11.0 Configuring In-band Access to the A/DMM
This section describes how to configure in-band access to
the A/DMM. In-band access allows you to manage the
CoreBuilder 5000 hub from a remote terminal or Simple
Network Management Protocol (SNMP) manager, as
shown in the figure on the next page.
The Network Monitor Card (NMC) provides network
connectivity for the A/DMM. The NMC is a daughtercard
that installs on a DMM-EC or media module.
To configure in-band access to the A/DMM:
1
If the hub does not have an NMC installed, install one.
Install the NMC on a media module or on a DMM-EC,
and then install the module in the hub.
2
Log in to the A/DMM using a terminal connected to one
of the serial ports. The default login name is
lowercase) with a blank password. For example:

5
Use the SET PORT command to assign a port to a
network. For example:
CB5000> set port 8.5 network ethernet_2
6
Use the SHOW INTERFACE command to verify that the
operational status of the interface (NMC) for the
selected network is up.
If the operational status is not up, use the SET MODULE
INTERFACE command to enable the interface. For
example:
CB5000> set module 4.2 interface enable
7
Set the IP subnet mask for the selected network. For
example:
CB5000> set ip subnet_mask ff.ff.ff.0 ethernet_2
8
Set the IP address for the selected network. For
example:
CB5000> set ip ip_address 155.104.10.2 ethernet_2
9
Set the A/DMM IP default gateway for the selected
network. For example:
CB5000> set ip default_gateway 155.104.10.7
ethernet_2
3
Select a backplane network to use for the in-band
connection. The examples in this procedure use
ethernet_2.
4
Make sure that the device that you plan to use for
remote management has connectivity to the selected
network.
For example, you can assign a media module port to the
selected network and connect the port to a router that
has connectivity to your SNMP management
workstation.
10
Set the NMC to the selected network. For example:
CB5000> set module 4.2 network ethernet_2
You can use the SHOW INTERFACE command to
display information about NMCs, including the
slot.subslot location.
11
Set the default gateway for the selected network to be
the active default gateway for the A/DMM. For
example:
CB5000> set ip active_default_gateway
155.104.10.7
12
Save the default gateway using either the
command or the

14
If you plan to use an SNMP manager to manage the
CoreBuilder 5000 hub, use the SET COMMUNITY
command to create an entry for the manager in the
A/DMM community table.
The following example creates a community named
mgt
. This community provides all access privileges for
an SNMP manager with IP address 155.104.10.9:
