Usage
Aliases can simplify configuration of session ACLs, as you can use an alias when specifying the traffic source
and/or destination it in multiple session ACLs. Once you configure an alias, you can use it to manage network
and host destinations from a central configuration point, because all policies that reference the alias will be
updated automatically when you change the alias.
When using the invert option, use caution when defining multiple aliases, as entries are processed one at a
time. As an example, consider a netdestination configured with the following two network hosts:
netdestination dest1 invert
network 1.0.0.0 255.0.0.0
network 2.0.0.0 255.0.0.0
A frame from http://1.0.0.1 would match the first alias entry, (which allows everything except for 1.0.0.0/8) so
the frame would be rejected. However, it would then be compared against the second alias, which allows
everything except for 2.0.0.0/8, and the frame would be permitted.
Example
The following command configures an alias for an internal network:
(host) (config) #netdestination Internal
network 10.1.0.0 255.255.0.0
Example
The following command overrides the local network destination:
(host) (config) #netdestination store
(config-dest) #host vlan 55 offset 36
