Group Set Member link located below the table; the IP Group Set Member table appears.
Table 25-5: IP Group Set Table Parameter Descriptions
Defines an index number for the new table row.
Note: Each row must be configured with a unique index.
Defines a descriptive name, which is used when associating the row in other
tables.
Note:
■ Each row must be configured with a unique name.
■ The parameter value cannot contain a forward slash (/).
Defines the load-balancing policy.
■ [0] Round-Robin = (Default) The device selects the next consecutive,
available IP Group for each call. The device selects the first IP Group in
the table (i.e., lowest index) for the first call and the next consecutive IP
Groups for the next calls. For example, first call to IP Group at Index 0,
second call to IP Group at Index 2, third call to IP Group at Index 3, and so
on. If an IP Group is offline, the device selects the next consecutive IP
Group. Once the last IP Group in the IP Group Set list is selected for a
call, the device goes to the beginning of the list and sends the next call to
the first IP Group, and so on.
■ [1] Random Weight = The device selects IP Groups at random and their
weights determine their probability of getting chosen over others. The
higher the weight, the more chance of the IP Group being chosen.
■ [2] Homing = The device always attempts to send all calls to the first IP
Group in the table (i.e., lowest index). If unavailable, it sends the calls to
the next consecutive, available IP Group. However, if the first IP Group
comes online again, the device selects it.
Note: For the Random Weight optional value, use the 'Weight' parameter in
the IP Group Set Member table (below) to configure weight value per IP
Group.
Assigns a Dial Plan tag that is used to determine whether the incoming SIP
dialog is sent to IP Groups belonging to this IP Group Set. The parameter is
used when IP-to-IP Routing rules are configured for destination based on tags
(i.e., 'Destination Type' parameter configured to Destination Tag). For more
information on routing based on destination tags, see
Routing Destinations.
The valid value is a string of up to 70 characters. By default, no value is
defined. You can configure the parameter with up to five tags, where each tag
is separated by a semicolon (;). Each tag can have a name and value (e.g.,
Country=Ireland) or only a value (e.g., Ireland). You can also configure
multiple tags with the same name (e.g., Country=Ireland;Country=Scotland).
Note: If the IP Groups belonging to the IP Group Set are also configured with
Dial Plan tags, the Dial Plan tag configured for the parameter takes
precedence. If the same Dial Plan tag is also configured for other IP Groups in
the IP Groups table, the IP Group Set takes precedence and the device sends
the SIP dialog to the IP Group(s) belonging to the IP Group Set.
