IPX: X, unknown SAP packet type received

Generated when the device receives an invalid SAP packet.

IPX: X, demand RIP failed

Generated when this device reaches the end of the attempts to negotiate demand RIP for the IPXCP

connection. After demand RIP has failed, the normal RIP and SAP updates will occur.

LCP X authenticating peer with CHAP

Generated when this device is using CHAP to authenticate the peer (remote) device.

LCP X authenticating peer with PAP

Generated when this device is using PAP to authenticate the peer (remote) device.

LCP X establishing

Generated when the Link Control Protocol of a PPP link or remote site is establishing between this device

and the remote site PPP device.

LCP X no reply to Y Echo-Requests

Generated just prior to a link going down. The link or remote site has gone down due to no replies to the

echo request messages sent.

LCP X operational

Generated when the Link Control Protocol of a PPP link or remote site has been negotiated and is now

operational between this device and the remote site PPP device.

LCP X peer authenticating with CHAP

Generated when the peer (remote) device is using CHAP to authenticate this device.

LCP X peer authenticating with PAP

Generated when the peer (remote) device is using PAP to authenticate this device.

LCP X received Protocol-Reject for <protocol>

Generated when the peer (remote) device rejects one of the Network Control Protocols.

Link X - CSU/DSU Digital Loopback Results [Total: X] [Good: X] [Errors: X]

Generated after the CSU/DSU link module has completed a digital loopback test.

Link X - CSU/DSU Remote Loopback Results [Total: X] [Good: X] [Errors: X]

Generated after the CSU/DSU link module has completed a remote loopback test.

Link X - CSU/DSU Self Test Results [Total: X] [Good: X] [Errors: X]

Generated after the CSU/DSU link module has completed a self test.
