Network views: campus map and switch faceplate

The views combine files that your team maintains with records from source reads. The table below identifies the inputs.

Where each element comes from

Each displayed element comes from a maintained file, a source read or an inference.

Campus map

The campus map places buildings and closets from the site file your team maintains. It draws the switch-to-switch links between buildings that the switches report, and labels them as observed links, not cable routes.

The header counts the buildings and the links between buildings.

• Placement drafts. When Devexana places a building from a switch name, the placement is a draft. Confirm or move each draft in the sites editor before you rely on it.
• What "fiber" means. The word "fiber" in the campus view means inter-building links, plus optics facts where a read returns them. It is not a record of fiber strands.
• Connections list. The list beside the map names each pair of joined buildings, with its strand count and speed. Each switch-to-switch link that the switches report counts as one "strand". This is a count of logical links, not a count of fiber strands. Links inside one building have their own row.
• Link details. A link card shows the speed, the VLANs and the optics facts that the reads returned. If a source read reports an optical alarm, the map marks the link and the Connections list shows optic alarm.
• Freshness. If a neighbour table is older than 24 hours, the view marks the link as stale.

Only an administrator can edit sites. Each edit writes a record to the audit log. To confirm a draft placement, do these steps:

1. Open Networking › Devices › Campus.
2. Find the building that shows as a draft.
3. Compare its position with your own site records.
4. If the position matches your site records, confirm the placement.
5. If the position is incorrect, move the building to the correct position.

Switch faceplate

The switch faceplate combines the port state that the switch reports, your port map, the devices seen on each port, and VLANs.

• Reachability. The view states whether the switch is reachable, stale or unreachable now. This is the current state, not a history.
• No read method. If no read method reaches a switch, the faceplate still opens. It marks the switch as not reachable and shows the ports from your port map. See A switch is listed but not read.
• Backup-only switches. A switch known only from a configuration backup shows no port status.
• Port trace. The port trace follows neighbour links from a port to the next switch.

To trace a port, do these steps:

1. Select a port.
2. Start the port trace to follow neighbour links to the next switch.

What depends on the read method

What a view can show depends on how Devexana reads each switch. Switches over SSH and SNMP explains each read method.
