Technical Tip: Understanding error message 'node_check_object fail! for interface-name'

[achu]

Description	This article describes the error message 'node_check_object fail! for interface-name” when adding port 7 in an existing FortiLink interface from CLI. riz-kvm43 # config system interface Iriz-kvm43 (interface) # edit "test" Iriz-kvm43 (test) # show config system interface     edit "test"         set vdom "root"         set fortilink enable         set ip 10.10.10.1 255.255.255.0         set allowaccess ping fabric         set type aggregate         set member "port3" "port4" "port5" "port6"         set device-identification enable         set lldp-reception enable         set lldp-transmission enable         set snmp-index 15         set auto-auth-extension-device enable     next end Iriz-kvm43 (test) # set member "port3" "port4" "port5" "port6" "port7" node_check_object fail! for interface-name port7 value parse error before 'port7' Command fail. Return code -651
Scope	FortiOS.
Solution	In this scenario, the user is trying to configure port7 to be a member of the FortiLink interface named 'test'. The user is unable to add port7 as it is already configured in a software switch. To verify that port7 is added in a software switch: Iriz-kvm43 # show full | grep -f port7 config system switch-interface     edit "lan"         set vdom "root"         set member "port7" <---         set type switch         set intra-switch-policy implicit         set mac-ttl 300         set span disable     next end The following command can also check the References for port7:  diagnose sys cmdb refcnt show system.interface.name port7 entry used in table system.virtual-switch:name 'lan' entry port:name 'port7' (From 'global') To resolve this issue, port7 should be removed from the software switch interface. Iriz-kvm43 # config system switch-interface     edit lan Iriz-kvm43 (lan) # unset member Iriz-kvm43 (lan) # end Iriz-kvm43 # show system switch-interface config system switch-interface     edit "lan"         set vdom "root"     next end Related article: Technical Tip: How to Check Referenced Objects
