snmpwalk -v2c -c public <target> 1.3.6.1.4.1.449.2.1.3.1.1.2.1.51
snmpwalk -v2c -c public <target> X25-OPT-MIB::cdx6500X25StatSignalingState

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.449.2.1.3.1.1.2.1.51.1
snmpget -v2c -c public <target> X25-OPT-MIB::cdx6500X25StatSignalingState.1
