VLAN Data experiencing slow performance from Dual VLAN setup

[Imaginet]

Hi Guys,

Here is what the problem that I encounter:

Data VLAN experiencing slow performance due to voice vlan setup.

We are using panasonic phones (KX-NT511) and also have manually setup the VLAN settings.

We are not experiencing slow performance for VLAN voice.

Troubleshooting steps taken:

Connection from dual VLAN switchport with PHONE (tagged voice and untagged data) , slow performance for vlan Data.

Connection from dual VLAN switchport without PHONE (tagged voice and untagged data) , slow performance for vlan Data

Connection from only untagged VLAN data , better performance.

here is our config for the switch:

Running configuration:

Your switch config looks fine.

Where is the traffic being routed?

What are the stats (including errors) on the interfaces A1 & A2?

Double-check your phone config.
