tcpServerConnectionDownDTR

Module: MOXA-W2x50A-MIB

OID (symbolic): MOXA-W2x50A-MIB::tcpServerConnectionDownDTR

OID (numeric): 1.3.6.1.4.1.8691.2.13.1.4.1.2.3.1.1.9

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: For some applications, serial devices must obtain the Ethernet link status from the DTR signal sent by the NPort W2x50A 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 tcpServerConnectionDownDTR?

Controls the DTR signal's behavior when the TCP Server mode's Ethernet link goes down: 'goes low' (1) drops DTR so an attached serial device can detect the link loss, or 'always high' (0) leaves it unaffected.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.8691.2.13.1.4.1.2.3.1.1.9
snmpwalk -v2c -c public <target> MOXA-W2x50A-MIB::tcpServerConnectionDownDTR

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.8691.2.13.1.4.1.2.3.1.1.9.1
snmpget -v2c -c public <target> MOXA-W2x50A-MIB::tcpServerConnectionDownDTR.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.8691.2.13.1.4.1.2.3.1.1.9.1 i <value>

SNMPv3 example:

snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> tcpServerConnectionDownDTR.1
