Modify User Label of TL

Perform the following steps to modify/edit the user label of a Topological Link (TL):

1. Go to Topology menu and click Topology View option. Topology View window is launched.
2. Click Network View (Nodes) tab and select the desired partition.
3. Do one of the following:
   • Right-click the desired TL between two nodes and select the option Modify Userlabel. Modify TL window is displayed.
   • Select the desired TL, go to Topology menu tab and select (Modify User Label) option. Modify TL window is displayed.

     

4. Enter the desired text in the New Userlabel text box provided. Characters supported are a-z, A-Z, 0-9, &, . (dot), - (hyphen), _ (underscore), space.
5. Click OK. Operation Successful message is displayed.
6. Click OK.

   Select Show TrunkLabel check box on Network View (Nodes) tab and double-click the TL to view its user label.
