Configure the
Locked
setting to prevent the port from learning the MAC addresses of new hosts.
This will help keep intruders off your network since any packet coming from an unknown source

Trunk Groups
Figure 7-9. Trunk Groups window
The Switch supports up to 16 trunk groups. Each module on the Switch supports up to two trunk groups
except Gigabit modules which support multiple trunk groups of ports from different modules. Gigabit trunk
groups must all be of the same media type (for example, -SX, -LX, or –T). Trunks are groups of ports that are
banded together to form a single, logical, high-bandwidth data pipe.
Trunk Groups can be configured by choosing the module that the Trunk Group will reside on, and then
making the appropriate entries in the
Trunk Groups
dialog box for that module. Trunk Groups cannot be
configured with ports on different modules (a Trunk Group must consist of ports that all reside on a single
module).
Items in the above
Trunk Groups
dialog box are defined as follows:
♦
Anchor
The Anchor port for the trunk group. All configuration settings changes made to the anchor port
will automatically be made to the other ports in the trunk.
♦
Name
The user-assigned name of the trunk group.
♦
Members
The continuous number of ports that will be members of the trunk group.
