Syntax buffers {rising-threshold rising-threshold-val | falling-threshold fallingthreshold-val | severity severity-level} no buffers {rising-threshold | falling-threshold | severity } • rising-threshold-val-The rising message buffer threshold over which a trap will be issued. This is a percentage of messages buffers utilized and ranges from 0 to 100. • falling-threshold-val-The falling threshold value. Once the rising threshold has been crossed, another trap will not be issued until the message buffer has dropped below the falling threshold. This is a percentage of messages buffers utilized and ranges from 0 to 100. • severity-level-The severity level of the trap issued by SNMP. Range is 0 (EMERGENCY) to 7 (DEBUG). Default Configuration The default rising-threshold-val is 80%. The default falling-threshold-val is 50% The default severity level is NOTICE. Command Mode Global Configuration User Guidelines Message buffers are used internally by the switch firmware to pass network PDUs. This includes PDUs such as spanning tree BPDUs or multicast or unicast packets forwarded in software. On rare occasions, a packet storm may cause the switch to become congested due to an excessive number of messages forwarded to the switch CPU. The switch has numerous rate limiters and other mechanisms to appropriately handle such packet floods, however, due to the changing nature of Internet traffic, new types of traffic may cause temporary internal congestion conditions. This command allows the operator to enable the issuance of a trap in such a condition as an aid to early diagnosis and mitigation of the conditions causing traffic to flood the switch CPU. Setting the rising threshold to 0 disables message buffer monitoring. Switch Management Commands 2250
