Cisco 2950 trunk s shutdown problem
i have a network on fiber.i have use cisco 2950 switches in that topolgy.my problem is that sometimes the trunk ports automatically shutdown which creates a lot of problem.when the ports shutdown the cpu usage of switch goes to 66.normally it remains at 30.secondly i give redunant path to every vlan and now the vlan spanning tree has stopped because cisco 2950 doesnot support more than 64 stp.
What could be the problem?or iam thinking about the bandwidth..How much bandwidth does cisco 2950 switch can max carry?

If the trunk port went into shutdown, then there's gotta be a reason why.
Can you post the output to the command "sh post" particularly the time when the port went "down"?

Configuring wired 802.1x with Cisco 2950 and NPS 2012 problem
Hi,
I am trying to setup wired authentication on my corporate network. For testing purposes, I have setup a Cisco 2950 switch for RADIUS authentication.
On the first day of the test, access messages were appearing on the event log of the 2012 Server and we were trying to address the issues with EAP and policy.(Network Policy and Access services)
Then, suddenly no events are written to the event log for the wired authentication. Accounting data is written to the log file at c:\windows\system32\logfiles, but nothing happens on the event log as if the NPS is not answering. We are using the same server for wireless 802.1x and all is working fine.
Checking the wired autoconfig log on the client, Restart Reason : Onex Auth Timeout appears.
Logging seems to be configured properly, there are no entries in event log. Below is the debug information from the 2950 switch;

Cisco 2950 Gigabit interface trunking
This is the small part of the network design that i want to seek advice from the forum .
++ we have two cisco 2950 switch
switch1 ==gigabit trunk == switch2 .
we want trunking to enable between these two two switches by using there gigabit ethernet interface ie
switch 1 interface GigabitEthernet0/1 is connected to switch 2 interface GigabitEthernet0/1 and switch 1 interface GigabitEthernet0/2 is connected to switch 2 interface GigabitEthernet0/2.
i need advice in following areas
++ what cable do we need to connect these switches (i guess cross over cable will do )
++ do we have configuration on the tech tip page
for achieving the same ?Hello,
for the trunk connection you need a four twisted-pair crossover cable:
Figure B-11 Four Twisted-Pair Crossover Cable Schematics for 10/100/1000 and 1000BASE-T Ports
http://www.cisco.com/en/US/partner/products/hw/switches/ps628/products_installation_guide_chapter09186a0080346679.html#wp1020386
You can either configure 802.1Q or an ISL trunks between your switches. For 802.1Q the configuration would look like this:
Switch1
interface GigabitEthernet0/1
switchport trunk encapuslation dot1q
switchport mode trunk
interface GigabitEthernet0/2
switchport trunk encapsulation dot1q
switchport mode trunk
Switch2
interface GigabitEthernet0/1
switchport trunk encapuslation dot1q
switchport mode trunk
interface GigabitEthernet0/2
switchport trunk encapsulation dot1q
switchport mode trunk
And for ISL encapsulation, the configuration would look like this:
Switch1
interface GigabitEthernet0/1
switchport trunk encapuslation isl
switchport mode trunk
interface GigabitEthernet0/2
switchport trunk encapsulation isl
switchport mode trunk
Switch2
interface GigabitEthernet0/1
switchport trunk encapuslation isl
switchport mode trunk
interface GigabitEthernet0/2
switchport trunk encapsulation isl
switchport mode trunk
You could also configure a GigaChannel to bind both interfaces into one logical link, for better throughput. For 802.1Q:
Switch1
interface Port-channel1
switchport trunk encapsulation dot1q
switchport mode trunk
interface GigabitEthernet0/1
switchport trunk encapuslation dot1q
switchport mode trunk
channel-group 1 mode on
interface GigabitEthernet0/2
switchport trunk encapsulation dot1q
switchport mode trunk
channel-group 1 mode on
Switch2
interface Port-channel1
switchport trunk encapsulation dot1q
switchport mode trunk
interface GigabitEthernet0/1
switchport trunk encapuslation dot1q
switchport mode trunk
channel-group 1 mode on
interface GigabitEthernet0/2
switchport trunk encapsulation dot1q
switchport mode trunk
channel-group 1 mode on
And for ISL:
Switch1
interface Port-channel1
switchport trunk encapsulation isl
switchport mode trunk
interface GigabitEthernet0/1
switchport trunk encapuslation isl
switchport mode trunk
channel-group 1 mode on
interface GigabitEthernet0/2
switchport trunk encapsulation isl
switchport mode trunk
channel-group 1 mode on
Switch2
interface Port-channel1
switchport trunk encapsulation isl
switchport mode trunk
interface GigabitEthernet0/1
switchport trunk encapuslation isl
switchport mode trunk
channel-group 1 mode on
interface GigabitEthernet0/2
switchport trunk encapsulation isl
switchport mode trunk

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.

i have a cisco 2950 switch.in the network which i want to create out of 24 ports i want two ports should be isolated from all other ports. and there should be only two ports among the remaining which can access those two ports and and also communicate with rest.
Hi Kalyan,
What u mean by accessing the ports???? If it just passing the traffic means you better configure those two ports in a single vlan each. and other ports in a different vlan.
But if u want to have two ports which needs to pass all traffic, better be in trunk mode allowing all the three vlans.
You can pass the three vlans thro. this two ports but if you want commuicate between vlans, you should have either L3 device or router to do the intervlan traffic.
Rate if it helps
Rgs, -
I have 2 Cisco 2950 switches one for each network in my office. One switch is full the other only has 8 ports used. Since both swithches are 24 port I though I might be able to split the switch on the underused network and allocate 12 ports on it to the other busy network.
I assume I have to create 2 Vlans on the switch, but can I assign 1 vlan with the same IP as the other switch and simply patch them together.Hi Mark,
first of all i have a question.... Why do u need ip adresses on your switch? just to manage them?
If so here is my suggestion...
u should assign 3 vlans not 2... make one of them your management vlan and assing an ip addresses from a diffent subnet than your nodes. Then configure a trunk between the two switches. Remember to make your management vlan the native vlan (switchport trunk native vlan ).
Next u assign each port to the appropriate vlan and your done.
If u manage the switches via console port, forget about ip adresses... u dont need one. just make two vlans and assign the ports (dont forget the trunk).

Cisco 2950 MT-RJ ports - Connect two switches?
Hi Everyone,
I'm wondering if I can connect two cisco 2950s together via the two MT-RJ ports they have?
Basically, I'd like the fibre ports to be the trunk between the two switches if possible
I have two of these:
Thanks!Hi,
Yes, that is possible. As long as your fiber patch cable is good there should be no issues.

VLAN and STP compitability between Cisco 2950 and SRW2048
How Cisco 2950 and Linksys SRW2048 switches can be combined to work fine with more than one VLAN's and STP?? I want both switches to support three VLAN's and STP for loop free network.Can some body help me out to combine linksys and cisco switches to interconnect to form my Network???
I believe that the SRW2048 is a 48 port managed switch. The easiest way to set the VLAN and STP configuration of is to access the web utility of this switch via 192.168.1.254. You have to go to VLAN Management and he needs to create the VLANs. The default VLAN of the switch is VLAN 1. You need to create 2 more VLANs by choosing the VLAN IDs and the name you want for these VLANs.
After creating the VLANS, you need to determine the LAN of the switch you want to assign to each VLAN and the Trunk port or the port where you need to connect the SRW2048 to the Cisco 2950 switch. Go to the port setting and make this port as “truck”, and leave the other ports as “access”. Go to VLAN to ports and manually allocate the each LAN ports to the desired VLAN ID number. Take note that all ports that are members of VLAN1 should be “untagged” and the rest should be “tagged”. Save the settings you made.
The STP configuration for the SRW2048 can be found also in the web utility. Just go to the Spanning Tree tab and setup your desired STP configuration.
For the Cisco 2950, I am not quite sure on how to create these settings but I saw a useful link that might help you:

Cisco 2950 and Dell Powerconnect 5224
I am trying to Cascade a cisco 2950 and dell powerconnect 5224. I am connecting port 32 on the 2950 and port 24 (gigport) on the dell. Any idea on how I can get the cascading to work? This is what I have on the Dell and the cisco.
Dell Powerconnect 5224:
interface ethernet 1/24
switchport allowed vlan add 1 untagged
switchport native vlan 1
switchport mode trunk
switchport allowed vlan add 1,10 tagged
Cisco 2950:
interface FastEthernet0/32
switchport access vlan 10
switchport mode trunk
Dell documentationon casdcading between powerconnect and catalyst 4000 talks about setting up GVRP on both the dell and cisco switches. However, 2950 doesn't have GVRP.
http://www.dell.com/downloads/global/products/pwcnt/en/app_note_4.pdf
Any ideas, tips. Thanks.Try this instead:
Dell:
interface ethernet 1/24
switchport allowed vlan add 1 untagged
switchport native vlan 1
switchport mode trunk
switchport allowed vlan add 10 tagged
Cisco 2950:
interface FastEthernet0/32
switchport mode trunk
switchport trunk allow vlan 1,10
switchport nonegotiate
You don't need "switchport access vlan 10" on the Cisco because it's not in access mode, it's in trunk mode. And on the Dell you don't want vlan 1 to be tagged and untagged.
Good luck. -

Random shutdown problem on G5 dual 2.3 GHz w/OS 10.4.7
Hello,
I’m using a dual 2.3 GHz G5, and it’s been working flawlessly since I bought it about a year ago. Until yesterday, I was running OS 10.4.5. Yesterday I upgraded to 10.4.7, and as soon as I booted up after the install, I started having a maddening problem with my computer randomly shutting down. (Not sleeping, but a complete power down.)
At first, the shutdown would happen immediately after powering up; my computer wouldn’t even make it to the blue progress bar. I zapped the PRAM and tried something I found online about unplugging the computer for 15 seconds, then plugging it back in. It now boots up, and I can log in, but the computer still shuts down randomly.
There seems to be no pattern to the shutdowns. I tried taxing the processor by opening and resampling huge Photoshop files while lots of other apps were open, and things were fine. Then it would conk out while I was composing an email.
I’ve heard of this random shutdown problem affecting Macbooks, but I have yet to find anything about G5 towers and OS 10.4.7. Does anyone have any info/advice?
Many thanks.
G5 dual 2.3 GHz Mac OS X (10.4.7) 2.5 GB RAM, 250 GB HD
G5 dual 2.3 GHz Mac OS X (10.4.7) 2.5 GB RAM, 250 GB HDThanks for the advice. I did check the system.log in Console and found the following altert:
PMU FORCED SHUTDOWN, CAUSE = -122
Now, since my computer is just over a year old, and since this problem happened immediately after applying the 10.4.7 OS update, I found it hard to believe that my hardware could be responsible. After 2 days of troubleshooting, I was stumped; after a 2-hour service call, so was Apple tech support. I ended up doing an archive and install back down to 10.4.5, and all is well.
I tested this issue on other machines running 10.4.7 and had no problems. It seems that the following specific combination of elements triggered the problem:
• PowerMac G5 dual 2.3 GHz (dual 1.8 machines did not exhibit the same problem)
• OS 10.4.7
• Logging in with Open Directory/Active Directory mobile profiles
• iTunes 7
Bottom line: if you’re using a dual 2.3 GHz PowerMac with mobile OD/AD profiles, do not update to 10.4.7, and steer clear of iTunes 7, at least until there is a patch update available.
(And Apple wants to be taken seriously in the enterprise market?)

Clock problem and shutdown problem! Are they related?
Having a problem with my Dual 2 GHz Power Mac G5
A few days ago I noticed that my clock was not showing in the menu bar in the upper right corner of my desktop.
I went into System Preferences and went to Date & Time. Under the clock tab “Show Date and Time in Menu Bar” the box was not checked off. I checked it off and went to the “Date and Time” tab. The date and time was correct. I then checked the box “Click the lock to prevent further changes” to lock it. The date and time did not show up in the menu bar. I then went back to the tab “Show Date and Time in Menu Bar” and the box I checked was not checked off even thought the lock was still locked.
I then moved my cursor up to the menu bar in the upper right corner to see what would happen and the spinning beach ball started up but only for the original icons such as Bluetooth, Mobile Me (which I do not use), Time Machine, Spaces (doesn’t indicated the number when I switch Spaces, etc. The icons Norton Anti Virus and Tech Tool Pro in the menu bar are okay.
Also, when I attempt to shut down my computer the system clears the icons from my desktop except for a picture I have on my desktop and I get a gray wheel spinning and the system just hangs until I press and hold the on/off switch. I don’t know if the clock and shutdown problems are related.
The only new software I loaded recently was Skype with Logitech WebCam for the Mac and Quicken 2007 (Had a problem with Quicken 2006). They both are working okay.
And ideas on why I cannot get my clock to show up and my computer to shutdown?You may have to consider a new post in the Hardware forum area for the computer
model and build/year; if there is a possibility of some basis the matter could be in
the machine and not the software running within it.
Your last two/three posts are in the Leopard 10.5(.8) forum area and do indicate
some kind of problem where troubleshooting the computer to discover if the matter
at hand would be either hardware or software based, may be the way to go.
The link to the 10.6 Snow Leopard forum won't be of help if your computer is a
PPC-based G5 tower, or other older pre-Intel configuration. And I remember
your earlier questions about the iMac G4 and some other issues in the past.
You may ask the moderators to put your post in a new thread of its own, in the
Leopard 10.5 area; so as to not 'piggy-back' another topic; even though some
of the odd issues you've had seem similar to this OP's topic line and appear to
be in the same general series of hardware. {The question here seems valid.}
The routine suggestions to check, test, verify, and perhaps repair or replace
the system; save a bootable clone to suitable external standalone device if
testing a suspect computer's viability is recommended; and the basics if not
already tried to help isolate the issue(s) as you've posted elsewhere, may be
of some help to try and do; so in that matter, a new thread of your own is best
for your own directed feedback. Since this kind of advice applies to most any
situation, including troubleshooting what may be hardware or software, I'm
adding my two and three-tenths cents worth here.
Your original included Apple Hardware Test may be of some help, in the process
of elimination; but is not conclusive, so other methods would be also suggested.
Some ideas appear to cover the same ground. However, system corruption or
disc failure can also manifest itself in odd ways & affect things indirectly for a time.

So, at the risk of inadvertently alienating the OP, I am posting this as
a general help to following readers at some later time; and it may not
be too simple for a refresh course.
Some software issues can be resolved by repairing disk permissions,
and re-applying the last OS X update Combo file over the same one
already in the system; or if not up-to-date already, check & repair all
the general items and then apply the last Combo update.
A too-full hard disk drive can compromise the system integrity, so that
is a matter of course to keep up on what resources exist and remain
for the OS X to function correctly and for apps to multi-task together.
However that works out...
Good luck & happy computing! -
Are the replacement Heatsinks fixing people's Random Shutdown problems?
Is the replacement heatsink (the shorter one) still the method of choice from Apple for fixing Random Shutdown problems?
Is it working for people who've had it done recently?Does this max out the CPU?
Yes. People who advocate this are testing to see if it's possible to induce a "random" shut down.
Why would anyone want to do that?
Good question. I've seen two reasons put forward: (a) It's better to make it happen now yourself rather let it strike out of the blue at some later date (and if running this test doesn't induce RSDs you can feel confident that your computer is probably immune); (b) If you take your MacBook to an Apple Store it could be useful for demonstrating to an Apple "genius" that your computer has the problem, especially if your shutdowns are infrequent.
(personally, I don't agree with (a))

Late 2013 13"MBP-Shutdown Problem
I was having shutdown problems with my Late 2013 MBP 13"-the MBP would go to the gray screen and the small pinwheel would progress to different hash marks every 3-5 seconds, the machine would not shutdown at all, it was stalled, so I called Apple and we trouble shot. During our troubleshooting adventure it dawned on me that the problem could be related to my Antivirus Software-Intego. So I went ahead and disabled the real-time scanner and...viola, it shutdown with no problem. So I am letting people know that as of currently, Intego's real time scanner could cause issues during shutdown. I placed it on a scheduled scan and placed everything else on; no issues now.
So my only question would be; I have the same antivirus software on my early 2012 15" MBP with no issues. Though, I do remember having very slow shutdowns for sometime and then it seemed to resolve itself. The major difference in these two machines appears to be, besides the retina displays, the mechanical HDD vs SSD. My 15" (early 2012) has two Mech. HDD while the new 13" has of course SSD. I am thinking the antivirus software isn't handling the SSD appropriately.
Any-how, I just wanted to give a quick (though detailed) heads up.OK, I messed around with this issue over the weekend. Here's what I did:
1. Used iPad 3 until I have run battery down to about 50%
2. Plug in to left USB port on Late 2013 rMBP. Battery icon starts displaying "flip-flop" behavior.
3. Replug into right side USB....no problem, all behaving well.
4. Tried plugging in my iPhone 4s into same cable on left USB port, no problem.
5. Replug iPhone into right side USB....again no problem, all behaving well.
Here's where it got interesting:
6. Exchange charging cable for a newer cable with the smaller-sized 30-pin dock connector.
7. Plug iPad into left USB port...and viola! Battery charging icon is steady...no "flip-flop"!
8. Replug into right side USB....no problem there either, all seems normal.
I have no idea what's going on, but this seemed to have solved prolem. BTW, the older cable, when plugged into wall charger, charges the iPad just fine.
Hope this helps someone else with this problem. -
I tried updating to 10.5.6 this evening (I should have read these forums first to be forewarned...but anyway..). I was prompted to restart and ever since I have had difficulty shutting down. All icons, the dock, desktop and menu bars switch off (as usual) and the screen goes to blue and just sits there. The HD is spinning and the screen goes from a light blue to a slightly darker shade of that blue and the cursor shows up on the screen as well. But the computer just doesn't shut down.
Is there a way to force shutdown (other than holding the power button down)??
Also, what can I do to help fix the problem.I ran disk utility and no apparent problems came up.
I then went hunting in other threads for clues and found a link to the Apple download updates page which gave me an idea.....
Since my shutdown problems started when I was prompted to restart for the 10.5.6 update I thought to re-install the 10.5.5 update.
This seems to have worked. No idea why 10.5.6 would lock up the shutdown process but at least I get a clean shutdown now.
Anyone have a similar issue??
