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.

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 …

i want to be able to provide remote access to our network users so they can access their desktops from home. this is s relatively small scale affair with say 4 users on one network having remote access to their desktops from home or when on the move.

i have several sites that need this facility.

most of the products i have found seem to be for support like us wanting to access multiple sites to provide remote support.

looking at teamviewer it only allows a single connection at one time, unless you go for the corporate edition, then it provides 3.

can anyone recommend a remote access product, that is aimed at the end user getting access to their own desktops, allowing more than one connection at once?

that was one of the good parts of small business server, which we are now replacing with 2016 server running a couple of virtual machines for dc and exchange.

providing a suitable replacement for this part, is being more difficult than i imagined.

any advice appreciated.

I have tried a lot of combination of the following "route" command
all with an invalid parameter error message. I'm using the CMD with
elevated admin.  any help would be appreciated.

ROUTE ADD 192.168.0.11 MASK 255.255.255.0 172.18.135.48 yields invalid param error

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

Dear Experts

to setup new office what IP addressing is recommended as it is common to use 192.168.1.0/24 but I would like to go for something different and this network will have to be get connected over the VPN from other location and they may be using 19.168.1.0/24,  this new network yet to be setup will have internal dns and dhcp and leased line and mpls connectivity. the total users or end devices within this network will not be more than 75, I prefer other than 192.168.1.0/24 is there a recommend/best  practice in selecting a particular ip addressing for private lan network please suggest,  is it good to go with 192.168.0.1/24 or something like 192.168.100.0/24 or any other ip addressing recommended please suggest.

Anyone knows Aruba controllers well?   They normally pass through the same VLAN on the main switch, or the management VLAN.
Wonder why Aruba not recommending doing a direct heartbeat between Active and Passive controllers.  Using 7030 controllers at this point.
Normally I do a direct heartbeat between Cisco controllers.  But Cisco has a dedicated HA port for this.  Arubas not.  7030 controllers have 8 fiber and 8 copper ports.
 Anyone knows about it and have an advice?

Hi All,

Trying to copy a config from a Production switch to Backup switch that will act as a backup hot spare. I matched the ios correctly and was able to back up the config from Production, however when I restore the config to the backup switch it gives some errors because I am connecting via tftp on port 1 of the backup switch and assigned an address to connect.

Do I have to fix manually or is there a clean way of connecting via tftp and restoring. There is no usb or other connection ports in that back such as using a cross-over. Thanks in advance for you assistance

We use Emco Remote Shutdown to reboot our computers a couple times a week because I have the users only log off and not shut down.  Emco is a great product, however, the cost has now skyrocketed.

So I am asking EE if anyone has used a different product that is cost effective?

Linux admin supporting Macs.  I have a good Linux helpdesk candidate that will be require to support Macs in the future as well.  Would that be a huge knowledge curve for a good Linux admin to support Macs?  He claims almost 0% mac knowledge.
I know Linux guys very intuitive supporting Networking stuff (Cisco, etc.)  Not sure about Mac OS tho.

I have a Windows 10 PC (Version 10.0.17134 Build 17134) where a VMware is installed (Version 12.5.9 build-7535481) with Windows 10 (Enterprise N 2015 LTSB). We have a problem with the IP address of this "VMware PC". The "hosts" file in C:\Windows\System32\drivers\etc, there is the entry for the VMware PC as WIN10PC (see attachements). There is a second "hosts" file in C:\WinSxS\amd64_microsoft-windows… without any entries, but trying to add the WIN10PC entry also there fails because of the message:

Cannot save "amd64" hosts fileHowever, I have opened this hosts file only in the Notepad++ app. A ping on WIN10PC cannot find the address of 172.10.10.153 and returns the own IP address of the Windows 10 PC, which is 172.10.10.150. The arp command does not enlist the WIN10PC address of 172.10.153 at all, and an "arp -s" command will not add this IP address (see attachements). Interestingly, my colleagues can "see" the VMware machine from their PCs!

Do you have any idea what's going wrong?

Hi,

I have a pfSense router at an office I manage.  I'm not very familiar with it but I've gone through the options on it and read up about it a bit.  I'm having a problem that I'm not sure how to resolve.  The ISP has notified the office that there has been malicious requests our IP address directed at other servers.  The information they sent shows that the "PORT HIT" was "x.x.x.x:49039->x.x.x.x:23".  I found a packet capture on the pfSense and set it to listen on the LAN interface and put 49039 in for the port number.  I started the packet capture but I don't see it reporting anything nor do I know where to find the log or output of the packet capture.  It looks like this pfSense router is from a July version in 2015 so it looks like the firmware needs to be updated.  This router looks very powerful and I'd like to learn more about it.  I'm used to using Sonicwalls routers mainly so this is a little different.  Oh, and here's a real strange thing that's going on there.  I called the ISP and told them that I wasn't sure where the IP address that is reporting the malicious activity is at.  The IP on the WAN side of the router ends in 69 and the reporting IP is 71.  They said that they were not able to see any devices ARPing to that IP address at that moment.

If I check the WAN IP on one of the networks in the office (there are 7 suites--so there are at least 8 VLANs), it ends in 71.  I've scanned all 8 of the computers on that reporting network but nothing came up …

Would it be beneficial mixing up different switches models in the same office.  For example we're using C3850 access switches and need to add few more to cover the entire office.
Cisco recommends going with new C9300 for the access layer.  Would it create some operational issues?  I like to keep a consistency but like to evaluate a potential upgrade.
Advice?

Hello
I have a security requirement for my network to alert us via email when windows event logs and switches, firewalls etc, stop sending logs.

I do use Netwrix and I have been testing various syslog servers.

The requirement is:
" Where possible, configure the and network device log collectors to generate an alert in the event a device stops sending logs to the centralized log collector for 24 hours."

Does anyone have any experience with accomplishing this? What tools are you using to automatically generate alerts when logs stop?

I am open to using any Microsoft or 3rd party tool to make this happen.

Thanks
