wfCSMACDAlignmentMode
Module: Wellfleet-CSMACD-MIB
OID (symbolic): Wellfleet-CSMACD-MIB::wfCSMACDAlignmentMode
OID (numeric): 1.3.6.1.4.1.18.3.4.1.1.36
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: Enables special frame re-alignment in the Line Driver. Only needed when 4 ethernet interfaces are configured on a single slot. Only needed if experiencing transmit underflow errors (wfCSMACDUfloTx). When this attribute is set to DISABLED, non-optimally aligned frames are transmitted as is. When this attribute is set to ALL (1), all non-optimally aligned frames are re-aligned before transmission. When this attribute is set to ALIGN_OVER_128_BYTES (2), all non-optimally aligned frames over 128 bytes in length are re-aligned before transmission and frames up to and including 128 bytes in length are transmitted as is.
What is wfCSMACDAlignmentMode?
Controls special frame re-alignment used mainly on Quad Ethernet (QENET) modules to fix transmit underflow errors: disabled leaves frames as-is, all(1) re-aligns every non-optimally aligned frame, and the third setting only re-aligns frames over 128 bytes. An admin enables this specifically when seeing wfCSMACDUfloTx increment on a QENET-based interface.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.18.3.4.1.1.36 snmpwalk -v2c -c public <target> Wellfleet-CSMACD-MIB::wfCSMACDAlignmentMode
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.18.3.4.1.1.36.1 snmpget -v2c -c public <target> Wellfleet-CSMACD-MIB::wfCSMACDAlignmentMode.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.18.3.4.1.1.36.1 i <value>
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> wfCSMACDAlignmentMode.1
