SDLC Circuits

To monitor link station information for an SDLC port:

  1. Select a serial port from 4 A/S Serial card. A yellow border appears around the port.

  2. Double-click or right-click and choose Configure from the pop up menu.

  3. Select SDLC circuits... from the Category pull down menu.

  4. Select a row and click the OK button.

The information for that station is displayed as follows:

Local Busies (sdlcLSStatsLocalBusies)

Monitors the total number of times that the local SDLC link station has entered a busy state since link station startup.

At link station start up time, this object must be initialized to zero.


Remote Busies (sdlcLSStatsRemoteBusies)

Monitors the total number of times that an adjacent (remote) SDLC link station has entered a busy state since link station startup.

At link station start up time, this object must be initialized to zero.


Retransmits Out (sdlcLSStatsRetransmitsOut)

Monitors the total number of information frames retransmitted to a remote link station. Frames are retransmitted when N(r) sent by the remote link station indicate that one or more frames were lost.


IFrames In (sdlcLSStatsIFramesIn)

Monitors the total number of information frames received from an adjacent SDLC link station since link station startup.

At link station start up time, this object must be initialized to zero.


IFrames Out (sdlcLSStatsIFramesOut)

Indicates the total number of information frames transmitted to an adjacent SDLC link station since link station startup.

At link station start up time, this object must be initialized to zero.


Protocol Errors (sdlcLSStatsProtocolErrs)

Indicates the number of times that the SDLC link station has inactivated the link since it was started up. The link is inactivated when a link station receives a frame that violates the SDLC protocol from an adjacent link station.

At link station start up time, this object must be initialized to zero.


Polls In (sdlcLSStatsPollsIn)

Indicates the number of polls received from an adjacent SDLC link station since link station startup.

At link station start up time, this object must be initialized to zero.


Polls Out (sdlcLSStatsPollsOut)

Indicates the number of polls sent to an adjacent SDLC link station since link station startup.

At link station start up time, this object must be initialized to zero.


Response In (sdlcLSStatsPollRspsIn)

Indicates the total number of poll responses received from the adjacent SDLC link station since station startup.

At link station start up time, this object must be initialized to zero.


Response Out (sdlcLSStatsPollRspsOut)

Indicates the number of poll responses sent from this link station to the adjacent SDLC link station since station startup.

At link station start up time, this object must be initialized to zero.


FRMR In (sdlcLSStatsFRMRsIn)

Indicates the total frame reject (FRMR) frames received from an adjacent SDLC link station since link station startup.


FRMR Out (sdlcLSStatsFRMRsOut)

Indicates the total frame reject (FRMR) frames transmitted to an adjacent SDLC link station since link station startup.


REJs In (sdlcLSStatsREJsIn)

Indicates the total REJ frames received from an adjacent SDLC link station since link station startup.
