Description
Lists the values for the following bridge timers: hold time,
topology change, hello time, max age, and forward delay.
List the number of seconds since the last:
• hello time
• topology change
• notification
• aging
Displays the Interface type slot/port information and the
status of the interface (Disabled or Enabled).
Displays the path cost, priority, and identifier for the
interface.
Displays the priority and MAC address of the root bridge of
the STG that the interface belongs.
Displays the designated port ID.
from TenGigabitEthernet 1/3
