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.

Please take a quick look at this Aruba WAP design and let me know if there anything can do better there.  Or if there anything I should change.
Are the Aruba controllers HA with a heartbeat cable between each other or over the switch?
I will have about 10 APs.  
Does it make sense for x2 Mobility Masters in different geo locations?

Any  other tips please let me know.  Thanks!

Question.  Our new office prewired with CAT6a all the way.  From users stations to the patch panels.
Does it make sense to have CAT6a for the users stations as well?  Desk ports to the computers.
And from patch panels to the switches.  
What about from other devices to the switches?  WAPs, FW, routers, between switches, etc.  Go with CAT6a all the way?

We are setting up a new domain, designated for a critical sensitive applications with its own AD/DC.

Is it Ok for the AD/DC servers to sit in same subnet as the apps servers    Or
should we segregate into separate subnets?

If separate subnets, segregate by router ACL is enough or firewall?

What's the reason & the best practices out there?

Hi

I had created a SITE to SITE VPN between a PFSENSE anda Sonic Wall TZ400.The VPN is up no problem. The only thing is that I cannot open ressources like folders, rdp or ping from one side to another. Anybody knows where I should look to fix this issu?

Thanks

One of the Experts here on EE suggested GFI Languard.  So, we bought it and have  had it running for a few months.  As I get further into it and want to take advantage of its capabilities, I naturally have questions.

Being a "good customer" I figured to start on the community forum.  But I can't log in and I can't set up a new account.  I have LOTS of email addresses available and can set up new ones.  Yet, no matter which one I enter for a new Registration, it says "already used".  Can't be true of course.

Telephone customer support takes one to a menu that has nothing to do with customer support and, if you politely wait after not responding, it says "Goodbye".

I may be in the market for 3rd party Q&A at least.  Or, what might you suggest?

Dear all,

I am an IT support for a small company consist of 5 users. I assigned a static IP address on each computer.
Around 3 weeks one of my colleague was not able to browse the connection or see the shared folder on the server until I changed his PC's IP address. This issue reoccurred again today on his PC and on another PC.
I have done a lot of troubleshooting and the last step was changing the IP address. After changing the IP address on two PCs they were able to browse the internet connection and see the shared drives.

I am wondering what is the magician with changing the IP address. Please assist me because I am looking for a solution to avoid keep changing the IP addresses form time to time.

Hi Guys,

We have an IP block from the ISP
Thus a couple of public IP's assigned, example:
196.31.231.80
196.31.231.81
196.31.231.82

Our NAT policies on 196.31.231.80 over X1 interface is working well.

I've been trying to setup additional NAT policies on 196.31.231.81, but experiencing a connection issue.
Which brings me to the following questions:

1.  Is it necessary to setup a Virtual Interface for 196.31.231.82 on X1?
(255.255.255.0)
Or could the NAT rules simply refer to X1?

2.  I tried setting up a Virtual Interface on X1 for 196.31.231.82, but it complains about the same subnet used,
What should the subnet for the Virtual Interface be?

Hello everyone,
A client of mine is having an issue with their wireless.  They have been reporting that the passwords were getting rejected so I updated the passwords and then the same thing.  I have tried rebooting it, which normally used to fix these issues but now does not.  They have two ssids, one for employees and one for guest and they are configured in a virtual access point.  There are no more firmware upgrades for this model, my next step would normally be to upgrade the firmware.  We have recommended upgrading this Sonicwall as it is no longer supported as well as having a separate access point in the past.  I honestly think that this would be the only solution at this point, but out of good customer service I am reaching out to you guys to see if there is anything else that I can try.

I am upgrading the Comware 5 firmware on HP 5120 switches HP 5120-48G-PoE+ EI Switch Product # JG237A. In the past I have upgraded them with they are offline.  I would use my laptop as a TFTP server, connect it to a port on the switch, and put my laptop IP address and switch management IP address on the same subnet. I would use the following commands (for example):

delete /unreserved flash:/<firmware>

tftp <IP Address> put flash:/<firmware>

boot-loader file flash:/<firmware>

save

reboot

Would I be able to do this with a live HP 5120 switch connected to the production network and grab the firmware off a live tftp server on the production network?

Please help. Thank you.

I need to add one of our vendors IP's to our Sonicwall so they are not blocked.

How?

I need to update a bunch of catalyst switches from TLSv1.1 to TLSv1.2. Also need to disable older ciphers. Has anyone implemented this before?

Please share the steps as I can't seem to find anything documentation online for this.

Thank you.

hi guys,

I'm currently managing an IT Operations team. I've been asked by our new head to come up with a way for me/us to measure in some shape or form their progress on a weekly basis.

We use Zendesk for our ticketing system which is very comprehensive. He wants us to find a way of knowing, how many particular jobs were started, closed, including things such as 'what got in the way?'. Along with that, he wants to know a way of measuring project progress in a similar way.

Do you guys have any measuring methods that you use at your work places? Or advised others on how to better do something similar?

Thanks for helping

HI
I'm just implementing a DPI inspection and I've download a key from my sonicwall firewall.
This cert. has been distributed to my PC over GPO.
How do I distribute the same cert to my MAC clients  ??

my network is as follows:

Comcast 10.1.10.1

Sonic Wall - 10.1.10.2 (gateway 192.168.1.1)


Just double checking, I want the SonicWALL subnet to be private.  I am a little concerned because when I am on a workstation behind the sonic wall I can ping the Comcast gateway, and navigate to the admin portal.

However, when I am directly plugged into the Comcast gateway I cannot ping the 1.1 gateway subnet.  So the SonicWALL subnet is not visible to the main comcast network.  Is my network setup and secured as intended?

Where i work has a large number of DHCP scopes. must be approx 40-50 its been left that way for a good few years apparently

I have just joined in past 6 months and just getting round to look at it now

Any DHCP scope clean up plans? Whats the worst thing that can happen if some are removed that have VLAN connections (one thing we're worried about) so i plan on taking an inventory first

I know i can use powershell to look for free addresses per scope can i use this to see addresses that are taken, then i could compare using HP IMC to see whats actually being used

Any ideas appreciated domain functionality is 2008

Working in environment with 34 switches mix of hp 5500 and 5120s over 3 locations

I suspect that the company who support our infrastructure just took the default priority for spanning tree design with switches

I intend to check each BID on each switch is there an argument for using default settings for stp would appreciate best practice on this and and also pointers on easiest way to correct it

I have login for each switch but also use HP IMC

Thanks,

We have a connection to the Internet and now we just added another Internet connection. We want to use the new Internet connection just for Office 365. I am not sure how to go about doing this as I have a default route from my core to the FW and then from the FW to the provider router. So currently all Internet connection, including O365, is pointed to the default route and there is nothing going out of the the new Internet connection.
We have a physical connection from the provider to the FW, then from the FW to the core switch.

Any thoughts? Thanks

I currently have a SonicWALL TZ 200 configured with WAN connections on 2 interfaces. I recently purchased a HughesNET satellite connection and I want hook this up to the SonicWALL (And add it to the failover/load balancing). However, once I received the Modem from HughesNET (HT2000) I learned that it does not have a "Bridge" mode built into the router. I cannot disrupt my current Subnet (needs to stay the same). Does anyone know if there a way to configure the interface for the modem/router combo into the SonicWALL so it will work properly?

Thanks in advance.

In addition, can this switch become a DHCP server?  I dont believe so as the doc mention considerations when the switch receives DHCP config - but nothing on creating them. But I need to ask.  I will need a simple DHCP server for this assembly (SIP Phones using Free PBX) and using the switch would be ideal if it did work like that.

I have a client with whom I've set up a home group. He's got 3 computers with each having Windows 7 installed. Every evening he leaves his shop, every morning when he comes in, his computers and two HP printers have lost their connectivity. The home group eventually regains its settings, but he has to setup his printers from scratch. He changed routers recently. Before his router change, his network had no problems.
