Description

This article explains how to check the port mode in Satellite device and provides the steps to convert port mode from clustering to extended.

Symptoms

  • Servers connected in satellite device is not working as expected while they connect via uplink interface.
  • Uplink mode should be in extended mode while connecting to the server. However, it detects as clustering.

Solution

By default, default uplink ports act as aclustering port. Refer to Understanding Satellite Device Clustering in a Junos Fusion .

If the devices are part of a satellite device cluster, the default uplink ports cannot be configured as extended ports to pass network traffic.

  • They should have a direct connection to the aggregation device

OR

  • If there is an uplink port policy configured that excludes them from acting as uplink ports.

​Topology:

EX9204 (AD) – Cluster – xe-132/2/2 – server

Use this command to verify the cluster output from the AD:

root# run show chassis satellite-cluster
 
Cluster Name: IDF3
    Number of devices provisioned: 2
    Number of devices present: 2
    Number of devices unprovisioned: 1
    Number of devices misconfig/miwired: 0
    Number of devices online: 2
    Number of devices offline: 1
 
         Device                      Local        Remote       Interface
  Slot   State         Distance      Interface    Interface    State
  132    Online        1   [via 131] xe-132/2/0    xe-131/2/0    present
                                     xe-132/2/1    xe-131/2/1    present
  131    Online        0             et-131/1/0   et-0/0/0     online
                                     xe-131/2/0   xe-132/2/0   present
                                     xe-131/2/1   xe-132/2/1   present
 

From the above output, xe-132/2/0 and xe-132/2/1 are participating in cluster connectivity.

Verify the interface status in satellite device:

root@sd132:~# vty

16447  xe-0/2/2          Clustering    185  0x0000000000000100   Up
 

However, xe-132/2/2 is also in clustering mode which is connected to the server.

Note : Interface name will be xe-0/2/2 while you are verifying the output in that specific SD

Steps to convert the port mode from clustering to extended using uplink port policy:

This uplink port policy is applied in the FPC level. For more details, refer to Configuring an Uplink Port Policy for a Satellite Device Cluster  

set chassis satellite-management cluster IDF3 fpc 132 cluster-policy New
set policy-options satellite-policies port-group-alias Grp1 pic 2 port 0
set policy-options satellite-policies port-group-alias Grp1 pic 2 port 1
set policy-options satellite-policies candidate-uplink-port-policy New uplink-port-group Grp1
 
Note: The above set of command used to specify the clustering ports, remaining port (not specified ports) will act as extended port.

The interface mode changed from clustering to Extended in SD device.
