Resetting Bgp Connections - Huawei Quidway NetEngine80E Configuration Manual

HUAWEI NetEngine80E/40E Router
Configuration Guide - IP Routing
Context
If an error occurs on a BGP peer connection, BGP generates an error code and subcode. If the
error occurs on the local device, the local device changes its local state machine to disconnect
its BGP peer and sends a BGP Notification message to its BGP peer. After the BGP peer receives
the Notification message, the BGP peer records the error code and subcode carried in the message
and changes its state machine.
By default, BGP records peer status changes and event information in the system log files. The
record includes: BGP error codes and subcodes, BGP state machine changes, and whether BGP
Notification messages are sent. The system log files serve as a reference to locate network
connectivity faults.
If you do not want BGP to record peer status changes or event information, run the undo peer
log-change command. After you run the undo peer log-change command, BGP records only
the last peer status change in the log file. You can run the display bgp peer loginfo command
to view this log.
