coIfDwdmFrequency

Module: CISCO-OPTICAL-IF-EXTN-MIB

OID (symbolic): CISCO-OPTICAL-IF-EXTN-MIB::coIfDwdmFrequency

OID (numeric): 1.3.6.1.4.1.9.10.66.1.2.1.1.1

Node type: OBJECT-TYPE

Type: CoDwdmFrequency

Access: read-write

Description: The nominal central frequency associated with this interface, in GHz.

This object is instantiated for interfaces with coIfTypeExtn value of 'wdmChannel' and 'wavelengthTransport'. This object may also be instantiated for optoelectronic interfaces that originate or terminate DWDM wavelengths, including some of the interfaces with coIfTypeExtn value of 'opticalTransponder'.

What is coIfDwdmFrequency?

A read-write value giving the nominal central DWDM frequency (in GHz) assigned to this optical interface, used for interfaces such as WDM channels or wavelength transport ports.

Examples
