port4Config
Module: CMM3-MIB
OID (symbolic): CMM3-MIB::port4Config
OID (numeric): 1.3.6.1.4.1.161.19.3.4.3.21
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: Link speed configuration on port 4.
What is port4Config?
This read-write enumeration sets the link speed and duplex mode for port 4 on the CMM-III, choosing among auto-negotiate, 100 or 10 Mbit/s, and full or half duplex. An admin cares about it because a mismatched forced speed/duplex on port 4 is a classic cause of excessive collisions or dropped throughput on that link. For instance, forcing port4Config to tenFDX(4) locks port 4 to 10 Mbit/s full duplex to match an older device that cannot auto-negotiate reliably.
Examples
Walk all instances (SNMPv2c):

Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.161.19.3.4.3.21.1 snmpget -v2c -c public <target> CMM3-MIB::port4Config.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.161.19.3.4.3.21.1 i <value>
