Application Overview
Before using Managed Media Converter in your network, decide the following:
•
How many Managed Media Converter units will you use?
•
How do you want to manage the Managed Media Converters?
•
Will you define VLAN IDs?
How many Managed Media Converter units will you use?
•
Two for a Host/Remote application-allows IP-less management providing greater security
•
One for a single solution application
How do you want to manage Managed Media Converter?
You can manage Managed Media Converter through any of its three ports (and any
combination thereof) or from the chassis. Using the EXT MGMT/OPTICS (or UPLINK) port
combination separates management traffic from the data and provides the highest level of
security.
Will you define VLAN IDs?
When you want to use VLAN traffic with specific tags on any/all of the DATA ports, you will
need to disable Transparency and define VLAN IDs (refer to
VLAN Configuration
section).
When you want to use both VLAN tagged and untagged traffic, enable Transparency.

Creating SNMP Community Strings
The default community string is named “public” and has read/write access. It is recommended
that you create custom community strings (with read-only access for general use and another
with read/write access for the administrator) and test them before deleting “Public”. To create
a new community string, go to the main configuration screen and press
C
. Enter the name of
the new community (up to 16 characters, no spaces) and press
Enter
. Then type one of the
following to assign the community string’s access rights:
•
R
= read-only access •
W
= read/write access •
Enter
= abort
Deleting SNMP Community Strings
To delete all community strings and start over, press
U
. You will then be prompted, “Are you
sure you want to delete all community strings?” Press
Y
to proceed,
N
to abort. Press
Enter
to
finish.
This function will delete all community strings. If you want to be able to selectively delete
community strings, use iConfig to configure your device.
Assigning SNMP Trap Destinations
Traps are sent by the manageable device to a management PC when a certain event takes
place. To enter a trap destination, press
T
. You will then be asked to “Enter a New IP
Address.” Type the IP address of the destination device and press
Enter
. Then type the name
of the community string (that the destination device has been configured to accept) and press
Enter
. Select whether the trap is for SNMP version 2c and press
Enter
. This function enables
all of the device traps. When you want to selectively activate and de-activate traps, use
iConfig to configure your device.
Supported traps include: Link Down, Link Up, Cold Start, Warm Start, Last Gasp, and
Authentication Failure.
When deployed in pairs, Managed Media Converter also supports the following traps:
•
Remote Unit Lost
•
Remote Unit Found
•
Far End TX Link Up
•
Far End TX Link Down
•
Remote Unit Cold Start
•
Remote Unit Warm Start
Removing SNMP Trap Destinations
To remove all trap destinations, press
K
. You will then be prompted, “Are you sure you want
to delete all trap destinations?” Press
Y
to continue, press
N
to abort. Press
Enter
to finish.
This function will delete all trap destinations. If you want to be able to selectively delete trap
destinations, use iConfig to configure your device.
