Detailed explanation-1: -Trunk links are physical links between switches or between switches and routers. The data frames transmitted on a trunk link must be tagged so that devices can identify the VLAN to which the data frames belong. Therefore, a trunk link can carry data frames of multiple VLANs, as shown in Figure 1-1.

Detailed explanation-2: -A trunk port is a type of connection on a switch that is used to connect a guest virtual machine that is VLAN aware. Generally, all frames that flow through this port are VLAN tagged. The exception to this is when a trunk port is granted access to the untagged VLAN set (native VLAN ID).

Detailed explanation-3: -A network trunk is a communications line or link designed to carry multiple signals simultaneously to provide network access between two points. Trunks typically connect switching centers in a communications system. The signals can convey any type of communications data.

Detailed explanation-4: -There’s no limitation on the number of trunk ports you can configure. However, there is a switch-wide limitation of 64 instances of Spanning Tree. In other words, you can only have 64 active VLANs on the switch.
