Chapter 3 Connecting on a LAN
Using DHCP

dhcpcParamsShow(pDhcpcBootCookie)—Displays the configuration data
assigned to the JACE by the DHCP server.
Example 3-3 The dhcpcServerShow(pDhcpcBootCookie) command.
All highlighted items are assigned to the JACE by the DHCP server. Highlighted
items are discussed below:
• DNS domain name—the DNS domain for this host. This is also listed in the
DNS Domain field in the Admin Tool.
• Client lease duration—the duration of the DHCP lease, in seconds. To
convert the number to days, divide the number by 60, then by 60, then by 24.
• Client renewal (T1) time value—the amount of time left before the JACE
attempts to renew the lease. The time is listed in seconds. If the lease is not
renewable at this time, then the JACE will reset this timer and continue
attempting renewal until the lease expires (see next parameter).
