Using Port Trunking
Link aggregation involves grouping links to into a link aggregation group. A MAC client can treat
link aggregation groups as if they were a single link.
The PT-G7509’s port trunking feature allows devices to communicate by aggregating up to 4 trunk
groups, with a maximum of 8 ports for each group. If one of the 8 ports fails, the other seven ports
will automatically provide backup and share the traffic.
Port trunking can be used to combine up to 8 ports between two PT-G7509 switches. If all ports on
both switch units are configured as 100BaseTX and they are operating in full duplex, the potential
bandwidth of the connection will be 1600 Mbps.
In the PT-G7509, the maximum bandwidth for gigabit trunking ports is up to 8 Gbps (Max 9 Giga
ports x 1000 Mbps). Most importantly, please note that “Giga ports can not trunk with 100Mbps
ports”.
