ifChassisTable

ifChassisFpc

ifChassisEntry 1

The number of the FPC card on which the interface is located in the chassis. It is the chassis slot in which the FPC card is installed for the specified interface.

Although the number is labeled from 0 and up in the chassis, the return value for this object always starts from 1 according to network management convention. Therefore, a value of zero means there is no real or physical FPC associated with the specified interface.

ifChassisPic

ifChassisEntry 2

The number of the PIC card on which the interface is located in the chassis. It is the PIC location on the FPC card for the specified interface.

Although the number is labeled from 0 and up in the chassis, the return value for this object always starts from 1 according to network management convention. Therefore, a value of zero means there is no real or physical PIC associated with the specified interface.

ifChassisPort

ifChassisEntry 3

The number of the port on the PIC card on which the interface is located in the chassis. It is the port number on the PIC card for the specified interface.

Although the number is labeled from 0 and up in the chassis, the return value for this object always starts from 1 according to network management convention. Therefore, a value of zero means there is no real or physical port associated with the specified interface.

ifChassisChannel

ifChassisEntry 4

The channel identifier for the specified interface if it is part of a channelized interface.

Although the channel is numbered from 0 and up in the interface naming, the return value for this object always starts from 1 according to network management convention. For an interface that could not be channelized, this object returns zero.

ifChassisLogicalUnit

ifChassisEntry 5

The logical unit number of the specified interface. It is the logical part of the interface that is configured on the physical or channel part, if any.

Although the logical unit number is numbered from 0 and up in the interface naming, the return value for this object always starts from 1 according to network management convention. For an interface that is really a physical device, this value returns zero.

ifChassisPicIndex

ifChassisEntry 6

The indexes for the Chassis MIB tables. This is the instance index that keys into jnxContentsTable in the Chassis MIB.

For example, the octet string of 8.1.2.0 means a PIC (“ 8&” first digit) at FPC slot 0 (“1–1” , second digit minus one if nonzero) PIC number 1 (“2–1” , third digit) minus one if nonzero port number, whatever (fourth digit currently unused). In turn, this PIC index can be plugged in by the NMS directly after any MIB objects in the jnxContentsTable obtain that PIC object for the specified interface. This object is valid only for interfaces having real and physical PIC cards. Otherwise, it returns an octet string “0.0.0.0.”
