The Basic page contains the basic features of CBW560 including Setup,
DHCP and Backup
5.1.2 DHCP
The DHCP page allows you to activate/deactivate the DHCP server function
of the CBW560, and, if the DHCP server is activated, to see DHCP leases it
has provided.
With this function activated, your cable service provider’s DHCP server
provides one IP address for the CBW560, and the CBW560’s DHCP server
provides IP addresses, starting at the address you set in
Starting Local
Address
field, to your PCs. A DHCP server leases an IP address with an
expiration time.
To set the maximum number of PCs to which the CBW560 will issue IP
addresses, enter it in the
Number of CPEs
box and then click
Apply
. (CPE is
another term sometimes used for PC.)
The table on the bottom of this page shows the information of DHCP clients
including the IP and MAC addresses of each PC. Since MAC addresses are
unique and permanently fixed into hardware, you can identify any PC listed by
its MAC address. The CBW560 provides leases for 3600 seconds (default),
and has an automatic renewal mechanism that will keep extending a lease as
long as the associated PC remains active.
You can cancel an IP address lease by selecting it in the DHCP Client Lease
Info list and then clicking the
Force Available
button. If you do this, you may
have to perform a DHCP Renew on that PC, so it can obtain a new lease.
