ifExtnsTestCode

Module: RFC1229-MIB

OID (symbolic): RFC1229-MIB::ifExtnsTestCode

OID (numeric): 1.3.6.1.2.1.12.2.1.6

Node type: OBJECT-TYPE

Type: OBJECT IDENTIFIER

Access: read-only

Description: This object contains a code which contains more specific information on the test result, for example an error-code after a failed test. Error codes and other values this object may take are specific to the type of interface and/or test. However, one subject identifier:

testCodeUnknown OBJECT IDENTIFIER ::= { 0 0 }

for use if no additional result code is available. Note that testCodeUnknown is a syntactically valid object identifier, and any conformant implementation of ASN.1 and the BER must be able to generate and recognize this value.

What is ifExtnsTestCode?

This object carries a code with more specific detail about the outcome of the most recent interface test, such as an error code following a failed test. Because the meaning of specific codes is defined per interface and test type, admins use it alongside ifExtnsTestResult to pinpoint the exact failure reason rather than just knowing a test failed. If no additional detail is available, the agent returns the reserved value testCodeUnknown ({0 0}).

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.2.1.12.2.1.6
snmpwalk -v2c -c public <target> RFC1229-MIB::ifExtnsTestCode

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.2.1.12.2.1.6.1
snmpget -v2c -c public <target> RFC1229-MIB::ifExtnsTestCode.1

SNMPv3 example:

snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> ifExtnsTestCode.1
