7.5 Alias

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
across all devices, profiles and RF Domains in the system.
• Profiles aliases are defined from
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
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.
• Device aliases are defined from
are utilized by a single device only. Device alias values override alias values defined in a global alias, profiles alias or RF
Domain alias configuration.
Using an alias, configuration changes made at a remote location override any updates at the management center. For example,
if an Network Alias defines a network range as 192.168.10.0/24 for the entire network, and at a remote deployment location,
the local network range is 172.16.10.0/24, the network alias can be overridden at the deployment location to suit the local
requirement. For the remote deployment location, the network alias works with the 172.16.10.0/24 network. Existing ACLs
using this network alias need not be modified and will work with the local network for the deployment location. This simplifies
ACL definition and management while taking care of specific local deployment requirements.
Alias can be classified as:

A basic alias is a set of configurations that consist of VLAN, host, network and address range alias configurations. VLAN
configuration is a configuration for optimal VLAN re-use and management for local and remote deployments. A host alias
configuration is for a particular host device's IP address. A network alias configuration is utilized for an IP address on a
particular network. An address range alias is a configuration for a range of IP addresses.
A basic alias configuration can contain multiple instances for each of the five (5) alias types.
