Description

While committing the Link Aggregation Control Protocol (LACP) configuration on one AE interface's child member, another AE interface in the group may display the warning "Missing a Node group prefix."

This article describes how to resolve this warning message.

Symptoms

On a QFabric node, while committing configuration on a child member of one AE interface, another AE interface in the group may display the following warning message:

jtac-lab# commit and-quit
[edit interfaces ae41]
  warning: Missing a Node group prefix
commit complete
Exiting configuration mode
The AE interface, which shows a warning message, has the following configuration at the Stratus Fabric Controller (SFC).
 ae41 {
         description "fn=DIC dd=cfpm-rzud-6101 di=1649720-bond1";
         metadata NW-NG-0:ae41;
         mtu 9150;
         mac f5:b9:2e:b9:e0:79;
         aggregated-ether-options {
             lacp {
                 active;
                 periodic fast;
             }
         }
         unit 0 {
             family ethernet-switching {
                 port-mode trunk;
                 vlan {
                    members V2352---qfabric;
                 }
             }
         }
     }

When the above configuration exists on an interface and when you apply the following configuration this interface, the "Missing a Node group prefix" warning message is displayed (the warning message will be seen for all configuration commits) although the commit succeeds.

    }
}

Solution

A missing node group prefix (such as NW-NG-0, qf1-rsng1-1, etc) at the interface configuration of QFabric results in this warning message being output.

From the QFabric SFC, the AE interfaces should have the corresponding node prefix added to it as shown below:

 NW-NG-0:ae41 {
         description "fn=DIC dd=cfpm-rzud-6101 di=1649720-bond1";
         metadata NW-NG-0:ae41;
         mtu 9150;
         mac f5:b9:2e:b9:e0:79;
         aggregated-ether-options {
             lacp {
                 active;
                 periodic fast;
             }
         }
         unit 0 {
             family ethernet-switching {
                 port-mode trunk;
                 vlan {
                    members V2352---qfabric;
                 }
             }
         }
     }

When the corresponding node group is added, the warning message "Missing a Node group prefix" should be cleared and not appear again.
