This state indicates that ports A and B connect to two different

concentrators that connect to the same ring.

•5=wrap AB

• 6 = through

This is the normal, non-wrap operating state for a dual-attached station.

• 7 = local A

• 8 = local B

• 9 = local AB

•10=local S

•11=cwrap A

This state indicates that FDDI wrapped port A of the FDDI link or net

module because port B is not receiving data.

Make sure that the port B cable is not disconnected and that the port is

functional. One of the two fibers leading into port B may be broken.

Troubleshoot the cable.

•12=cwrap B

This state indicates that FDDI wrapped port B of the FDDI link or net

module because port A is not receiving data.

Make sure that the port A cable is not disconnected and that the port is

functional. Troubleshoot the cable.

Use the Technician Interface to look at the values of the following

attributes in the wfFddiMacEntry object. The

get

command is next to the

attribute name. Or, use this Quick Get path to access them: wfLine

wfFddiGroup

wfMacGroup

wfFddiMacTable

• wfFddiMacUpstreamNbr (

get wfFddiMacEntry.4.*)

This shows the MAC address of the upstream neighbor in the ring. Use it

to determine whether the router wrapped the ring.

• wfFddiMacDownstreamNbr (

get wfFddiMacEntry.5.*)

This shows the MAC address of the downstream neighbor in the ring. Use

it to determine whether the router wrapped the ring.
