Cisco Cisco Prime Optical 9.3 Technical References

When setting up an SNMPv1 or SNMPv2 trap destination:

Delete the GNE and ENE’s SNMP trap destinations before performing GNE-ENE role changes. 
After a GNE-ENE role switch is complete, add the new SNMP trap destinations according to the 
new GNE-ENE roles.

If the ENE does not contain the GNE’s SNMP community string, mark the ENE as Out of Service 
and then In Service.

Do not use an ONS 15600 as the GNE and an ONS 15454 as the ENE.

The GNE-ENE SNMP community string must be Public.

Prime Optical supports SNMPv3 on CTC-based release 9.3.1 NEs. (SNMPv3 is not supported on 
ONS 15305, ONS 15305 CTC, or ONS 15327 NEs.)

As is the case for SNMPv1 and SNMPv2, to support SNMPv3, NEs with ML-series cards must have a 
valid SNMP configuration to guarantee correct initialization and management of Layer 2 parameters. If 
the SNMP configuration is invalid, the Audit Log records a resynchronization failure.
