What is LLDP? The link layer discovery protocol ( LLDP ) is an open and extendable part of the Internet protocol suite used in IEEE 802 to advertise a device’s identity and abilities, as well as other devices connected within the same network. LLDP Link Layer Discovery Protocol LLDP is mainly used in wired Ethernet-connected devices to facilitate management of network resources and simplify networking tasks for administrators in a multi-vendor network. The protocol’s multi-vendor support enables network discovery of devices and management tools like Simple Network Management Protocol (SNMP) in a network made up of devices from different manufacturers. LLDP makes it unnecessary to use a larger number of proprietary protocols to support a multi-vendor network or, on the other hand, limit oneself to the hardware of a single vendor. LLDP is also known as Station and Media Access Control Connectivity Discovery, as specified in IEEE 802.1AB. Simil...

Network Address and Mask Network address – It identifies a network on internet.  Using this, we can find range of addresses in the network and total possible number of hosts in the network. Mask – It is a 32-bit binary number that gives the network address in the address block when AND operation is bitwise applied on the mask and any IP address of the block. The default mask in different classes are : Class A – 255.0.0.0 Class B – 255.255.0.0 Class C – 255.255.255.0 Example : Given IP address 132.6.17.85 and default class B mask, find the beginning address (network address). Solution : The default mask is 255.255.0.0, which means that the only the first 2 bytes are preserved and the other 2 bytes are set to 0. Therefore, the network address is 132.6.0.0.   Subnetting: Dividing a large block of addresses into several contiguous sub-blocks and assigning these sub-blocks to different smaller networks is called subnetting. It is a practice that is ...
