Linkset Table

The linkset table displays information about the linksets that have been
discovered by SGM.

Linksets that are associated with nodes that are excluded from the current view
are not displayed in the linkset table. See the “Creating a New View” section on

page 4-68 for more information about excluding nodes.

To see mouse over help popup for each column in the table, place the cursor over
a column header.

If a cell is too small to show all of its data, place the cursor over the cell to see the
full data in a mouse over help popup.

You can resize each column, or sort the table based on the information in one of
the columns. By default, this table is sorted by Status, and SGM displays all of
the columns in the Linkset Table except Internal ID, Node, SP, Congested
Links, and Last Status Change.

Viewing Basic Information for Linksets

• To display hidden columns, right-click in the table header and select the

checkboxes for the columns you want to display.

• To hide columns, right-click in the table header and clear the checkboxes for

the columns you want to hide.

See the “Resizing, Sorting, and Hiding Table Columns” section on page 3-53 for
more information about resizing, sorting, displaying, or hiding columns.

The linkset table contains the following columns:

Column Description

Internal ID Internal ID of the linkset. The internal ID is a unique ID for every object,

assigned by SGM for its own internal use. It can also be useful when the TAC is
debugging problems.

Name Name of the linkset.

Node Node associated with the linkset.

Signaling Point Signaling point associated with the linkset.

Local Point Code Point code of the primary signaling point for the linkset.

Column Description

Linkset Type Type of linkset, which SGM determines by examining the links defined in the

linkset. Possible linkset types are:

• HSL—The links in this linkset use the SS7-over-ATM (Asynchronous

Transfer Mode) high-speed protocol.

• SCTPIP—The links in this linkset use the Stream Control Transmission

Protocol (SCTP) IP transport protocol.

• Serial—The links in this linkset use the serial SS7 signaling protocol.

• Mixed—The links in this linkset are of two or more types. (This

configuration is not recommended.)

• Virtual—The links in this linkset are virtual links, which connect signaling

point instances running on the same device. SGM does not poll virtual
linksets, nor does it display real-time data or accounting statistics for virtual
linksets.

Note Prior to IOS release 12.2(23)SW1, virtual linksets on multi-instance

routers were created manually by the user. Within and after that release,
virtual linksets are created automatically.

• Other—No links have been defined for this linkset.

Links Total number of links in the linkset.

Active Links Number of links in the linkset that are Active.

Congested Links Number of links in the linkset that are Congested.

Ignored Indicates whether the linkset is to be included when aggregating and displaying

SGM status information:

• Clear the checkbox to include the linkset. This is the default setting.

• Select the checkbox to exclude the linkset.

This field can be edited by users with authentication level Power User (Level 2)
and higher.

Notes Indicates whether there is a note associated with the linkset.
