snmpwalk -v2c -c public <target> 1.3.6.1.4.1.33.100.2.2.1.23
snmpwalk -v2c -c public <target> MRV-IR-CHAR-MIB::irCharPortAuthFallback

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.33.100.2.2.1.23.1
snmpget -v2c -c public <target> MRV-IR-CHAR-MIB::irCharPortAuthFallback.1
