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.

Why would wireshark shade certain lines of a packet capture grey instead of light blue which is the majority?

In the DHCP scope options 006 DNS Servers.  
Is it required to put all AD DNS servers there?  I got two in this case.
Also, is it a good idea to put google dns as 3rd option 8.8.8.8 ?

Do I really need a reverse DNS zone?  This place never had it on bind dns and worked ok for years.  and it did't create on AD Windows DNS either.
Do I really need to create that? and would it cause an issue if I don't.

What processes can I follow to set up an email alert to let me know when a certain user with domain admin rights has logged onto a Server 2016 domain controller?

I am setting up SNMP for the first time.  I installed the service on a member server.  Added the Public to the Community.  Started the SMNP Trap on two of the other servers, both are DC's.
When I try to add the service using PRTG MNetwork Monitoring it fails.

What steps am I missing in the setup of SNMP

We have one client purchase 2 MX64 and 1 X MS250 For the beginning i design to create the vlan2,3,4 in MX and also DHCP.

My thinking is we have the 2 unit MX64 so i can configure as warm spare.if one unit MX is down so another MX will be can active and all the function will not impact to user.

But recently we receive msg from customer IT team .They would like configure VLANs in MS250 and throw the default route to MX .

May i know what are the benefit to configure DHCP and inter-vlan in switch and please advice which method is better

I upgraded our SonicWall at the beginning of the year and have some confusion regarding SonicOS's  CFS.  The device is running SonicOS Enhanced 6.5.0.2-8n.

(1) Is there a way to get a log of *ALL* CFS entries?  When I look under:

Log Settings > Base Setup > Security Services > Content Filter

It shows:

CFS Alert = 1461
Website Accessed = 16
Website Blocked = 14

However, I can't figure out how to get to that log.

(2) Is there a way for me to be emailed anytime someone gets the "blocked" screen with the details shown on the block screen they see?

TIA.

We have 3 wan connections going into a bonder - Bell (200mbps) Rogers (200mbps) and Shaw (150mbps) and then from the bonder into X1 interface of the sonicwal (NSA 3500). From the bonder direct out we are getting about 320mbps (which is not great and we are working with Rogers & Shaw to improve their connections) but from the clients we are only getting a max of 95mbps up and down no matter how many tests we run. I have tried this on the X1 and X2 interface as well as change to the secondary HA unit and I get the same results.

I also plugged in my laptop directly to the Bell connection and was getting about 180 up and down. Plugged into the sonicwall X2 interface and changed my client to use that route and again I was getting a best of 95mbps.

Seems like this problem points to the sonicwall

I have a case open with them but wanted to try and resolve this sooner than later so any help/insight you have would be appreciated!

When the user domain_aislas was trying to authenticate with NA domain AD, EMEA domain AD , the authentication failed -through wireless

when using LAN CAT 5 it works

When the same user came across LA Domain AD the authentication succeeded.  

Authentication failure from Clearpass
=====================================
NA domain AD - 10.130.x.x: User not found.
MSCHAP: Authentication failed
EAP-MSCHAPv2: User authentication failure


Service groups and the AD servers in Clearpass
==============================================
1. NA_Enterprise wireless access ( Authentication for the user a_aislas failed here )

here all doamins are parent child relationship


is it a subnet issue

I am familiar with making DHCP reservations in Windows Server But am now doing in SonicWALL TZ 215 I can see how this is done, But have some questions when doing this in the ARP section:

What does it mean to Publish Entry?

I assume that I want to bind the MAC address or why would I be setting this up in  the first place?

What is meant by Update IP address dynamically?

In the big picture the user will use PPTP from the Windows server to VPN in.  They have a business app that is Unix based and requires the client system to maintain the same IP address (reservation or static).  So, I need the client to obtain that same IP whether they are in the office or out on the road.

Thank you.

I've got a NETGEAR  GS724T V4 Managed switch with a VLAN set up using the Auto VoIP setting for 6 ports to serve VoIP phones at a client's location. The other ports are set to default. The IP for the switch is 192.168.1.200.  The switch is on a 192.168.1.1 network.


1) Do I need to set up another subnet for this VLAN (192.168.2.1), or will these ports just be isolated from the traffic on the other ports of this switch.
2) If I do need to set another subnet, how do I set either static IPs or DHCP for these 6 ports on the subnet?

Thanks lots for your insight.

home network devices not finding new SonicWall SOHO Wireless.  It also is not being detected on my phone.

I ran the network tool 'IPerf" on 2 PC's that are connected by several GB Switches.  The results are pretty close every time I ran the test, please see below

G:\Downloads\Iperf\From_France\files>iperf.exe -c XXX.XXX.XXX.151
------------------------------------------------------------
Client connecting to XXX.XXX.XXX.151, TCP port 5001
TCP window size: 64.0 KByte (default)
------------------------------------------------------------
[  3] local XXX.XXX.XXX.151 port 64114 connected with XXX.XXX.XXX.151 port 5001
[ ID] Interval       Transfer     Bandwidth
[  3]  0.0-10.0 sec   719 MBytes   603 Mbits/sec

--------------------------------------------------------

My question is this acceptable for a GB switch network?  I suppose if you take 603 and divide into 719 that is 83%; but, I have no frame of reference.  I would think that the power of the computers make a difference as well; but, can someone explain to me:

Question1: What is considered good bandwidth results for a GB LAN connection?

Question2:  What is considered bad babdwidth results for a GB LAN connection?

Question3:  How can I make a definitive test using Iperf?  or any other utility?

Dear Experts, we realized some abnormal traffic on my Cisco 3925 router when issued command: "show processes cpu, show ip flow top-talker, show ip nat translations" and blocked some IPs which were strange, but the other keep coming to attack us on port 389.

Is there any way to configure the Router so that it can react automatically? for example: block IP when the connection is higher than the pre-defined threshold? my router's CPU is 17-25%, is it too high? normally at offpeak time, it's just about 10%

Please suggest. Many thanks as always!

Is there a simple method for manually sending a test trap? I know traps are getting to the server, but to troubleshoot further, I need an easy way to send a test trap to my receiver manually.

Dear Experts, I saw this error in logging of Cisco Router C3925. Could you please suggest and explain?



The Src address is the Public IP address of this Router (and it was hidden), a Dest address is the Access point's private IP address. This is a diagram:

ISP --------- Router C3925 ------------ Core switch 3750 -------------- Access switch 2960 ------------- Access point Meraki

Many thanks as always!

HI,

I have cisco router RV016 with two wan configured and working fine. My problem is because some sites like Banks block the access when the connection change the IP WAN1 to IP WAN2. How I can configure the router to use any wan, but stay  on that wan, without change until another connection ?

Thanks

are there any particular issues or weaknesses you find when auditing companies anti-virus defence deployment/maintenance installed on servers/desktops etc. Please give some background on common errors/mis-configurations/issues to look out for in a review.

We’re using a SonicWall TZ-215 firewall.  Our LAN X0 port is setup as 192.168.0.1—254, with 192.168.0.2 setup as the gateway, 255.255.255.0 as the subnet.  

We’re getting VoIP phones, and the vendor is setting them up with static addresses between 192.168.1.100—200, subnet 255.255.255.0.  How do I configure the SonicWall to get the phones to access the 192.168.0.2 gateway?  (X3—X6 interfaces are unused on the SonicWall, if needed for the solution)

What's the best way to check the current bandwidth utilization in the office?  We have have Internet-> PAN fw->juniper switches->users.  Is it something built into those devices to check that or install some app on the top of that, or...
 
I want to look at what bandwidth utilization I have now and estimate it's max growth based on new headcount / office expansion.

Hello
Currently we have TMG as web proxy and websense as web filtering
We are going to replace TMG with Bluecoat SG Appliance.

Hence I need to know which design is considered as best in terms of secure and efficiency.

We have 1500 users.

Any help would be appreciated.
