Weird Display on 2950 Switch

When I connect with my Cisco 2950 Switch, I can see the weird kind of language as per my attachment.
Switch is working good with Cisco IP phones connected with it.
Can anyone help ?

Check your terminal settings... default is 9600 8n1... You might have changed the speed from either your terminal program or your serial connection.

Duplex Mismatch when connecting ip phone with 2950 switch

When I connect my Cisco IP Phone 7960 with 2950 Switch (any access port within voice vlan), I get the message on Port duplex mismatch but the phone works properly.
From my switch the speed setting is 100/Full but from the Phone its Auto.
My Question is when I try to change duplex settings from Phone, it doesn't gives me any option instead only one option available to save so kindly someone tell me the best way to fix this from Phone or do I have to change the duplex from switch to AUTO ?

Thanks but When I connect with my Cisco 2950 Switch, I can see the weird kind of language as per my attachment.
It wasn't yesterday when I first configured from scratch but just seen today.

iPhone 4 OS 7.1.2 (11D257) display normal when switching on, turns to very high contrast with bright primary colours only, no tonal graduation.Initially problem arose every time I switched the Camera on, but has worsened such that any application can cause it. In Camera, after a short time screen goes black. Also, Wifi no longer works.

Application timeouts w/ subnet devices using 2950 switching

I am having problems with process critical PC workstations that access other workstations and servers.
This consists of a standalone subnet network (static IP's) using a 2950 switch that is also part of a LAN domain.
It appears when there is a LAN issue my subnet workstations experiences problems trying to access it's dedicated servers that are wired all within the subnet 2950 switch.
Could this be that the 2950 switch is looking for the DCHP or domain controller, slowing down my standalone devices?

No, it's not likely.
The only thing affected by DHCP or domain info would be for managemnt (like being able to telnet into the switch).
Switches see the frame, look at the MACs, and either forward or flood the frame. That's all they do (acting as yer basic plain ol' switch).
Other features, such as broadcast/storm control, bad media (cabling), excessive broadcasts (broadcasts are also propagated out all ports and consume considerable bandwidth everywhere), and other things, like QOS settings, buffer parameters, spanning tree can also have a serious negative impact on your throughput, including many disappearing frames.
SO ... let's start by taking a look at a Show Version, and (at least) a Show Run (sanitized, if necessary).
It would also help if you could describe the nature of the traffic that is being dropped / lost / filtered (i,e., database, large graphics files, multicast streaming, file transfers, etc.
What troubleshooting have you tried so far?
Did it ever work, worked ... but not very well, worked well until you updated the IOS ....
Have you checked your LAN for virus / worm / trojan traffic (getting back to huge broadcasts)?
Are you getting any media errors? (Show interface)
Do you run many-to-one, many-to-many, any trunks? any EtherChannel?
Are you getting any "Duplex Mismatch" errors?
Have you tried another switch (for diagnostics to rule out the workstations & media)?
This ought to be enough to get started. get it collected and post it, then we can take another shot at it.
Good Luck

Maintaining clock settings on a 2950 switch?

I have set up external NTP synchronization on a 2950 switch which works fine while the switch is powered on. However if the switch is cycled with a "reload" command, the time established is way off once the switch comes back up. Is this the expected behaviour?
Thanks.

BTW:
Also sometimes difficult finding mention whether the hardware supports an on-board calendar. I've found using the ntp update-calendar both often a fast method to help in determining this, and a great way to keep the calendar accurate across reboots/reloads (if you're using NTP).

Should iphone 4 receive messages when turned off and display them when switched back on

should iphone 4 receive messages when turned off and display them when switched back on

It's up to the cellular carrier, but I believe most (if not all) will enqueue the messages when your iPhone is off.
So generally speaking, a few minutes after you turn your iPhone on, your messages should display. Similarly, your voicemails would arrive.

WordPress page, weird display in Firefox-Mac

Hello,
My client has a WordPress blog, and he tells me that when he
view his latest
post in Firefox/Mac, he sees a "milky white overlay" on top
of the page, and
that this "overlay" prevents him from being able to click
anywhere where it
is.
He says "It does not seem to affect Firefox on Linux nor
Safari on Mac."
Here's the blog, and it's the current post where he sees the
weird display:
http://blog.miraverse.com/
Here's a screenshot (reduced slightly) showing the "white
overlay":
http://ayersvirtual.com/temp/firefox-overlay2.jpg
I don't see this in any browser on any of my PCs.
Does anyone see that problem in your browser? (Would
appreciate any
Firefox/Mac checks in particular.)
Does anyone have a clue what might be causing it??
Thanks very much in advance for any help.

Can't open console to 2950 switch

Howdy all,
I'm after inheriting a cisco 2950 switch in my new job and I do not know the enable password for it. I went about following the "password recovery procedure" but am getting nowhere.
http://www.cisco.com/warp/public/474/pswdrec_2500.html
I have tried connecting to the switch after powering it up but cannot open a session over the console port. I've tried using both COM ports on my laptop with all the variations of the flow control setting but no joy.
I took a look at an old config file that was saved on the network for the switch and found this at the end:
LINE CON 0
TRANSPORT INPUT NONE
Is this stopping me from completing the password reset when the switch is booting up??? All advice welcomed.
Regards,
PaddyIrishman

HI Paddy, [Pls Rate if HELPS]
"Transport Input None" command will prevent you from accessing the Device.
Refer link below for CISCO 2950 Swtich Password Recovery Procedure Document:
http://www.cisco.com/warp/public/474/pswdrec_2900xl.html
Refer step by step procedure (quick ref):
1. Unplug the power cable
2. Hold down the mode button while replugging the power cable
3. Type flash_init over the console
4. Type load_helper
5. Type Dir flash:
//make sure to type the semi-colons
6. Type rename flash:config.tdt flash:config.old
//the password is contained in the config.txt fil.e
7. Type boot
//this reboots the system
8. Type n to skip the initial setup config
9. Type enable
//this takes you to the enable mode
10. Type rename flash:config.old flash:config.txt
11. Save config.txt to system
#copy flash:config.txt system:running-config
12. Enter config mode and change the password
#cofig t
#no enable secret
//this applies only if the enable secret password was created
13. Finally write the changes to memory
#write memory
PLS RATE if HELPS

2008 macbook pro 15" (Santa Rosa) weird display color and vertical lines

I have the 2008 macbook pro 15" (Santa Rosa). After my upgrade to mac os x lion (10.8.2), I noticed that periodically the screen either turns to weird display color and have horizontal lines on screen. This happens mostly during start up and lasts for about a min or two. Does this happen because of a faulty graphics card? I have NVIDIA GeForce 8600M GT 256 MB card on this macbook pro. Please advice

Nope - it sounds as if you've GPU issues and the discrete GPU is soldered onto the logic board. take your new machine into your local Apple Store for a replacement. Don't wait too long!

Catalyst 2950 Switch flash_init error

Hi Everyone,
I'm new to Cisco products and have a small home lab set up. I have a Catalyst 2950 switch that I would like to restore to factory defaults. Here is the issue I'm having and can't figure out.
I pull the power, telnet into the console port, hold the mode button and restore power. The boot loader (Version 12.1(11r) starts and says the usual message the system was interrupted prior to flash initialization (Paraphrasing here)
I get to the switch: command line, enter flash_init. Flash states it initialized and then all I get is a < with an underscore under it prompt. Anything I try to type comes up as bizarre characters and I can not get back to a switch: prompt unless I reboot the switch manually. Unsure of what to do here.
Thanks in advance!
-Matt

Hi mattymattlynch
Check the workaround on the following documents:
http://www.cisco.com/c/en/us/support/docs/switches/catalyst-2950-series-switches/41845-192.html
http://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst2950/software/release/12-1_22_ea11x/configuration/guide/scg/swtrbl.html
If no luck , the flash might be corrupted and requires a replacement.
Hope this helps

You need to perform a DFU Mode Restore of the iPhone with iTunes on computer. You must also have a SIM card of the original Carrier that this iPhone was produced for.

Apple wired Dot1X - on Cisco 2950 switches

Hi, I have an issue with Apple desktop computers running 10.7 and 10.8 MacOS.
The problem is that we have only 2950 switches and we are very limited with what we can do on them, so we wanted basic DOT1X user authentication and VLAN placement. Those two are working great, except when user logs off, Mac stops sending DOT1X and port becomes unauthenticated. We alleviated that issue by using guest-vlan for failed dot1x authentications, but now we have a problem that once user logs in, there is no session change on 2950 and it doesn’t even try to authenticate user until we bounce the port.
Is there any way to fix this, on Cisco switch or Mac computer? One of the things that crossed my mind is bouncing port on Mac PC using some kind of logon script?
Has anyone else had this issue and was able to solve it?
Thanks.

Hello Align,
Cisco 2950 switch with 12.1(9) supports 802.1 x authentications. As you are saying that you already configured 802.1x authentication and its working fine. I think there is problem with your MAC OS configuration. Please follow the below link to configure 802.1x on Apple.

Ideapad u300 screen not working - covered with some weird displays

A few days when I turned on my laptop, I could not see the log in box since the screen was mostly covered by some weird displays. I can only see the down right corner of the screen where I can choose to shut down or restart. But I can see the whole screen normally if I connect the laptop with a external screen, like a TV screen with HDMI cable. Does it mean that the laptop screen is broken and I need to get a replacement?

Hi there,So I've had my laptop for a while now and the touch screen stopped working a long time ago as well. I figured that I would wait until maybe someone posted a solution somewhere but there hasn't been any posts about it (that I could find) and it's been a really long time so I figured I would ask. So here's the problem. Touch screen stopped working. No idea why. Quite suddenly the touch screen decided to no longer work. I checked the driver and the computer says its functioning properly. I tried to see if there was some kind of update that I should download, and my efforts yet again were in vain. Alas, I figured the more knowledgable might be able to guide me in the right direction so....any ideas? With thanks,MattHave you tried restoring to factory condition through the use of OKR?

Does 2950 switch support IP SLA ?

Hi,
I am trying to implement IP SLA.
Can I implement it on layer2 switches?
Regards
skrao

The Cisco 2950 switches seem to suport legacy RTR (Response Time Reporter) NOT IP SLA. SLA has been called various titles during its evolution to SLA. The feature comparison chart below states IP SLA is NOT availalbe on the 2950.
http://packetlife.net/wiki/feature-comparison-catalyst-2950-2960-3550-3560/
Indeed I cannot access IP SLA as a cmd under either 12.1(14)EA1a or 12.1(22)EA13 on the 2950 switches I have available! IP SLA is however available on the 3550 switches I am running!
I suggest it may well be the case that the 2950s use the RTR command instead.
http://www.cisco.com/en/US/docs/ios/12_3t/fun/command/reference/cfrgt_10.html
Information generally though for RTR is scarce, because I suggest of Search Engine 'bleed' referencing RTR as 'Router'!
My advice is to explore RTR
https://supportforums.cisco.com/thread/2152754
...work with what is availalable rather than dwelling on what is not, or choose to revise just the theory...if your need is mostly for exams.
The good news is ALS1|(config)#RTR responder
...reportedly works just as well as #ip sla responder

Some 2950 switch ports led turn amber even without cable connection

Hello. Due to a likely NIC problem, after connecting my laptop to a port on the 2950 switch, the led turns amber even after disconnecting the cable.
2 ports on the switch are having this problems. Ideally the led should be off when nothing is connected.
Please, how can I correct this problem without restarting the switch because its in a production environment.
Eddy

Hello,
which two switchports are amber? Try toggling the port LED modes by pressing the mode button.
Have a look at
http://www.cisco.com/en/US/products/hw/switches/ps628/products_installation_guide_chapter09186a008007e889.html#xtocid41699
for the different port modes meanings and their respective usage of port LEDs.
It would also be helpful to see the port status from the switch CLI in case the procedure above didn´t solve the problem.
Hope this helps
