Mediant 8000
Problem Possible Cause(s) Actions to Take See:
Duplicate IP address Verify that no other equipment uses
the same IP address as the one
assigned to the SC board.
Connect to the SC board’s CLI
interface via the RS-232 serial
console and check for "duplicate IP
address" messages (wait a few
minutes to see if the messages are
recorded).
If the "duplicate IP address"
problem exists, do one of the
following:
locate and reconfigure/remove the
faulty external equipment
update the basic SC's network
configuration (redefine the IP
addresses).
'Configuring the
Basic IP Network
Parameters of
SC Boards' on
page 117
No communication
with the Media
Gateway
(ping to the Global
SC's IP does not
work)
Media Gateway
software is not
running on either SC
board
Media Gateway software starts
automatically after the SC board is
rebooted.
If this does not help – one of the
following scenarios must have
occurred:
Media Gateway software is not
installed on the SC board –
install it
Basic IP network parameters of
SC board were altered (option 1
in install command), but the
system configuration (options 3
or 4) were not run – run the
missing options.

Media Gateway
software on the
SC Board' on

Parameters of
SC Boards' on

No communication
with the Media
Gateway
(The CLI connection
to the Global SC's
IP address works;
however the
connection to
SNMP does not)
Wrong SNMP
manager settings
Ensure that the SNMP protocol
configuration on the SNMP
manager matches the Mediant 8000
configuration. For the SNMP v2
protocol, ensure that the correct
SNMP community strings are
configured. For the SNMP v3
protocol, ensure that the correct
privacy and security settings are
configured.
