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.

We would like to monitor when a server, switch, router, and firewall goes down. We have a remote site that's "unattended", however, we would like to keep an eye when a device mentioned before goes down?

Do you have a suggestion that we can consider? Thanks so much.

Hi guys

Do you have a checklist that you go through for your network infrastructure on a daily basis that you are able to upload at all? We have one, but I was just keen to see what others are using and perhaps add the things (if relevant) to or list?

We do checks for fileserver space, VPN tunnels, backups, alerts for Vmware and Firewalls.

Thanks for helping

I need to factory default a Calyptix AE800.  I took over this network from an IT company who will not share the login information.  I can't find any information on line, and there is no reset button on it.  Anyone who can help would be appreciated!  Thanks!

There is an IP address in South Korea that has been probing my router for weeks now.  I have them blocked, but I would like to report them to some entity/agency that can get it shut down.  They will hit a single UDP port once a second for 20 seconds.  Then there will be a pause of 2 to 5 minutes and they will try again on a different port number.  What is the best way to handle this?

We would like to introduce 802.1x on our Cisco switches. The environment consists of various devices (printers, phones, scanners etc) which may or may not be 802.1x aware. I know that we can use MBAC to get them to authenticate using MAC addresses, however I'm wondering what needs to be done for the users desktops and laptops.

The users devices are all Windows 10. Does the operating system have the relevant configuration/controls/software already built-in or do you need specific supplicant software installed to get it to work? I'm speculating we could install a RADIUS server on an existing Windows server (2012) to provide the AAA aspect? Are there any good articles that describe how to set it all up?

Hi guys, non-technical question here.
 Does anyone have any format or an example for the new hire justification.  Instead of asking management "hey can I hire someone to help me, I am working 12 hrs per day"
Maybe someone has previous example or a set format showing the following things or similar:

1) Justify why you need help.
2) Explain your current situation, hours and work load
3) Tell how a new hire/resource will benefit the company, for example, improved revenue by 5%, completion of projects 25% faster, improved customer satisfaction rating, etc.
4) Justify the cost and how the proceeds will offset that person.
5) Show the long term strategy of this person and how this person fits into the organization
6) Show your new role on you being the manager and how this will free up your time for more strategic goals
7) Finally, show how this new hire aligns with company strategy and direction and how your department will be able to meet or exceed those goals.

Appreciate any help/advice.

Dear Office 365 Experts,
I would like to find out what articles/videos you'd like to share for the best practice/required network connectivity for Office 365. Our network folks do not have any background and or vision as to where to go or what to do, so anyone that could shed some info, would be greatly appreciated. I know we should/can involve an MS resource but just wanted to prep/use some background info in parallel that they can work on/read about.

Thanks!

Anyone here have experience implementing and managing a good parental control app on their child's iOS device(s)?

I'd prefer one that does not utilize a VPN (too easy to disable) and does not require the client to be on wifi. It should function on both LTE and WiFi. I don't care if the product is overly complex. I just want a reliable tool to be able to monitor usage, disable Internet access on the fly, potentially set time limits at the app-level and make sure the entire app can't be easily skirted by my kid.

There are so many different products on the market, there are hundreds of unhelpful review sites and the actual app-store 'user reviews' are full of negative comments made by people who have minimal technical experience. It's made the process of narrowing down the selection, extremely cumbersome.

I'd like to hear your personal experience with specific apps and what the shortcomings were that you ran up against. I expect I'll have to make concessions as far as functionality goes, so I'm hoping to hear about potential dealbreakers.

Webinar: Miercom Evaluates Wi-Fi Security

It's not just about Wi-Fi connectivity anymore. A wireless security breach can cost your business large amounts of time, trouble, and expense. Plus, hear first-hand from Miercom how WatchGuard's Wi-Fi security stacks up against the competition in our upcoming webinar!

We have a scheduled power outage in the small remote office.  Mostly network gear.  Few switches and firewalls.  No servers.
I know the UPS wouldn't be able to hold that long.  
What's should be the advised steps?   Shutdown the equipment prior to the outage and have someone onsite to startup after?  
How other folks doing it?  
Thanks in advance

Never done that and need advice how its being done normally.

I need to relocate uplink one floor up in the building.  Larger server room, better AC, power, etc.
Moving all the switches up there.  How do I move the ISP handoff?  Fiber single-mode.
Do I just put a patch panel and route up there, or move the handoff?  Is it something ISP responsible per request or cabling contractors?
What's the best option?  Please advice.

Hi,

as attach file show, I have two firewalls, one is too old and could not support VRRP, but I want to make a backup route.

so I write two default route on Core switch:
ip route 0.0.0.0 0.0.0.0 192.168.1.1
ip route 0.0.0.0 0.0.0.0 192.168.2.1

I don't know if there will be problems.

if 192.168.1.1 is broken, the traffic will through 192.168.2.1?

Regards,
Kai

Are all 48 Ethernet ports on a Cisco Catalyst 3560 series POE-48 switch Gigabit?

This is a Cisco Catalyst 3560 Series 48-Port PoE Ethernet Switch WS-C3560-48PS-S V04

The serial number of this switch is CAT0941Z2VC.

The reason I ask is because I have plugged in two laptops (a Lenovo T450 & Lenovo T470) that both have Gigabit Ethernet ports using network cables and the speed that Windows reports these laptops are connected to the LAN at is 100 Mbps.

I bought this switch used and according to the seller, it has been reset to factory default settings.

This switch is running iOS version 12.2.(25).SEB4.

Or do I need to login to the switch to enable Gigabit connection speeds?

Dear Experts, is there any limitation  in NAT overload entries in Router Cisco 3925 ?

We have about 200 users, using NAT overload of an access list via exit interface (in Router) to go to Internet. However, sometimes few PCs in a subnet could NOT go to the Internet, then I had to add this subnet to another ACL to use NAT overload via a public address pool, to allow those PC go to Internet.

Can you please explain and suggest? Many thanks!

hi guys

I was hoping that you guys could help me with something. We have many stores across the UK. I am trying to do a revision of our network architecture. I have uploaded a very basic Visio diagram of what it looks like. Stores are connected via the MPLS to a datacentre which has our firewall and from which the internet breaks out. I have created Store A and this configuration is almost identical for all other stores. All stores have IP PDQ machines. The store network traffic goes from the PC's, Tills//PDQ's via the MPLS network to our datacentre and from there, it breaks out to the internet. PDQ's also failover to an analogue telephone line if there is an issue with the MPLS network.

We have additional internet lines at each store for other things such as footfall camera's and mobile devices which I have included on the right hand side. This is so that credit card information is going out of an entirely separate line in case of a breach. So of course, one issue we have is that if (this has not happened yet in the 4yrs I have been there) the internet side at the end of where the MPLS breaks out into the firewall and to the internet went down, then none of the 40 stores can transact properly. Well they can, but via the analogue phone lines which I think is just 20th century rather than 21st.

However, I am reviewing all of this and hoping that we can just reduce 2 to 3 internet lines into just one and introduce VLAN's and consolidate everything.

My questions …

Hi guys

I'm currently working on all of the licenses across our estate. I ran the Microsoft SAM tool and of course in the report we have so many users/mailboxes/devices which are over the licenses we actually have.

I'm trying to work out a way which I can get a report into an Excel sheet with the following to help me with all of the licensing:

a.  All of the people who have not accessed their mailboxes for over 2 months (the plan is to backup and then remove those mailboxes)
b. All of the mobile devices that have got Exchange emails added to them.
c. All of the computer devices that have not accessed or been active or no longer on the network.

Is this feasible? As it will hopefully help with getting rid of stale and unused records to aid me with organising our licenses.

Thanks a lot for helping
Yashy
