Article ID: KB36999 KB Last Updated: 08 Jun 2021Version: 1.0
Summary:

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.

jtac-lab# load set terminal

[Type ^D at a new line to end input]

set interfaces qf1-rsng22-1:xe-0/0/10 ether-options 802.3ad lacp force-up
load complete

[edit]
jtac-lab# show | compare
[edit interfaces qf1-rsng22-1:xe-0/0/10 ether-options 802.3ad]
+      lacp {
+          force-up;
+      }

[edit]
jtac-lab# commit and-quit

[edit interfaces ae41]
  warning: Missing a Node group prefix   <<<<<<<<<<<
commit complete

Exiting configuration mode

jtac-lab>show configuration interfaces qf1-rsng22-1:xe-0/0/10
description "fn=MRA dd=xz1302p  di=179-T1";
ether-options {
    802.3ad {
        lacp {
            force-up;
        }
        qf1-rsng22:ae10;
    }
}
Cause:

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.

Solution:

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.
