Port Group Management and Control Functions 245
Port Group
Management and
Control Functions
Management and control functions to define port groups are provided in
the system.
Defining Port Groups
You can configure port groups from the
bridge packetFilter
portGroup
menu of the Administration Console, as described in the
Command Reference Guide .
This section briefly discusses the control and management functions that
are implemented in the system for port groups.
You need to assign the port groups before you can assign packet filters to
the port groups.
Important Considerations
■
Creating a new group — When you create a new port group, an
unused port group must be available. A port group is limited to the
number of ports on a system.
■
Listing groups — You can list the port groups currently defined on
the system. The group id, group name (if any), group mask, and the
slots where the group is loaded are displayed.
■
Displaying groups
— The display of a port group shows the group
id, the name of the group, and all the addresses or ports included in
that group.
■
Deleting groups
— When you delete port groups from a module,
those groups are no longer available for use in packet filters.
■
Adding Ports to Groups
— When you add ports to an existing
group, you can either enter the ports at the prompts or import them
from a file. At least one port group must exist before you can add
ports. The same port may be in multiple port groups.
■
Port group size — The maximum number of ports that a port group
can contain is 24, which is the maximum number of ports on a
system.
