coIfXcvrLaserFrequencySpacing

Module: CISCO-OPTICAL-IF-EXTN-MIB

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

OID (numeric): 1.3.6.1.4.1.9.10.66.1.4.1.1.4

Node type: OBJECT-TYPE

Type: Unsigned32

Access: read-write

Description: The difference in frequency between successive bits in coIfXcvrLaserFrequencyBitmap. This is typically the frequency difference between adjacent channels in the DWDM system.

What is coIfXcvrLaserFrequencySpacing?

Sets the frequency spacing (typically the DWDM channel spacing) between consecutive bits in the tunable laser's frequency bitmap.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.9.10.66.1.4.1.1.4
snmpwalk -v2c -c public <target> CISCO-OPTICAL-IF-EXTN-MIB::coIfXcvrLaserFrequencySpacing

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.9.10.66.1.4.1.1.4.1
snmpget -v2c -c public <target> CISCO-OPTICAL-IF-EXTN-MIB::coIfXcvrLaserFrequencySpacing.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.9.10.66.1.4.1.1.4.1 i <value>
