Table 177: Spanning-Tree Protocol Configuration Parameters (continued)
Field Function
Max Age Specifies the maximum-aging time in seconds for all MST
instances. The maximum aging time is the number of
seconds a switch waits without receiving spanning-tree
configuration messages before attempting a
reconfiguration.
Max Hops (MSTP only) Specifies the number of hops in a region
before the BPDU is discarded.
Configuration (MSTP only) Specifies the MSTP region name carried in
Name the MSTP BPDUs.
Revision Level (MSTP only) Specifies the revision number of the MSTP
configuration.
Ports
Interface Name Specifies an interface for the spanning-tree protocol.
Cost Specifies the link cost to determine which bridge is the
designated bridge and which interface is the designated
interface.
Priority Specifies the interface priority to determine which
interface is elected as the root port.
Disable Port Disables the spanning-tree protocol on the interface.
Edge Configures the interface as an edge interface. Edge
interfaces immediately transition to a forwarding state.
No Root Port Specifies an interface as a spanning-tree designated port.
If the bridge receives superior STP BPDUs on a
root-protected interface, that interface transitions to a
root-prevented STP state (inconsistency state) and the
interface is blocked. This blocking prevents a bridge that
should not be the root bridge from being elected the root
bridge. When the bridge stops receiving superior STP
BPDUs on the root-protected interface, interface traffic
is no longer blocked.
