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.

Table 4: Command output

Field

Description

TxDigest

Local agreement digest.

RxDigest

Agreement digest of the neighbor.

NBRAPMode

AP mode of the neighbor:

  • Both—Performs AP check for both unicast and multicast FDB entries.

  • Multicast—Performs AP check only for multicast FDB entries.

  • Off—AP mode is disabled.

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:

  • Normal—The agreement digest was sent at the normal speed.

  • Fast—The agreement digest was fast flooded.

SystemID

System ID of the root on the SPT that contains the port.

Role

Current port role:

  • ROOT—Root port.

  • ALTE—Alternate port.

  • DESI—Designated port.

SelectedRole

Newly computed role for the port:

  • ROOT—Root port.

  • ALTE—Alternate port.

  • DESI—Designated 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.
