To simplify remote-device management, consider using an IP-address pool to dynamically assign IP addresses
to remote devices as they connect to the Remote Access Concentrator. In order to use an IP address pool,
you must first determine whether or not the Concentrator needs to initiate calls.
• If the Concentrator does not need to initiate calls, establish an IP-address pool rather than assign
permanent IP addresses to all remote devices. Assign as many IP addresses as the number of available ISDN
connections. When a remote device calls in, it will be assigned one of the IP addresses available in the pool.
• If the Concentrator does need to initiate calls, you cannot use an IP pool. You’ll need to
provide permanent IP addresses for all remote devices instead. Skip ahead to
Section 5.2.2
.
To establish a pool in CSM, take these steps:
1. From the CSM Connection Manager, select Configure on the menu bar.
2. Select IP Information.
3. Enter a unique user-defined IP Pool Name.
4. Enter a Start IP Address. The Start IP Address field designates the beginning of a range of IP addresses
used by this “Access Server” (the Concentrator). The Concentrator, in turn, will assign IP addresses from
this range to any remote device not already having an IP address configured. Specify the address in dotted
decimal notation: “XXX.XXX.XXX.XXX”.
5. Enter an End IP Address. The End IP Address field designates the end of a range of IP addresses used by
the Concentrator. Specify the address in dotted decimal notation: “XXX.XXX.XXX.XXX”. The addresses
should be limited to the same subnet, and the number of addresses should not exceed the number of
available ISDN connections.
6. Click “Create New Pool”.
7. Click “Close”.
