Description
Bridge priority is used in selecting the root device, root port,
and designated port. The device with the highest priority becomes the
STP root device. However, if all devices have the same priority, the
device with the lowest MAC address will then become the root device.
(Note that lower numeric values indicate higher priority.)
Default: 32768
Range: 0-61440, in steps of 4096
Options: 0, 4096, 8192, 12288, 16384, 20480, 24576, 28672,
32768, 36864, 40960, 45056, 49152, 53248, 57344, 61440.
path cost method is used to determine the range
of values that can be assigned to each interface.
Long: Specifies 32-bit based values that range from 1-200,000,000.
(This is the default.)
Short: Specifies 16-bit based values that range from 1-65535.
Protection Switch will operate on MAC deleting continuly if meets TC attacking,
this will affect packet forwarding. User can configure the operating
sequency of BPDU packet to avoid TC-BPDU attacking.
Protection The threshold time needed by TC.3 times in 2s at default. The
configuratable time range is 1-255.
