5.4.5.4.14Overriding a Miscellaneous Network Configuration
Overriding the Network Configuration
An access point profile can be configured to include a hostname in a DHCP lease for a requesting device and its profile. This
helps an administrator track the leased DHCP IP address by hostname for a device profile. When numerous DHCP leases are
assigned, an administrator can better track the leases when hostnames are used instead of devices.
To include a hostnames in DHCP request:
1. Select Devices from the Configuration tab.
2. Select Device Overrides from the Device menu to expand it into sub menu options.
3. Select a target device from the device browser in the lower, left-hand side of the UI.
4. Select Network to expand its sub menu options.
5. Select Miscellaneous.

6. Select the Include Hostname in DHCP Request option to include a hostname in a DHCP lease for a requesting device.
This feature is enabled by default.
7. Select the DHCP Persistent Lease option to retain the last DHCP lease used across a reboot if the access point’s
designated DHCP server is unavailable. This feature is enabled by default.
8. Select the OK button to save the changes and overrides. Select Reset to revert to the last saved configuration.
5.4.5.4.15Overriding Alias Configuration
Overriding the Network Configuration
With large deployments, the configuration of remote sites utilizes a set of shared attributes, of which a small set of attributes
are unique for each location. For such deployments, maintaining separate configuration (WLANs, profiles, policies and ACLs)
for each remote site is complex. Migrating any global change to a particular configuration item to all the remote sites is a
complex and time consuming operation.
Also, this practice does not scale gracefully for quick growing deployments.
An alias enables an administrator to define a configuration item, such as a hostname, as an alias once and use the defined
alias across different configuration items such as multiple ACLs.
Once a configuration item, such as an ACL, is utilized across remote locations, the alias used in the configuration item (ACL) is
modified to meet local deployment requirement. Any other ACL or other configuration items using the modified alias also get
modified, simplifying maintenance at the remote deployment.
NOTE: A blue override icon (to the left of a parameter) defines the parameter as having
an override applied. To remove an override, go to the Basic Configuration screen’s Device
Overrides field and select Clear Overrides. This will remove all overrides from the
device.
