Catalyst 3500

I have several catalyst 3500 XL (3512) switches that are going down and ports 3, 7, and 11 light up amber. I try to console in with a laptop and can't get a response. Any suggestions on how to fix this?

Two of the ports connected to a PC and one had nothing connected. I've disconnected everything and no luck.
What I mean is that I have several 3512 switches (6) and I've had three just stop working and not responding. One I was able to console into, but I couldn't reload the IOS. This one doesn't respond at all except sometimes when I plug it back in I get a tilde(~) or a C.

Resurrection of Catalyst 3500 seriesXL

Hi! I got not working Catalyst 3500 seriesXL with so symptoms:
After powering on "system", "rps" and "speed" leds are glowing. Leds of ports with numbers 6, 10, 14, 18, 22 are glowing too.
Console port doesn't send any information... What can I do to brighten device?
PS
Step by step like:
- Unplug the power cord.
- Hold down the MODE button located on the left side of the front panel, while reconnecting the power cable to the switch
- Release the MODE button after the STAT LED goes out. You should be at the switch: prompt.
Doesn't work... Console still shows nothing, but "system", "rps" and "speed" leds stop glowing

You are saying that those rps, System and speed led's are glowing.Which color led's are on.Green or Amber?let me know regarding this.I think the following URL will be helpful for u to diagonise and solve the problem.Because, it contains a detailed description of the switch front panel.

Reset catalyst 3500 XL series to factory defaults

Does anyone know the command or procedure needed to reset a catalyst 3500 XL series switch to factory defaults

I am asuming that you do not know the enable passwords to clear the config. Please follow the URL but when you get to step 9 enter Y(es) to start the configuration script.
http://www.cisco.com/en/US/partner/products/hw/switches/ps628/products_password_recovery09186a0080094184.shtml
If you do have the enable password, enter "write erase" at the enable prompt and reload unit.

Catalyst 3500 XL IOS 12, with VoIP (2 vlan on ports issue)

hi,
i tried to setup a catalyst 3500 XL to run with VoIP.
I need on a port to TAG 2 VLAN (link to the backbone), and on the others to tag one VLAN (voice one) and untagged the data vlan.
unfortunately, through the web interfcae and through the IOS command i could not setup this configuration.
have any idea?
BR,

The uplink to the other switch where you want all the vlans tagged:
conf t
int fa x/x
switch
switch trunk dot1q native vlan 99 >> vlan 99 is a dummy vlan that is not used for any data or voice, we just use this to make sure all is tag since native vlan in dot1q is not tagged with vlan id.
int fa x/x
switchport
switchport trunk dot1 native vlan 2 >> the data vlan.

Trunking SG200's with Catalyst 3500 or 2950

Has anyone here tried to mix a Catalyst switch (say, a 3500 or 2950) with a Cisco SG200-26?
I've got 4 VLANs setup on a 3500: 1 (default), 10, 20, and 30 I've tried to connect a trunk port (GBIC) out of a 3500, into a SG200, with the hopes of being able to assign ports to those particular VLANs on the SG200. So far, I've only been able to work on the default VLAN 1 on the SG200.
The only options I can see, are that I can create VLAN's on the SG200, and assign ports that way --- but that doesn't seem to be passing the VLANs, just creating them fresh again -- I think
Anyone have any thoughts or experience with this?
Recap:
Out of the 3500:
interface GigabitEthernet0/1
description Trunk_To_SG200
switchport trunk encapsulation dot1q
switchport mode trunk
Connected to the SPF port 26 on the SG200-26
Plugging into ports 1-24, I get a DHCP address from the default VLAN 1

Hi Andy, you could make a LLDP policy on the Catalyst to force the Sx200 smart ports to respond.

Satellite M100-165: message Network Cable Unplugged appears

My NEW notebook TOSHIBA M100-165 /model PSMA1E/ with network adapter Intel 10/100 VM Network Adapter have big problem when connected to my office network!!!
So many collisions I can see on my 3COM HUB /model TP800/. But this HUB is perfectly working with other computers in my office /another 5 computers works perfect on this HUB!
When I tried to connect my notebook directly to switch on the floor /model of switch is CISCO Catalyst 3500 series XL/ the message "Network Cable Unplugged" appears.
Only for testing I tried another notebook TOSHIBA in our network but with network adapter Intel 10/100 VE Network Adapter. And this notebook works perfectly.
I hope You can solve my problem as soon as You can!
Thanks in advance!
Best regards!

Hi
I hope that your unit has factory settings and the LAN card is installed and listed properly in device manager. Please check as first if the card is also enabled and configured properly.
Try also to talk with network administrator in your company. He can check all settings and be sure that everything is ok.

4503/4506 - data handling and data flow

I have been tasked to find a document that details how, from start to finish, a packet goes through a 4503/4506 unit. I'm talking a level of detail that includes what portion of RAM the packet goes into once it hits the inbound interface, what parts of the switch handle the analysis (ACLs, et all), and so on, right until the packet is either dropped or forwarded to the outgoing int. As detailed a description as possible, and if a non-model-specific equivalent is available and applicable to this unit, that works as well.
I have been looking through the TechDocs and the like, as well as several attempts at Google (which is well-nigh useless), and no luck thus far.
Thanks in advance for any information provided.

I am not aware of any CCO documents explaining path of a packet/CAT4500 architecture. However, there was a presentation on this at Networkers 2005. If you attended it, you can check it out at

Cannot connect C3548XL to CNA community.

Hello,
I have a WS-C3548-XL-EN switch running ios v12.0(5)WC17 (fc1) that I can not get to connect into a community in CNA v6.1.
I have reset the switch to 'factory defaults', set the IP, SNM, and Default gateway. From other posts I saw that from the config prompt, I needed to enable HTTP (ip http server; ip http authentication enable; ip http path flash:html) and CDP (cdp run), but I still cannot connect.
There must be something I am missing, but being very new to the Cisco ios and this older switch, I don't know where to go.
Any guidance / help would be greatly appreciated.
Thanks in advance.

Connecting SRW2048s over multimode fiber

OK... I'm a fiber / optical networking newbie so I apologize well in advance if my vocabulary is way off in this post... but here goes...
I wanted to upgrade our old 10/100 cisco switches (Catalyst 3500) to something gigabit so I bought some SRW2048s. I'm trying to connect them over our existing multimode fiber (terminated in ST connectors) but they won't link. I bought MGBSX1s to accomplish this task and some LC-ST fiber cable to make the connection. I think I have the ST connections right... on one end it's red/black (for Tx/Rx) for the two ST connectors, and on the other end it's black/red (Rx/Tx). Is there anything I need to do to the switch to make it work right?
Any help would be greatly appreciated!

it's amazing what a little research into a problem can do...
"Autonegotiation (formerly NWay) is an Ethernet procedure..."
looky there... an ethernet procedure probably won't help fiber optic connections....

Port Groups on Multiple switches

Is it possible to create a port group that contains ports from multiple physical switches. We are using Catalyst 3500 series switches that are connected to a Catalyst 6509 running layer 3.

The Etherchannel do not HAVE to be on the same switch.
You may configure an etherchannel between 3 physical switches :
cf http://www.cisco.com/en/US/products/hw/switches/ps5023/products_configuration_example09186a00806cb982.shtml

Long Haul Mode-Conditioning MultiMode GBICs?

We have a fairly large legacy installation of Catalyst 3500s interconnected with 62.5 MMF. Most of the links more than 200m or so have these old Allied Telesyn EX-1002 "range extenders" which are alleged to be able to run up to 2km over MMF without the use of mode conditioning cables. And they do seem to be work as stated, we hve a couple runs just shy of 1km and they have been staying up.
The EX-1002s are starting to die off and I can't find a similar product. Actually, I can't find any technical information at all on the EX-1002, they say "1000-baseX" and seem to be longwave. Since they are said to operate at 2km, is mode conditioning built-in to the device?
The only other way around this is to use generic LX/LH GBICs and mode conditioning cables, which are very expensive. Or maybe just buy some EX-1002s on Ebay?
But, is there a GBIC available that is Catalyst 3500 compatible that can do long-haul multimode gigabit?
Thanks,

At the risk of bumping this topic too late, thanks for all the replies.
We have got everything working, but have not yet bought any mode conditioning cables. It seems to be cheaper for me to fiddle around with randomly swapping GBICs and patch cables, than systematically installing mode conditioning cables on all our links. :-(
A few observations:
- We have 1 or 2 links in the 300 - 400m range operating consistently on 62.5μ MMF with an LX GBIC on one end an an Allied EX-1002 "1000baseSX to 1000baseX" converter on the other (the "1000baseX" is long-wave. don't know if it's 1300 or 1310nm.)
- We have several links in the 300 - 500m range operating consistently on 62.5μ MMF with Allied "range extenders" at each end. We will replace these with LX GBICs and mode conditioning cables as the Allied devices die off.
- We have quite a few SX links operating in the 200 - 300m range, 1000baseSX to 1000baseSX. Occasionally we have had problems getting these to link up with a GBIC on one or both ends. As you would expect from the technical description of mode dispersion this is hit--and-missand randomly dependent on combinations of GBIC and patch cable. SFP-based SX links seem to link up more reliably at distances over 200m. (Perhaps because the tolerances are more precise and/or the SFPs are new and not old GBIC that have been sitting in some network admin's desk for 5 years.)

is this a limitation? I need 4096 Vlans
How can I overcome it. Is there something to change in vtp mode server or transparent???
Please advice
Thanks

Its a limitation of the platform , no way around it . I can't imagine why you would need that many on such a small platform . I would look at my network design if you need that many on a 3500 . You must be running a lot of vlans without spanning tree running per docs
The Catalyst 2912 XL, Catalyst 2924 XL, and Catalyst 2924C XL support only 64 STP instances and 64 VLANs. All other Catalyst 2900 XL switches and all Catalyst 3500 XL switches support 64 STP instances and 250 VLANs.

5505 stuck in VTP transparent

I have a 5505 that refuses to change VTP mode to anything other than transparent. It acts as though it has taken the change, but when you show vtp domain, it shows it as back in transparent mode. The VTP server is a 2924, and there is another 5505 in the network as a client(Which occasionaly slips back to transparent, but takes the change back to client). The only difference between the two 5505s is a slightly older COS on the one that is stuck in transparent ( 6.3(5) vs. 6.4(17) ). Due to the fact that the switch is in heavy usage and they take a while to bring back up, I can't randomly play with it unless I'm fairly sure I've found a solution. There are around 150 VLANs in the database. The server is running VTP V1(as is the 5505 in question). The 5505 does not show any other signs of failure, it's been rock solid otherwise. It's just getting to be a pain having to enter VLAN changes in on 2 switches instead of one. The domain name is the same. I can't find anything in the Cisco release notes that ever shows this as a known problem.

The vtp server should not be the 2924 which may be your problem . These will only support like 64 spanning tree instances so anything above that means spanning tree is not working for those vlans . The 2924 should be a client and you should manually prune the connecting links of vlans that are not needed on the 2924 . Always use the more powerful box as the server . Make the 5500 the server . Below is some info from a cisco webpage.
upported STP Instances
You create an STP instance when you assign an interface to a VLAN. The STP instance is removed when the last interface is moved to another VLAN. You can configure switch and port parameters before an STP instance is created. These parameters are applied when the STP instance is created. You can change all VLANs on a switch by using the stp-list parameter when you enter STP commands through the CLI. For more information, refer to the Catalyst 2900 Series XL and Catalyst 3500 Series XL Command Reference.
The Catalyst 2912 XL, Catalyst 2924 XL, and Catalyst 2924C XL support only 64 STP instances and 64 VLANs. All other Catalyst 2900 XL switches and all Catalyst 3500 XL switches support 64 STP instances and 250 VLANs.
Each VLAN is a separate STP instance. If you have already used up all available STP instances on a switch, adding another VLAN anywhere in the VLAN Trunking Protocol (VTP) domain creates a VLAN that is not running STP on that switch. For example, if 250 VLANs are defined in the VTP domain, you can enable STP on 64 of those VLANs. The remaining VLANs must operate with STP disabled.
You can disable STP on one of the VLANs where it is running, and then enable it on the VLAN where you want it to run. Use the no spanning-tree vlan vlan-id global configuration command to disable STP on a specific VLAN, and use the spanning-tree vlan vlan-id global configuration command to enable STP on the desired VLAN.
For more information about VLANs, see "Configuring VLANs."
