What is usrVHASecurSharedSecretKey?

It holds the shared secret key for this mobility security association, used to authenticate registration messages between the PDSN and the paired Radio Node. An admin writes this to configure the key, but reading it always returns a zero-length value over SNMP, a deliberate design choice so the secret can never be recovered by polling the device.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.429.4.84.5.1.1.4
snmpwalk -v2c -c public <target> USR-VHA-MIB::usrVHASecurSharedSecretKey

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.429.4.84.5.1.1.4.1
snmpget -v2c -c public <target> USR-VHA-MIB::usrVHASecurSharedSecretKey.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.429.4.84.5.1.1.4.1 s <value>
