The term mnemonic in Iris is a named element. The reason that Iris names elements is so that they can be identified when doing a search.

The name is usually derived from the description line of an interface or just the element name.

Iris uniquely identifies elements by using tags. You can often choose between referencing the tag or the mnemonic when, for example, setting up a report or thresholds.

Tags come in different formats. Here is an example of a service policy tag that we use in Iris:

How to edit the alias to a mnemonic

An alias is a friendly name for a mnemonic. There is no way for you to add a mnemonic in the front-end as this data is populated via SNMP automatically. This is how we change an alias of a mnemonic.

On the Mnemonics page, double click on the mnemonic that you would like to edit or click the edit icon in the actions column.

Mnemonic: The mnemonic will be automatically populated from the router during discovery.

Base Tag Name: This will automatically be populated from the router during discovery.

Alias is a friendly name. Iris prefers alias, then base tag and finally uses the mnemonic to describe an element.

Circuit Identifier: This is a free text field for additional information.

Service Tag: This is a way of grouping the mnemonic based on service. e.g. web service, email service, etc.

Monitoring: The address will display the IP block that Iris has discovered.

Monitors will show the IP address that Iris will ping.

VRF is the IP address inside the VRF (if you have a vPoller).

If the lock is open, the IP is no longer automatically set.

Views: You have to manually assign the mnemonic to a view. A mnemonic may be assigned to multiple views.

Notes: The notes that you include will form part of the email notification.

How to move a mnemonic into a view (site)

To add a mnemonic to a site, you should search for the site in the View search box and then click add. It is possible to have mnemonics in many views, however this is strongly discouraged as effectively means there are two or more “points of view” that need to be maintained for the same mnemonic and it puts additional load on the system. There are usually much better ways to achieve the same thing which are less confusing. Look at managing views for more information.

Note that in order for mnemonics to be moved into a view, the device must be multi-tenanted. In other words, a PE or similar kind of device. If the device is not multi-tenanted (as is the case with a CE device), then you’ll see the following message.
