drdasConnectionDownDTR

Module: MOXA-CN2600-MIB

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

OID (numeric): 1.3.6.1.4.1.8691.2.11.1.4.1.2.4.1.1.11

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

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

What is drdasConnectionDownDTR?

Sets what the DTR signal on a DRDAS port does when the Ethernet link goes down: always-low(1) forces DTR low so attached serial equipment can detect the network outage, always-high(0) leaves it unaffected.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.8691.2.11.1.4.1.2.4.1.1.11
snmpwalk -v2c -c public <target> MOXA-CN2600-MIB::drdasConnectionDownDTR

snmpget -v2c -c public <target> 1.3.6.1.4.1.8691.2.11.1.4.1.2.4.1.1.11.1
snmpget -v2c -c public <target> MOXA-CN2600-MIB::drdasConnectionDownDTR.1
