5 and 8 port switch

I heard that Linksys switches will pass eapol traffic to the access layer of the etn switch with no problem. Other brand of switches give an error and the switch port will get blocked.Could you tell me which model number to order of your switches for 5 or 8 port switchesthat enable eapol traffic to pass through them with no problem?

This is an layer 3 protocol and I think should work with any non-managed switch shouldn't it?
Please remember to Kudo those that help you.

8 port or 16 port switch

I am using 8 port and 16 port switches in my organization. Is there any way to block the ports since there is no IOS that comes in these switches?

The SD216 is an unmanaged switch, so there's no way to block the ports from
software.
What you could possibly do:
block the ports physically: stuff something in the unused ports, like vax or something. This will void your warranty, though.
if you have a managed switch between this SD216 and the rest of the network, assign static MAC addresses on that switch and disable dynamic learning.
Cheers,
Tamas

Front end and console ports are down for switch WS-C3750X-48PF-S

We have a switch WS-C3750X-48PF-S in the stack and front end and console ports stopped working and are down.
I have tried to replug power cable but this didn't help, please let me know if I could replug stack power for this switch without outage of other switches in the stack, since switches are connected into the ring
Please let me know what might be the possible root cause

Hello,
There is a problem with the stacking connection between switch 4 and 2. Can you try replacing the stacking cable between these switches?

I'm using windows 7, trying to download pictures from my canon 5d mark 2, but when I click import, the camera does not appear. I've tried changing USB ports, switching the camera on and off, trying a different USB cord, tried a different camera, but nothing. Please help! This problem only started a few days ago on lightroom 3.6, upgraded to 5.5, but still not working. Thanks.

Can you see the Canon EOS camera and image files using Windows Explorer? If not disconnect the camera, close all applications' shutdown Windows, and TURN OFF the power to your system and ALL connected devices. Disconnect all phones, iPads, and any other USB devices and restart your system.
Retry Windows Explorer and see if your camera is showing. If so try LR import again.

Cisco 5 port and 8 port gigabit unmanaged switches

I am looking for 5 port and 8 port gigabit unmanaged switches in Cisco. Please provide the BoM for the same. As per my understanding the following switches can suffice the requirement (SG100D-05 and SG100D-080) however I am not sure about the DC power, whether they can be used in normal AC environments.

The SG100D-05 and SG100D-08 are too small and their power requirements are too low to justify building an AC power supply into them like the larger SGx00 switches have, so they are wired to accept DC power and use an external power adapter (included) for connection to an AC environment.
There are really no optional components to these devices, so the BOM would be as follows:
5-port SG100D swich: SG100D-05
8-port SG100D swich: SG100D-08

Configuring - Cisco 2921 with Switch Module/POE PS and 3750-x 24 port switch

This is what I have
- Cisco 2921 router
         with SM-ES2-24-P switch module and
                 POE power supply
-Cisco 3750x- 24 port Switch
I have port G1/0 (which connects to 24p Switch Module port g0/26 logically) configured with 3 sub interfaces (management, User and VOIP)
I want to connect 3750x to G0/1 on 2921 via fiber GBIC but want to use same three VLANs
I can not daisy chain 3750x via the switch module because it does not have fiber port.
I do not want to create another routed (g0/1) interface because I want to keep Users on both switches on the same subnet without further splitting the subnet in two.
I hope I am not making this confusing.
How can I bridge g1/0 and g0/1 so I can pass vlan traffic between two switches?
Second problem i have is ...
I have a VOIP connected to switch module (SM) and it is not getting any power.
I went in to all the interfaces on SM and issued power inline auto command
On the SM (sh power inline) - available is 0.0(w)
on the 2921 (sh power inline)
   - power supply status is good,
   - maximun power available is 280.
   - interface G1/0( which connects to SM)
      *device is unknown
      * powered off
     * allocated 0.0 watts.
I already tried resetting SM
Is there any other command I need to issue?
thanks for your help.

I'm having a similar issue. I can get trunked connectivity between the switch module and the router if I put the IP address on the router sub interface, but not if I put it on a VLAN interface. I was hoping to have it on a VLAN sub interface on the router so I could use Gig0/1 and Gig0/2 to connect other switches and have them on the same VLANs. I'm using Gig1/0 on the router side and Gig0/51 on the switch side (48-port module).
Any help? Am I on the wrong track altogether?

Redundancy management IP and Redundancy port IP unreachable issue

Hi, all
I got one interesting issue with wireless 5508 controller. we have ordered two WLCs, one is air5508-12-k9, Anther one is air5508-HA-k9.
Now, we are going to form HA mode and HA box will become standby mode. One issue we are seeing now. after configuring redundancy management IP and Redundancy port IP to both WLCs. primary WLC are working well that we can ping it's all of IPs successfully, however standby WLC are not working well. even it can't ping itself. management IP has no problem.
Problem is only for redundancy management IP and redundancy Port IP. One interesting thing is our switch can't learn redundancy port's MAC address even it's connecting and interface shows UP. Primary has no this issue.
Has anyone have the same issue before or appreciate any suggestions and inputs.

Parallel port switcher

Hi all,
I have attached a parallel port switcher that I downloaded but I keep getting the error "manager call not supported" as attached.
How can I run/ use the attached vi? I have Labview 7 and Labview 8.5 installed, in my Windows XP and Windows 2000.

Hi all,
I've soldered 3 LEDs to pin 2, pin 6 and pin 9 and pin 25 to ground. I need to control the on off of the 3 pins through Labview. I've modified an example I found in Labview as attached but there are things that I don't understand:
1. Why is it when I clicked both LED 18 and 22 on Labview, all my 3 LED on breadboard (connectted to pin 2,6,9) turned on?
2. Why is the "register write value" in Labview consists of 32 LEDs? How can I change it to may be 8 or 3 LED?
3. If I change the "register write value" to constant, what value or number should I insert to on/ off my LED?
Please advice.

Unable to fully form trunks between 3850 and 4503-E switches

Hi all,
This last weekend I tried to replace a stack of 3750G's with a stack of new 3850's.
The stack of switches has 2 fibre uplinks to the core switches (4503-E).
It didn't go well, and I had to revert the project.
The stack was all pre-configured in the workshop but could not be tested on the live LAN. When I connected it , I first connected up 1 of the 2 uplinks. The link went to UP status, and I could see the remote core switch via CDP, but it would not learn the VLANs (VTP was setup correctly), and looking at the port on the switch, it flashed green, went solid green, then flashed amber slowly. This cycled continuously, whilst the link status remained up and no errors were logged by either switch.
I debugged spanning-tree but nothing stood out. I tried a replacement SFP, and a different slot but no difference.
I re-connected one of the old 3750's and immediately the link came up stable, and everything was fine.
I then erased the config on the new stack, and simply set the fibre port as trunk, with udld enabled (matching the remote end) (neither switch supports ISL, so the trunk is dot1q). The same issue persisted.
Last night I spent a few hours in the office investigating. I grabbed a spare 3560G from the store, configured a fibre port as a trunk, and connected this to the 3850's, and this worked fine. I then provisioned a new fibre port on the core 4503-E and connected this up using brand new fibre tails, but had exactly the same issues as described above.
The switches were running cat3k_caa-iosd-universalk9.SPA.150-1.EX3, and I have upgraded them to cat3k_caa-universalk9.SPA.03.03.01.SE.150-1.EZ1.bin as part of my troubleshooting but this has not made a difference.
Does anyone have any advice? I am starting to wish I spec'd 3750X's instead!!
Thanks

Cannot connect 4-port switch to hub3

Hi, recently had infinity installed and we are absolutely impressed with it and speeds in excess of 75down which is fantastic!
So the setup we have is the router downstairs, and an ethernet going from that to the 4-port switch which was all set up for us by the engineer.
What I wanted to do however, was to plug another 4-port switch (a white 'PEAK' branded wifi switch) into one of the 4 ports of the hub3 in order to increase the capacity up to 7 ethernet sockets.
This setup worked fine when we was with sky over on the old DSL line where the 4-port swtich simply went into skys netgear switch and worked automatic.
However, since switching to bt infinity, for whatever reason, this white switch will not work with BT's hub3. By plugging a computer into the white switch, i can access the actual routers setup page by typing in 192.168.1.254, and can access all the settings. The following settings come up...
INTERNET: Connection Method - DHCP
Internet IP Address: 192.168.1.67
LAN: IP Address 192.168.1.254
LAN: Network Mask 255.255.255.0
LAN DHCP Server: ON
But like I say, the switch, which has got a cable coming from one of the HUB3's 4 ports into my old white PEAK routers INTERNET port, will not allow my old switch to access the internet.
So im really confused. Why will my old switch not work on the BT Infinity HUB3?

Thanks for both your replies. I read them earlier in the day, and been trying a few things out...
1st, I tried plugging the hub3 into lan4 on the peak switch, and the other 2 (sky and roku), along with my laptop for testing purposes into 1, 2 and 3, and all worked great!
Well... all wasnt so great, the connection was sporadic and intermittent, ping was low, and throughput was fast, but it was on and off. A speedtest.net would stall, web links sometimes took 2 or 3 clicks, and so on.
So what have I learnt? Well, the fact that it has an internet port (which I was wrongly trying to use before), means that it isnt a basic switch.
So today, I went and bought http://www.tp-link.dk/products/details/?model=TL-SF1005D. Plugged that in the same way, and everything works perfect!
So now, I have the router (downstairs), plugged into the hub3 (upstairs via existing ethernet run throuth the stairs), 3 ports plugged into 2 pc's and 1 youview box, the 4th into a powerline socket upstairs,, with the other powerline socket plugged in downstairs behind the TV, connecting to the tp-link switch socket 5, with the sky+HD and Roku XL plugged into 1 and 2 on the switch respectively, and after testing I now everything running lightening fast with HD on demand, and the world is good
So thanks for both your advice, i learnt a bit today.

Faulty but refused a port switch as they are alloc...

First off someone at BT/Openreach really does need to address what is a truly broken issue management and escallation process at Openreach. It doesn't take much effort to provide feedback and information to Customers yet Openreach appear to be completely incapable of this.
So, 23rd Aug my infinity that has been working for months goes from 22Mbps down/5Mbps up to 10Kbps down/7.5Mbps up - yes, 10k!
I normally use a draytek 2750n so I swapped that out and put back the standard Openreach modem and HH3 that BT supply - no change in speeds.
So I call BT, go through all the normal off and ons until an engineer visit to the house is arranged for the following weds. The engineer spends a few hours trying to sort it out, confirms that all is fine between the house and the cabinet but i need a port switch - Openreach refuse this as the ports are assigned for new installs. I'm supposed to get a call back to arrange this - no call.
I call BT and they say an engineer will visit the cabinet/exchange on Monday 3rd (this week). I get home in the evening to find that nothing has changed but do have a message on the answerphone from the Engineer informing me that he has sorted a few things out and given a few days everything will be back to normal - that does happen right?!?
I'm straight on the phone to BT who arrange an engineer who will sort everything out today and call me to confirm so that I can check. I check at 5pm today - no change. I ring BT - Openreach cancelled the Engineer because the engineer from Monday closed his call - after I'd rung on Monday and booked for today.
During this call I was told that the Engineer from Monday 3rd had also requested a port switch and been refused, no spare ports ( again I expect they are reserved for new Customers). So despite the message I'd received he knew that a port switch was required. I'm told that an engineer is now coming onFriday and will check everything is working. My obvious question is 'are there now ports available for existing customers'. The response was that the engineer would find out on Friday and book an Engineer for another date if not.
Now as a customer who has a contract with BT I expect faults to be fixed in a timely manner without constant chasing by myself. I do not expect BT to refuse to fix my fault becuase all spare ports are allocated for new customers - surely a breach of contract.
I've now been without Infinity for 2 weeks and I have little faith that Openreach will resolve it next time or put in place the required Engineers to resolve the problem.
Anyone any ideas how I can get a resolution to the port switch I require and ensure that Openreach do what needs to be done?

So another engineer visit to fix the problem. First of all he tries to get out of switching the port but we stand firm and tell him that two other engineers have already identified the issue. Off he goes to do a lift and switch ?
He comesback, plugs in his magic box and tells my Wife that it says we should get 25mb - I'm guessing that this device just reads the profile rather than testing the line as when he used http://www.speedtest.bbmax.co.uk/ to test the speed on our laptop rather than any of the BT sites and showed my Wife that he had managed to get 5Mbps and not to worry as this would increase back over 20Mbps overnight. He did mention that
I get home this evening to discover that we are getting 10k downstream, 4.5m up. How is this possible - well the only way I can think is that the ports have been switched back again. Even if thats not the case why would the speed decrease from what he tested to such a degree and why would he expect the speed to increase by 400%+ overnight?
So, 15 days after reporting the fault, 3 engineers, 3 hours on the phone to a call centre that isnt even the company responsible for the problem and the only thing that has been acheived is a slight reduction in upstream speed. Unreal
Oh, and the call I was promised by a manager in India that would be between 7 pm and 8 tonight to confirm that everything was fixed - i guess it was too much to expect that to happen.
Here's hoping that the Mods are able to help as I don't know what else to do.

Using 79xx Phone PC access port to connect a Netgear 5 port switch

Cisco documentation indicates that on 79xx phones you can "Use the PC access port to connect a network device, such as a computer, to the phone". What types of problems might be encountered if that device is a Netgear Fast Ethernet Unmanaged FS105 five port switch? Is there any documentation indicating whether this "supported" or "not supported"?
I know that the speed on the devices connected to the Netgear will be cut to 10/100. The devices connected to the Netgear would include - at a minimum - a computer and a Cisco wireless access point. Other devices which might be connected could include additional computers and/or a printer.
The computer(s) would also need to access a distributed video stream daily.
We are running CallManager 8.6.2.21900-5 with phone types: 7940, 7941, 7945, 7965
Thanks for any insight you might be able to provide.

Will Cisco support you doing this? Not likely.
Will it work? I suppose, in theory, it should. Just don't complain if it doesn't.

4 port switch to 8 port 1GB, iMac loses ethernet cable

We are getting prepped for an upgrade from our 10MB internet service to 1GB fiber. We were trying to do the easy things first, but have run into an unexpected problem.
We use a 4 port switch to distribute our current DSL signal to several locations in the house (never with any problem.) To handle the additional speed and add extra spots, we bought and installed an 8 port 1GB switch in exactly the same location. Everything works as previously except my iMac.
For whatever reason (and I would LOVE to hear opinions on why) the Mac now says it does not see an ethernet cable (the same cable, of course) and I lose the internet. The only change is the switch itself.
Am I missing a requirement for changing settings on the Mac to deal with this switch? We have not changed the input speed, we are still on a 10MB DSL. We're stumped.
BTW, if I plug the 8 port switch in, and use a 1GB USB dongle with my current ethernet cable, the iMac works fine. And it still works with the 4 port switch. Definitely not a cable problem. Stumped. Many thanks for any and all ideas.

Replacing high density port switch/blade strategy

Hello,
I'm looking for strategies in replacing 48 port blades/switches while minimizing downtime. Our management wants to know how long it would take to replace a switch and re-cable it. So I'm trying to find some best practices on replacing switches/blades and how to maintain cable to port integrity when moving between switches/blades. The only thing I've really found comes from data center infrastructure, where they stress the importance of labelling cables.
I was wondering if anyone else had other strategies they use when replacing high density port switches/blades
Thanks in advance

patrickpaez wrote: Leo,Thanks for the response. What about places where your rack or chasis is full and you have to remove the exsisting chasis or blade inorder to add the replacement equipement?
Label, Label, Label.
I can't stress it enough, especially if you're trying to do a "mirror" replacement and have everything working exactly the same as it was before. Don't rely on memory, don't rely on out-of-date documentation - label every cable
If you're talking physical switches, then configure them FIRST to match your existing configuration (VLAN's, SVI's, Trunks etc etc), then label *every* cable plugged into your existing switch, pull the old one out, mount the new one, then put your cables back into place based on the labels.
If you're talking blades, the process is about the same except you *shouldn't* have to worry about configuring first - if you're doing a slot-for-slot replacement, the port designations should remain the same, and your existing config should just take effect on reboot.
If it's an additional module in an empty slot, just plug the module in, duplicate the configuration from the existing module, and move your cables one-by-one to matching ports on the new blade.
Cheers
Trap for new players in blade/modular environments - make DAMN sure the IOS version you're running actually supports the module you're installing - or you're going to end up in a mess!
