5.1.2 DHCP
The DHCP page allows you to activate/deactivate the DHCP server function
of the CBV704EW, 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 CBV704EW, and the CBV704EW’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 CBV704EW 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 CBV704EW 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.
Advanced
The Advanced page allows you to enable/disable some advanced features of
the CBV704EW.
