PT-G7509 User’s Manual Featured Functions
3-17
To avoid broadcast storms or loops in your network while configuring a trunk, first disable or
disconnect all ports that you want to add to the trunk or remove from the trunk. After you finish
configuring the trunk, enable or re-connect the ports.
If all ports on both switch units are configured as 100BaseTX and they are operating in full duplex
mode, the potential bandwidth of the connection will be up to 1.6 Gbps. This means that users can
double, triple, or quadruple the bandwidth of the connection by port trunking between two PT
series switches.
Each PT-G7509 can set a maximum of 4 port trunking groups. When you activate port trunking,
certain settings on each port will be reset to factory default values or disabled:
y Communication redundancy will be reset
y 802.1Q VLAN will be reset
y Multicast Filtering will be reset
y Port Lock will be reset and disabled.
y Set Device IP will be reset
y Mirror will be reset
After port trunking has been activated, you may configure these items again for each trunking
ports.

Step 2: Select the Trunk Type (Static or LACP).
Step 3: Select the desired ports under Available Ports and click Up to add to the Trunk Group.
