Network Basic Alias
A basic alias is a set of
configurations consisting of VLAN, Host, Network
and Address Range alias configurations. A VLAN
alias 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.
To set a network basic alias configuration:
-
Select .
The Basic Alias screen
displays.
-
Select + Add Row to define VLAN
Alias settings:
-
Use the VLAN Alias field to create unique aliases for
VLANs that can be used at different deployments. For example, if a named VLAN is
defined as 10 for the central network, and the VLAN is set at 26 at a remote
location, the VLAN can be overridden at the deployment location with an alias.
At the remote deployment location, the network is functional with a VLAN ID of
26 but utilizes the name defined at the centrally managed network. A new VLAN
need not be created specifically for the remote deployment.
Name |
If adding a new VLAN Alias, provide it a distinguishing
name up to 32 characters. The alias name always starts with
a dollar sign ($). |
VLAN |
Use the spinner control to set a numeric VLAN from 1 -
4094. |
A VLAN alias is used to replace VLANs in the following locations:
- Bridge VLAN
- IP Firewall Rules
- L2TPv3
- Switchport
- Wireless LANs
-
Select + Add Row to define Address Range
Alias settings:
-
Use the Address Range Alias field to create aliases for
IP address ranges that can be utilized at different deployments. For example, if
an ACL defines a pool of network addresses as 192.168.10.10 through
192.168.10.100 for an entire network, and a remote location‘s network range is
172.16.13.20 through 172.16.13.110, the remote location‘s ACL can be overridden
using an alias. At the remote location, the ACL works with the 172.16.13.20-110
address range. A new ACL need not be created specifically for the remote
deployment location.
Name |
If adding a new Address Alias, provide it a
distinguishing name up to 32 characters. The alias name
always starts with a dollar sign ($). |
Start IP |
Set a starting IP address used with a range of addresses
utilized with the address range alias. |
End IP |
Set a ending IP address used with a range of addresses
utilized with the address range alias. |
An address range alias can be used to replace an IP address range in IP
firewall rules.
-
Select + Add Row to define Host
Alias settings:
Use the
Host Alias field to create aliases for hosts
that can be utilized at different deployments. For example, if a central network
DNS server is set a static IP address, and a remote location‘s local DNS server
is defined, this host can be overridden at the remote location. At the remote
location, the network is functional with a local DNS server, but uses the name
set at the central network. A new host need not be created at the remote
location. This simplifies creating and managing hosts and allows an
administrator to better manage specific local requirements.
Name |
If adding a new Host Alias, provide it a distinguishing
name up to 32 characters. The alias name always starts with
a dollar sign ($). |
Host |
Set the IP address of the host machine. |
A host alias can be used to replace hostnames in the following
locations:
-
Select + Add Row to define Network
Alias settings:
Use the
Network Alias field to create aliases for IP
networks that can be utilized at different deployments. For example, if a
central network ACL defines a network as 192.168.10.0/24, and a remote
location‘s network range is 172.16.10.0/24, the ACL can be overridden at the
remote location to suit their local (but remote) requirement. At the remote
location, the ACL functions with the 172.16.10.0/24 network. A new ACL need not
be created specifically for the remote deployment. This simplifies ACL
definition and allows an administrator to better manage specific local
requirements.
Name |
If adding a new Network Alias, provide it a
distinguishing name up to 32 characters. The alias name
always starts with a dollar sign ($). |
Network |
Provide a network address in the form of
host/mask. |
A network alias can be used to replace network declarations in the
following locations:
-
Select + Add Row to define String
Alias settings:
Use the
String Alias field to create aliases for
strings that can be utilized at different deployments. For example, if the main
domain at a remote location is called loc1.domain.com and at another deployment
location it is called loc2.domain.com, the alias can be overridden at the remote
location to suit the local (but remote) requirement. At one remote location, the
alias functions with the loc1.domain.com domain and at the other with the
loc2.domain.com domain.
Name |
If adding a new String Alias, provide it a distinguishing
name up to 32 characters. The alias name always starts with
a dollar sign ($). |
Value |
Provide a string value to use in the alias. |
A string alias can be used to replace domain name stings in DHCP.

rules. Select Reset to revert the screen back to its last
saved configuration.
