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.
Aliases have scope depending on where the Alias is defined. Alias are defined with the following scopes:
• Global aliases are defined from the Configuration > Network > Alias screen. Global aliases are available for use globally
across all devices, profiles and RF Domains in the system.
• Profiles aliases are defined from Configuration > Devices > System Profile > Network > Alias screen. These aliases
are available for use to a specific group of wireless controllers or access points. Alias values defined in this profile override
alias values defined within global aliases.
• RF Domain aliases are defined from Configuration > Devices > RF Domain > Alias screen. These aliases are available
for use for a site as a RF Domain is site specific. RF Domain alias values override alias values defined in a global alias or a
profile alias configuration.
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.
