Deleting a Linkset
After Discovery, the linksets in your network are known to SGM and added to the
SGM database. Physically deleting linksets from your network is not the same as
deleting them from the SGM database. The following sections describe the
differences between deleting linksets from your network and from the SGM
database, and the procedures for doing so:
•Deleting a Linkset from Your Network, page3-88
•Deleting a Linkset from the SGM Database, page3-88

Deleting a Linkset from Your Network

If you physically delete a known linkset from your network, it remains in the SGM
database, SGM labels it Unknown, and it is the system administrator’s
responsibility to delete it from the SGM database, if you choose to do so. SGM
labels all associated nodes Warni ng and all associated links Unknown.
When you redefine the linkset (that is, when you define a linkset with the same
destination point code as the original linkset, but not necessarily with the same
linkset name), SGM rediscovers the linkset and labels it with the appropriate
status (such as Active).

Deleting a Linkset from the SGM Database

Typically, you delete a linkset in the SGM database for one of the following
reasons:
•You have physically deleted the linkset from your network. This is the most
common reason for deleting a linkset from the SGM database.
•The linkset is Unknown or Unavailable, you are aware of the reason, and you
no longer want to see it in SGM displays. For example, the linkset might be
associated with a node that was removed from the network, or it might be a
previously discovered linkset associated with a test lab device.
If you have physically deleted a known linkset from your network, and you then
delete it from SGM, it is no longer in the SGM database, it does not appear in
SGM windows, and it is not discovered when you run Discovery.
