in the switches are 24/38.

Variety of the switches

There are different types of switches which are discussed below:

Unmanaged switch

These are the cheap switches that are present in the home network or for the small businesses. by plugging into the port they can start working their operations. If someone wants to connect the various device you just need more plugs for the connection.

Manages switches:

These are the expensive switches that are for the higher organization and the complicated network and they can also be customized to develop the features of the standard switch. The features are QoS, good control, and the management of the network. The fact of their cost has bot effect on its use most of the higher organization are using it because they are flexible and have greater scalability. The SNMP (simple network management protocol) is for the configuration of the message.

LAN switch:

The LAN switch establishes the connection between the devices on an internal LAN of the organization. Other names of the LAN switch are Ethernet or data switch. The network compression and the bottlenecks are solved with the help of the LAN switch. to avoid overlapping the bandwidth are provided with the requirements.

PoE switch:

The PoE stands for the power over Ethernet for the Gigabit Ethernet.it combines the data and the power transmission of the same cable for the reason that the connected devices receive the data and the electricity at a time.

Why does the switch respond with startup-config is not present?

Answer: The switch response along with startup-config is not available or present because the start-up config is not saved at that point.
