cXdslModeSpectrum

Module: CISCO-XDSL-LINE-MIB

OID (symbolic): CISCO-XDSL-LINE-MIB::cXdslModeSpectrum

OID (numeric): 1.3.6.1.4.1.9.9.204.1.3.1.2

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: The value of this object specifies the spectrum mode of
this interface. The interface will stay in spectrum mode
until this object is set to disabled.
The modes will inhibit the service on that line.
Not all spectrum modes are avaiable for all types of modems.
The modes translate as follows:

sdsl & shdsl
------------
spectrum1 = tx-1           spectrum2 = tx-3
spectrum3 = tx+1           spectrum4 = tx+3
spectrum5 = spec2PT        spectrum6 = spec4PT

dmt
---
spectrum1 = reverb         spectrum2 = medley
spectrum3 = pilot          spectrum4 = not supported 
spectrum5 = not supported  spectrum6 =  not supported

cap
---
spectrum1 = 136k           spectrum2 = 340k 
spectrum3 = 680k           spectrum4 = 952k
spectrum5 = not supported  spectrum6 = not supported
 

What is cXdslModeSpectrum?

This read-write object selects a specific spectrum (frequency allocation) mode for this xDSL interface, and the desc notes the interface remains in that mode, with service inhibited, until this object is set back to disabled. It also cautions that not all of the six available spectrum options are supported on every modem type, and their meaning varies by modem type such as SDSL and SHDSL. For example, an admin testing spectral compatibility on an SHDSL line would need to consult the modem-specific spectrum mapping before choosing a spectrumN value here, since the same numeric option means something different on a different DSL technology.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.9.9.204.1.3.1.2
snmpwalk -v2c -c public <target> CISCO-XDSL-LINE-MIB::cXdslModeSpectrum

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.9.9.204.1.3.1.2.1
snmpget -v2c -c public <target> CISCO-XDSL-LINE-MIB::cXdslModeSpectrum.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.9.9.204.1.3.1.2.1 i <value>
