Update Fingerprints
ExtremeAnalytics uses fingerprints to identify to which application a network
traffic flow belongs. A fingerprint is a description of a pattern of network traffic
which can be used to identify an application. Extreme Management Center
provides thousands of system fingerprints with the ExtremeAnalytics feature. In
addition, you can modify these fingerprints and create new custom fingerprints.
In order to add and modify fingerprints, you must be a member of an
authorization group assigned the Extreme Management Center
ExtremeAnalytics Read/Write Access capability.
Updating Fingerprints
New and updated fingerprints are provided via a fingerprint update website.
Perform a one-time manual update of the fingerprint database or configure a
scheduled update to be performed automatically from the Configuration tab.
Custom fingerprints are not overwritten when an update is performed.
When a fingerprint update is performed, the fingerprint update server is
checked for newer fingerprints than what is available on the Extreme
Management Center server. If there are newer fingerprints, they are downloaded,
and the fingerprint definitions are updated with any new fingerprint definition
files. You need to enforce your engines following an update to push the updated
fingerprints to the engines.
Perform a Fingerprint Update
Perform a manual one-time update of the fingerprint database. To access the
update website, you need to create an Extranet account at
ExtremeNetworks.com and define a username and password for the account.
You need the username and password in order to perform updates.
1. Select the Analytics tab in Extreme Management Center and then select the
Configurations view.
