CALCULATING NETWORK ADDRESS OF AN IP ADDRESS: In this Post I will share you a trick to find out, What is the network address of a IP address. In CCNA or JNCIA Exams we get questions like: what is network address of 172.16.12.100/29? what is network address of 192.168.100.100/26? If it's a class-full subnet (/8, /16, /24) we can find it out easily but in case of a subnetted IP address we required some more time to identify the Sub network IP address. Below is a simple 3 steps formula that gives you accurate Sub-network IP address of any given IP: Step-1: Find out how many hosts we get in that subnet:   (Including Network address and Broadcast address) Like, in  192.168.1.0/24 we get 255 Hosts. 192.168.1.0/29  we get 8 Hosts. 192.168.1.0/30  we get 4 Hosts. Below is the chart that explains how many hosts per bit we get: The above Pic represents the 8 Bits in an octet, And no. of hosts per each bit. So, Clearly if we ...

Configuration of LACP & PAGP: LACP & PAGP: Link Aggregation Control Protocol and Port Aggregation Protocol both sounds same but the gap between these protocols is LACP is Open standard and can be used on any supported Product, where as PAGP is Cisco's proprietary and can be configured only in the Cisco devices. What are these these protocols? Generally we use trunk links to enable communication between two switches (for inter-vlan routing) when we use a single port for the trunk link (e.g., Gig port ) it gives us throughput of 1 Gbps, Making few more ports as trunk causes a loop and STP will block it from farming Configuring the LACP or PAGP gives us the capability to add multiple trunk links to a switch, without causing loops. So that providing more throughput. Port-Channel: When we have bundled multiple interfaces into a trunk group, A new logical interface is created automatically and its called as Port-Channel. When we configure this port channel inter...
