My question:
Is it possible to prohibit the passage of MAC address on port 7 vlan?
Already available conf Notices prohibits the passage of MAC address per port for any vlan.

Just a couple of options might work , you could setup private vlans and isolate the ports so they can only comminucate with what you allow or try a PACL or VACL if your software supports it

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.

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

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.

SNMP, Query dot1dStpPortState on Catalyst 2960-S

Hi Community,
I would like to be able to query the dot1dStpPortState obect on the Catalyst 2960-S on our LAN . Im running firmware
c2960s-universalk9-mz.122-55.SE2.bin and according to the Cisco SNMP Object Navigator the object is supported (via the BRIDGE-MIB).
However when i query using snmpwalk from my workstation :
snmpwalk -v 2c -c bic-zua-ro 10.u.y.x 1.3.6.1.2.1.17.2.15.1.3
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)

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.

2960 - mac-auth-bypass

Hello,
we want to use standalone mac authentication bypass (with freeradius).
Yesterday we tested it with a catalyst 3750 IOS 12.2(35) and it was working fine! The config on an interface looked like that:
(config-if)switchport mode access
(config-if)authentication port-control auto
(config-if)mab
(config-if)spanning-tree portfast
Today we tried to do the same with a catalyst 2960 IOS 12.2(44). I want to configure the interface like on the 3750, but I can't.
Everytime I write the command "dot1x mac-auth-bypass" (I think this is the correspondent command to "mab") the switch automatically configures "dot1x pae authenticator" and "dot1x violation-mode protect" on the interface. So it looks like that:
interface GigabitEthernet0/1
switchport mode access
dot1x mac-auth-bypass
dot1x pae authenticator
dot1x port-control auto
dot1x violation-mode restrict
spanning-tree portfast
If I configure "no dot1x violation-mode protect" the switch accepts the command, but it don't removes the entry from the interface.
If I configure "no dot1x pae authenticator" the switch removes the whole config from the interface except "switchport mode access" and "spanning-tree...".
I don't understand what the problem is?! Is it not possible to use mac authentication bypass without dot1x (-> pae command) and violation-mode in this IOS version???
The violation-mode avoids the contact to the radius server. :-(
Thank you for your help.
Greetings Lydia

Hey,
1. Does somebody know if you can use standalone MAB with dot1x guest vlan?
I tried it and the guest vlan was not set. Is it required to configure dot1x with the shortest timeout, so that MAB is starting fast and if it fails, there is the guest vlan.
2. In the config guide there is a sample configuration for standalone MAB. I'm wondering why they configure "switchport access vlan 40"??? In what situation does this takes affect? Is it like the guest vlan? So, if mab fails, the port is configured with vlan 40???
interface FastEthernet2/48
switchport access vlan 40
switchport mode access
authentication port-control auto
mab
spanning-tree portfast
spanning-tree bpduguard enable
Greetings Lydia

Catalyst 2960 for my LAN WS-c2960-48TC-S vs WS-c2960-48TC-L

Hello
I want buy a Catalyst 2960 but i don't now which is great for my situation.
Model : WS-c2960-48TC-S (LAN Lite - 400 euro) vs WS-c2960-48TC-L (LAN Base - 900 euro) the difference of price is half.
I need 3 VLAN (2 VLANs with data and other VLAN (3th only voice).All security options want applied on ports.(MAC,ACCESS..etc)
Between switch and router will be a TRUNK channel...
The network design parts: lan printers - 4, desktop - 16, phone IP - 10.
I have only ISP .
So..what i need? LAN Lite or LAN Base
Another question: In LAN Lite i have all commands?
thank's

Q. What are the advantages of Cisco Catalyst 2960 Series Switches with the LAN Base software relative to Cisco Catalyst 2960 Series Switches with the LAN Lite software?
A. Cisco Catalyst 2960 LAN Base switches deliver intelligent services for branch offices and wiring closets. The LAN Base IOS software supports enhanced Layer 2+ security, quality of service (QoS), availability, and scalable management to enable new converged applications. Catalyst 2960 LAN Base switches include both 10/100 Fast Ethernet and 10/100/1000 Gigabit Ethernet connectivity in 8-, 24-, and 48-port configurations.
Cisco Catalyst 2960 LAN Lite switches are for entry-level branch office and wiring closet networks. They simplify the migration from nonintelligent hubs and unmanaged switches to a fully scalable and reliable network. The LAN Lite IOS software supports standard Layer 2 security, QoS, and availability while lowering the network total cost of ownership. Catalyst 2960 LAN Lite switches deliver 10/100 Fast Ethernet connectivity in 24- and 48-port configurations.
All Cisco Catalyst 2960 Series Switches have technical support service options available through Cisco SMARTNet ® service. All come with a Limited Lifetime Hardware Warranty, and LAN Base and LAN Lite software updates are provided at no additional cost.
Information came from the below link:
http://www.cisco.com/c/en/us/products/collateral/switches/catalyst-2960-series-switches/prod_qas0900aecd80322c37.html
Will all commands be available? No...if they were then what would be the point of having different software levels? Will the switch meet all basic to intermediate needs? Yes. If you are looking for a set of specific commands to see if they are available then check out the command reference tools available from Cisco.

Deskjet 3050 J610 Wireless Setup Problem - Thinks I'm using MAC filtering

I just got an HP Deskjet 3050 J610 from my parents, who have never used it. The ink cartridges were still in their wrappers. Trying to set it up tonight, and everything was going well until I tried connecting it to the wireless network.
My router does not have WPS, so I'm having to do this via USB. The software is able to detect my router's SSID, encryption type, and password. However, when trying to connect the printer to the router, it fails. The Wireless Network Test Report claims that it might be because of MAC address filtering. I double checked my router settings, and I am NOT using MAC filtering at all. I have not yet tried rebooting everything (Printer, laptop, router), but I am doubtful that will resolve the issue. For security reasons, I would prefer not to say what security I'm using, but I will say that it IS supported by the printer.
I'm using Windows 7 on an Asus laptop, and my ISP is Verizon Fios.

Hi Manjunath, I spent the last hour on that site. Everything I found was about how to add the printer's MAC address to the router's filter settings. But I repeat, I am NOT using MAC filtering on my router, but the printer thinks I am.
Or rather... THOUGHT I was.
Rebooting the printer and the router helped. Of course, I did both at the same time, so I'm not sure which one was required, or both, but the long and the short of it is, it works now.

HP Deskjet 3050A ALL-IN-ONE J611 series ---- mac filtering problem

i have a HP Deskjet 3050A ALL-IN-ONE J611 and i cannot get my printer to connect wireless. Everytime I try to connect it it always tells me an error. The error says:
Issue: MAC address filtering may be enabled on your wireless router.
Solution: If MAC address filtering is enabled on your router you should disable it.
The thing is i checked my router to make sure the MAC filtering was not enabled and it wasn't. So why does my printer keep telling me this? if i can get passed this problem i think it would connect. The MAC address is already stored in the router.

E1200 - Ports not working and mac filtering problem

If there was a way to give negative stars to this router, I would. As it is, the minimum rating I can give this product is one star, and that's one star too many.
I was upgrading from the WRT54G, which is an ugly thing to look at, but a reliable workhorse nonetheless. I turned that in to a downstream switch in my comms hub.
On the E1200, I flashed the latest firmware, used different Cat5 cables, and different laptops before committing to hating this product.
The first time I reached out to Amazon, the Amazon rep gave me a Cisco number to call. Turns out, that's some shady mortgage refinance hotline. Try it for yourself! 1-800-666-1771.
Now, the rant -
1. Two out of four wired LAN ports don't work: What can be the fix for this?! The activity lights on ports 3 and 4 blink and suggest data transfer is taking place, but the wired laptop simply can't acquire an IP address and access the internet. Same result when I connect my Panasonic Blu-Ray player to ports 3 and 4. None of the Viera Cast features load.
2. MAC filtering unreliable: The wireless routing works somewhat reliably, if and only if, one settles for the most basic security. If I only choose a password and WPA2 protocol, things work fine. If I add another layer of security (in my case, enabling MAC filtering and only PERMITTING gateway to listed MAC IDs), things break down. As soon as I disable MAC filtering, wireless access to authenticated clients is restored.
3. Cisco customer service: The censored world we live in, compels me to criticize politely. TERRIBLE. Cisco website is unintuitive, and frustrating. There's no easy way to register your purchased product. The Cisco "registration" is intentionally misleading and deceptive. For all intents and purposes, it's just an information gathering tool for Cisco. Don't bother registering there, unless you love the idea of storing your personal information on their servers. Their phone-based customer service is apathetic and uninterested. My rep was so distrusting of my intelligence and motor control, that he simply wouldn't believe that I had selected "PERMIT" and not "PREVENT" as the option under MAC filtering. After he asked me the same question for the fourth time, I raised my voice, and he gave up the idea of checking for the fifth time.
However, this review is a tale of two companies. I reached out to Amazon again. This time, I got a rockstar in the shape of Leanne C! She was incredibly helpful, and understanding. What's more, she set up my return without any hassle and this Cisco dud is on its way back. I'm a big fan of Leanne's and my confidence in Amazon is restored.
I'm sure that i received a lemon. I've never had problems with Linksys products. Maybe others' experience is different from mine.

In your case as port numbers 1 and 2 does not work, what you could have done a loop back test. To perform a loop back test you need to take an ethernet cable, connect one end of that cable to internet port and the other end to the non-working port on the router. If you get the led to glow on both internet and the respective ethernet port that indicates that the port is working fine.
It could also be a sychronization issue between the above mentioned lan ports and the lan card of your computer. As a part of trouble shooting you can try to reduce the card speed of your lan card. Following are the steps to reduce the speed of your lan card.
START--> right-click My Network Places and click Properties
right-click on the device manager and click properties
Click on the CONFIGURE button
Select the ADVANCED tab and in the box under the header property select "speed and duplex" and change the value on the right to 10 mbps half duplex. A restart would be recommended after performing these steps.
In the second half you said that after enabling the mac filter option the internet breaks down. Here, do you mean to say that the computer
gets disconnected from the wireless network or it stays connected with a valid IP address but without an internet connection.
Well, it is an unusual issue however you could have reset and reconfigure the router as you got the latest firmware upgraded on it.
Steps to reset the router:
Push the reset button on router for 30 seconds, turn off the router wait for 30 seconds and then power it on. Power light should blink when you perform the reset process.

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.

Bandwidth monitoring on a Catalyst 2960

Hello all, I'm working with two Catalyst 2960 switches and I would like to know if there is a way to monitor bandwidth on individual ports. Ideally I would like to have one graph showing a bandwidth usage reading on each port. I tried using the Network Assistant to accomplish this, but I was only able to view one port at a time. I also tried using a traffic graphing program from Paessler, but a MIB file is needed to allow the program to connect to the switch. When I ran a search on the network management page the 2960 was not on the list for MIB supported products. Is this type of graph possible to do? Or is there a more effective way to accomplish what I would like to do. Any ideas or suggestions would be helpful.

Hi, we have just swapped all our avaya switches with catalyst 2960 (12, 24 and 48 ports) and 3750 (48 ports with 10gig module).
How do I find what port I should monitor for bandwith graphs?

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..

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.
