Can't see Catalyst 2960 48TT

I had to connect a new Catalyst 2960 48TT switch to my Network. Which is connected straight to port two in Catalyst 3750G 48+4. I have three other already connected: 2 x Catalyst 2960 48TT and 1 Catalyst 2960 48TC.
The problem is I can not see the newly connected switch in Cisco Network Assistant. I see the other two switches but not the new one.
I have couple of computers connected to the new switch which are working fine.
I changed the main cables which go from 3750G to the other switches.
The network is working fine, the connected compuetrs have internet...
Can someone please help...?

Can not administer Catalyst 2960 switch via console

Hello,
I want to configure my switch via console cable, the switch boots up normally, and there are no configurations present on the switch. However, anything I type does not appear on the terminal client. I used several terminal clients (TeraTerm, PuTTY, HyperTerminal), all latest versions as well as different PCs. I even forced the switch to rommon mode, still, anything I type does not appear on the terminal client.
Here's the output of TeraTerm:

Can't upgrade Catalyst 2960S-48LPS-L to 15.0.2X

I just purchased a new 2960S-48LPS-L. I can't upgrade it past 15.0.1-SE3. If I try to go any newer with the firmware it gives a licensing error. Then it boots into a cut mode of the IOS. Below is a copy of the licensing error after it boots to a newer IOS. The same error also appears in the switch log.

The switch does load the 15.0(2)SE6 and comes up to that prompt showing that there is no valid lanbase license. At that point it comes up to a cut version of the IOS it only shows a couple of enable and configuration commands (not the full list). It won't let me save the running configuration, it also won't let me reboot the switch through the reload command. Due to it not being able to access the startup-config. The switch works perfectly running IOS 15.0(1)SE3 and below.
It gives the below errors while running IOS 15.0(2) and newer:

Troubleshooting Fiber Connection on a Catalyst 2960

I am trying to test my fiber connectivity on a Catalyst 2960 before I deploy it. So what I thought I would do is connect it to another switch in my office with a open port for the fiber connection. The other switch is a Catalyst 3560G. Here are the port configurations:
interface GigabitEthernet0/2
switchport trunk allowed vlan 1,100
switchport mode trunk
macro description cisco-switch
interface GigabitEthernet0/25
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 1,100
switchport mode trunk
The first one is the catalyst 2960 and the 3560G is the second.
When you show the interface for each of these it shows that it recognizes the media but the line protocal and the GigbitEthernet Port is down.
Any Ideas?

Sorry... a fiber optic cable with a connector on each end.
To aid in troubleshooting, many times we loopback the signal back to the originating device. An optical loopback is just connecting the transmit (Tx) to the receive (Rx).
The multimode SFP/GBIC transceiver you are using will allow you to directly connect the Transmit and Receive ports without damage to the unit. This should provide you with a green link LED.
If so, then you can reconnect your fibers and loopback (connect the two fibers together) at the far end of the fiber link (use an optical adapter) and see if you get a green LED.

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.

Cisco SG300-28 / SGE2000 / Catalyst 2960

Hello everyone,
I'm looking for switch to accompany Cisco ASA 5520 in data center, with 20+ GE ports and no need for PoE.
I would like to understand the difference between Cisco SG300-28, Cisco SGE2000 and Cisco Catalyst 2960, 2960-C and 2960-S Series (except specific number of ports). As far as I can see the Cisco SGE2000 has 4x SFP and is stackable unlike the SG300 with 2x miniGBIC/SFP, but not much else. Cisco Catalyst 2960 series offers some additional features like USB storage, but I can't imagine I will need that.
Any suggestions?
Thank you
Dan

I recieve and error .
SNMPv2-SMI::mib-2.17.2.15.1.3 = No Such Instance currently exists at this OID
For the sake of comparison, querying our 4700 :
snmpwalk -v 2c -c bic-zua-ro 10.u.y.x 1.3.6.1.2.1.17.2.15.1.3
returns (as expected, cropped)

SNMPv2-SMI::mib-2.17.2.15.1.3.3 = INTEGER: 5

SNMPv2-SMI::mib-2.17.2.15.1.3.259 = INTEGER: 5
Is there some special configuration i need to do on our 2960's. The only snmp related settings i can see in the running config is snmp-server community. In this case :
snmp-server community bic-zua-ro RO
Thanks in advance for any comments/ assistance.

Hi Vinod,
Wow, thanks for your prompt reply. Output from filtered running config pasted below
TVS-Stack17#sh run | inclu snmp
snmp-server community bic-zua-ro RO
Interestingly when i walk the entire dot1dBridge (1.3.6.1.2.1.17) i recieve lots of data from both dot1dBase (1) and dot1dTp (4) but nothing from dot1dStp (2)
I tried portAdditionalOperStatus and did not recieve any response but got lots of data from its patent portEntry (1)
Running show spann on the 2960 stack i can see various ports in forwarding and blocking start as i would expect.
Rgds,
Ian

Catalyst 2960 POE Consumption

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
Class
Maximum Power Level Required from the Switch
0 (class status unknown)
15.4 W
1
4 W
2
7 W
3
15.4 W
4
30 W (Catalyst 2960-S only)

Catalyst 2960 - IBM/Cisco IGESM - Trunk port configuration

Good day all!
I am new in Cisco world and try to configure a trunk between a Catalyst 2960 switch and a IBM Blade Center IGESM switch (manifactured by Cisco).
Unfortunately, it seems that the network traffic doesn't cross the trunk link.
I have followed (at least, I think so) the instructions given on the different Cisco documentation papers but I can't find the mistake in my configuration (lack of experience :-( !).
Both switches are using IOS. 2960 uses IOS 12.2(25)FX and IGESM uses IOS 12.2(22)EA8.
The ports are connected through a cross-over cable Cat5e.
Please find below the configuration for each ports:
Catalyst 2960:
Name: Gi0/1
Switchport: Enabled
Administrative Mode: trunk
Operational Mode: trunk
Administrative Trunking Encapsulation: dot1q
Operational Trunking Encapsulation: dot1q

Unknown unicast blocked: disabled
Unknown multicast blocked: disabled
Appliance trust: none
For my test, I try to ping a blade (connected to IGESM) in VLAN 200 from a workstation connected to Catalyst 2960 (in VLAN 200 too). From a network anaylser (ethereal), I can see the ARP broadcast from each side but none are going across the trunk link.
I am a bit lost about this problem and would be grateful for any assistance in solving it!
Many, many thanks in advance for your time!
Best regards,
Fabian

Hi Glen!
Both switches (Catalyst 2960 & IGESM) are brand new and most ports are still reflecting manufacturer's default configuration. Vlan 2 is the default native vlan for IGESM ports (excluding ports used for switch management which use vlan 1 as most Cisco switches).
I changed the native vlan for g0/5 on IGESM to 200. Now, ports g0/5 (access mode) and g0/20 (trunk mode) are on native vlan 200. On g0/5 is installed Windows 2003 instance (firewall disabled). The only purpose is to receive and send ping request to test connectivity.
My workstation is connected to 2960 switch on port fa0/1 (please find the configuration below). I can successfully ping other vlan 200 machines connected on the same switch. For testing purpose, I try to ping the blade machine connected on port g0/5 on IGESM.
Configuration of fa0/1:
Name: Fa0/1
Switchport: Enabled
Administrative Mode: dynamic auto
Operational Mode: static access
Administrative Trunking Encapsulation: dot1q
Operational Trunking Encapsulation: native
Negotiation of Trunking: On
Access Mode VLAN: 200 (Workstation VLAN)
Trunking Native Mode VLAN: 200 (Workstation VLAN)
Administrative Native VLAN tagging: enabled
Voice VLAN: none
Administrative private-vlan host-association: none
Administrative private-vlan mapping: none
Administrative private-vlan trunk native VLAN: none
Administrative private-vlan trunk Native VLAN tagging: enabled
Administrative private-vlan trunk encapsulation: dot1q
Administrative private-vlan trunk normal VLANs: none
Administrative private-vlan trunk private VLANs: none
Operational private-vlan: none
Trunking VLANs Enabled: ALL
Pruning VLANs Enabled: 2-1001
Capture Mode Disabled
Capture VLANs Allowed: ALL
Protected: false
Unknown unicast blocked: disabled
Unknown multicast blocked: disabled
Appliance trust: none
Is there any other information I could provide to better help you to understand the configuration?
Cheers!
Fabian

Help! I Can't See My Web Page!

Good evening fellow Dreamweaver users,
    I recently tried centering one of my web pages using a code that I received from Nadia for another one of my pages. The code worked for that page, but when I entered it into my second page it didn't work. I deleted the code from my second page, but now I can't see it when I go to test it in my browser. All I see is a blank white page. I'm in dire need of some help. Yes, I am an amateur and I'm sorry if my questions are bothering some of you. However, I'm trying to learn this stuff, but I get confused on where and how to place the coding and now I have messed up and don't know what to do to fix it. I would appreciate it if someone could help me get my page to be auto-centered and show up again when I test it in my browser. Below is the current coding for my page. Thank you.

              <br>
              In 1996 I enlisted into the U.S. Army's delayed entry program. In 1997 I graduated high school and left Oakdale to go to my first duty station after I finished my military occupation specialty training. The military has allowed me to see other parts of this country and world, which enhanced my "out of the box" way of thinking. The military also helped enforce the great skills and values that I had learned growing up in a family full of military service members (i.e. discipline, teamwork, and professionalism). In the military my occupation specialty was an Infantry Team Leader, which is highly demanding both physically and mentally. Although the nature of my job in the military took a lot of intelligence the physical demands of the job was the dominant attribute. After ten years of honorable service my body could no longer take the physical demand of being an Infantry soldier. In 2007 I was given an honorable disability discharge from the military. This was the catalyst that got me started on the path of pursuing a career that would allow me to utilize my creative thinking skills, as well as the skills and attributes I developed through my years in the military.<br>
              <br>
              During my exploration in higher education in 2007 at San Joaquin Delta College I came across their Graphic Arts Program. I instantly fell in love and have not turned back. I feel fortunate and blessed to have found myself on a career path towards becoming a Graphic Designer. My strongest skill set is my creative "out of the box" thinking skills and this type of media allows me to not only bring my ideas to life, but the ideas of others. I couldn't ask for a better career for myself than having a career that is both challenging and constantly evolving.</span><br>

Good morning Nadia,
    I apologize for it taking me so long to respond back to you, but I have been quite busy with trying to prepare for my Fall semester college transfer. After copying and pasting your revised code I still couldn't see my page when I viewed it through my browser. However, the code for centering the page worked in Dreamweaver, so I decided to start over by using the code you gave me to center the page as a template. After achieving this enormous task I now have a centered web page that is viewable in my browser. I want to let you know that I'm very appreciative and thankful for your help, as I was really stuck in a bad spot. Even though I have taken a web design course and have read a few books I still find myself having trouble with fully understanding how to correctly implement the coding in Dreamweaver, which I feel is a key part in becoming a great web designer. I have pasted the new code for the page below in case you wanted to check it out.

I really enjoy coming up with creative ideas and then bringing those ideas to life using many different types of media. <br />
                    <br />
          In 1996 I enlisted into the U.S. Army's delayed entry program. In 1997 I graduated high school and left Oakdale to go to my first duty station after I finished my military occupation specialty training. The military has allowed me to see other parts of this country and world, which enhanced my "out of the box" way of thinking. The military also helped enforce the great skills and values that I had learned growing up in a family full of military service members (i.e. discipline, teamwork, and professionalism). In the military my occupation specialty was an Infantry Team Leader, which is highly demanding both physically and mentally. Although the nature of my job in the military took a lot of intelligence the physical demands of the job was the dominant attribute. After ten years of honorable service my body could no longer take the physical demand of being an Infantry soldier. In 2007 I was given an honorable disability discharge from the military. This was the catalyst that started me on the path of pursuing a career that would allow me to utilize my creative thinking skills, as well as the skills and attributes I developed through my years in the military.<br />
          <br />
          During my exploration in higher education in 2007 at Delta College I came across their Graphic Arts Program. I instantly fell in love and have not turned back. I feel fortunate and blessed to have found myself on a career path towards becoming a Graphic Designer. My strongest skill set is my creative "out of the box" thinking skills. Being a Graphic Designer allows me to not only bring my ideas to life, but the ideas of others. I couldn't ask for a better career for myself than having a career that is both challenging and constantly evolving.</span><br />

Catalyst 2960 SF Stacking

Hi
I am stacking 6 Catalyst 2960 SF Series PoE 48 ports, I am using the Bladestack cable. I plug it in from 1 to 2 on all the switches. If I look at the lights it shows 4 in on group and 2 in another. If I do a show switch detail it shows the following
Switch/Stack Mac Address : 44ad.d982.a100

Hi , i think only four 2960 SF switches can be stacked into a singe logical switch.
Please refer the link , hope this helps:

Catalyst 2960 Problem with Cisco SPA512

Hi there,
I hope someone can help me.
I don't have much experience with switches, I'm doing the desktop support in our company.
We have Catalyst 4510 R+E to 2 Catalyst 2960 switches and seperate VLAN's for IP Phones and for Internet in one part of our office.
Now I'm running into trouble with some IP Phones that are connected to the 2960 switches. It appears only to happen with Cisco's SPA-512. I've tried FW 7.5.2, 7.5.5 and 7.5.5b. These phones sporadically drop the call / connection, with the red MIC button blinking. Based on my research this means that it looses Internet connection. I have 1 SPA512 with FW 7.5.1 that does not show these symptoms.
I have other phones SPA942 and Polycom IP335 in the same area behind the same switches and no issues.
We've tried to disable auto negotiate and set a fixed transmition rate or either 1Gbps and 100Mbps, both without success.
I also have SPA512 in other areas of the office just connected to our Catalyst 4510 R+E and they work just fine. That's why I don't believe it has anything to do with the 4510, but I can be wrong.
That's all I have for you guys. Hope someone can help me to fix / troubleshoot this..
Frank

Gbic loop on catalyst 2960

Hello,
I would like to know if there is a way to validate that a SFP type 1000baseLX is working properly on catalyst 2960.
I am looking for the loop feature that is available on routers.... but not on switches.
The topology is 2 catalyst 2960 switches with both SFP type 1000baseLX connected together with a fiber. This was working find but actually, the two interfaces are down/down.
The idea is to be sure that the problem is on the fiber and not on one of the SFP....
Thank You for your help.

UniDirectional Link Detection (UDLD) addresses your concern regarding the fiber. See http://www.cisco.com/en/US/docs/switches/lan/catalyst2960/software/release/12.2_46_se/configuration/guide/swudld.html for more information.
For the SFPs themselves, you might want to review http://www.cisco.com/en/US/products/hw/modules/ps4999/products_tech_note09186a00807a30d6.shtml for more information.
Hope this helps.

Problem with Cisco Catalyst 2960

I've got a problem with the Catalyst 2960 / 24TCL switch. The Flash-directory was empty. After I copy with xmodem the firmware bin-file into the flash-directory and installed it .. I miss the HTML-Directory. Can somebody tell me how I can get it back?
