Module: JUNIPER-MIMSTP-MIB
OID (symbolic): JUNIPER-MIMSTP-MIB::jnxMIMstBufferOverFlowCount
OID (numeric): 1.3.6.1.4.1.2636.3.46.1.1.3.1.30
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description: The number of times Buffer overflows/failures have occured. A Trap is generated on the occurence of this event.
What is jnxMIMstBufferOverFlowCount?
This counter tracks the number of times memory buffer allocation has failed or overflowed during Multiple Spanning Tree (MSTP) processing on a Juniper device. When buffer exhaustion occurs, the device generates an alert trap and increments this counter, signaling potential resource stress. Network operators monitor this to detect memory pressure and potential packet loss during periods of high spanning tree activity.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.2636.3.46.1.1.3.1.30 snmpwalk -v2c -c public <target> JUNIPER-MIMSTP-MIB::jnxMIMstBufferOverFlowCount
Get a specific instance (index 1):
