HP FlexFabric Virtual Switch 5900v Troubleshooting Guide

Flowtable stats: active_count = 2.

If the maximum number of flow tables on a VFE is reached, no new flow table can be created, and

VM communications might be affected. You can wait for flow table aging, or remove vNICs not in

use from the VDS to remove redundant flow tables.

6. If the problem persists, contact HP Support.

Failure to remove part of broadcast traffic

information in the flow table

Symptom

Restart the VCE when there is broadcast traffic, and unbind a vNIC from the VDS. Then execute the dpctl

dump-flows command on the VFE to display flow table information. Part of broadcast traffic information

still exists in the flow table.

Solution

This symptom occurs because flow table information before the VCE is restarted cannot be saved on the

VFE after the VCE is restarted. When you unbind a vNIC, the corresponding flow table on the VFE

cannot be removed.

To resolve the problem:

1. Wait until the flow table ages out, because the flow table on the VFE has an aging timer.

2. If the problem persists, contact HP Support.

Incorrect host information caused by changing the

IP address of a host in VDS

Symptom

Change the IP address of a host, and display all hosts on the VDS. The system displays an error message:

"Incomplete host data.".

Solution

This symptom occurs because you change the IP address of a host when the host has been added to a

VDS.

To resolve the problem:

1. Remove the host from the VDS, and add it to the VDS again.

Or restart the VCE.

2. If the problem persists, contact HP Support.
