DHCP server for an IP address and provides the DHCP server with its sysid. The DHCP server includes this sysid with the IP

address that it assigns to the appliance in the server's dhcpd.leases ﬁle. To ﬁnd the IP address currently assigned to your

NetScaler Gateway, look in the dhcpd.leases ﬁle for the last entry with the sysid of your appliance in the uid or client-

hostname ﬁeld. Verify that the binding state in this entry is active. If the binding state is not active but free, the IP address

is not yet associated with the appliance.

You can use this address to connect to NetScaler Gateway and remotely conﬁgure the initial settings. For example, you can

change the IP address, subnet mask, and gateway settings that were fetched from the DHCP server. After completing the

initial conﬁguration, you can manually return the DHCP IP address to the server pool. Alternatively, restarting the appliance

automatically releases the DHCP IP address back to the server pool. A restart also saves the NetScaler Gateway

conﬁguration ﬁle.

Example

The following code example shows an entry in a DHCP server’s dhcpd.leases ﬁle. This entry veriﬁes the binding state of the

appliance with a sysid of 45eae1a8157e89b9314f.

lease 10.102.33.248 {

starts 3 2009/08/19 00:40:37;

ends 3 2009/08/19 06:40:37;

cltt 3 2009/08/19 00:40:37;

binding state active;

next binding state free;

hardware ethernet 00:d0:68:11:f4:d6;

uid "45eae1a8157e89b9314f";

client-hostname "45eae1a8157e89b9314f";

In the preceding example, the binding state is ACTIVE and the IP address assigned to the NetScaler is 10.102.33.248.

The following table describes DHCP-related command-line interface commands that you might want to use when

conﬁguring a new NetScaler Gateway.

Task At the command

prompt , type:

To verify the DHCP fetched details, such as IP address, subnet mask, and gateway on the

appliance.

> sh dhcpParams

To release the DHCP IP address and return it to the IP address pool on the DHCP server

when the appliance conﬁguration is complete.

> release dhcpIP

Using DHCP When a Conﬁguration File Is Present

If you need to move a NetScaler Gateway appliance to a different subnet, such as from a testing environment to a

production environment, you can use DHCP to access a NetScaler Gateway that already has a conﬁguration ﬁle. Before
