Differentiate between IEEE 802.1Q and Cisco's Inter-Switch Link (ISL) tagging methods in VLAN trunking.
IEEE 802.1Q and Cisco's Inter-Switch Link (ISL) are two distinct methods used in Virtual Local Area Network (VLAN) trunking to carry multiple VLANs over a single link between switches. Understanding the differences between these tagging methods is crucial for network administrators to effectively manage VLANs within their network infrastructure. IEEE 802.1Q, also known as dot1q,
What is the purpose of VLAN tagging on trunk links, and how does it help maintain VLAN segregation?
VLAN tagging on trunk links plays a crucial role in maintaining VLAN segregation within a network infrastructure. Virtual Local Area Networks (VLANs) are used to segregate broadcast domains in a network, providing enhanced security, improved performance, and simplified network management. When multiple VLANs need to be carried over a single physical link (trunk link), VLAN
