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 am trying to install SSL certificate on F5, I keep getting Import error (Screenshot attached) I have tried entering password, and changing the option for Key security, it doesnt work.

The certificate i am selecting is in .pem format, have selected .crt and .p7b as well, none of them works.

Have anyone experienced the same error?

Is there a way to tell if a local group on a 2012 server was deleted and by who made the change and when it happened? Not AD groups, but the local groups on the machine, ie.. Remote Desktop Users, Power Users, ADSyncAdmins, etc..

Also, if a service was changed or reset to it's default settings, is there a change log of this on server 2012 to see who/when it happened?

Hi guys

I'm currently managing an entire infrastructure team at the moment and we've hired a third party to monitor all of our servers and infrastructure for us in the case of an emergency, so that they can handle it whilst we are all in lala land;). However, one issue I do have is that we do not have something like a 'runbook' which they can refer to. Now, I know that creating a run book can vary from company to company. Our systems consist of an infrastructure with many virtual machines, each of these virtual machines has a variety of applications running on them, some of them have POS systems, databases with SQL, order fullfilment systems etc.

If you were to have a runbook, how would you have yours and what would it consist of?

Any help would be great.
Thanks for looking

U-verse WIFI Extender on AT&T Internet 100 still intermittently drops U-verse, WIFI which is resolved  by rebooting everything. Bizarre, less than 2500 sq ft so the Att Smart Extender shouldn’t even be needed yet we installed it to test. Syncd ok and improved some. Have a second other extender; different mfg type. Any downside to using 2 to test?  All HW devices from ATT have been either replaced or upgraded. The intermittent dropping of signals at somewhat repeating times of night kind of nuts!

insights appreciated.

I'm looking for some help re-configuring my home network. Here is current setup:

Comcast cable comes into data enclosure in garage wall to a 2-way Splitter. One coax goes to Gateway in my office. Patch cable out of Gateway to a switch beside it which connects my desktop and network printer. Patch cable from this switch to the wall jack backfeeds back to the data enclosure in the garage. Patch panels in the data enclosure connect to small switch in the data enclosure to provide network to other jacks in house.

First, I'm planning to ditch the Comcast Gateway and go with my own modem and router. I want to add a Ubiquiti Cloud Key Gen 2 Plus and eventually a couple of security cameras as well. I'd like to centralize things a bit more instead of going to my office and then backfeed to the data enclosure before distributing to the rest of the house. Unfortunately, there isn't room in the data enclosure for the router, modem, etc. and even if there was, I'd be concerned about the temps. It can get pretty hot in the garage (90F+).

The room directly above the data enclosure in the garage is a storage room with heat and A/C. Perfect location for the network equipment. And it has a knee wall I can get behind and access the cables going down into the garage.  But I'm not sure how best to proceed.

There are 17 Cat5e cables coming into that data enclosure in the garage, 7 from top (upstairs jacks) and 10 from bottom (downstairs jacks). There appears to be enough length on the …

We are using EAP-TLS on our Microsoft NPS 2012 R2 server. Everything was working fine then I had to update PKI from SHA1 to SHA2, pki is healthy and certs have been distributed domain wide. For some reason I cant get the wireless EAP-TLS policy to work.

Dear Experts

We are planning to implement surveillance system in our factory for 24/7 recording footage and approximately 25 to 30 cameras  with feature of Night Motion Detection,  we prefer to have backups scheduled and replicated to head office our  factory and head office are connected with MPLS network. Synology has Surveillance solution would like understand does this serve the above requirement, it is also very much important for us to have every 4 hours backup and the same is secured and copy to the head office hence NAS box replication is required, please suggest.

Hi,

We have 2 x Aruba 8320s (Core Switches) We also have 11 x Aruba 2540 edge switches

Each switch has 2 x 10Gbe SFP modules which connect to the cores via fibre in a LAG.

The switches are split up in 5 separate racks across our building. We also have 1 x Meraki switch in each of the cabinets capable of have 10Gbe SFP modules.

My question is what is the best way to get the Meraki switches to communicate with our Cores? We want to utilise them.

1. Direct connection to the Cores (like the Aruba's)
2. Setup a trunk 10Gbe between the edge switches and Aruba's
3. Any other way?

Could you please advise?

Thanks

We have a Cisco 6509E chassis as the core of our network.  We are trying to run our FOG (Imaging software) server and we are finding multicast is not working through the switch.  We tested this by plugging the server into a variety of other switches that bypass the core and multicasting works perfectly.  I am unsure what settings could be different as I have compared IGMP Snooping and the portfast settings with the switches that work when the server is plugged into them.  

Any ideas?  It is running SUPT2XL as the supervisors running 15.1 on them.

Hi,
I have Dell PowerEdge R510 server.

The Goal: To reset the iDRAC

The things that I do:

I find the “I” switch (It is at the front panel of the machine)> I press that “I” switch around 30 sec> then,  I release it.

The outcome: I saw the DISPLAY blinking  blinking  continuously (Not Stop).

My question:

1) How can I know that  the “reset” has been successful?
2) Is there any other way to reset this iDRAC? Which ones?

Thanks,
Tjie

I have an old network diagram that has a .DSD extension.  Anyone know of a reliable program I can use to open it?

Hello, I am aware that classful network addressing is a thing of the past and there are 5 classes.
            Prefix
Class A       0
Class B       10
Class C       110
Class D       1110
Class E       1111

If we wanted 9 Classes I’m trying to find the leading bits. Is this possible?

Thanks.

Hi,

Recently had a broadcast storm we found it by running sh int and the port with errors we shut down and the storm stopped. In trying to research what other steps we could take, came across the command below and it reported multiple ports below including the one below with receiving broadcasts, is that normal or is it something we need to look at and address.

 Also any general advice of commands we can run to check for broadcasts on our networks

show interface | include (.*Ethernet)|(.*broadcast)

GigabitEthernet3/0/47 is up, line protocol is up (connected)
  Hardware is Gigabit Ethernet, address is f8a5.c5bd.ab2f (bia f8a5.c5bd.ab2f)
     Received 1071365 broadcasts (517836 multicasts)

How do I handle this scenario:

A web service will receive data and write to a file on a network share.
Another application is running as a service that checks for files, reads the data, processes, saves the data to a database then deletes the file.
This application must run in multiple data centers and on multiple servers in each data center.  How do I ensure that each file is processed
only once.

I'm going to be giving a domain controller a new IP address.  what else do I need to change IP wise on the DC apart from the NIC Ip

OK. This is going to be simple for those who are into networking and VLANs.
We recently got fiber from our ISP.
After media converter, we have one LAN cable.

It carries two VLANs.
VLAN 308 internet service for the entire company
VLAN 309 l2vpn service to connect to remote office

I need to configure my L2 SW and router in HQ to untangle this.
Our default VLAN is 1.

Can someone please provide the simplest solution on how to configure ports on SW/router?

In Azure I am creating a storage account, but need it to be accessible from our vNet's only.  During the Storage Account setup you can specify a vNet. The problem is we have two separate vNets in two different regions that needs access to this account. Instead of using vNet can we create a NSG for our Storage Account?

We have a medium size network that is down as a result of what appears to be a broadcast storm. We powered down all switches. Then, we disconnected all devices on the switches. Next we connected devices one at a time. All seemed to be going well until about 3/4 thru the process (48 port switch). All of a sudden the all the led indicators started blinking again.  We reversed the process, unplugging connections one by one (with a 1-2 minute wait between). The issue did not go away. The primary switch we were working with was a Dell. All other switches are Dell with the exception of a few smaller switches in offices where it was easier to place a switch than run new cable(s). Does anyone have any suggestions?

Hello Experts,

Its been long time I never did this in a cisco switch.

I want to provide https access to a client that wants to check the port status on the switch but I only him to access the url link with minimum access rights so he can not do any changes. I can access the switch URL using my admin account.

1. I want to create a local account with lowest level
2. I want to login with that account and make sure that account can see the switch and the ports that are up and down.

Please note that this person is non - IT but we want to make sure at midnight he can check it the ports are up for mission critical environment.

Thanks,
