DCNM fabric out-of-sync due to configuration mismatch with snmp trap default port configured with snmp_server_host_trap template
DCNM version 11.3.1 snmp trap configured with default port
Workaround1: Disable "Enable DCNM as Trap Host" in the fabric settings advance tab which will remove the dcnm default intent and then use switch_freeform to have custom command of snmp-server host. If community string or UDP port is different, make sure to update the server properties also. Workaround2: Create custom template, remove udp-port variable and adjust CLI configuration
Example of custom template: ##template variables # Copyright (c) 2018-2019 by Cisco Systems, Inc. # All rights reserved. @(IsMandatory=true, DisplayName="IP Address", Description="IPv4/v6 Address Of SNMP Notification Host") ipAddressWithoutPrefix IP; @(IsMandatory=true, DisplayName="SNMP Version", Description="SNMP Version To Use For Notification Messages") enum VER { validValues=1,2c,3; defaultValue=2c; }; @(IsMandatory=true, DisplayName="Community String or SNMPv3 user name", Description="Max Size:32") string CS { defaultValue=public; minLength = 1; maxLength = 32; }; ## ##template content snmp-server host $$IP$$ traps version $$VER$$ $$CS$$ ## PSIRT Evaluation: The Cisco PSIRT has evaluated this issue and determined it does not meet the criteria for PSIRT ownership or involvement.
