hcxUpstrmRpmControl

Module: COM21-HCXRX-MIB

OID (symbolic): COM21-HCXRX-MIB::hcxUpstrmRpmControl

OID (numeric): 1.3.6.1.4.1.1141.2.31.1.1.13

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: Defines RPM control. This attribute is only applicable in the case of an RXM card. For the RX card this attribute will be read-only with a value of notSupported. If the RPM is present then the control shall be validated against the physical configuration. If an attempt is made to place the RPM in 8 port mode but it is physically configured for 4 port, then an error response shall be return. Default for RxM is enable8Port. Option notSupported is unavailable for RxM.

What is hcxUpstrmRpmControl?

This read-write INTEGER selects notSupported, enable4Port, or enable8Port for an RXM card's Remote Power Module, and the description says a plain RX card reports this as read-only notSupported, while setting an unsupported port count against the RPM's physical wiring produces an error. An admin uses this to match the RPM's logical port-count mode to how it is physically cabled. For example, an admin configures hcxUpstrmRpmControl to enable8Port only after confirming the attached RPM hardware is physically wired for 8-port operation, since setting it against a 4-port RPM triggers an error.
