7.70 Priority (Bridge Parameters)

Description
VB Priority (Bridge Parameters) indicates the fixed parameters of the bridge, used for
selecting the role of the bridge and computing the topology of the spanning tree. As the value
of the parameter decreases, the VB priority increases and the bridge is more likely to be selected
as a root bridge.
Impact on the System
Changing the value of Priority may affect the selection of a root bridge, which may finally affect
the entire network topology.
Values
Value Range
0-65535, in step length of 4096
Configuration Guidelines
Set this parameter according to what role the user expects the bridge to play in the spanning tree
topology.

The STP is a Layer 2 management protocol that avoids Layer 2 loops by selectively
blocking redundant network links and supports the link backup.
The RSTP develops from the STP and shortens the convergence time.
