Reserving Uplink Bandwidth
You can reserve and prioritize uplink bandwidth traffic to provide higher QoS for specific applications, traffic or
ports. This is done by applying bandwidth reservation on existing session ACLs. Typically, the bandwidth reservation
is applied for uplink voice traffic.
The following must be noted before you configure bandwidth reservation:
l You must know the total bandwidth available.
l The bandwidth reservation are applicable only on session ACLs.
l Bandwidth reservation on voice traffic ACLs receives higher priority over other reserved traffic.
l You can configure up to three unique priority for bandwidth reservation.
l The bandwidth reservation must be specified in absolute value (kbps).
l Priorities for bandwidth reservation are optional and bandwidth reservations without priorities will be treated
equal.
Understanding Bandwidth Reservation for Uplink Voice Traffic
The voice ACLs are applicable on the voice signalling traffic used to establish voice call through a firewall. When a
voice ACL is executed, a dynamic session is introduced to allow voice traffic through the firewall. This prevents the
re-use of voice ACLs for bandwidth reservation. However, you can create bandwidth reservation rules that can be
applied on voice signalling traffic and also on ports used for voice data traffic. This mechanism filters traffic as per
the security requirements.
Configuring Bandwidth Reservation
You can configure bandwidth reservation ACLs using CLI or the WebUI.
In the WebUI
To configure bandwidth reservation
1. Navigate to Configuration > Advanced Services > All Profiles
2. Under
Profiles
, navigate to AP > AP System Profile. You can create a new AP system profile to configure
bandwidth reservation or edit an existing AP system profile. Under the
Profile Details
page, specify bandwidth
reservation values.
