What is txDeffereds?

Counts transmissions on this interface that had to wait for a quiet, carrier-free network before sending, i.e., deferred transmissions in simplex/half-duplex Ethernet. A rising count signals a busy shared segment where the port is frequently waiting its turn to transmit.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.208.39.4.1.1.20
snmpwalk -v2c -c public <target> ETH-SWITCH-MIB::txDeffereds

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.208.39.4.1.1.20.1
snmpget -v2c -c public <target> ETH-SWITCH-MIB::txDeffereds.1

SNMPv3 example:

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