Configuring Uplink Port Policies on a Junos Fusion

 

Ports on a satellite device that can be used as uplink ports are called candidate uplink ports. Each satellite device model has a set of default candidate uplink ports that the device can use to connect to the aggregation device and, in the case of a satellite device cluster, to other satellite devices. You can override the default set of candidate uplink and clustering ports by defining a candidate uplink port policy for the device.

To configure a candidate uplink port policy, you must first configure an uplink port group. The uplink port group defines a set of candidate uplink ports on a satellite device. Uplink port groups are assigned to candidate uplink port policies, which are assigned to satellite devices.

Note

The candidate uplink port policy must include at least one port from the default candidate uplink port. Otherwise, the aggregation device will not be able to communicate with the satellite device in order to provision the satellite device with the uplink port policy.

To configure an uplink port policy:

  1. Create an uplink port group:
    [edit policy-options satellite-policies]

    user@switch# set port-group-alias port-group-alias-name
  2. Configure the PICs that contain ports to be identified as candidate uplink ports:
    [edit policy-options satellite-policies port-group-alias port-group-alias-name]

    user@switch# set pic pic-number
  3. Configure the ports on the PICs to be identified as candidate uplink ports:
    [edit policy-options satellite-policies port-group-alias port-group-alias-name pic pic-number]

    user@switch# set port [port-number | port-number-range | all]
  4. Create a candidate uplink port policy:
    [edit policy-options satellite-policies]

    user@switch# set candidate-uplink-port-policy policy-name
  5. Assign the uplink port group to the candidate uplink port policy:
    [edit policy-options satellite-policies candidate-uplink-port-policy policy-name]

    user@switch# set uplink-port-group group-name

Configuring an Uplink Port Policy for a Satellite Device Cluster

Candidate uplink port policies for a satellite device cluster can be applied at the cluster level, FPC level, or globally. Policies configured at the FPC-level take precedence over cluster and global policies. Policies configured at the cluster level take precedence over global policies.

  1. Follow steps 1-3 in the procedure above to create an uplink port group.
  2. Configure a candidate uplink port policy for a satellite cluster at the cluster level, FPC level, or global level:
    • To configure a policy at the cluster level:

      [edit]

      user@switch# set chassis satellite-management cluster cluster-name cluster-policy satellite-port-policy-name
    • To configure a policy at the FPC level:

      [edit]

      user@switch# set chassis satellite-management cluster cluster-name fpc fpc-number cluster-policy satellite-port-policy-name
    • To configure a policy at the global level:

      [edit]

      user@switch# set chassis satellite-management cluster-policy satellite-port-policy-name
  3. Assign the uplink port group to the candidate uplink port policy:
    [edit policy-options satellite-policies candidate-uplink-port-policy policy-name]

    user@switch# set uplink-port-group group-name
