Description
This command configures an alias for an IPv4 network host, subnetwork, or range of addresses.
Syntax
Usage Guidelines
Aliases can simplify configuration of session ACLs, as you can use an alias when specifying the traffic source and/
or destination. Once you configure an alias, you can use it in multiple session ACLs.
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
Parameter Description Default
host Configures a single IPv4 host and its position in the list.
—
invert Specifies that the inverse of the network addresses configured are used. For example, if a
network of 172.16.0.0 255.255.0.0 is configured, this parameter specifies that the alias matches
everything except this subnetwork.
—
<name> Name for this host or domain.
—
network An IPv4 subnetwork consisting of an IP address and netmask.
—
no Negates any configured parameter.
—
range A range of IPv4 addresses consisting of sequential addresses between a lower and an upper
value. The maximum number of addresses in the range is 16. If larger ranges are needed,
convert the range into a subnetwork and use the network parameter.
