Hi - currently we have several Cisco 2960-24PC-S 10/100 POE switches, that we are going to be replacing with Cisco Catalyst 2960X-24PD-L POE switches, because of age and the need for the gigabit connection. My question is (my limited Cisco knowledge) that we have SFP Modules that we cant seem to figure out the model #. In the inventory on the switch it shows up next to the Description as "1000BaseSX SFP", and the serial number below it. Does anyone know if these are compatible with the 2960X switches?
I have few offices that I need to support, I always assist remotely the business users.
Was wondering if there is a KVM switch that connects to the internet, and then I can plug it to a computer via USB and VGA so I can control the machine remotely, even via the bios. Kinda like HO iLO.

Any recommendations ?
Hello Experts,

I am trying to design WLAN solution in open facility, due to cabling\connectivity issue following proposal is provided:

Assume a lager circular facility and outdoor APs (around 120 aps) need to be installed at peripheral.

 we don't have POE option and to install multiple switches thus I need to validate following solution will work?

1.  run fiber across the periphery.
2. connect fiber end to Switch and trunk it with vlan 10, define dhcp scope for vlan 10
3. splice fiber across the periphery at AP connectivity point.
4. use fiber to Ethernet converters.
5. we can use external power injectors.

would appreciate your help in validation.

Hi ,

we have subsidiary company with around 150 Users . it is linked to us (HO ) over IPVPN (1 MB)  and services getted from Us are :

1- CISCO IP telephone ( currently around 75 Users)
2- ERP ( about 50 USers)

thier existign Setup :

1- Domain COntroller ( seprate totally from us ) + Antivirus server ( 1 physical box)
2-finance system
3-Backup Server
4-Sonicwall NSA2600
7-Router for IPVPN

the managment is thinking to host the setup for the subsidary company so my questions are:

1- how I can do the proper sizing for the link ? so i ensure the users are not feeling slowness
2-what equipment should i move from there and what i should not ? best desing fro myour experince
3- how the internet should be provided to thier users ? from us or locally ?
4- what are the adv and disadvanage for such plan? should we recommend this plan or let them continue as they are
5- risks?
6- what are the pre requisits needed in the HO Data Center for hosting those equipment
It seems that the documentation about IPsec/IKE setup on an SRX to Azure s2s VPN is conflicting.  There are 3 pain points:

1.  Can IPsec/IKE be used on a policy-based VPN for Azure? It seems that Azure is clear about "no" but the suggested Azure config includes IPsec & IKE config
2.  Which IKE version is best for SRX to Azure - v1 or v2, when using Policy Based or Route-Based VPN? (see attachment)
3.  If a trust sec zone (internal interf.) and an unstrust sec. zone (exter. interf.) already exists, how can I add interfaces that are in one of those zones already to a new "Internal & Internet Zone" for the Azure VPN Tunnel as documentation suggests?  I receive an SRX error about adding interfaces to multiple zones prohibited and if using PB VPN there is no st0.x to that config and/or I don't understand how to utilize or place the traditional interface under the st0.x iface.

Hello- I am in desperate need of help. I implemented a Cisco SG200 Smart Switch. There are only 24 gigabit ports, so I attached a 24 port unmanaged Cisco switch to it. However, most (not all) computer and VOIP phones are not able to obtain IP addresses from the UTM connected directly to the Smart Switch. The LAN adapter on the computers say "Unidentified network".

I have been researching this for 6 hours and I can't figure out why these devices are able to get an IP address.

Thank you.

Good afternoon All

I am looking for community help to get me started on a Dell PowerConnect X4012 (2switch stack) configuration for 3 Dell XC servers with Nutanix on them.  I also have a TOR switch stack of 2 x Dell 3024 switches.  I have found in the past best practice documents for configuring Dell kit for VMware but I can't find anything conclusive for the above.

What vlans am I going to require for Nutanix AHV HCI?  

Any help gratefully received.

Hi all, looking for some assistance with a SQL cluster issue, would appreciate any assistance available.
xxxSQL07 is the name of the SQL cluster (windows cluster name xxxSQLCLU02) made up of two nodes; xxxsql03 and xxxsql04.
All works, able to connect using SQL studio using Windows Authentication (tried multiple accounts, including the service account that all SQL runs on on this domain).
The problem has presented itself as we've recently created a reporting server (xxxrpt02). The local publication has been configured linking to the only database on xxxSQL07 and wizard completed with no errors. From SQL studio on xxxRPT02, when trying to add a local subscription I receive the error message, "The target principle name is incorrect. Cannot generate SSPI context. (Microsoft SQL Server)". I've tested the reporting server by connecting to a local subscription on another SQL cluster which works, I also tested the faulty domain cluster from the other working reporting server and received the same error.
This error occurs whenever I try to connect SQL studio to this SQL cluster. I've also tried connecting to the name of the windows cluster but that didn't work.
In an attempt to fix this issue I took the xxxSQLCLU02 offline from failover manager and performed a repair in an attempt to get this connecting in to Active Directory correctly.
The SQL cluster name is pinging and the IP is resolving when pinging -a.

I've done some digging around and am erring toward this issue being…
Hi we have a thousand of switches in the network. and Orion has been configured on each switches. Now we have a few of commands that need to be implemented on each of switches. How can we add these commands to each switches via Orion? Or you can send me a link for this issue. Thank you
A few years back I had SolarWinds Real-Time NetFlow Analyzer working with my Cisco 3750x switch. Recently we had some suspicious traffic so I installed a new version of the software on a Win 10 machine. I can connect through the software to my switch, I can see all of the interfaces but none of them show NetFlow enabled. When I click on the interface I want to monitor then click "Start Flow Capture" I get a 'NetFlow is not detected on the selected interface'.

How do I get this port configured correctly to capture NetFlow data?

Additional Facts:
IOS version 15.0(2)SE6

Config on switch:
int gig <port to be monitored>
ip flow ingress
ip flow egress

ip flow-export source <port to be monitored>
ip flow-export version 5
ip flow-export destination <IP of my Win 10 machine> 2055

Open in new window

Per this thread- 
I tried to run the ip nbar protocol-discovery and the ip route-cache flow on the port to be monitored. Neither of those commands were accepted on that port.

Any help is appreciated.

I've had users on other forums attempt to help me by pointing me to towards flexible netflow configurations that use the command ip flow monitor <name of monitor> input applied to the interface they want to monitor. My switch does not allow flexible netflow to be applied to non-service module ports. What I'm trying to monitor are the standard gigabit interfaces.

The netflow commands I can apply to those standard interfaces are those listed above: ip flow ingress and ip flow egress. How do I get netflow analysis that way?
Hello People,

This is kinda engineering question. Its about the hardware and power knowledge.

I have a Ubiquiti Loco M5 which is connected to a public access point (No encryption required)
Everything is working, except random disconnection which I'm pretty sure its because of the range. Its connected with -80
I am 1 Km away from the AP - but the signal is poor because Loco doesnt have enough power!!

How can I boost the receiving on Loco M5. I mean HARDWARE. not configuration within the Loco which I tried EVERYTHING.

I need something to add to the device in order to make it more powerful for receiving signal! like changing the adaptor? or PoE? I've heard if I changed the power supply, it'll help. But I have no idea about the power and what should I buy.

Any ideas?

This electronics manufacturing company will be building a 2 storey, 100K square foot facility.
The mail floor - all the manufacturing machines, computers and servers running manufacturing software
The 2nd floor - the main server (Microsoft SBS), SharePoint Server, LOB software servers, and computers used by office staff and engineers.  

They have less than 200 employees, over 120 computers, 5 physical servers, some VoIP phones. They are all on the same network. Currently, there are only 28 IP free addresses available from the DHCP server (Microsoft SBS)

Here are my thoughts about the network in the new building
1. Install stackable switches in each floor's server room. Connect the two groups of switches via a long high speed trunk cable running thru the floor.
I think this will keep the network traffic on the main floor in the main floor network from the 2nd floor network, which optimize the bandwidth.
Currently, they are using D-Link DGS-1510-52 switches, which have been quite reliable, except that i had to power cycle one of them twice in the past years, and their firmware are a bit buggy.

Is it worth to deploy Cisco switches which are more expensive and cause a learning curve? Is there such a long high speed trunk cable at all?

2. Separate computer network, VoIP phone network and Security/Access Control network with 3 different networks.
This will release quite some IP addresses from the DHCP …
Dear Experts, I got this problem with my Cisco router when issue command "show ip flow top talker". What is a Null interface here?

Many thanks!
I have an old Dell PowerEdge 2800 domain controller sitting in my office that is collecting dust.  I was thinking about converting it into a server that we can use to backup the hard drives of the individual workstations in my office.  It has a boatload of hard drive space in a hardware RAID array, which I believe is large enough to hold the workstations.  There are 9 workstations that would need to attach to the server.  Right now, it has MS Server 2003 installed on it, but not much else.   Our workstations are a mix of Windows 7, Windows 10, and I think we have one Windows 8 laptop.  On a suggestion from a guy who does some IT for us now and then, I was thinking about reformatting the server with Linux to do this job, but I don't know if that is the best way to go about it because I haven't used Linux since college.  

My question is this:  Is there a software solution available that will allow us to automatically backup our workstations to an old server that is relatively simple to install and maintain?  We have a small business and don't have dedicated IT staff, so I will probably have to do this myself and I don't want to have to learn something really complicated.
 We don't need the domain server anymore and I am willing to install a different operating system if necessary.  Thanks for any suggestions.  If the suggestion is to go with another operating system, please let me know the build or the version.  Thanks.
Hi Guys,

 I am trying to use hyper-v extended port acl's as a basic form of firewalling for vms on hyper-v server 2016

My goal is simply to limit incoming connections while generally allowing outgoing traffic (and return traffic).

In essence we are allowing incoming http(s) and dns replies. All outgoing tcp traffic is marked as stateful.

We use the following acl's (cleaned up slightly for readability)
Add-VMNetworkAdapterExtendedAcl -VMName "web" -Action "Deny" -Direction "Inbound" -Weight 20
Add-VMNetworkAdapterExtendedAcl -VMName "web" -Action "Allow" -Direction "Inbound" -Weight 30 -Protocol 1
Add-VMNetworkAdapterExtendedAcl -VMName "web" -Action "Allow" -Direction "Inbound" -LocalPort 80  -Protocol "TCP" -Weight 60
Add-VMNetworkAdapterExtendedAcl -VMName "web" -Action "Allow" -Direction "Inbound" -LocalPort 443  -Protocol "TCP" -Weight 70
Add-VMNetworkAdapterExtendedAcl -VMName "web" -Action "Allow" -Direction "Inbound" -RemoteIPAddress "" -RemotePort "53" -Weight 130
Add-VMNetworkAdapterExtendedAcl -VMName "web" -Action "Allow" -Direction "Outbound" -Protocol "TCP" -Stateful $True -Weight 150

Open in new window

The issue is as soon as the last stateful entry is added significant latency is observed to the point of things becoming useless.

In the cisco switch acl world you would simply look for the established flag for the packet.

Is there a way we can achieve the same here without incurring these severe performance penalties? Am I doing it completely wrong?

thanks for any insight.
Polycom Soundstation 6000 not saving the Provisioning user information.  It saves the URL, but when you try to save the username and password, it "says" saved, but when you reboot or refresh the page, the credentials revert back tot the default one.  I also tried to enter it through the display (not the web UI) and same results.

I also tried to update the firmware, tried almost all of them and still same results.  Anyone have any other ideas?
