This chapter describes X.25 Transport over TCP/IP (XTP) messages. For information on message content and how to use the message, refer to the Introduction.
| XTP.002 |
Level: U-INFO
Short Syntax: XTP.002 q overflow, nt network ID
Long Syntax: XTP.002 Queue overflow on packet from net network ID
Description: This message is generated when there is a input queue overflow causing the forwarder to discard the packet.
Cause: Input queue overflows happen when a packet is received from an interface that is short on buffers and the length of the XTP queue is greater than the fair share. This may be caused by either a burst or steady state of traffic arriving faster than the XTP forwarder can forward it.
Action: Reduce traffic bursts. Upgrade to a faster router.
