This is the MIB module for objects used to manage SDLC devices.

This table contains objects that can be changed to manage an SDLC port. Changing one of these parameters may take effect in the operating port immediately or may wait until the interface is restarted depending on the details of the implementation. Most of the objects in this read-write table have corresponding read-only objects in the sdlcPortOperTable that return the current operating value. The operating values may be different from these configured values if a configured parameter was changed after the interface was started.

A list of configured values for an SDLC port.

An octet string that defines the physical port to which this interface is assigned. It has implementation-specific significance. Its value shall be unique within the administered system. It must contain only ASCII printable characters. Should an implementation choose to accept a write operation for this object, it causes the logical port definition associated with the table instance to be moved to a different physical port. A write operation shall not take effect until the port is cycled inactive.

This object describes the role that the link station shall assume the next time a connection is established. Even though this is defined as a port object, it is a link station attribute in the sense that a role is per link station. However, it is not possible to vary link station roles on a particular port. For example, if an SDLC port is configured to primary, all link stations on that port must be primary. Enumeration: 'primary': 1, 'negotiable': 3, 'secondary': 2.

This parameter defines whether the SDLC port is to connect to a leased or switched line. A write operation to this administrative value shall not take effect until the SDLC port has been cycled inactive. Enumeration: 'leased': 1, 'switched': 2.

This parameter defines whether the SDLC port is capable of operating in either a point-to-point or multipoint topology. sdlcPortAdminTopology == multipoint implies the port can also operate in a point-to-point topology. sdlcPortAdminTopology == pointToPoint does not imply the port can operate in a multipoint topology. A write operation to this administrative value shall not take effect until the SDLC port has been cycled inactive. Enumeration: 'multipoint': 2, 'pointToPoint': 1.

This parameter controls the initial value of the administrative status, ifAdminStatus, of this SDLC port at port start-up. Depending on the implementation, a write operation to this administrative object may not take effect until the SDLC port has been cycled inactive. Enumeration: 'active': 2, 'inactive': 1.

This parameter defines the period of time (in 1/100ths of a second) that the port will allow a switched line to remain inactive before disconnecting. A switched line is considered to be inactive if there are no I-Frames being transferred. A value of zero indicates no timeout. Depending on the implementation, a write operation to this administered value may not take effect until the port is cycled inactive. This object only has meaning for SDLC ports where sdlcPortAdminType == switched The object descriptor contains the name of an NCP configuration parameter, ACTIVTO. Please note that the value of this object represents 1/100ths of a second while the NCP ACTIVTO is represented in seconds.

This object defines the minimum elapsed time (in 1/100ths of a second) between any two traversals of the poll list for a primary SDLC port. Depending on the implementation, a write operation to this administered value may not take effect until the port is cycled inactive. The object descriptor contains the name of an NCP configuration parameter, PAUSE. Please note that the value of this object represents 1/100ths of a second while the NCP PAUSE is represented in 1/10ths of a second.

This object defines the number of times the active poll list will be traversed before polling a station on the slow poll list for a primary, multipoint SDLC port.

This object describes the elapsed time (in 1/100ths of a second) between polls for failed secondary link station addresses.

Currently set parameters for a specific SDLC port.

An octet string that describes the physical port to which this interface is currently attached. It has implementation-specific significance.

This object describes the role that the link station has assumed on this connection. Even though this is defined as a port object, it is a link station attribute in the sense that a role is per link station. However, it is not possible to vary link station roles on a particular port. For example, if an SDLC port is configured to primary, all link stations on that port must be primary. The value of sdlcPortOperRole is undefined(3) whenever the link station role has not yet been established by the mode setting command. Enumeration: 'undefined': 3, 'primary': 1, 'secondary': 2.

You might want to look at decreasing the value for sdlcLSAdminMAXDATASend to compensate for the lower quality line.

This trap indicates that the state of an SDLC port has transitioned to active or inactive.

This trap indicates that the state of an SDLC link station has transitioned to contacted or discontacted.
