Workarounds

CNA: The workaround is to disable gNMI Set requests. This can be done by applying per RPC authorization and ensuring no user is authorized to run the OpenConfig.Set command. switch(config-gnmi-transport-default)#show management api gnmi transport grpc default authorization requests Alternatively, TLS can be disabled: switch(config-gnmi-transport-default)#no ssl profile Alternatively, the OpenConfig agent can be disabled entirely: switch(config-gnmi-transport-default)#no management api gnmi
