Configuring 802.1Q Trunks on Cisco Catalyst Switches
Master 802.1Q trunk configuration between Catalyst switches, including VLAN pruning, native VLAN setup, and comprehensive troubleshooting techniques.
Step-by-step Cisco IOS lab to configure 802.1Q trunk links between switches, set native VLAN, allow specific VLANs, and verify with show interfaces trunk . CCNA lab guide.
802.1Q Configuration
Learn how to configure 802.1Q trunking on Cisco switches. Create VLANs, assign ports, enable trunk mode, and verify tagging step by step for the CCNA exam.
More information on NAT configuration can be obtained by our Cisco Router NAT Configuration articles. Summary This article explained the use of router-on-a-stick configurations and showed how you can configure an 802.1q trunk link between a Cisco switch and router.
Configure 802.1Q Trunk on Cisco Switch
Configure an 802.1Q trunk between Cisco switches: tag VLANs, set the native VLAN, prune the allowed list, and verify with show interfaces trunk .
When configuring IEEE 802.1Q tunneling on an edge device, you must use IEEE 802.1Q trunk ports for sending packets into the service-provider network. However, packets going through the core of the service-provider network can be carried through IEEE 802.1Q trunks , ISL trunks , or nontrunking links.
802.1Q Encapsulation Explained
To send traffic for multiple VLANs between switches, you need a trunk link and a trunking protocol. 802.1Q is the most common trunking protocol. A trunking protocol is required because a standard Ethernet frame has no field to identify to which VLAN the Ethernet frame belongs to. 802.1Q solves this by inserting a "tag" into the frame that ...
This tutorial explains the IEEE 802.1Q or dot1q trunking protocol. Learn how IEEE 802.1Q encapsulates Ethernet frames.
Configure 802.1Q Trunking Between Catalyst Switches
This document describes the difference of IEEE 802.1Q (dot1q) trunking between Cisco Catalyst switches that run Cisco IOS® Software.
This lesson explains how 802.1Q tunneling works and how to configure it on Cisco IOS Catalyst Switches.
