• Log in to the device using SSH or Telnet.

• Enter the show version command.

• Look for the line that starts with 'uptime'.

• The uptime will be displayed in the format of days, hours, minutes, and seconds.

• Alternatively, you can use network monitoring tools like Nagios, PRTG, or SolarWinds to monitor uptime.

VLAN stands for Virtual Local Area Network. It is a logical grouping of devices on a network, allowing for better network management and security.

• VLANs divide a single physical network into multiple virtual networks.

• They help in reducing network congestion and improving network performance.

• VLANs can be configured on switches using commands like 'vlan database', 'vlan ', and 'interface switchport access vlan '.

LAN/WAN refers to local area network and wide area network respectively. VLAN is a virtual LAN that allows for logical segmentation of a network.

• LAN is a network that covers a small geographical area, typically within a single building or campus.

Routing and switching are fundamental concepts in computer networking that involve directing and forwarding data packets.

• Routing is the process of determining the best path for data packets to travel from one network to another.

• Switching is the process of forwarding data packets within a network based on their destination MAC addresses.

• Routing protocols like OSPF and BGP are used to exchange routing information between routers.

• Switches use MAC address tables to determine the ...read more

Access ports are used to connect end devices, while trunk ports are used to carry traffic between switches.

• Access ports are assigned to a single VLAN and carry traffic for that VLAN only.

• Trunk ports can carry traffic for multiple VLANs using VLAN tagging.

• Access ports are typically used for devices like computers, printers, and IP phones.

• Trunk ports are used to interconnect switches or connect to network devices like routers or servers.

• An example of an access port configuratio...read more
