Trunking is using multiple ports/cables to increase bandwidth beyond the capabilities of a single port/cable.  This also increases redundancy for higher availability.  Trunking is usually used in Switch-to-Switch connectivity to increase transmission rates therefore creating bigger data pipelines for mission critical server applications. If VLAN is enabled, network administrator must ensure that the trunking group's ports are within the same VLAN group. TEG-424WS supports use of trunking.
