Management Interface is used to communicate with Traffic Analyzer software (HTTP,
SNMP). Which one you use, determines how to configure NAM IP.
Management Interface is used to communicate with Traffic Analyzer software (HTTP,
SNMP). Which one you use, determines how to configure NAM IP.
Internal NM-NAM Interface:
• Use router CLI to assign an IP
address from a routable subnet to the
Analysis-Module interface
• For the NAM, use NAM CLI to assign
an IP address from the same subnet
that is assigned to the Analysis-
Module interface.
External NM-NAM interface:
• Use router CLI to assign an IP address to
the Analysis-Module interface. The subnet
does not need to be routable.
• For the NAM, use NAM CLI to assign an
IP address from the subnet that is
connected to the external NAM interface.
NM-NAM Management Interface
To actually configure IP on the NM-NAM itself, the administrator must first decide which of the two NAM
interfaces are to be used as the management interface or the interface end-user will use to communicate
with the NM-NAM. (management traffic such as IP, HTTP, SNMP, Telnet, and SSH.) You cannot send
management traffic through both NAM interfaces at the same time.
Note: Using the Internal NM-NAM interface as the management interface requires router resource. Using the
External NM-NAM interface as the management interface requires the interface to be connected to a LAN.
How you assign IP addresses on the NAM network interfaces depends on which NAM interface, internal or
external, you use for management traffic.
If you select the internal NAM interface to handle management traffic:
• For the Analysis-Module interface (in Cisco IOS CLI), assign an IP address from a routable subnet. To
conserve IP address space, you can configure the Analysis-Module as an IP unnumbered interface
and borrow the IP address of another router interface, such as a Fast Ethernet or loopback interface.
The borrowed IP address must come from a routable subnet.
• For the NAM system (in NAM CLI), assign an IP address from the same subnet that is assigned to the
Analysis-Module interface.
If you select the external NAM interface to handle management traffic:
• For the Analysis-Module interface (in Cisco IOS CLI), we recommend that you use the IP unnumbered
interface configuration to borrow the IP address of another router interface. The subnet does not need
to be routable.
• For the NAM system (in NAM CLI), assign an IP address from the subnet that is connected to the
external NAM interface.
