SL-ENTITY-MIB: View SNMP OID List / Download MIB

This table contains one row per physical entity. There is always at least one row for an overall physical entity.

Information about a particular physical entity.

The Slot number of the entity.

A textual description of physical entity. This object should contain a string which identifies the manufacturers name for the physical entity, and should be set to a distinct value for each version or model of the physical entity. Example: PacketLight-Oc, PacketLight-Ethernet, ... The actual value should be taken from the E2prom.

An indication of the general hardware type of the physical entity. An agent should set this object to the standard enumeration value which most accurately indicates the general class of the physical entity, or the primary class if there is more than one. If no appropriate standard registration identifier exists for this physical entity, then the value other(1) is returned. If the value is unknown by this agent, then the value unknown(2) is returned.

The vendor-specific hardware revision string for the physical entity. The preferred value is the hardware revision identifier actually printed on the component itself (if present). Note that if revision information is stored internally in a non-printable (e.g., binary) format, then the agent must convert such information to a printable format, in an implementation-specific manner. If no specific hardware revision string is associated with the physical component, or this information is unknown to the agent, then this object will contain a zero-length string.

The vendor-specific firmware revision string for the physical entity (normally the boot-revision). Note that if revision information is stored internally in a non-printable (e.g., binary) format, then the agent must convert such information to a printable format, in an implementation-specific manner. If no specific firmware programs are associated with the physical component, or this information is unknown to the agent, then this object will contain a zero-length string.

The vendor-specific software revision string for the physical entity. Note that if revision information is stored internally in a non-printable (e.g., binary) format, then the agent must convert such information to a printable format, in an implementation-specific manner. If no specific software programs are associated with the physical component, or this information is unknown to the agent, then this object will contain a zero-length string.

The vendor-specific serial number string for the physical entity. The preferred value is the serial number string actually printed on the component itself (if present). On the first instantiation of an physical entity, the value of slEntPhysicalSerialNum associated with that entity is set to the correct vendor-assigned serial number, if this information is available to the agent. If a serial number is unknown or non-existent, the slEntPhysicalSerialNum will be set to a zero-length string instead. Note that implementations which can correctly identify the serial numbers of all installed physical entities do not need to provide write access to the slEntPhysicalSerialNum object. Agents which cannot provide non-volatile storage for the slEntPhysicalSerialNum strings are not required to implement write access for this object. Not every physical component will have a serial number, or even need one. Physical entities for which the associated value of the slEntPhysicalIsFRU object is equal to false(2) (e.g., the repeater ports within a repeater module), do not need their own unique serial number. An agent does not have to provide write access for such entities, and may return a zero-length string. If write access is implemented for an instance of slEntPhysicalSerialNum, and a value is written into the instance, the agent must retain the supplied value in the slEntPhysicalSerialNum instance associated with the same physical entity for as long as that entity remains instantiated. This includes instantiations across all re- initializations/reboots of the network management system, including those which result in a change of the physical entitys slEntPhysicalIndex value.

The value of slEntPhysicalIndex for the physical entity which protects this physical entity. A value of zero indicates this physical entity has no protecting physical entity. This object is not applicable should the protection be done on a per-port basis.

The protection state of physical entity. This object is not applicable should the protection be done on a per-port basis. In the case of Switch protection the following logic should be used: 1. If there is only one card is present - noProtection(3) 2. If the standby card is not ready - the active card should have the value noProtection(3), and the standby card should have the value protecting(2) 3. If the protecting card is ready - the active card should have the value working(1) and the standby card should have the value protecting(2)

The protection mode of physical entity. The default value is automatic(3) This object is not applicable should the protection be done on a per-port basis.

The physical entity status bitmap: 1 - Card is removed from the slot 2 - Communication Fault 4 - Major alarm inherited from the ports 8 - Card or port HW failure 16 - An internal SW failure detected 32 - SW version mismatch detected 64 - Power A Failure 128 - Power B Failure 256 - HW version mismatch detected 512 - Minor alarm inherited from the ports

Text that describes the last entity failure.

The desired state of the interface. The testing(3) state indicates that no operational packets can be passed. When a managed system initializes, all interfaces start with ifAdminStatus in the down(2) state. As a result of either explicit management action or per configuration information retained by the managed system, ifAdminStatus is then changed to either the up(1) or testing(3) states (or remains in the down(2) state). State warmBoot(4) cause the card a Warm Start. The state coldBoot(5)has two meanings. If the card is present it means to reinitialize it with the factory defaults. This is equivalent to Cold Start. Setting the object to the value hotBoot(7) cause the card to reboot in a non service affecting manner. If the card is not present it means that the former configuration of this slot is not longer kept in the system. In this case the slot is ready for insertion of a new card of any type.

The current operational state of the interface. If slEntPhysicalAdminStatus is down(2) then slEntPhysicalOperStatus should be down(2). If slEntPhysicalAdminStatus is changed to up(1) then slEntPhysicalOperStatus should change to up(1) if the interface is ready to transmit and receive network traffic It should remain in the down(2) state if and only if there is a fault that prevents it from going to the up(1) state; it should remain in the notPresent(6) state if the interface has missing (typically, hardware) components.

The number of timer ticks since the last reboot of the module.

The type of the physical module.

The Clei Code resides in the SEEP of each card.

The card part number. This is a string of upto 12 characters.

The oem-specific serial number string for the physical entity. The preferred value is the serial number string actually printed on the component itself (if present). On the first instantiation of an physical entity, the value of slEntPhysicalSerialNum associated with that entity is set to the correct vendor-assigned serial number, if this information is available to the agent. If a serial number is unknown or non-existent, the slEntPhysicalSerialNum will be set to a zero-length string instead. Note that implementations which can correctly identify the serial numbers of all installed physical entities do not need to provide write access to the slEntPhysicalSerialNum object. Agents which cannot provide non-volatile storage for the slEntPhysicalSerialNum strings are not required to implement write access for this object. Not every physical component will have a serial number, or even need one. Physical entities for which the associated value of the slEntPhysicalIsFRU object is equal to false(2) (e.g., the repeater ports within a repeater module), do not need their own unique serial number. An agent does not have to provide write access for such entities, and may return a zero-length string. If write access is implemented for an instance of slEntPhysicalSerialNum, and a value is written into the instance, the agent must retain the supplied value in the slEntPhysicalSerialNum instance associated with the same physical entity for as long as that entity remains instantiated. This includes instantiations across all re- initializations/reboots of the network management system, including those which result in a change of the physical entitys slEntPhysicalIndex value.
