Understanding Port Trunk Groups
Port trunk groups are used to combine a number of ports together to make a single high-bandwidth data pipeline. The
Switch supports up to 32 port trunk groups with two to eight ports in each group. A potential bit rate of 8000 Mbps can
be achieved.
Description
Select the unit you want to configure.
Select the port you want to configure.
The MSTI ID of the instance to be configured. Enter a value between 0 and 15. An entry
of 0 in this field denotes the CIST (default MSTI).
This parameter is set to represent the relative cost of forwarding packets to specified ports
when an interface is selected within an STP instance. Selecting this parameter with a
value in the range of 1 to 200000000 will set the quickest route when a loop occurs. A
lower Internal cost represents a quicker transmission. Selecting 0 (zero) for this parameter
will set the quickest route automatically and optimally for an interface.
Enter a value between 0 and 240 to set the priority for the port interface. A higher priority
will designate the interface to forward packets first. A lower number denotes a higher pri-
ority.
