Hi Experts

We had one of our 3750's hardware fail, will not power on. Were currently purchased a new 3750 to replace. Would like some general guidelines on the steps to do so. the most important we want the vlan information to come across.
Do we backup the config on an existing switch and apply it on the new one? - We tried and received a lot of errors
Do we apply the vlan and other port information (below is our existing) to match what we already have.
How do we place the switch back in the stack, unpowered and connect all the stacking cables and then power it on?
What Impact will that have on the stack, will it power down?
What will and will not come across after we add the switch to the stack, do we need to set a password on the new switch, I know after you add the switch the master takes over and it applies some information - firmware.

The switches in the stack has a lower SW Version than the new switch being added will it be downgraded automatically or something we have to do manually.  (sw version of the switches in stack 12.2(25) SEB4 \ New Switch 12.2(55)SB


interface FastEthernet1/0/12
 switchport access vlan 10
 switchport voice vlan 20
 srr-queue bandwidth share 10 10 60 20
 srr-queue bandwidth shape  10  0  0  0

Hi,
Please do you have an answer for my situation?

Print Server = Windows Server 2012 R2
Client Machines = Windows 7

I have already added our printer (Samsung) and I am deploying through GPO which works fine. However, when I have added the Fax Utiliy (Which sets up as a seperate device) this does not deploy. I tried to add the Fax Device manually on a client machine and I am prompted to install drivers. I click "install" and it fails with the error 0x000003e3. I believe this is why the GPO is unable to deploy the fax service.

The fax service is on the same IP as the printer object so I cannot add it using LPT1 with IP address as this is in use by the Printer function. I have to create a Samsung Network PC Fax port.
How can I configure this so that users are not prompted to install drivers that then fails with the error? I believe I will then be able to deploy through GPO to my users.

Many thanks
Pete

Recently we added a new TPG IPVPN Connection (MPLS Network with Hosted Firewall) to eth2 on our watchguard but cant get it to work properly (see attached picture)

For some reason i cannot ping any Sydney LAN IP Addresses (on 10.50.2.0/24 network) from QLD Office to Sydney Office.

What do i need to enable / configure on the wathguard so i can ping internal lan addresses from qld office ?

QLD Office LAN is on 10.4.26.0/24 network.
Sydney office LAN is on 10.50.2.0/24 network

From QLD office I can ping 210.10.228.14,210.10.228.13, 10.252.0.6, 10.252.0.5 OK, but if I try to ping the Watchguard LAN IP Address 10.50.2.90 or another device in the same Sydney network from QLD Office it times out. Any ideas ???

Sydney Office Watchguard Configuration is as follows:

I have 3 interfaces setup on my Watchguard x750e firewall with following parameters:

Eth0: IP: 210.10.228.14 (External) - This is connected to a ISP Managed Cisco 1900 Series Router. This is a routed subnet services TPG NBN Conneciton.
Gateway: 210.10.228.13
NetMask:255.255.255.252

Eth1: IP: 10.50.2.90 (Trusted)
Netmask: 255.255.255.0

Eth2: IP: 10.252.0.6 (External) - This is connected to a TPG NTU and is a IPVPN Connection. This also requires RIPv2 and has dynamic routing setup.
Gateway: 10.252.0.5
Netmask: 255.255.255.252
Dynamic Routing Configuration:

I have a Supermicro X9DR3-LN4F+ board with on onboard Intel i350 NIC adapter. No matter what OS (W10, Ubuntu, CentOS) or BIOS settings I try I cannot recognize the NICs. What is extremely odd is the LINK LEDs blink orange randomly, and the activity LEDs never light up.

Any ideas or input would be appreciated.

PS - The PCI-e slots and everything else works fine as I have 2 Adaptec RAID cards and 2 Intel Quad Port NIC cards that work fine on my install of XenServer, so I am baffled by this one.

I just purchased a used Calix E7-2 chassis with a GPON-4 card. I was able to connect to the MGT-4 RJ45 port on the Fan unit via https://192.168.1.1 and get the Calix login screen to come up. Looked around and found a number of potential default logins (username/password):

admin / 1234
admin / admin
root / root
root / cmsroot
support / support

None of these work, keep getting authentication failure. I read somewhere you can reset the database to defaults (don't know if this includes logins) by swapping the cards in the two slots. I've done that but still none of those logins worked.

If anyone has ideas I'd love to hear 'em.

Thanks

I have a security camera project that requires a run of about 1000FT for a few cameras.

I know Cat5/6 are not options due to the 300ft limitation.  I guess I could use POE switches at 300/600/900 ft as repeaters but that doesn't sound like a viable solution.

any ideas?

Hello,

I have a famous blue cisco serial cable and ive cut off the rj45 head a bunch of times trying to wire up based on the answer of
'https://www.experts-exchange.com/questions/23554372/Convert-Cisco-DB9-RJ45-console-cable-to-a-null-modem-DB9-RJ45-cable.html' However, it didn't work for me.

The color order of my wires are with the retaining clip facing the floor:

1: Grey
2: Orange
3: Black
4: Red
5: Green
6: Yellow
7: Blue
8: Brown

So please tell me what order to place the wires in so i can setup this DSR8035. The password is not known otherwise id just set it up via webgui. I was however able to change the ip address via vga and usb mouse/keyboard. ive tried the default Admin and admin with password and no password.

Thanks!

-Tom

My client has 3 physical locations, all just switched over to Charter Spectrum Business running on an Engenius ESR600 wireless router.  2 locations have no problems ever.  The third location has 6 computers, of which 5 will lockup using the AMS360 website.  The computers have never frozen except during AMS360.  The computers never once froze before switching to Charter Spectrum.  The 6th computer is the only laptop in the office and doesn't use AMS360 much if ever.  So I began testing power to computer stations, but no power issues could be found at the two highest occurrence PCs.  To make things worse, the problem never effects two computers at the same time.  The software can run in IE or Chrome, and the problem are the same on both browsers.  Most of the time, the browser is not responding and never recovers, but you can open another instance of the browser and work just fine.  On a slightly more rare occasion, the user will report one of the AMS360 tabs will go gray (Not responding), and when the go to another tab and work there for a short time it may lock up (No mouse, keyboard or any input).  They have waited an hour to see if anything will change, which it doesn't.  I don't really know the actual frozen vs not responding broswer %.  I have seen first hand an unresponsive PC at this client and the browser not responding.  All computers are Windows 7 SP1 64-bit.  They are a mix of Lenovo ThinkCentre and Dell Optiplex computers.  I have installed all updates and drivers …

Hello,
I have a Cisco ASA 5506 which is stuck in rommon mode.

I have it as a test device, I have the image file: asa962-lfbff-k8.SPA available on a USB disk, which is connected to ASA.
When i go into the device I see the USB as Disk1.
My question is how to copy the image to Disk0 & set it up for boot without TFTP, SMB or FTP?
or even if it's possible?

Thanks

I have a computer at 10.100.10.xxx.  On the same physical LAN there is a printer at 192.168.0.x

The computer can ping the printer.

There is a print driver installed (Windows 7).  When I print a test page, the page leaves the queue after a few seconds. Yet nothing ever comes out of the printer.  Other computers on the printer's subnet print without issue.

Any idea if I'm dealing with a networking/subnet/mask issue, or perhaps something else?

Thanks.

Hello All
Our core network consists of four Juniper SRX 240h security appliances. They are connected in a ring and use OSPF as the internal routing protocol. On core facing interfaces and ports we use to connect access switches, we have discovered the ‘FIFO errors’ field is incrementing on almost all the interfaces on all four devices. FIFO transmit errors are all 0 but the receive errors value is steadily rising.

After some research online it appears that if the value is not 0, there is most likely an issue with the PIC on the device. As this is happening on all devices it seems unlikely to be a hardware failure but I’m not ruling it out.

Statement from the Juniper website:

•      “FIFO errors—Number of FIFO errors in the receive direction that are reported by the ASIC on the PIC. If this value is ever nonzero, the PIC is probably malfunctioning.”

I’ve also read it is a possible auto negotiation problem on the interfaces. We can see the devices are negotiating the correct duplex and speed settings. On one of the links in the ring, there is no FIFO errors at all on the interface. Also it has auto negotiation setup suggesting to me the problem must be somewhere else.

Example MAC stats output:
  MAC statistics:                      Receive         Transmit
    Total octets                   23084979779      15333372494
    Total packets                     29358714         26257095

Hi
 
I'd like to set up a network within VMware® Workstation 12 Pro that is comprised of the following to help with my IDS investigation
 
1 x Kali (attack)  - This my attack VM and has full internet access via my PC Hosting VMWare
1 x Ubuntu (IDS) - This VM has an IDS on it to inspect traffic between the  'attack' VM  and the target VM's
2 x Target (Windows + Ubuntu) - These are the Target VM's, I'd like the traffic from these to always go *through* IDS

Essentially I want to be able to see all traffic from / to the Targets through the Ubuntu (IDS) machine and ensure the Target machines' traffic is routed through the Ubuntu (IDS)
 
I've got the VM's running individually within Workstation, but I cannot work out how set the network connectivity correctly, I've tried NAT, Host etc. - but I can't seem to get the right combination.
 
Any help would be really appreciated.
 
Thanks

Hi,

I am looking for a inexpensive way to connect a cisco switch in a lab and not have a huge electric bill like a Cisco 2950 or 3560. It would be nice if I can connect a SOHO 24 port device and run a CISCO IOS on top of that. I do not think thats possible but the SOHO switch would use less power. Any alternatives out there.
