What is the range of usable VLANs on a Cisco switch?

The range of usable VLANs on a Cisco switch is from 1 to 4094. VLANs (Virtual Local Area Networks) are identified by a number known as the VLAN ID, which can range from 1 to 4095. However, VLAN IDs 0 and 4095 are reserved and not usable for regular VLAN configurations. Thus, the usable VLAN range for network segmentation and traffic management purposes is from 1 to 4094.

This answer captures the essential functionality of VLANs in a Cisco environment, which allows network administrators to logically separate networks and enhance security and performance. The higher range allows for significant scalability in larger networks, enabling effective traffic management and organization.
