# SDLC Address Table

The table displays the following information:

Address (sdlcLSAddress)

LS State (sdlcLSOperState)

Comms Mode (sdlcLSOperDATMODE)

Modulus (sdlcLSOperMODULO)

Max PDU Send Size (sdlcLSAdminMAXDATASend)

Max UnAck I-Frames In (sdlcLSAdminMAXIN)

Max UnAck I-Frames Out (sdlcLSAdminMAXOUT)

Num Re-Xmit In Retry Seq (sdlcLSAdminRETRIESm)

Num Retry Sequence (sdlcLSAdminRETRIESn)

Retry Sequence Pause (sdlcLSAdminRETRIESt)

Last Failed Time (sdlcLSOperLastFailTime)

Last Failed Cause (sdlcLSOperLastFailCause)

### Address (sdlcLSAddress)

Poll address of the secondary link station for the SDLC link. Indicates the SDLC link station within a single SDLC port.

### LS State (sdlcLSOperState)

Operational state of the SDLC link station.

Possible values are:

discontacted(1),

contactPending(2),

contacted(3),

discontactPending(4)

### Comms Mode (sdlcLSOperDATMODE)

Communication mode with the adjacent link station.

Possible values are:

half (1) | Two-way-alternate communciaton mode.
full (2) | Two-way-simultaneous communication mode.

### Modulus (sdlcLSOperMODULO)

Modulus for an SDLC link station.

The modulus determines the size of the rotating acknowledgement window used by the SDLC link station pair.

### Max PDU Send Size (sdlcLSAdminMAXDATASend)

Maximum PDU size that a local link station can send to the adjacent link station before receiving any XID from the active line state(ALS).

After the maximum PDU size the ALS can receive is known (via XID exchange), the value is reflected in sdlcLSOperMAXDATASend and takes precedence over Max PDU Send Size.

Note: The value includes the transmission header (TH) and the request header (RH)

### Max UnAck I-Frames In (sdlcLSAdminMAXIN)

Maximum number of unacknowledged I-frames an SDLC link station can receive. The range is from 1 to the value of (sdlcLSAdminModulo-1). The value is send in XID to ALS.

A write operation to the administered value will not change the operational value, sdlcLSOperMAXIN, until the link station is cycled inactive.

### Max UnAck I-Frames Out (sdlcLSAdminMAXOUT)

Maximum number of consecutive unacknowledged I-frames an SDLC link station can send without an acknowledgement. The range is from 1 to the value of (sdlcLSAdminModulo-1).

For link stations on switched SDLC lines, certain implementations can override the administered value with the value received in the XID exchange.

An implementation can support only modulo 8, only modulo 128, or both.

### Num Re-Xmit In Retry Seq (sdlcLSAdminRETRIESm)

Number of retries in a retry sequence for the local SDLC link station.

A retry sequence is a series of retransmitted frames (data or control) for which no positive acknowledgement is received.

Default is 15.

### Num Retry Sequence (sdlcLSAdminRETRIESn)

Number of times a retry sequence is repeated for the local SDLC link station.

Default is zero.

### Retry Sequence Pause (sdlcLSAdminRETRIESt)

Interval between retry sequences for the local SDLC link station if multiple retry sequences are specified.

A retry sequence is a series of retransmitted frames (data or control) for which no positive acknowledgement is received.

### Last Failed Time (sdlcLSOperLastFailTime)

sysUpTime when the SDLC link station last failed.

Value is zero if the link station has not failed.

### Last Failed Cause (sdlcLSOperLastFailCause)

Cause of the last SDLC link station failure.

Displays undefined if the link station did not failed.

Possible values are:

- undefined(1),

- rxFRMR(2),

- txFRMR(3),

- noResponse(4),

- protocolErr(5),

- noActivity(6),

- rnrLimit(7),

- retriesExpired(8)

Default is undefined(1)
