Buffer profiles for VoIP on FastIron stackable devices
NOTE
Configuring buffer profiles for VoIP traffic is not supported on FastIron X Series devices.
Default buffer settings are currently optimized for 1 GbE-to-1 GbE traffic. Configuring VoIP buffer
profiles adds buffer profiles for 1 GbE-to-100 Mbit traffic, simplifying configuration and improving
performance.
VoIP profiles allows you to configure a pre-defined set of buffers and descriptors for the priority 0
and 7. These profiles support VoIP traffic that uses priority 7, with 10 Mbps or 100 Mbps uplink
ports and 1000 Mbps downlink ports.
NOTE
In previous software versions, you could manually configure buffers and descriptors using qd
commands. Buffer profiles for VoIP cannot coexist with qd commands. You may use buffer profiles
for VoIP or qd command, but not both at the same time.
Configuring buffer profiles for VoIP
To configure predefined buffers, enter a command similar to the following.
Brocade#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).
NOTE
Only FGS and FLS models support the buffer-profile port-region <num> voip downlink 100 uplink
1000 command. FCX and ICX models do support this command.
Deleting buffer profiles for VoIP
To delete an existing buffer profile configuration, use the no form of the command.
Brocade#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 on 1Gbps fiber connections
NOTE
Remote fault notification (RFN) is only available for 1 Gbps Ethernet Fiber ports. It is not available
for 10/100 ports and Gbps Ethernet Copper ports. This feature is not available on ICX 6430and ICX
6450 devices.
For fiber-optic connections, you can optionally configure a transmit port to notify the receive port on
the remote device whenever the transmit port becomes disabled.
