Configuring Firewall Settings for Voice and Video ALGs

After configuring the user roles, you must configure the firewall settings for the voice and video Application-Level Gateways (ALGs) to pass the traffic securely through the Dell devices.

You can use the WebUI or CLI to configure the firewall settings for the ALGs.

In the WebUI

1.Navigate to the Configuration > Advanced Services > Stateful Firewall page.

2.Enable the firewall settings for the ALGs:

a.Select the Stateful SIP Processing check box for the SIP ALG.

b.Select the Stateful H.323 Processing check box for the H.323 ALG.

c.Select the Stateful SCCP Processing check box for the SCCP ALG.

d.Select the Stateful Vocera Processing check box for the Vocera ALG.

e.Select the Stateful UA Processing check box for the NOE ALG.

In the CLI

To enable the firewall settings for the SIP ALG:

(host) #configure terminal

(host) (config) #no firewall disable-stateful-sip-processing

To enable the firewall settings for the H.323 ALG:

(host) (config) #no firewall disable-stateful-h323-processing

To enable the firewall settings for the SCCP ALG:

(host) (config) #no firewall disable-stateful-sccp-processing

To enable the firewall settings for the Vocera ALG:

(host) (config) #no firewall disable-stateful-vocera-processing

To enable the firewall settings for the NOE ALG:

(host) (config) #no firewall disable-stateful-ua-processing

Additional Video Configurations

You can configure ArubaOS to reliably and efficiently stream video traffic over wireless LAN (WLAN). This new method allows you to stream video traffic reliably without much loss. To ensure that video data is transmitted reliably dynamic multicast optimization techniques are used.

Although the dynamic multicast optimization conversion generates more traffic, that traffic is buffered by the AP and delivered to the client when the client emerges from power-save mode.

Configuring Video over WLAN enhancements

To configure video over WLAN enhancements, do the following:

Enable WMM on the SSID profile.

Enable IGMP proxy or IGMP snooping.

Configure an ACL to set a DSCP value same as the wmm-vi-dscpvalue in the SSID profile for prioritizing the multicast video traffic.

Enable dynamic multicast optimization under VAP profile.

Configure the dynamic multicast optimization threshold—The maximum number of high throughput stations in a multicast group. The optimization will stop if the number exceeds the threshold value.
