Configuring Interface Settings for STA
– 195 –
configurations because an administrator must manually enable the port.
(Default: Disabled)
BPDU guard can only be configured on an interface if the edge port attribute is
not disabled (that is, if edge port is set to enabled or auto).
◆
BPDU Guard Auto Recovery – Automatically re-enables an interface after the
specified interval. (Range: 30-86400 seconds; Default: Disabled)
◆ BPDU Guard Auto Recovery Interval – The time to wait before re-enabling an
interface. (Range: 30-86400 seconds; Default: 300 seconds)
◆ BPDU Filter – BPDU filtering allows you to avoid transmitting BPDUs on
configured edge ports that are connected to end nodes. By default, STA sends
BPDUs to all ports regardless of whether administrative edge is enabled on a
port. BPDU filtering is configured on a per-port basis. (Default: Disabled)
BPDU filter can only be configured on an interface if the edge port attribute is
not disabled (that is, if edge port is set to enabled or auto).
◆ Migration – If at any time the switch detects STP BPDUs, including
Configuration or Topology Change Notification BPDUs, it will automatically set
the selected interface to forced STP-compatible mode. However, you can also
use the Protocol Migration button to manually re-check the appropriate BPDU
format (RSTP or STP-compatible) to send on the selected interfaces.
(Default: Disabled)
◆
TC Propagate Stop – Stops the propagation of topology change notifications
(TCN). (Default: Disabled)
