1.3.6.1.4.1.248.11.150.1.0.14
The total number of topology changes detected by this bridge since the management entity was last reset or initialized.
Identification
{1 3 6 1 4 1 248 11 150 1 0 14}
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 scalar group. A scalar instance uses the suffix .0.
