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.
