Link

The Inventory Link Screen displays all links that known to OmniVista Cirrus. It is also used to manually create, clone, edit, and delete manual links. Unlike automatically-discovered Links, which disappear from the Topology map view when they become unreachable, manual links will be persistent and display in RED when the link goes down. This enables users to manually configure critical links, such as the network core links (which are seldom changed), providing better monitoring capability for critical links.

Creating a Link

Click on the Create icon and complete the fields as described below. When you are finished, click on the Create button.

• IP Address 1 - The IP address of one device in the link. Select an option from the drop-down menu (Use Switch Picker/Use Topology), click on the Select Device button and select a device.
• Slot/Port 1 - Select a slot/port for IP address 1 from the drop-down menu.
• LAG 1 - If this is a link aggregation link, set the LAG 1 field to the Link Aggregation Number assigned by the device above when the link aggregation group was created.
• IP Address 2 - The IP address of the second device in the link. Select an option from the drop-down menu (Use Switch Picker/Use Topology), click on the Select Device button and select a device.
• Slot/Port 2 - Select a slot/port for IP address 2 from the drop-down menu.
• LAG 2 - If this is a link aggregation link, set the LAG 2 field to the Link Aggregation Number assigned by the device above when the link aggregation group was created.
• Media Type - Select the media type for the link from the drop-down menu.
• Status - Select the administrative status for the link from the drop-down menu (Up/Down). Note that you can edit the link later if you want to change the status.

Cloning a Link

You can clone an LLDP link to create a manual link. If an LLDP link goes down, a "Link Down" Trap is sent, but the link will disappear from the Topology map on the next poll because it no longer exists. However, if you clone an LLDP link to create a manual link, the manual link will continue to display (in Red) on the Topology map.

Click on the Clone LLDP To Manual button to bring up the Clone LLDP To Manual Screen. Click on the Links ADD button and select the link(s) you want to clone. (You can click on the EDIT button to add/remove links from the selection.) When you are finished, click on the Create button. The new manual link(s) will appear in the Existing Links Table.

You can also clone and edit an LLDP link to quickly create a new manual link on different ports on a device. Clone and create a manual link as described above. Select the new manual link in the Existing Links Table, click on the Edit icon, and edit the link.

Editing a Link

You can edit manual links, select a manual link in the Existing Links Table and click on the Edit icon. Edit the available fields as described above and click on the Apply button. Note that only manual links can be edited. Any other links (e.g., LLDP, SPB) cannot be modified.

Deleting a Link

Select a link in the Existing Links Table and click on the Delete icon. Click OK at the Confirmation Prompt. Note that only manual links can be deleted. Any other links (e.g., LLDP, SPB) cannot be deleted.
