E2899 Cmd Rej: NEI LBP has already been defined for the CCS7 link
For each SS7 signaling link, the rle=nei parameter can be specified for only one loopback point. That loopback point must be the terminating SS7 signaling link component.
Recovery
Display all the loopback points on the signaling links for this STP. Enter the rtrv-lbp command.
Verify that the link has an NEI LBP configured. The loopback point IDs for each signaling link are displayed in numerical order in the LBP field. The NEI LBPs are listed last and are identified by NEI in the RLE field of the output.
Re-enter the ent/chg-lbp command that generated this error message, specifying a valid combination of parameters. Refer to the command description in Commands User's Guide and to the Database Administration - SS7 User's Guide for assistance.
