Enabling an Edge Port
The edge port feature (Portfast) enables interfaces to begin forwarding packets immediately after they are
connected. When enabled as an edge port, an interface skips the blocking and learning states so that it can
start forwarding traffic sooner (typically saving 30 seconds that the switch would use to check for loops).
To enable an edge port, use the following command.
MSTP Configuration Example
The following example creates two MST instances to accommodate two bridged VLANs.

Note: Only interfaces connected to end stations should be set up as edge ports.
Edge ports in 802.1D mode are not supported.
