Using ATX Trunking

helddown — trunking is enabled, but the trunk connection has been rejected. Indicates that an error has been detected and the link is being held out of service until the error condition clears. After a short time-out period, another attempt will be automatically initiated to establish a good trunk connection.

broken — the port has been configured for trunking, but is physically non- operational.

Rmt Bridge Id

Displays the MAC address portion of the remote bridge’s bridge ID.

NOTE

The Rmt Bridge Id field can be used to determine which ports belong to which trunk group. Ports in the same trunk group will have the same remote bridge ID.

Rmt IP Address

Displays the remote bridge’s IP address.

Last Error

Displays the reason for failure when the link is in a helddown state. Reasons for failure include:

(1) none — no error; the trunking protocol may restart with no error conditions when trunking is activated for a port or when the MIB variable that controls extra trunk groups is modified.

(2) in-bpdu— a spanning tree BPDU was received, indicating that the connection is not point-to-point, or that the far end of the link does not have trunking enabled.

(3) multiple-bridges— a different bridge has been connected at the far end of the link, and the trunking protocol will restart.

(4) ack-lost(acknowledgment lost) — the far end of the link has detected a problem, and the trunking protocol will restart.

(5) standby — the trunk group is filled to capacity with other ports; this port is now a hot standby. If another port leaves the trunk group, this port will then be included in the group.

(6) too-many-groups— the maximum number of groups (4) has been reached, and a new group cannot be added. This port will not be used until the condition clears.

(7) no-ack(no acknowledgment) — this port has not received a valid trunking packet, and the trunking protocol will restart.

(8) perturbed-threshold— errors are preventing stabilization, and the trunking protocol will restart.
