Distributed Trunking is a link aggregation technique, where two or more links across two switches are aggregated together to form a trunk. The IEEE standard—802.3ad—limits the links that can be aggregated within a single switch/device. This feature uses a new proprietary protocol DTIP to overcome this limitation and support link aggregation for the links spanning across the switches. DT provides node-level L2 resiliency in an L2 network, when one of the switches fails. The downstream device (e.g., a server or a switch) perceives the aggregated links as coming from a single upstream device. This makes interoperability possible with third party devices that support IEEE 802.3ad.
User can configure the Distributed Trunking using one of the following:
- Manual Trunks (without LACP)
- LACP trunks
