732 OMNM 6.5.3 User Guide
SNMP v2c only supports read operations, not write. SNMP v3 supports both read and write, but
not SNMP v3 informs. To manage Aruba devices you must use SNMP v2 or v3. Up to Aruba
OS3.1.1.2, SNMPv2c (read-only) and v3 (read-write) are recommended. SNMP v1 does not work
correctly.
NOTE:
Although SNMP handles the bulk of the communication with this device, and you must supply the correct
SNMP authentication information, some information comes through telnet interaction, so you must
supply telnet/SSH authentication too for all device interactions to work correctly.
Backup and Restore
You can backup or restore text files that reflect the Startup Config, and Running Config as well as
backup/restore of a binary
Flash memory for the selected device. You can compare, store, view and
version the text files, and can restore either text or flash memory to the device if you have the File
Management option installed.
Because the Aruba mobility controller's flash memory backup is a compressed, binary
.tar.gz
file, the displayed Current Config is not always textual. The flash file is binary, so you cannot view
it as text. Nevertheless, you can restore it as long as the backup file has the extension of
.tar.gz
Using this application to backup the flash automatically creates the file with this extension.
Avaya Device Prerequisites
You must do the following for the device driver to function correctly with Avaya devices. Whether
you use RTCP or not, do the bullet point setup steps outlined in
Setting Up RTCP on page 732,
below.
Cut-Through
Avaya Communication Manager uses a special port for telnet sessions. To use the Telnet Cut-thru
feature in this software, you must modify the port. You can do this during the discovery process by
creating a Telnet authentication object and entering port 5023. Alternatively, once you install
Communication Manager, open it from the Resources screen, select the Authentication tab and
create a new Telnet management interface with port 5023. When you initiate a Telnet cut-thru
session, Customer Manager asks for an emulation type. Select type 4410.
Setting Up RTCP
The following describes setting up RTCP with Avaya devices. Do this on the Avaya Media Server
with the Media Server's Management Web Interface using a browser (for example, Internet
Explorer) to access the IP address of the media server. For an S8300, S8400, S8500 use the server’s
IP address. For the S87xx, use the active server IP address—not server A or server B but the active
server address. When accessing the web manager, after logging in, navigate to the Maintenance
Web Page to see the following menu choice:.
NOTE:
When changing SNMP settings Avaya recommends stopping and restarting the agent.
• Enable SNMP v2 on the device (under Alarms > SNMP Traps )
• Ensure the SNMP community strings match on the authentications you have configured and
on the device (
Alarms > SNMP Agents ).
