hwDefType

Module: CTATX-MIB

OID (symbolic): CTATX-MIB::hwDefType

OID (numeric): 1.3.6.1.4.1.97.3.1.2.1.4

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-only

Description: The module type defined for the slot. Certain pre-defined relationships exist. Slot 1 always contains the Packet Processing Engine board. Slots 2-6 are either unoccupied, or contain IOM boards. Slot 7 is either unoccupied or contains the Turbo processor board. If hwDefType does not match hwType, then the module will not be used, regardless of the value of hwUseMod. Note that hwDefType can only be changed by rebooting the ES/1.

What is hwDefType?

This read-only INTEGER, changeable only by rebooting the device, defines the module type expected for a slot from values like vacant, unknown, packet-processing-engine, turbo, and various IOM types, with fixed slot relationships such as slot 1 always holding the Packet Processing Engine; if it doesn't match the module's actual hwType, the module won't be used. An admin uses this to confirm the expected module type configured for a slot matches what is physically installed there. For example, a slot 3 hwDefType of csma-iom that doesn't match a physically installed FDDI IOM's actual hwType would explain why that module is being ignored despite being present.
