What is a leased line core switch

A leased line is a private between two or more locations provided according to a commercial contract. It is sometimes also known as a private circuit, private connect, and as a data line. Traditionally, leased lines were used by businesses to connect geographically distant offices for phone and networking. More recently leased lines are used to establish connectivity between businesses for networking between private, (Colo), and their public.

View VLAN configuration on the core switch

To display VLAN information, use the show vlan command in privileged EXEC mode. show vlan [brief | id vlan-id | name name | ifindex] brief (Optional) Displays only a single line for each VLAN, naming the VLAN, status, and ports. VLANs improve network management and require routing for inter-VLAN communication The. VLAN is a switch feature. It allows you to create a group of devices that share broadcast messages. This guide shows how to configure VLANs on a Cisco switch: creating them, putting access ports into them, adding a voice VLAN for an IP phone, and. This article will focus on configuring VLANs on Cisco switches. We will look at each command necessary to configure the topology below.
