EdgePort

EdgePort allows the interface to forward traffic approximately 30 seconds sooner as it skips the Blocking and Learning states.

CAUTION: Configure EdgePort only on links connecting to an end station. EdgePort can cause loops if you enable it on an interface connected to a network. Edge ports do not receive BPDUs.
NOTE: Whenever a port becomes a designated port, it will start a timer called the edge delay while timer (hello-time + 1/2 * hello-time); if the hello-time is set to 2 seconds, the edge delay while timer is 3 seconds. If BPDUs are not received for 3 seconds, then the port is declared as oper edge on the fly and is moved to forwarding state.

OS10 supports auto edge feature . If the port does not receive BPDU for the hello-time + one second interval then it places the port into auto edge mode.

If the edge port receives any BPDU, it looses the edge port property.

  • Enable EdgePort on an interface in INTERFACE mode.
