Rapid Spanning Tree Protocol | 907
Verify that EdgePort is enabled on a port using the show spanning-tree rstp command from the EXEC
privilege mode or the
show config command from INTERFACE mode; Dell Force10 recommends using
the
show config command, as shown in Figure 44-7.
Figure 44-7. EdgePort Enabled on Interface
FTOS Behavior: Regarding bpduguard shutdown-on-violation behavior:
1 If the interface to be shutdown is a port channel then all the member ports are disabled in the hardware.
2 When a physical port is added to a port channel already in error disable state, the new member port will
also be disabled in the hardware.
3 When a physical port is removed from a port channel in error disable state, the error disabled state is
cleared on this physical port (the physical port will be enabled in the hardware).
4 The
reset linecard command does not clear the error disabled state of the port or the hardware disabled
state. The interface continues to be disables in the hardware.
The error disabled state can be cleared with any of the following methods:
•Perform an
shutdown command on the interface.
•Disable the shutdown-on-violation command on the interface ( no spanning-tree stp-id portfast
[
bpduguard | [shutdown-on-violation]] ).
•Disable spanning tree on the interface (no spanning-tree in INTERFACE mode).
•Disabling global spanning tree (no spanning-tree in CONFIGURATION mode).
