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.

Hello, we have a staff of 20, and we want to track websites and bandwidth used by workstation/user. What's the best tool to do this?

ISP making a demark  drop inside my new server room.   I don't want to find out last minute there's no signal or lower bandwidth than ordered.
Is there a reasonably inexpensive device that can show the signal and can test speed?  Or any other ways?
 This is for LC Fibre 1Gb multimode.  Thanks.

I have an older Cisco 7301 router from 2005; that I want to use in the new office as a temp solution.

It has 3 SPF GBIC ports.  Can I use any SPF transceivers or only Cisco specific.  I have few from Juniper 10GBASE 70C.  
Would that work?

We have apps that send alerts out via SNMP (think it's v2 SNMP): is there any way these
events are sent to an SMTP server (we use Exchange) or to SolarWind (our monitoring tool)?
If sent to SolarWind, we want to be alerted via email or SMS.

Our apps read the events from a custom Oracle DB (from a SWIFT application).

We have Splunk SIEM being deployed but not ready yet so wanted to use the other 2 options 1st.

Dear Wizards, is there any free solution for logging management? I found Greylog on the Internet but not sure about its quality. Can you recommend some? Can Zabbiz be used for logging? Many thanks!

I am writing a netflow collector in .net, which has lots of interesting challenges including reading the RFC!

However, I need a specific piece of information  

Here is a link to a copy of the RFC:

https://www.ietf.org/rfc/rfc3954.txt


From this I read this excerpt:
The life of a template at the Collector is limited to a fixed refresh
   timeout.  Templates not refreshed from the Exporter within the
   timeout are expired at the Collector.  The Collector MUST NOT attempt
   to decode the Flow or Options Data Records with an expired Template.

I cannot find any default expiry timeframe for a netflow Flowset Template.  

It says it must be configurable at the exporter and the collector.  When I set up a PRTG to collect netflow packets, there was not an option to specify the template expiry.  I can't see any record in the RFC that the exported can use to tell the collector when to expire templates.  PRTG works though.  

Therefore there must be a reasonable default value for how long to keep an un-refreshed template before expiring it.  

My question is, what is the default timeframe to expire a template - OR - how else can the collector learn this from the exporter? (someone manually configuring it is not the answer I want)

There must be some way in which netflow collectors work out of the box without the user specifying the template expiry.  I need to do this.

I have a situation.  Moving users to the new office.  Cisco gear however 4 to 6 weeks delayed.  Looking for a temp solution.  
I have a Juniper EX4300 switch.   Can I configure it as layer 3 as a router to serve the purpose.  Would that be any difference than having a router?  It should have GBIC ports for ISP.   And enough mbit ports for the users.   There should be only 10-15 users initially.

Any other temp ideas guys?  Thanks.

I am using MRTG to monitor a charge controller at a remote site. I can graph the voltage of the solar panels and the battery bank.
It nicely displays the maximum, average and current values for the period of the graph.
I am not very interested in knowing the maximum value of the battery voltage at night because it won't ever be higher than it is at sunset. I would like to see the minimum voltage for the overnight period. That would help me decide if more or fewer batteries are needed to store the power.

The configuration is as follows:
Target[PacketFluxVoltage]: 1.3.6.1.4.1.32050.2.1.27.5.10&1.3.6.1.4.1.32050.2.1.27.5.11:zzzzzzzzzzzzzzzzzzzzz@192.168.130.140:

What are the best types of 5 port POE switches that can have Comcast Power over Ethernet (POE) phones plugged into them?

An office where I work with have two Comcast POE phones but has only one Ethernet port. We need to connect a switch to it so we can plug in both of the Comcast POE phones as well as two laptops.

What are the best types of switches for this?

I have this config on cisco 3650 switch:
enable secret 5 $1$CjMf$vnUDcs1IGZSNACW
enable password 7 03124C0F0F5E79
!
username admin privilege 15 secret 5 $1$8zl1$kGUgJ5pHTOyz2
username tech privilege 15 secret 5 $1$QsH.$G.R4BJBhZh6K6jA

when I telnet it asks for username and password. When I enter username and password  it goes directly to: #_

How to go to: >_ and then to ask for another password?

Dear Wizards, will Zabbix SNMP agent affect the overall network performance?

For example if we use Templates for SNMP devices, it has 270 items. They are many options which we are not sure are really needed? If we enable all of them, will they slow down the LAN network?

Many thanks for your support!

I downloaded and install the free SolarWinds Real-Time Bandwidth Monitor. I need help to configure it. Its asking for the Community String. What's the Community String? Where do I find it?

We support a church that uses electronic hymnals via an app on their mobile devices. During services they can have up to 500 members trying to connect to 4 Sonicpoint's with the same SSID. My question is, Is there a way for the sonicpoints or the firewall to distribute the user connections equally between the AP's?  

Right now most users can't connect and the ones that are have terrible connections (speed). Which I assume everyone is connecting to just one AP.

I thought about sectioning off the pews RF,LF,RR,LR . Then create SSID's associated to those sections. But there has to be a better way.

Thanks in advance for your help.

What are the risks if MS NAC is installed in the AD/DC server (to save the cost of setting another
dedicated NAC server) & how can we mitigate this?

Was told NAC works by per L2 switch and not by per port?  Care to elaborate what my Network colleague said?

What specific ‘maintenance’ tasks in terms of IT are typically required once an employee has left an organisation? I wanted to do some spot checks to ensure they were being followed within our company, and 2 areas aside from the obvious ‘delete their AD account after a pre-defined amount of time disabled, was to also probably delete their mailbox and their home drives, but wanted to see if anyone else could share any other common ‘maintenance tasks’ if it’s in a checklist form so I can do some checks in our company to ensure they are being adhered to.

Do you have any specific best practices or processes you follow when it comes to management of your AD user list when employees are temporary. From a security angle there are routine reports provided by HR in relation to users who have left employment, or transferred to a new role. But often temp/agency staffs are not recorded in your HR system at all so slip the net. Just wondering what controls you have in place to ensure temp agency staff are effectively maintained, e.g. deleted once their temporary contract has ended.

We already have SonicWall CGSS but that doesn't allow us to audit what websites a person or group of people are visiting. Any services / programs out there that will do that without going to Untangle or something cost prohibitive like that?

Hello:
We are using a Sonicwall TZ 205 firewall behind a Barracuda Link Balancer 330. I have two ISP connections coming into the Barracuda (Sprint and Comcast). I have 5 public IPs from each ISP. We currently have the following servers behind the firewall (Exchange 2013, Microsoft Remote Access for VPN and an ISeries database server) that are accessed using the Sprint public IPs.

Internet ---Sprint Router (65.xxx.xxx.17)

Internet ---Comcast Router (173.xxx.xxx.142)

                  |
Barracuda Link Balancer 330 (65.xxx.xxx.18 and 173.xxx.xxx.139)
                  
                  |
Sonicwall TZ205 (65.xxx.xxx.20)

                  |
Internal Servers

In the Sonicwall, the Sprint public IPs are all NAT's to the internal private IPs.

 I would like to setup some inbound redundancy for these servers by mapping them to some of the Comcast public IPs. The Barracuda has only one connection to the Sonicwall so I don't know if I need to add another physical interface to the Sonicwall on interface X2 and configure it with the Comcast information and then put a switch between the Barracuda and Sonicwall. I know how to setup the DNS records to check if one line goes down, but I am unsure as to the physical connections.

Thank you.

I'm looking for utilities/methods to monitor my organization's Server 2016 network that will let me know (via email alerts) any time that these items go offline:

- Server 2016 AD domain controllers
- Wireless Access Points (WAPs)
- Network Attached Storage Device (NAS)
- SonicWALL firewall
- Primary internet service
- Fail over internet service

I am also interested in any monitoring solutions that will let me know if the Server 2016 hard drives are running low on space, etc.

What are some good website services or other software that will allow this to be done using methods such as pings or SNMP monitoring?

I've been struggling with VOIP call quality. One thing I notice is where calls to PSTN or Conference are made from work on the west coast or from home on the west coast - the traffic takes a 100ms trip to the east coast to get to the Skype voice control and RTP gateways. Is there any way this can be altered so you can use gateways on the west coast to reduce hops and delay to the Skype voice gateways?

I have a SonicPoint ACe and we're using it as an AP for public wifi, so it's not attached to the SonicWall FireWall, since the SonicPoint is in standalone mode, I can't enable the 2.4/5 radios in wireless router mode.

I Have 3 Switsches A,B,C

Switch A is connectet to B, Switch B is Connected to Switch C

Switch A is configured
spanning-tree vlan 1-4094 priority 8192

Switch B is configured
spanning-tree vlan 1-4094 priority 16384

Switch C is Configured
spanning-tree vlan 1-4094 priority 24576

Now I will Chang the Values

SW C gets 8192
Sw A gets 24576

Is there any disruption taking place by a new spf calculation, even if the Switches in a Row?

Looking to add a Skills table to a database of IT Consultants. Can anyone point me to a list of skills required by a large IT department? I'm thinking even a solid list of current enterprise programming languages would help.

Thanks
