Avaya ERS4826GTS Manual

Ethernet Switch
Setup
for Q-SYS
Avaya ERS4850 Series (Models ERS4826GTS, ERS4826GTS-PWR+, ERS4850GTS,
and ERS4850GTS-PWR+)
Revision 1.1—21 January 2016
Firmware used: 5.8.0.1 Software used: v5.8.1.029
Configuring the Switch
Assign an IP address, enable the optional web interface, and assign
QoS
1. Using a standard network switch console or “rollover” cable, connect the serial port on the
PC, or a USB-to-serial adapter, to the console port on the front of the switch.
2. Open a terminal emulator such as HyperTerminal or PuTTY and connect to the switch
using the following serial settings: 9600, N, 8, 1; no flow control.
If the switch does not respond by initiating a terminal session, try turning it off and on again.
As the switch boots up, the terminal emulator window should start displaying log
messages.
3. When the AVAYA logo appears, it will also display a status area indicating the switch
model, hardware version, firmware version, and the software version.
4. Press
Ctrl+Y
. A prompt showing the switch model number will appear—for example,
4850GTS-PWR+>
will appear. (Other models will display accordingly; for this setup guide,
we will use the 4850GTS-PWR+ as an example.)
5. Type enable and then press
Enter
.
6. The prompt will change to
4850GTS-PWR+#
Type
configure terminal
and press
Enter
.
7. The message “Enter configuration commands, one per line. End with CNTL/Z.” will appear,
followed by the configuration-mode prompt,
4850GTS-PWR+(config)#
The next step is to configure the switch’s intended IP address and subnet. Type
ip address xxx.xxx.xxx.xxx yyy.yyy.yyy.yyy

(where “xxx.xxx.xxx.xxx” is the intended IP address and “yyy.yyy.yyy.yyy” is the intended
subnet mask) and then press
Enter
.
Note: If the switch will reside in a part of the network that is inaccessible to the computer
except through a gateway, you must add the gateway’s IP address to this command. (This
is not a common situation.) In this case, you would type
ip address xxx.xxx.xxx.xxx yyy.yyy.yyy.yyy zzz.zzz.zzz.zzz
(where zzz.zzz.zzz.zzz is the optional gateway address) and then press
Enter
.
8. Enabling the web interface is optional. To do so, type
web-server enable
and press
Enter
.
9. Next, set the QoS parameters for Q-LAN audio and PTP packets with the following sets of
commands (you may copy and paste from the text below):
At the prompt, type
qos traffic-profile classifier name "QLAN_Audio" addr-type ipv4
ds-field 34 protocol 17 dst-port-min 6517 dst-port-max 7030
update-dscp 46 update-1p 6 eval-order 1 drop-out-action enable
and then press
Enter
.
Next, type
qos traffic-profile classifier name "QLAN_PTP" addr-type ipv4
ds-field 46 protocol 17 dst-port-min 319 dst-port-max 320
update-dscp 46 update-1p 6 eval-order 1 drop-out-action enable
and then press
Enter
.
10. The next step is to add traffic profiles to individual ports that host Q-LAN devices, so their
data packets are steered into Avaya’s “Premium Queue.” QSC recommends not applying
these profiles to ports that belong to other VLANs, so it often would not be appropriate to
apply them to the entire switch. If a port uplinks to another Avaya switch, for example, it is
better to let them honor their own IP precedence. In the commands below substitute the
port number or numbers where it says “port number(s)”; use a hyphen to designate a range
of port numbers, such as “1-3” for 1 through 3.
At the prompt, type
qos traffic-profile set port port number(s) name "QLAN_Audio" track-
statistics aggregate
and then press
Enter
.

Then type
qos traffic-profile set port port number(s) name "QLAN_PTP"
track-statistics aggregate
and press
Enter
.
11. Configuration is done. So exit configuration mode and save the settings with these
commands.
At the prompt, press
Ctrl+Z
(or type
exit
and then press
Enter
).
Next, type
save config
(or write mem)
and press
Enter
.
12. The switch is now correctly configured to properly prioritize Q-SYS traffic in an Avaya
enterprise QoS environment.
Notes: How to set the switch to factory default configuration
If you have “Enable” access:
1. At the prompt, type
en
and then press
Enter
.
2. Type
boot default
and press
Enter
.
3. At the question
Reboot the unit(s) (y/n)?
press
Y
.
4. The switch will reboot with the factory default settings. This may take a couple minutes.
If you do not have your credentials or have lost them:
1. Connect the computer to the switch’s console port, using settings 9600, 8, N, 1. Open
your terminal emulation program.

2. Turn the switch off and on again to reboot it.
3. When the first line of the diagnostic tests appears, press
Ctrl+C
.
4. A menu will appear listing a number of options. Press
I
to initialize the switch and load its
default settings into its configuration.
5. Then press
A
to run the Agent code, which will complete the initialization and automatically
reboot the switch.
