## Symptoms

- * Intermittent traffic outages may occur a few minutes after you add additional VLANs on an Orchestrator MHO-175 Uplink interface (that is assigned to the Maestro Security Group), or after a policy installation onto the Maestro Security Group.

  **Notes:**
  * There are more than 250 VLANs on an uplink interface that is assigned to the Security Group.
  * Traffic on other uplink interfaces that have fewer than 250 VLANs passes as expected.
* Packet capture on the Security Group Members may not show incoming traffic that arrives through this Uplink interface.

## Cause

Orchestrator incorrectly handles the newly created VLANs when there are more than 250 VLANs configured on the same uplink interface.

## Solution

This problem was fixed. The fix is included in:

* [Jumbo Hotfix Accumulator for R81.20](https://sc1.checkpoint.com/documents/Jumbo_HFA/R81.20/Default.htm) starting from Take 26
* [Jumbo Hotfix Accumulator for R81.10](https://sc1.checkpoint.com/documents/Jumbo_HFA/R81.10/Default.htm) starting from Take 95

If you choose not to upgrade, [Contact Check Point Support](https://www.checkpoint.com/support-services/contact-support/) to get a Hotfix for this issue.

A Support Engineer will make sure the Hotfix is compatible with your environment before providing the Hotfix.

For faster resolution and verification, collect these:

1. The [CPinfo](https://supportcenter.checkpoint.com/supportcenter/portal?eventSubmit_doGoviewsolutiondetails=&solutionid=sk92739) file from the Management Server.
2. The output of the "`asg info`" command from the Maestro Security Group.
3. The output of the "`asg_provision`" command from the Maestro Security Group.

**Hotfix installation instructions:**   
Refer to [sk168597 - How to install a Hotfix](https://supportcenter.checkpoint.com/supportcenter/portal?eventSubmit_doGoviewsolutiondetails=&solutionid=sk168597).

<br />

This**workaround**is available:

1. Connect to the command line on each Maestro Orchestrator on each Site in this environment.
2. Log in to the Expert mode.
3. Restart the *orchd* service:  
   `service orchd restart`

**Warnings:**

* **No traffic flows through the Quantum Maestro Orchestrator until the '*orchd*' services restarts.**
* **If you do not install the Hotfix, the issue will occur again when you add a VLAN and install policy.**
