Network Management involves issues that are independent of specific hardware or software, including email policies, upgrade planning, backup scheduling and working with managed service providers for Desktop-As-A-Service (DaaS), Software-As-A-Service (SaaS) and the like through the use of tools, coupled with manufacturer standards, best practice guidelines, policies and procedures plus all other relevant documentation. Network management also includes monitoring, alerting and reporting, management reporting, planning for device or service updates, the backup of configurations, the setting of key performance indicators and measures (KPIs/KPMs), associated service level agreements and problem records as part of the IT Service Management (ITSM) framework.

I want to be able to see a dynamic map of my devices. We have a number of sites with allocated subnets and it would be useful to be able to visualise what is connected where. Most of these assets will move from site to site. Is there an agent based tool that would "check in" when its connected to a network?

I have a Windows(ver. 1903) 10 Dell 9020 desktop.  
1. This computer is part of a domain
2. I have mapped several UNC (to the servers) drives from M to P
3. All of the drives function properly with the exception of the M drive
4. After mapping the M drive ( have tried both with an IP Address and a Computer Name) the drive functions properly.  I can view the contents of the drive.
5. HOWEVER, each time the computer is restarted the M drive is disconnected (I cannot see the drive in Windows explorer).  
6. All the other drives continue to function properly.
7. After the computer has restarted I can map the M drive again and it functions properly until restart.

Notes: a. I click to reconnect on restart
b. The M drive is mapped to a folder that goes to an Accounting program (in other words if the M drive is disconnected the Accounting program does not open.
c. Other computers on the network are able to use the M drive successfully.  It is only one computer.
d. I have used the netuse command "net use x: /delete" followed by "net use x: \\server\share" however the drive does not show in Windows Explorer.
e. I have browsed but the local group policy and the startup folder for anything related to override or disconnect the M drive

Please Advice
Thanks in Advance

I have set up tacacs a number of times but one feature i have never found that i have seen implemented (thought i don't know if this was just using TACACS). Was when logging in to a device you had to provide a ticket ref as part of the log in process  and this was then recorded centrally, So you could search logs and see what was done under a specific ticket reference.  

Any thoughts? I would like this to be recorded with in ISE if possible.

Thank you

We have a couple Cisco SX20 video conferencing units.  They had up until this semester been working fine.  This semester we are experiencing high packet loss outbound only (we can see and hear everyone fine but they get jitter and dropped audio).  We have tried a bunch of things to fix the problem, but nothing seems to work.  I am curious what usually causes this level of loss (anywhere from 6 to 20 % packet loss that goes up and down during the course of a call).  

I have updated the firmware to the latest version 9.9.2, added QOS to the uplink port on the Cisco switch stack it connects to, and tired a multitude of things to get this working.  Very frustrating for the distance learning they are trying to do.  Any thoughts or suggestions would be appreciated.

Hello Experts,

I am looking for feedback on this.

I have client that is expanding and the clients signed a contract for unmanaged wavelength from their data center on premise to the new site office ,  do you know what to expect exactly from the ISP.

The internet access will be from the data center.

Thanks,

I have some strangeness happening. Please take a look at the diagram so that you can use as a reference. Maybe once or twice a day the inter goes in and out at building 2 and 3. When it goes out I get some ping request that fail to Edgeswitch3. Edge switch 3 is connected to Edgeswitch2 via ethernet patch cable. I cannot ping edgeswitch 2 at all. Here are my findings and strange things I found. Lets start with Edgeswitch 1

Server resides where Edgeswitch 1 resides

Edgeswitch 1
1) When I log in I connect via https://192.168.1.1
2) When I log in to the legacy interface it says the ip address is 192.168.2.2 (See screenshot)
3) Fiber connects Edgeswitch 1 to Edgeswitch2

Edgeswitch 2
1) Cannot ping this switch, or access the gui as a result. I logged into via serial console (Putty) and confirmed the ip address is 192.168.1.2.
2) I have the running config attached below.
3) Edgeswitch 2 connected to Edgeswitch 3 via ethernet patch cable.
4) This switch has been this way for a few years. It worked so I did not reset it. Someone else configured this switch.

Edgeswitch 3
1) 192.168.1.4 (I can ping it, but when the ping is not 1ms consistently. Sometimes its 64ms, 15ms, all up and down.

I see no errors on the port statistics. on Switch 1 and 3. Im contemplating resetting Edgeswitch 2.

I am looking for a very basic network testing tool/app that will accurately monitor and then send me an email or a text every time my network goes down.  

It's for a home network, often I am not there, so I will be unaware that there has been a brief outage, I have been working with my broadband supplier and also a local IT repair company to get to the bottom of an ongoing intermitting issue over the past 2 months..

I want to run two ongoing tests, one on my WiFi and one on my wired/RJ45 network, both of which originate from the same broadband supply.

I know that three are very elaborate network monitoring tools, but I just need something accurate and basic with an alert feature.

Hi,

I've been given the below from my network team.

192.168.10.0/20 – they've asked me to subnet accordingly and re-address your VLANs with.

Can someone advise what is required

Thanks in advance

Hi,

We have an internet download speed of 10mb/s.

We have 10 Windows 10 PCs running 4K videos on our network.

Would this mean lower capacity or network speeds for our network?

Thanks,

SDN and SD WAN and SD Access and DNA Center

I have read about SDN and SD WAN.  if I understand They both are based on Centralized Control Plane.

So if I have  the Traditional Local Area Network  made up of Access/Distribution/Core   Layers,  and when I want to Implement SDN Technology , at what layer should I integrate SDN.
in other words if there is a hardware on which SDN is installed on, where should that hardware be located ?

SD WAN is WAN Technology , if I want to implement that technology  where should  I put the hardware that holds the SD WAN software.

if you can briefly give the    difference between SDN , SD-Access, SD WAN, DNA Center that might also help clear up the Terminology confusion.

THank you

Cisco RV016 have 2 wan ports. I have on Wan 1 100Mbs and  at Wan 2 50Mbs. My problem is how to prioritize the traffic to wan 1. Today all my traffic are on Wan 2. It only changes if I unplug the cable.

I have a HP 2920-48G-PoE switch and I am trying to change a single port from VLAN24 to VLAN32.

All the switches are controlled by HP Intelligent Management Center running on Windows 20102 R2.

I keep getting a SNMP request timeout error that states possible reasons:

1. The device is not reachable
2. The SNMP read-write community name is incorrect

I have tried to telnet/ssh to the switch itself but, even though both protocols are allowed in IMC, cannot connect.

Any advice, on how to modify a port, would be greatly appreciated?

Thanks

I have a cloud server with a public IP address of 1.1.1.1 (not the real IP). There are over 100 users on standalone PC's over 12 sites across the south of the country who have a mapped drive on their devices using the UNC path \\1.1.1.1\data. The cloud provider can't upgrade the OS on the server (it's currently server 2008) and therefore a new one needs to be provisioned. I'm migrating the AD data over and replicating the domain name etc. I somehow need to map all users to the new UNC path \\2.2.2.2\data with ease. I can't use the hostfile mapping as DNS is not involved.

The question therefore is as follows: Is there an easy way using the command line or PowerShell to route the old IP address 1.1.1.1 to the new IP address 2.2.2.2 so I don't have to re-map over 100 devices or do I suck it up and remap from scratch?

I have a copy of Cisco ACS, ver 5.3.0.40.9 that we use in our environment to authenticate port access in our Cisco switches to our AD controllers to ensure the device attaching is a company asset. Has worked great for years until 2 months ago. New MS patches break the authentication process.  In the ACS server, the message "unknown AD error" is being reported.  Anyone else run into this?  To resolve, we have to back the current patches back out. We plan on rolling out ICE next year.

Hello Experts - I'm looking for a good MSP that can assist me with helpdesk and IT projects for a medium sized architecture firm in NJ and PA. We're also looking at acquiring an office in FL so a company that has a presence up and down the east coast would be ideal. Thanks in advance for any recommendations!

Hello all and thanks for your time and expertise.  I would love your input regarding the proper permissions to delegate to an entry level tech.  The previous IT Director left my school district.  Please note he treated the Domain Admins group love a community playground as every tom, dick, and harry were allowed to be members of this powerful group.
That said I've since cleaned up this group and now only myself and another network administrator have access to this group.
However, there's a tier one tech who had access to this group who is complaining.  Please note he has zero IT background, zero certifications,  but is playing the i need access to do my job card.
He has access to the local administrator accounts to address one-to-one issues which is essentially his job.  He has full access to the imaging server to image computers and he can join and disjoin computers from the domain.  
I know as I came up through the ranks and worked on a help desk or in tier one jobs I never had server administrator access which is essentially what he wants.
I also asked him if he would like to get trained up to eventually become a server admin and he said no.
Basically if a problem required fixing dhcp, dns, AD, etc he would have no clue how to fix these things anyway so he doesn't need the access in my humble opinion.  
I'm just wondering how you good folks would deal with this issue.  I've been in IT for 25 years and have never experienced a guy with no background trying to dictate…

Have been using VisualRoute 2010 for years to help with our remote equipment installations.  In general it is helpful and can usually give me enough info to take the troubleshooting to the next step.  However, it appears that it has not been upgraded or improved in ages.  

And while it is useful, having more tools that can drill down further into latency or bad hops, etc., would be a welcomed advancement.  And I also have heard that the way it handles some situations causes it to read things as dropped packets when that is not the case.

QUESTION:  So does anyone know of a good tool that has the easy UI of VisualRoute that is more up to date and refined and powerful?  

Any help is much appreciated.  A small portion of my work relates to tracking down non functional remote equipment but it is that part of the job that is most stressful and least enjoyable.

Thanks

I have Linux 8 enterprise running on Oracle VirtualBox 6.0.10 and the network connects but I can get any traffic outside of the VM. When I run IP ADDR to get which networks are valid and then I run IFUP for those that show down I get Error: Connection activation failed: No suitable device found for this connection (device ### not available because profile is not compatible with device (mismatching interface name).

I have been going through what I can find on the web with no luck, any help is appreciated.

I am working in Service Now focusing on CMDB - the machine database. I would like to export all of the VMs and note what applications are associated with each VM. Is there a way that I, a common user, can accomplish this? I see a reports generation tool but I quickly got into the weeds with all the options. The report is very simple: Server Name, Applications

I have attempted to configure netflow v9, but I am not able to generate any flows within my 3750X switches. Should I add more configuration to my netflow module to get the flows to be read on my solarwinds NTA server? Or should I switch to netflow v5 to accomplish this task?

Here is my configuration & I am using IOS 15.2(4):
