What is chasControlDTEWordSize?

This object holds the current (and desired) word size for serial port 1 (DTE, the modem port), defaulting to 8 bits at power-on. This must match the attached modem's configuration for reliable dial-in management access, making it one more parameter to check when out-of-band modem access to the chassis stops working. A modem configured for 7-bit data against a chassis still at the default chasControlDTEWordSize of 8 would fail to establish a clean dial-in management session.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.800.2.1.3.1.1.8
snmpwalk -v2c -c public <target> CHASSIS-MIB::chasControlDTEWordSize

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.800.2.1.3.1.1.8.1
snmpget -v2c -c public <target> CHASSIS-MIB::chasControlDTEWordSize.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.800.2.1.3.1.1.8.1 i <value>
