Note that switches can maintain an IP stack, which enables us to manage the switches either locally, as well as remotely by Telnet.įrame tagging is a technique used to uniquely identify a frame as it is forwarded through the switch fabric.ġ. The subnet portion of the switch IP address must match the subnet number of the management VLAN. To associate a switch with a management VLAN, you need to assign an IP address to the switch. A VLAN operating on a Catalyst switch limits transmission of unicast, multicast, and broadcast traffic to only the other ports belonging to that VLAN, thereby controlling broadcasts. Using VLAN technology, you can group switch ports and their connected users into logically defined communities of interest.
Like routers, switches (Layer 2) have the ability to provide domain broadcast segmentation called a VLAN.
All devices working on a VLAN will have same broadcast domain. Layer2 Technologies 1.3 Configure and Verify VLANsĪ VLAN is a group of devices on one or more logically segmented LANs.
