tcpEStatsStackSoftErrors

Module: TCP-ESTATS-MIB

OID (symbolic): TCP-ESTATS-MIB::tcpEStatsStackSoftErrors

OID (numeric): 1.3.6.1.2.1.156.1.1.5.1.21

Node type: OBJECT-TYPE

Type: ZeroBasedCounter32

Access: read-only

Description: The number of segments that fail various consistency tests during TCP input processing. Soft errors might cause the segment to be discarded but some do not. Some of these soft errors cause the generation of a TCP acknowledgment, while others are silently discarded.

What is tcpEStatsStackSoftErrors?

Count of segments that failed a consistency check during TCP input processing (see tcpEStatsStackSoftErrorReason for which check); some soft errors are silently dropped while others still trigger an ACK, so a rising count is worth investigating even if the connection otherwise looks healthy.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.2.1.156.1.1.5.1.21
snmpwalk -v2c -c public <target> TCP-ESTATS-MIB::tcpEStatsStackSoftErrors

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.2.1.156.1.1.5.1.21.1
snmpget -v2c -c public <target> TCP-ESTATS-MIB::tcpEStatsStackSoftErrors.1
