mesmPortAutoDuplexMode

Module: XYLAN-PORT-MIB

OID (symbolic): XYLAN-PORT-MIB::mesmPortAutoDuplexMode

OID (numeric): 1.3.6.1.4.1.800.2.3.3.2.1.5

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-only

Description: The automatically detected port duplex mode of this MESM port.

What is mesmPortAutoDuplexMode?

Reports the duplex mode this MESM port has automatically detected: full-duplex(1), half-duplex(2), auto-duplex(3), or unknown(4). A port stuck at half-duplex when full-duplex was expected is a classic cause of high error counts and poor throughput, so admins check this value first when diagnosing such symptoms.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.800.2.3.3.2.1.5
snmpwalk -v2c -c public <target> XYLAN-PORT-MIB::mesmPortAutoDuplexMode

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.800.2.3.3.2.1.5.1
snmpget -v2c -c public <target> XYLAN-PORT-MIB::mesmPortAutoDuplexMode.1
