I'm trying to configure WAN IPSLA monitoring between Cisco Nexus switches.

On the IPSLA sender I've added the following configuration:

IPSLA sender feature enabled

snmp-server enable traps ip sla

snmp-server host [OpManager_IP] traps version 2c private

On the responder I have "IPSLA Responder feature enabled".

SNMP community is providing RW permissions.

Both devices monitored with OpManager.

No ACLs or firewalls are between OpManager and IPSLA sender.

Destination IP is available.

OpManager IPSLA licenses are OK.

And I still have the following error:

Add monitor failed - Check whether SNMP port and write community are properly configured for the device.

Could you please advice what to do in this situation.
