Appendix B: Log Messages

Peer failed PAP authen level 3

The PPP peer’s reported PAP username and/or password does not match the Express XL/XLT’s parameters. This is most likely caused by PPP peer sending incorrect username and/or password. Make sure the Configuration/Connec- tion List/Authentication parameters Rx Username and Rx Password are cor- rectly entered. Also, if using RADIUS, check that the server is configured and running properly.

Peer refused authen level 3

The PPP peer would not allow the Express XL/XLT to authenticate it using the method set in Configuration/Security/PPP.

Peer refused SpanTree level 4

The PPP peer would not participate in the Spanning Tree protocol. This is a warning message only. Bridging will still occur across the WAN port so care must be taken that no loop topologies exist across the connection.

PPPtx[x] … level 6

Advance debugging decode of transmitted PPP configuration packets.

PPPrx[x] … level 6

Advanced debugging decode of received PPP configuration packets.
