Situation: When configuring a new Cisco 9200 Switch, there are options to select Uplink and Access. The client would like to know which one he should selelct.

A1: Uplink is usually referred to as a trunk port. This sort of link is used for connecting another Ethernet switch. Technically, this port is preferred to be equipped with higher bandwidth than the access ports on the same (1G port on a 100mbps switch). This consideration is to avoid bottlenecks. The trunk port carries – tagged (vlan tags) or untagged (native or without any tags) or both sort of frames.

A2: Uplink is usually a connection from one network device to another.  It may be a switch to a router, or a router to a router, or a switch to a switch.  Uplink means usually going to the services that your users need access to, e.g. access switches uplinks are distribution switches and the core devices are the uplinks of the distribution.  Different distribution for different functions like a server farm, internet edge, wan edge.

A3: Usually an uplink port connects to another switch, while an access port connects to a host.

In some switches, such as some of the Nexus 9000 range, there are 4-6 40G ports, and 48 10G ports. In this case, the 40G ports are designated as uplink ports, and the rest are edge ports.

A4: There is absolutely no technical difference between an access and uplink port. These definitions are conventional. They signify the functional characteristic of the port, not technical. You can configure physical ports as either access or uplink. Some switches have a small number of higher-bandwidth ports that are usually used as uplink ports. For example, a 100Meg switch might have 2-4 1Gig ports, that are normally used for uplink function. But you can as well configure them as access ports. The higher bandwidth ports are used as uplink ones because they have to carry aggregated traffic from access ports and hence will likely to require more bandwidth. But again, they are technically no different from any other port on the switch.

Situation: When the client downloads Excel 2019 from Microsoft License Center, it downloads Office Deployment Tool (ODT) instead of the Excel setup exe. It says Microsoft recommends using ODT to install Excel 2019. here post shows how to Deploy Excel 2019 using ODT

Step 1: Download the Office Deployment Tool from the Microsoft Download Center

The Office Deployment Tool is a free download from the Microsoft Download Center.

After you download the Office Deployment Tool, double-click on the officedeploymenttool executable (.exe) file to extract the ODT files. Now, you should have several files: setup.exe and some sample configuration.xml files. For an Office 2019-specific sample, see Sample configuration.xml file to use with the Office Deployment Tool.

The setup.exe file is the ODT and is a command-line tool that supports downloading and installing Office 2019. The configuration.xml files are sample files to get you started. You use the configuration.xml file to provide settings for the ODT to use when downloading or installing Office 2019. The configuration.xml is a simple xml file that can be created and edited in any text editor, such as Notepad. You can name the file anything that you want, as long as it retains the xml file extension.

Step 2: Create or Edit the configuration.xml

You can create multiple configuration.xml files to be used with the ODT. For example, you would create a configuration.xml file to download and install the 64-bit version of Office Professional Plus 2019 in English and a different configuration.xml file to install the 32-bit version of Visio Professional 2019 in French. When you run the ODT from an elevated command prompt, you specify which configuration.xml file to use.

Sample configuration.xml file to use with the Office Deployment Tool

This is edited xml file to Excel 2019 Volume license.

STEP 3: DOWNLOAD AND INSTALL LEXCEL 2019

To download the Office 2019 installation files, run this command:

setup /download configuration.xml

To install it, run this command:

setup /configure configuration.xml

After installing a new Cisco 9200 switch, you may use Cisco DNA Center Cloud Onboarding Day 0 Wizard or Classic Day 0 Wizard to configure it. The Web User Interface (Web UI) is an embedded GUI-based device-management tool to simplify device deployment and manageability, and to enhance the user experience. We can use WebUI to build configurations, monitor, and troubleshoot the device without having CLI expertise. This article is showing you how to configure Cisco 9200 Switch using Classic Day 0 Wizard.

Step 1: Connecting to the Switch by Setting up the DHCP Client Identifier on the client to get the IP address from the switch

1. find your computer IP address by running ipconfig /all command.

2. Run Registry editor by typing regedit in the Windows search box and press enter.

3. If prompted by User Account Control, click Yes to open the Registry Editor.

4. Navigate to Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\ 

5. Locate the Ethernet Interface Global Unique Identifier (GUID). in our example Ethernet 2 and IP 10.144.0.25. Note: don’t use 10.1.10.173 because it is WiFi IP address.

6. Add a new REG_BINARY by right clicking on new > Binary Value.

7. Type DhcpClientIdentifier with Data 77 65 62 75 69 for webui.

8. it shows like that.

Step 2: Connect to Switch using WebUI

1. Make sure that no devices are connected to the switch.
2. Connect one end of an ethernet cable to one of the downlink (non-management) ports on the active supervisor and the
   other end of the ethernet cable to the host (PC/MAC).
3. Set up your PC/MAC as a DHCP client, to obtain the IP address of the switch automatically. You should get an IP address
   within the 192.168.1.x/24 range.
4. Launch a web browser on the PC and enter the device IP address (https://192.168.1.1) in the address bar.
5. Enter the Day 0 username webui and password cisco.

Backup Repository Server

Specification

Requirement

Hardware

CPU: x86 processor (x86-64 recommended).Memory: 4 GB RAM plus 2 GB RAM (32-bit OS) or 4 GB RAM (64-bit OS) for each concurrent job. Using more memory improves data processing performance for long chains of large backup files on backup repositories running 64-bit OS.Disk space: 200 MB for Veeam Backup & Replication components and sufficient disk space to store backup files and replicas (high-RPM drives and RAID10 configuration recommended).Network: 1 Gbps LAN for onsite backup and replication and 1 Mbps WAN for offsite backup and replication recommended. High latency and reasonably unstable WAN links are supported.

Based on our experience, for Windows server with 5 or more VMs, it is better to have at least 16GB RAM for the physical server self.

Some people also ask how to calculate virtual memory needed to compact backup. “

From this perspective I think If repository has 16GB RAM, virtual memory is increased during the compact job up to 48GB. If compact job is still not finished, OS is unable to increase the virtual memory and task is failed with the error “Unable to allocate memory for storage metadata bank”.

The obvious workaround for this problem – assigning more RAM or manual configure virtual memory limits. But the question I have – how large should be virtual memory to compact 20TB of data? I wound experiment with size because such job takes days. So if someone has experience or know how I can calculate virtual memory needed for such task, would be great.”

A1: I don’t have a specific formula, but I had the same errors when doing a compact with multiple jobs with 2-3 TB files each. I went from 16 GB to 32 GB and all of those went away. Now that I’m doing Copy Jobs as well, I just increased to 48 GB and it still got into the 90% used range. More is better.

A2: Such memory consumption doesn’t look expected, indeed. The process performing compact requires ~150 bytes per block, which even with the smallest block possible (256 KB) gives 12 GB of RAM for 20 TB backup file. What block size is used for this job? I also recommend opening a case with our technical support for a closer investigation.
