NetApp provides tree different types of virtual interfaces (VIF): - Single-mode VIF - Static Multi-mode VIF - Dynamic Multi-mode VIF   - Single-mode VIF A single-mode VIF contains a single active link and a number of links in passive mode. All links in the single-mode VIF share a single MAC address. Only one link is active and sending data therefore there is never a duplicate MAC address on the network. A single-mode VIF is configured with two links connected to redundant switches. Only link e0 is active, while the e1 is in standby mode. If e0 fails (signalled by the link status of the interface going down), the remaining link will take over. In the case of multiple standby interfaces, the storage device will randomly pick one to bring up as the active link. This is commonly known as active passive mode. (Source NetApp Technical report TR3802)   - Static Multi-mode VIF A static multi-mode VIF contains two or more interfaces in which all links are active. This follows the 802.3ad (static) IEEE standard and requires support and configuration on the switch. However, neither LACP nor PAgP are support in this configuration, so no negotiation or auto-detection of the aggregated ports occurs. The switch must be configured in “on” or “static” mode, which forces the interfaces to form a channel. Static multi-mode VIFs are able to continue operating even if all but one link has been lost. This allows for higher throughput than a single mode VIF, and still provides redundancy. (Source NetApp Technical report TR3802)   - Dynamic Multi-mode VIF Dynamic multi-mode VIFs are based on Link Aggregation Control Protocol (LACP) as described by the IEEE 802.ad (dynamic) standard. They are similar to static multi-mode VIFs in that they contain two or more active interfaces, share a single MAC address, and require configuration on both ends of the connection. In a dynamic multi-mode VIF, however, additional negotiation parameters are passed between the devices using an LACP Protocol Data Unit (PDU). This allows for the two connected devices to dynamically add and remove links from the channel for reasons other than physical link failure. This is an important distinction, because dynamic multi-mode VIFs can not only detect and compensate for a loss of link, but also a loss of data flow. This leads to higher availability and can help prevent the packet black hole problem discussed in the single-mode VIF section.

Possible causes and solution(s)   Project set-up: VG4 Autodome MPEG cameras with FW 4.10 VRM 3.83 DSA E2800 storage Note: these MPEG4 cameras are EoL and EoS for a long time now and the Central Technical Support team assistance is done on best effort.   Causes VG4 AutoDome camera: recording doesn’t work & Bosch logo is displayed in cameo Adding the VG4 Autodome MPEG cameras directly to the VRM is not possible because of the firmware version (as per release letter, minimum firmware is 4.15) “VRM 3.82 itself is backward compatible with firmware versions 4.15 or higher.”   Solution We suggested to add the cameras through VSG by using Configuration Manager But make sure there is no recording enabled on the camera itself:   But only a recording running on the VSG instances:   Now the camera will be streaming to the VSG and the VSG will take care that that stream will be recorded via the VRM. If cameras still don't have image in playback mode but the recordings are taking place, or when you are changing from live view to playback: the recording on the camera stops and the “video lost” message occurs in OP client, then continue with the following steps: try to factory reset the complete camera first (by press and hold the button on the camera) reinstall VSG/VRM on the machine (use the latest build available on the DLS) Then try to add camera back to the VSG.   By changing Set Recording Quality – Stream Quality Settings to 2/3 D1, the VG4 IP camera will be in recording mode. It might happen that by changing to 2 CIF or 4 CIF/D1, the recording will not work anymore, and it will show only the Bosch logo in the cameo. This happens because the camera is not sending I-frames to the VSG. You have to set the camera manually to send I-frames. However, if you want to use the maximum resolution possible with the VG4 camera and fix the Bosch logo described above, please follow the steps below. Note: If you want to do these changes via Configuration Manager, it will not work well for this old firmware. Therefore, for this old firmware you should use the webpage of the camera.   Open the settings in the webpage Go to 'Advanced mode' Go to 'Encoder' Go to 'Encoder profile' Choose in the 'Profile configuration' the profile of choice (standard is the 4CIF profile 3) Click on 'Details' And change the 'I-frame distance' to 1 Click on 'set' in that pane Now you will see that the message in the CM will go from 'No I-frames' to 'Streaming'   ...

Question   How can I remotely configure VCA in Alarm Management?   Answer   Remote VCA configuration through the camera's device page (website) now can be performed with Bosch Configuration Manager version 7.60 and later.   Please perform the following steps: Download Bosch Configuration Manager v 7.60 or later from Bosch downloadstore and install on your computer. Open Device Page in Alarm Management Configuration Select Alarm > VCA > click button "Configure in Bosch Configuration Manager" Configuration Manager opens displaying the VCA Configuration   After Configuration has been completed, click the Save button in Configuration Manager.   Known Limitations: Remote VCA configuration is supported for all Bosch IP cameras with firmware version 7.80 and later which are commissioned to Alarm Management by its MAC address. For remote VCA configuration of Remote Portal cameras, please start the Bosch Configuration Manager on your computer and connect to your Remote Portal account to configure your cameras. For cameras with firmware versions earlier than 7.80, for remote VCA configuration please continue using the Internet Explorer 11 with Video SDK or MPEG ActiveX v6.36.0233 installed, and Active X components being allowed in the browser, or use the Bosch Configuration Manager in the local camera network (= local VCA configuration).   ...
