The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product. Learn more about how Cisco is using Inclusive Language.
Note For a list of system requirements and package dependencies, see the System Requirements document posted on the Cisco download site for this release.
There is one exception to this automatic package installation. For RHEL operating systems, you must manually install an RHEL package repository (createrepo) using the Red Hat installation DVD.
For assistance with downloading packages for offline installations, contact your support representative.
– Messages might expire prematurely, which manifests as an unresponsive WAE northbound interface. Depending on where the JMS messages expire, you may or may not see indications of this in the logs.
– Certain collection tools, such as sam_getplan
and flow_get
, might produce inaccurate traffic tables.
– Collection tools will produce an inaccurate NetIntHistory table.
– All lines in the collection logs will have incorrect timestamps.
/etc/host
requirements—Various web services require the server's hostname to be present in the /etc/host
file. This is standard configuration practice, but some Linux systems do not have it. Both the unqualified and fully-qualified hostnames must be present. Make sure that the following line is present in /etc/host
.Security—The server’s SSL certificate for a domain is customer specific. The web server installation is tied to a preferred Certification Authority (CA) provider, which in turn issues valid certificates to web clients. To prevent users from seeing messages for untrusted certificates, configure the certificate to be signed by one of the client's trusted CAs. The fully-qualified domain name (FQDN) of the WAE server should match the FQDN of the certificate issued by the CA.
BIOS setting (if applicable)—To improve collection performance, change or disable the power management setting to permit maximum CPU performance.
These pre-installation steps are valid for both online and offline installations.
Step 1 Download the WAE software package, which contains both MATE and WAE software. In a web browser, go to the Cisco download site, and use the Search feature to find the applicable product.
Step 2 Log in to the server as root or a user with administrative capabilities.
Step 3 Create an installation directory that has root privileges. The best practice is to use the default installation directory, which is /opt/cariden.
If using a different installation directory, create it instead of /opt/cariden.
mkdir -p /<custom_installation_directory>
Step 4 Ensure there are no local firewalls blocking the services. This step is beyond the scope of these instructions, though following is an example. For a list of available ports, see the System Requirements document on the Cisco download site for this release.
Example: This shows how to disable the iptables firewall as root.
Step 5 Ensure there are no services are running. For 6.1 services, refer to the Services chapter. For pre-6.1 releases, refer to the following.
