What is cmmATCommand?

This read-write field holds a free-form, user-defined AT command string, up to 256 characters, that the device automatically terminates with a carriage return and a NULL character before sending to the target modem. Admins use this to issue arbitrary diagnostic or configuration commands directly to a specific modem's command interpreter, beyond what the structured MIB objects otherwise expose. For example, an admin might write a custom vendor-specific AT command into cmmATCommand to query an obscure modem parameter not otherwise represented in this MIB.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.52.4.1.1.18.1.5.1
snmpwalk -v2c -c public <target> CT-CMMPHYS-MIB::cmmATCommand

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.52.4.1.1.18.1.5.1.1
snmpget -v2c -c public <target> CT-CMMPHYS-MIB::cmmATCommand.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.52.4.1.1.18.1.5.1.1 s <value>
