Configuring each Port CST Configuration Page
Selection Criteria
Interface
- Selects one of the physical or LAG interfaces associated with VLANs associated with the
CST.
Admin Edge Port
- Specifies if the specified port is an Edge Port within the CIST. It takes a value of
Enable or Disable, where the default value is Disable.
BPDU Guard
- Specifies whether BPDU Guard is enabled for the Common and Internal Spanning
tree (CST). Value is enabled or disabled
BPDU Filter
- Specifies whether BPDU Filter is enabled for the Common and Internal Spanning tree
(CST). Value is enabled or disabled
Port Mode
- Spanning Tree Protocol Administrative Mode associated with the port or port channel.
The possible values are Enable or Disable.
Auto Edge
-
Configuring the auto edge mode of a port allows the port to become an edge port if it
does not see BPDUs for some duration. The possible values are Enable or Disable.
Root Guard
-
Configuring the root guard mode sets a port to discard any superior information
received by the port and thus protect against root of the device from changing. The port gets put into
discarding state and does not forward any packets. The possible values are Enable or Disable.
Loop Guard
-
Configuring the loop guard mode prevents a port from erroneously transitioning from
blocking state to forwarding when the port stops receiving BPDUs. The port is marked as being in
loop-inconsistent state. In this state, the port does not forward packets. The possible values are
Enable or Disable.
TCN Guard
-
Configuring the TCN guard for a port restricts the port from propagating any topology
change information received through that port. The possible values are Enable or Disable.
