-The problem is with the DLCI_port model type. In SPECTRUM, the
port would toggle between GREEN and RED (up and down) after a
DLCI connection was made then broken on a router supporting DLCI.
There is an attribute called "dlcistate" which is one of 11 internal/
external attributes for the DLCI_port model type. In one particular
case, when the connection between two DLCI ports broken, nine out of
the 11 external reads fail on the near end router -- dlciState is one of
them. These failed attributes get put into an unsupported external
attributes list for that model, and write 0 values to the corresponding
internal attributes. Then these failed external attributes are NEVER
read again. That's why after the disconnection, the internal attribute
dlciState was not consistent with the external attributes. However
due to another code error, if the read of dlciState was within 10
seconds from a previous read, the old value of 2 was returned. That's
why the dlciState toggling between 0 and 2 (up and down).
The resolution is to use the first three external reads after a
disconnection to build the unsupported external attributes list. An
attribute will be added to the list only if it has failed on for all three
reads. This will prevent attributes from being added to this list
prematurely and NEVER read again.
