Parameters
interface interface-type interface-number: Specifies an interface by its type and number.
ect ect-number: Specifies an ECT algorithm index in the range of 1 to 16.
standby slot slot-number: Specifies a subordinate device by its IRF member ID. If you do not specify a subordinate device, the command displays information for the master device.
Examples
# Display AP information for ECT algorithm 1 on FortyGigE 1/0/1.

Table 4: Command output
Field | Description |
---|---|
TxDigest | Local agreement digest. |
RxDigest | Agreement digest of the neighbor. |
NBRAPMode | AP mode of the neighbor:
|
TxAN | Local agreement number. |
TxDAN | Local discarded agreement number. |
RxAN | Neighbor's agreement number. |
RxDAN | Neighbor's discarded agreement number. |
TxValid | Validity of the local digest. |
RxValid | Validity of the neighbor's digest. |
MisOrder | Whether the message is out of order. |
TopoAgree | Whether the topologies of the two sides match. |
CalcEnd | Whether topology calculation has been finished. |
AgreeSend | Digest transmit mode:
|
SystemID | System ID of the root on the SPT that contains the port. |
Role | Current port role:
|
SelectedRole | Newly computed role for the port:
|
PSTState | PST state of the port, including discarding, learning, and forwarding. |
ReRoot | Whether a reroot is required for the port. |
Agree | Whether the port sends the Agreement flag. |
Agreed | Whether an Agreement has been received. An agreement indicates that the port states and transmitted priority vectors for the other bridge attached to this LAN are compatible with a loop-free active topology determined by this port's priority vectors. |
Sync | Whether a port state synchronization is required on the port. |
Synced | Port state synchronization state. |
Forward | Whether the port is to be placed in forwarding state. |
Forwarding | Whether the port is in forwarding state. |
