What is ifDescr?
This read-only object provides a textual description of a network interface, typically including the manufacturer name, product name, and hardware/software version. An operator would read this value to quickly identify the type and version of interface hardware installed on the device. This is useful for inventory management and troubleshooting hardware compatibility issues.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.2.1.2.2.1.2 snmpwalk -v2c -c public <target> IF-MIB::ifDescr
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.2.1.2.2.1.2.1 snmpget -v2c -c public <target> IF-MIB::ifDescr.1
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> ifDescr.1
