socketTcpServerConnectionDownDTR

Module: MOXA-CN2600-MIB

OID (symbolic): MOXA-CN2600-MIB::socketTcpServerConnectionDownDTR

Description: For some applications, serial devices must obtain the Ethernet link status from the DTR signal sent by the Terminal Server CN2600 series device server. If this setting is set to 'goes low,' DTR will change the state to low if the Ethernet link is off.

What is socketTcpServerConnectionDownDTR?

Sets what the DTR signal does when the Ethernet link goes down on a port acting as a TCP server: always-low(1) forces DTR low so the attached serial device can detect the outage, always-high(0) leaves it unchanged.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.8691.2.11.1.4.1.2.2.1.1.9
snmpwalk -v2c -c public <target> MOXA-CN2600-MIB::socketTcpServerConnectionDownDTR

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.8691.2.11.1.4.1.2.2.1.1.9.1
snmpget -v2c -c public <target> MOXA-CN2600-MIB::socketTcpServerConnectionDownDTR.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.8691.2.11.1.4.1.2.2.1.1.9.1 i <value>
