In telecommunications, trunking is a method for a system to provide network access to many clients by
sharing a set of lines or frequencies instead of providing them individually. This is analogous to the structure of a
tree with one trunk and many branches. Trunking, is set by the configuration software, the two or more physical
ports get together into a logical path to increase the bandwidth between the switch and the network node.
Trunking is a packaging technology, it is a peer to peer link, both ends of the link are switches, it can be a switch
and a router, and also can be a host, switch or router. Based on port trunking function that allows between two or
more ports between switches, switches and routers, hosts the switch or router connected in parallel to provide for
the simultaneous transmission of higher bandwidth and greater throughput, significantly entire network
capacity. Trunking is more economical to increase the bandwidth between the switch and network device, such as
servers, routers, workstations, or other switches. Trunking function is to integrate more than one physical port
(typically 2-4) to a logical channel.

Device supported 4 trunking group, operate method: choice apply, choice the port need to trunking
the port list, Choice setting, available after reboot. If the port already set to Ring port, it can not set to
trunking port. Each trunking group at least have 2 port member, at more 4. 1 port can not exit in 2 trunking
group
1.The trunking groups require all the attributes can be the same, including speed, duplex, STP state etc.
2.If you do not confirm the STP state, please disable RSTP function, or close others, leaving only one STP channel.
3.Port 1 as the system reserved, can not be used as trunking.
4.The ports of having been set to the port aggregation that can not be set to ring ports.
6.6.2 Rapid Ring
SwRing
TM
technology provides auto-recovery and reconnection mechanism for broken network. When
network is broken, it has link redundancy and self-recovery capability and self-recovery time is less than 20ms.
SW-Ring is the patented technology of Shenzhen 3onedata Technology Co.,Ltd. designed for industrial control
network requiring high reliability.
SwRing
TM
technology support maximum 250 pieces switches, in which the
SwRing
TM
its self-recovery
time is <20ms.
Each port of IES7110 series switch can be Ring Port to connect other switches. When network is broken,
relay for failure alarm will be activated. Redundant organization of
SwRing
TM
enable backup link to recover
network instantly.
