Dear Experts,

I've completed my basic home network setup by configuring VLAN with router and switch. I was able to make it happen with ubiquiti Edgerouter and cisco Sg200 switch. I setup the Vlan10, 20, and 30. I am able to communicate between the vlan as well. I will later setup the rules in the router to restrict the access between the vlans. The funny thing is that I've configured my router under 192.168.10.1 and my switch under 192.168.10.2. I was able to access my router via the IP but I cannot see my switch. My computer is on 192.168.10.100. The setting of the switch port that my computer connected to has this setting:
 switchport #20:
 vlan 10
switch port mode: access, untagged (excluded from other vlan)

I can set my PC's IPv4 configuration to auto which I will be assigned to one of the IP under 192.168.10.x/24 I can see other devices on the same network and have the access to internet as well. I just can't access the switch portal on IP 192.168.10.2 and I cannot ping it.

If I connect to a different switch port with a different setting like this:
switchport: #24:
vlan 1 (default vlan)
switch port mode: trunk, untagged (excluded from other vlan)

I will need to configure my PC's IP in Windows10 to IP: 192.168.10.100, submask 255.255.255.0, gateway: 192.168.10.1 then I will be able to access the switch portal at 192.168.10.2. If I don't manually configure my window's IP then I will not be assigned into an IP under 192.168.10.0/24 range.  Under this …

Dear experts,

I have a network with Servers and end points that need to communicate via IP and TCP ports. I would like to add these IPs to our SolarWinds management, can I also monitor TCP specific ports connection.

On the network or server how can I find how many TCP ports are established between the server and clients.

Any Feedback will be appreciated.

Hello Experts,

I have issue with an external client, he is using
a laptop with Cisco anyconnect vpn client and he would
usually connect to the vpn and would be able to browse the
internet and also access internal resources, shares and sites.

Today he connected from home and he was not able to browse anything,
I checked his laptop remotely and I was not able to ping google or resolve
any DNS names. To get him going I gave him default gateway IP in his VPN connection
but I am not suppose to do that.

My quest is why when he connects to vpN, the DNS stops.
I tried to replicate the issue using my hotspot and on my laptop
but i did not get the same symptons, my VPN does not give me GATEWAY ip and I
am able to browse plus access the internal resource.

I am certain this issue is local to his internet connection
at home.Please do let me know if anyone has any suggestions.

Thanks,

I'm trying to limit SSH access to a Cisco ASR 9k switch running IOS XR Software, Version 6.2.3

From this document https://tools.cisco.com/security/center/resources/increase_security_ios_xr_devices.html#18 ..I tried to limit the ability to SSH to the management IP of the switch.
But after adding removing allow ssh and replacing it with allow SSH peer/address ipv4 10.3.7.27 - I am still able to ssh from any address at all. What am I missing?

control-plane

  out-of-band
   vrf management

    allow SSH peer
     address ipv4 10.3.7.27

ipv4 virtual address vrf management 172.18.21.11/24

Hello Experts,

I have 200 MEG internet connection and recently due to business demands and changes they want to transmit in and out close to 1000 packets each will be 1 MB = 6000 MB worth of transaction over 8 hours daily, I want to know how to put this in a calculator to check if I will have enough bandwidth.

Can any of the experts recommend how to check this type of demand against the bandwidth and determine utilization consumption/

Thank you,

Experts!  Has anyone had any experience with the Ubiquity Unifi SDN product.  I have some aged firewalls and switches but have a few Unifi APs.  I've used Meraki in the past but get's quite pricey.  How does the UniFi Firewall, Switch, AP and network controller solution add up?  How is the Intrusion Prevention/Detection system?  I really like the ability to centrally manage and define my network.  We are an educational institution and have 2 primary and 2 satellite campuses.

I am currently using Ninja but am in the middle of a 30-day trial with N-Able. N-Able looks impressive but 30-days isn't really long enough to learn about the issues and problems. Does anyone currently use N-Able and can you give me an honest evaluation of it?

Hi guys

There are moments when people in a particular area of the office have connectivity issues from their local PC's to the actual servers. They will say that connecting from their local machines to the server is taking a while.

I know it may not be necessary, but I would like to know if tomorrow I wanted to show people how you can measure network traffic or even connectivity problems at different points on the network, I wanted to be able to showcase it.

I was wondering whether there are ways of testing each segment of our network to see whether there are any red flags that come up. For example, how would I measure if there is a physical connectivity issue between the floor port their PC's are plugged into and the port on the switch? How about from the switch they are plugged in to, to the server? If so, then can you explain, literally, how would you go about doing this?

Thank you for helping

On two separate projects in two separate companies I have become aware of an issue where AD information from a long time ago, seems to revert back into AD.  In case A, a DC had been removed several months prior, and then Bam!   it looked like there references in AD to the "flying dutchman" AD server.  In case b, the event seems to revolve around a switch reboot.   In this case AD information from YEARS ago returned (We think the information coincides to the point when the systems were imaged and first brought into the domain (like 6 years ago))  I did note that one of the DC was not responding to dns queries via nslookup, and workstations on a specific subnet seemed to revert from DHCP subnet IP to a 169 address.  Immediately after the event rebooting the workstations still left the system with the 169 addresses.  The switches involved are Cisco switches and the subnet has an IP helper for the interface.


I don't have specifics on what happened, I am just trying to understand what causes an event like this.

I have an idea to create a separate DNS zone for the wifi network.  Segregation would help with administration and management.
 Does anyone do that already and does it help?  Has any benefits?
My concern is the lag maybe longer when moving laptops from wired to wifi network I think. Any other concerns?
 Please advice.  Thank you!

I appreciate the feedback i've received thus far. I've demoed multiple products, and have narrowed down the list to about 6 products. What would you recommend, based on personal experience, from the following:
SolarWinds RMM
Atera
Pulseway
Kaseya
NinjaRmm
LogMeIn Central

My core requirements include: remote access (unattended), anti-virus, remote script execution, patch management, asset management, reporting, and performance monitoring

Thanks in advance!

Hi,

I have a Cisco SG200 Switch and a Sonicwall TZ400.  I need to isolate 9 networks from each other. Each network has its own DHCP.

Here's my config:

VLAN1 192.168.2.0
VLAN2 192.168.1.0
VLAN10 192.168.10.0
VLAN20 192.168.20.0
VLAN30 192.168.30.0
VLAN40 192.168.40.0
VLAN50 192.168.50.0
VLAN60 192.168.60.0
VLAN70 192.168.70.0

Sonicwall interfaces
Sonicwall DHCP
 I've read and followed the instructions on setting up VLAN on the CG200 but maybe I'm missing something or maybe I'm missing that magical matching combination of correct settings and a router/switch reboot at the right time.  I've checked with Sonicwall and they say that I have everything configured right on the TZ400.  They say that my SG200 is not properly tagging the traffic going to the Sonicwall is not seeing the tag so it's not going to the proper VLAN.  Here's a screenshot of my Port VLAN Membership:

cg200 port vlan membership
I've spent hours trying to get this figured out and it feels like I've hit a wall now.  Any help is greatly appreciated!

Hi,

I am trying to setup VSS and VLAN in Cisco 6807. I followed the steps in the link

https://www.youtube.com/watch?v=LVYcdgaLeeQ

I have questions (Any help will be appreciated)
- This steps must be done in one of the switches. Is that correct?
- I have 9300 switches that need to be connected to 6807 switch. I must connect two physical fiber connection one from each switch  (6807) to (9300 switches). Is that correct?
- I want to configure 10 VLAN's (192.168.0.0, 192.168.1.0,......192.168.10.0) with VTP domain in the (6807) switch ( I will need to assign IP address for each VLAN and create Management VLAN). How I can do that?
- I will change all the port that connect the 9300 and 6807 switch to trunk mode and use encapsulation Dot1Q.
- DHCP server (Multi scopes) address is 192.168.0.100. So, I will need to configure IP helper address under each VLAN.
- Port 10 of Cisco (6807)  in switch 1 are connected inner interface of ASA [IP address 192.168.0.1 and outer (public IP address 85.X.X.X)]. I need to be able to connect all VLAN's to be able to connect to internet and can see each other. How I can configure that?


Switch6807-1(config)#switch virtual domain 6
Switch6807-1(config-vs-domain)# switch 1
Switch6807-1(config-vs-domain)# switch 1 priority 110
Switch6807-1(config-vs-domain)# switch 2 priority 100
Switch6807-1(config)# interface port-channel 1
Switch6807-1(config-if)# no shutdown
Switch6807-1(config-if)# description VSL to switch 2

Hello Experts,
I have a computer named "Toshi-A"  (Win 7)
its local IP: 192.168.0.14
all its drives are shared with "everyone" "full privileges"

when I try to access from other computers (WIN10)
using
\\Toshi-A\c    ----- I get 0X80070035 Path not found

But when I use
\\192.168.0.14\c
Works just fine.

What do I do to fix this?

We have an internal application, whereby users are required to reset their passwords every 90 days. The application has its own security & accounts, and does not integrate with our AD domain in any way. The system itself stores fairly personal client records. If a user does not access the application in a period of time, the administrators do not seem very effective in disabling the users account which is what should happen (they are expected to manually review all active accounts every 8 weeks and disable any stale accounts, and query them with their line manager to determine if access is still appropriate or not), this what should happen – but a recent audit has identified this does not appear to be the case or working effectively.  

The application itself does not work in the same way as say Active Directory, as if a users password has expired (every 90 days is the current setting), the application does not simply prompt them to set a new password and then access can be achieved again, the administrator would have to reset the users password before access could be achieved. The admins are of the view that this is sufficient, e.g. if they have a list of 10 accounts who have not logged into the system in over 365 days, it doesn't really matter that they haven't disabled their accounts, as they cannot gain access to the data as their passwords will have expired. I am not overly comfortable with this approach, but I am struggling to find any real reasoning to counter their …

Hi,

I am looking for a backup and restore (Disaster recovery ) solution for my servers. I have 2 cluster SQL servers, application server, and 4 domain servers. I found many solutions like solar wind, Zetta , MozyPro, CrashPlan...etc. My data size almost 2T. I really need help with this. Can you help me or suggest good backup solution with affordable price?

Thanks

First Question.

Ages ago I had two switches given to me: a Cisco 2950 and a 3Com SuperStack 3 3C16592B.  And they've been sitting tossed aside for a long time.  I'm now in the process of decluttering and one has to go.  Which one and why?

Second Question

Now I'm a total noobie when it comes to these switches.  If I remove all passwords and take these machines back to factory or default they can be used as dumb switches, that is, I can plug anything into them and they'll function perfectly normally, getting their IP addresses from my home router?  I've just started playing with the Cisco and examining how it has been configured (shudder VLANs everywhere etc etc etc) so I'd like something simple to start off with before I venture into unknown areas.
