IMC also lets you locate IP or MAC addresses in the network infrastructure. This feature is useful for
pinpointing to which access device a particular user is located when some information about the user is
known. This is useful both for troubleshooting network issues and tracking down security problems in the
network infrastructure.
Allocating IP addresses
IMC lets you manage the allocation of IP addresses for reporting and alarming purposes. You can add
an IP segment and perform an auto scan for or assign IP addresses to the IP segment. You can create
child IP segments under an IP segment, and can build an IP segment structure of at most five levels. You
can perform a global auto scan, and then IMC automatically adds the IP addresses to existing IP
segments. If the IP addresses do not belong to any existing IP segment, IMC adds them to the system
default IP segment.
In addition, you can batch import IP addresses to IMC from a file, such as the IP address file of a DHCP
server. The following section provides you with information on the IMC IP address allocation features.
Viewing the IP segment list
IMC provides you with the ability to view existing IP address allocations.
To view IMC existing IP address allocations:
1. Navigate to Resource > IP Address Allocation.
2. Click the Resource tab from the tabular navigation system on the top.
3. Click Terminal Access on the navigation tree on the left.
4. Click IP Address Allocation under Terminal Access from the navigation tree on the left.
The IP Segment List is displayed in the IP Address Allocation page.
