Catalyst 2960 after upgrade
hello,
I have a Catalyst 2960 series switch after upd blocked by the Web console,
I turned on the switch and connected the console cable but it does not reponds, LED Lighted system remains,
I feel that the update process was interrupted because that I was trying to update the others switchs at the same time,and all switch are cascaded,
can you please help me?
Regards,
If you've tried two or three different clients and you can't get anything (not even garbage characters) from console then there's a sure chance the appliance is toast.
Your remedial action would be to raise a TAC Case and get the appliance RMA-ed.

Business catalyst account after upgrading Muse
What happens to my existing Business Catalyst account ($9 version) after I purchase Muse that will include basic hosting? The $9 plan was considered basic at the time I made my purchase. It now seems there is a less expensive plan. My site is currently live.

abhishek raoHi,
Have you checked in the Device Manager to see if all drivers are installed since upgrading? (look for yellow exclamation points)
Uninstall the AMD driver and catalyst control center. Install the version located in the download section of the web support portal for your sleekbook.It will install both driver (intel and AMD) and also switchable graphics capability if it previously existed.
Best regards,

is not recognized any more. reverted back to previous ios with no luckWhat IOS are you running on your Supervisor 2T? As long as it's 15.0(1)SY1 or later you should be OK. (Reference).
If it's not working with that I'd try reload of the ASA SM module (from IOS cli - e.g. "hw-module <module#> reset" and, failing that, "no power-enable module <module#>" followed by "power-enable module <module#>) while the new Supervisor is installed. Watch the log for relevant messages during that process. -

GX70 Can't access Catalyst control after update to MSI Win 8.1 Graphics driver
After upgrading to Win 8.1 (which went fine) I followed the links and installed the latest VGA 8.1 drivers from the MSI website.
Even though the graphics seem to switching appropriately to discreet card for games and integrated for light use, if I try to access either the Catalyst Control Centre or the Configure Switchable graphics. I get a pop-up window that says:
"AMD Catalyst control center can not be started. There are currently no settings that can be configured using AMD Catalyst Control Center"
Any ideas?Never mind
Rolled back to Sept AMD Mobility drivers and all is well again.
FYI... I hadn't noticed but the MSI WIN 8.1 graphics drivers are beta. I don't trust them. -

Cisco Network Assistant MAC search in Catalyst 2960
Hi,
Since I updated a Catalyst 2960 switch to IOS version 12.2(55)SE1 I can't do searchs by MAC address, when I do "Monitor->Search" the following error appears:
"The software version of the selected switch does not support some of the CLI commands in read-only mode for this window. You must have read-write access to this switch to display complete information in this window"
If packets are captured you can see that the issued command by the CNA host is "GET /exec/show/mac-address-table/", the answer from the switch is:
"show mac-address-table
^
% Invalid input detected at '^' marker.
If I do "Configure->Switching->MAC Address" instead I get the mac address-table correctly. In this case the issued command is "GET /exec/show/mac/address-table/dynamic" and no error is displayed, the answer from the switch is the list of mac-address table.I have some site admins that use CNA. I just upgraded their LAN to 3560v2 switches running 12.2(58)SE2 and had them upgrade their CNA software to CNA 5.7(6). They reported the same error.
I think you clearly indentified the problem. At one time the IOS command parser accepted both "show mac-address" and "show mac address". At some point IOS stopped accepting the older "show mac-address" format, and CNA is still issuing this command regardless of the IOS version it is trying to manage. -
Installed wrong image on Cisco Catalyst 2960
some time ago I did an IOS upgrade on the Catalyst 2960, however I used the wrong image and caused the switch CAN NOT load properly. My switch is c2960 but I used c2960s, what a big mistake.
When the switch boots, and it hangs on the execution of the image, because c2960s image will not work on c2960.
Anyone got some idea how I can fix this? I tried to restart the switch and pressed "Break" on the terminal, and it didn't stopped.

Cisco catalyst 2960 booting garbage, help on restore IOS
Dear All,
This is my first time on terminal access of Cisco Catalyst 2960 (2960TC-L), normally would use the web configuration for most task.
Now the switch has an issue with the web interface and when I try to access through terminal, I was greeted with garbage upon the booting of the switch, I searched for the terminal boot process and it wasn't what I was expected for my switch. I was a bit dumbfound now of how can I recover the firmware to its default stage, now that I cannot even boot through its terminal console.
Any help is highly appreciated. Thank you for your time.Hi,
I just verified with my colleague of whom have done quite a few bits before I took over his task.
His reply was he actually did an IOS flash before, though I'm not sure how he did it, but according to him, it was actually a success and the web interface still works for few times before it become like this.
As I tried another time to goes into root mode (or Admin mode??) for the switch, the steps as I performed below:
1. Refer to cisco-2960-putting-setting.jpg for the settings. I press Open and it does display the console Window, no issue there.
2. I hold the "mode" button on the switch and turn on the switch power, and after few seconds the screen display as such (refer to cisco-2960-putty-output2.jpg), the SYST L.E.D. did flash with following pattern: Green (blink ~15 times) then Orange-Green (repeat blink twice) then Green (stable light), for this I was expecting it to goes off after few seconds but it didn't, I wait about a minute before I let go the "mode" button.
3. After I let go the "mode" button, it goes to the screen (refer cisco-2960-putty-output3.jpg), and the SYST still blinking, possibly infinitely... with the console output screen stays like that... and whatever I entered display weird/garbage characters instead, I can't do anything on it.
Each tries display different weird characters, as the SYST still blinking infinitely.
I'm unsure if I'm giving enough details for online troubleshooting, I'll try my best to give as per instructed.
Thank you for your time. -
Long time reader here but first time poster. I am looking into upgrading our network switches soon and I'm trying to decide on a design now. Let me give some background information on the network.
Currently we have a Catalyst 5513 with a Supervisor II, ten 24 port 10/100 cards and a 12 port fiber card installed. There are also two 48 port Alcatel switches that are uplinked to the 5500 as well as six Catalyst 2900XLs (on the factory floor) uplinked to it via fiber. There are about 40 servers and 350clients in total in the building. All servers and most of the clients in the office are connected directly to the 5513. We will be consolidating buildings soon and plan on adding another 200 devices to the network (office and factory floor area).
I was thinking we should get two Catalyst 3750G-48TS and a 3750G-12S in a stack for the core switch. Then use Catalyst 2960-48TC-L switches uplinked to the 3570 stack for the access layer. Does this make more sense than directly connecting all the clients and servers directly to the 3570 stack? What would be the advantages/disadvantages of each setup besides cost?
Thanks for any help you can provide!I tend to go with a more modular approach and hang nothing off my core except otehr switches. Put your servers on their own switches as well. There are a few reason i do it this way.
The first is I run two cores for redunacy. by giving servers their own access layer switch, i can isolate them from a core failure.
Second, ports on a core switch tend to be more expensive. I know I'm going to be adding servers in the next few years. Its cheaper for me to buy more 3560's then more blades for a 6500.
Third, modularity. I can make more changes to either the core, or edge switches and not effect the other. Say you find out down the road, that the 3750 stack isnt quite moving the number of packets you need. If you plug end users and servers into your core now, just picture how much of a bear it will be to replace the core. Always try to go the route that will give you maximum flexibility and growth. -
Moving VLAN config from catalyst 2960 to SG300
Dear all,
my existing catalyst 2960 config for vlans:
interface FastEthernet0/2
description 3Com Switch
switchport access vlan 10
switchport mode access
interface FastEthernet0/5
description to Cyberoam
switchport mode trunk
interface FastEthernet0/18
switchport access vlan 40
switchport mode access
interface FastEthernet0/19
interface FastEthernet0/20
switchport access vlan 20
switchport mode access

interface Vlan1
no ip address
no ip route-cache
interface Vlan10
ip address 192.168.0.51 255.255.255.0
no ip route-cache
Inside trunk there are VLAN10 (native), VLAN20,30,40
now, when I try to configure the same on SG300 I get trunk issues - no VLAN10 (native) inside trunk.
Regards
GNHi Mlechte, I cheated on your question a bit. I have used two SG300-52 switches. I am able to accomplish what you're asking with these models.
On my master switch the configuration fundamental is simple. For argument sake, I disabled all CDP. I create vlan 100 for voice. Assigned my voice vlan 100. I enabled LLDP on every port. I enabled every optional TLV on every individual port.
I then connected a 100% factory default SG300-52 to the 'master switch'. After about 3 minutes the VSDP created the voice vlan, the link between switches became 1u, 100t. The vlan database populated the vlan 100 and everything just worked nicely.
So, to answer your inquiry, if your 2960 supports the same TLVs it should work okay.
I do recommend you use the SX300 series, it is a much more robust switch, supports full CLI and has a lot better feature set. A SG300-08 (srw2008-k9-na) is around $250. The SG200-08 is about a $100 cheaper. The difference between models is astronomical and a much better investment.
Please review
console_log_master <--This is the switch that will advertise to the downstream
console_log_receive <-- This is a default switch that received the LLDP information

Hi,
I've been advised by a third party vendor to put my catalyst 2960 poe switch into consumption mode. Is that possible with this model?
Thanks,This is what you can do:
Supported Protocols and Standards
The switch uses these protocols and standards to support PoE:
•CDP with power consumption—The powered device notifies the switch of the amount of power it is consuming. The switch does not reply to the power-consumption messages. The switch can only supply power to or remove power from the PoE port.
•Cisco intelligent power management—The powered device and the switch negotiate through power-negotiation CDP messages for an agreed power-consumption level. The negotiation allows a high-power Cisco powered device, which consumes more than 7 W, to operate at its highest power mode. The powered device first boots up in low-power mode, consumes less than 7 W, and negotiates to obtain enough power to operate in high-power mode. The device changes to high-power mode only when it receives confirmation from the switch.
High-power devices can operate in low-power mode on switches that do not support power-negotiation CDP.
Cisco intelligent power management is backward-compatible with CDP with power consumption; the switch responds according to the CDP message that it receives. CDP is not supported on third-party powered devices; therefore, the switch uses the IEEE classification to determine the power usage of the device.
•IEEE 802.3af—The major features of this standard are powered-device discovery, power administration, disconnect detection, and optional powered-device power classification. For more information, see the standard.
•IEEE 802.3at (Catalyst 2960-S only)—This PoE+ standard supports all the features of 802.1af and increases the maximum power available on each PoE port from 15.4 W to 30 W.
Powered-Device Detection and Initial Power Allocation
The switch detects a Cisco pre-standard or an IEEE-compliant powered device when the PoE-capable port is in the no-shutdown state, PoE is enabled (the default), and the connected device is not being powered by an AC adaptor.
After device detection, the switch determines the device power requirements based on its type:
•A Cisco pre-standard powered device does not provide its power requirement when the switch detects it, so a Catalyst 2960 switch allocates 15.4 W as the initial allocation for power budgeting; a Catalyst 2960-S switch allocates 30 W (PoE+).
The initial power allocation is the maximum amount of power that a powered device requires. The switch initially allocates this amount of power when it detects and powers the powered device. As the switch receives CDP messages from the powered device and as the powered device negotiates power levels with the switch through CDP power-negotiation messages, the initial power allocation might be adjusted.
•The switch classifies the detected IEEE device within a power consumption class. Based on the available power in the power budget, the switch determines if a port can be powered. Table 12-1 lists these levels.
Table 12-1 IEEE Power Classifications

Dear all,
I'm currently in the process of configuring two Nexus 5672 Switches for our Network. I connected one of the switches to our catalyst 3750 Core using trunks on each side. Everything worked just fine - the link came up and I was able to manage the Nexus using the SVI I created in VLAN1.
However, after upgrading the Nexus 5672 from NX-OS 7.0(2)N1(1) to 7.1(0)N1(1), the connection between the Nexus and the Catalyst 3750 is broken - the corresponding port on the Nexus (eth 1/1) is blocked by STP due to a Port VLAN ID mismatch and it chooses itself to be the root bridge:

I've also read through the Release Notes for NX-OS 7.1(0)N1(1) and haven't found anything that sounds suspicous. Do you think this might be a bug or could it also be another problem?
Thanks
MichaelThank you - an additional indication that this is a bug indeed. I'm trying 7.1(0)N1(1a) today, if it doesn't work either I'll downgrade to NX-OS Release 7.NX-OS Release 7.0(5)N1(1a) which is the recommend Version to use anyway. I'll post the results here.
I'll also check with our distributor how we can inform Cisco about a potential bug.
