18 Connecting to the IP Network
After powering up the Mediant 8000, you need to connect the Media Gateway to the
IP network. Take the following steps to complete this task:
Prepare two external fully-redundant Layer 3 switches or routers
Configure Basic IP Network Parameters of SC boards (SC boards are used for
performing chassis management and configuration tasks)
Connect IP network cables
18.1 Preparing the External Layer Switches or Routers
The Mediant 8000 must be connected to two external Layer 3 Switches or Routers
that are configured for fully redundant operation via the use of HSRP (Hot Standby
Router Protocol) or VRRP (Virtual Router Redundancy Protocol) protocols. See
'Connecting the Mediant 8000 to the IP Network' on page 217 for details.
Note: In a temporary lab environment, it is possible to connect uplinks of both ES
boards to the same external Layer 3 Switch or Router. However such a
configuration does not provide a redundant IP network connection for the Mediant
8000 and therefore should not be used for live deployments.
For an initial installation of the Mediant 8000 in a customer environment, an IP subnet
that doesn’t use VLAN tagging is required. This subnet will be used as an OAM subnet
during the initial installation and/or basic software configuration. The Mediant 8000,
the EMS server and client machines should be connected to this subnet during the
initial installation and/or configuration. When the installation and/or configuration has
completed and connectivity between the Mediant 8000 and the EMS is properly
established, more complex IP network configurations may be provisioned on
theMediant 8000. See 'Connecting the Media Gateway to the IP Network' on page 178
for more details.
If the Mediant 8000is installed on a site that lacks a proper IP subnet without VLAN
tagging, proceed with the rest of this chapter and then perform installation and/or
basic configuration, using the RS-232 serial console to connect to the CLI interface.
As soon as the Mediant 8000 software is up and running, use the procedures
described in 'Recovering the OAM VLAN Settings' on page 842 to configure the VLAN
tag for the OAM subnet on the Mediant 8000.
