1.3.6.1.4.1.161.19.3.4.2.1.1.18
This counter is incremented every time a transmit packet is dropped due to lack of resources (e.g., transmit FIFO underflow), or an internal MAC sublayer transmit error not counted by in either the TxLateCollision or the TxExcessiveCollision counters.
Identification
{1 3 6 1 4 1 161 19 3 4 2 1 1 18}
A counter is cumulative. To estimate a rate, subtract two readings and divide by the elapsed time; use the units stated in the MIB.
Counter values can wrap or reset. A decrease alone does not distinguish a wrap from a reset, and multiple wraps between readings cannot be recovered reliably. Check the device's discontinuity indicators when available.
Published counter width: 32 bits. SMIv2: Counter32 · Counter64
At least one MIB declaration places this object in a table row. A value belongs to a row instance; its suffix depends on the row's INDEX or AUGMENTS definition.
In CMM3-MIB, the row index portNumber is declared as INTEGER. A non-negative index value is encoded as one numeric subidentifier. An instance has the form .1.3.6.1.4.1.161.19.3.4.2.1.1.18.<portNumber>. Use an index value actually present on the device and permitted by its MIB. Other definitions can differ.
Published row index variants: mirSrcPortNumber; portNumber.
