Generic buffer profiles on PowerConnect Stackable devices
Default buffer settings are currently optimized for 1 GbE-to-1 GbE traffic. This feature adds buffer
profiles for 1 GbE-to-100Mbit traffic, simplifying configuration and improving performance.
This feature allows users to configure a pre-defined set of buffers and descriptors for priority 0 and
7. The buffer profile supports VoIP traffic that uses priority 7, with 10/100 uplink ports and 1000
downlink ports.
NOTE
In previous versions, users could manually configure buffers and descriptors using QD commands.
This feature cannot co-exist with QD commands. You may use one or the other, but not both types
at the same time.
Configuring buffer profiles
To configure predefined buffers, enter a command similar to the following.
PowerConnect#buffer-profile port-region 0 voip downlink 100 uplink 1000
Syntax: [no] buffer-profile port-region <num> voip downlink 100 uplink 1000
NOTE
The port-region num can be either 0 (ports 0/1/1 to 0/1/24) or 1 (ports 0/1/25 to 0/1/48).
Deleting buffer profiles
To delete an existing buffer profile configuration, use the [no] form of the command.
PowerConnect#no buffer-profile port-region 0 voip downlink 100 uplink 1000
Syntax: no buffer-profile port-region <num> voip downlink 100 uplink 1000
Remote Fault Notification (RFN) on 1G fiber connections

Gbps Ethernet Copper ports.
