IOS for 2960 switch

How i can download IOS for 2960 switch...?

No. I have not Service contact?
A valid Cisco Service Contract is needed to download IOS from Cisco website. You may need to talk to your authorized Cisco reseller or the vendor who sold you the switch.

IS Prime DCNM support for 2960 switches

Hi All,
There is a requirement for a NMS solution, Solution must have a single dashboard
but in the netwroks i am having 2960s, N2K, N5K, N7K, in order to mange this data-center network
do I need to quoted for Cisco LMS and DCNM or LMS is enough

The most comprehensive single product solution for those set of devices would be LMS. It does have limitations in managing the User Tracking, VLAN (provisioning primarily) and SAN aspects of the data center switches. Note Nexus 2ks are not separately managed, but rather viewed as an integral part of their controlling 7k or 5k.
LMS Catalyst 2960 support described here.
LMS Nexus support described here.
DCNM is not really designed for IOS-based devices. It has some very limited support for the Catalyst 6500 but other than that it is primarily focued on the NX-OS-based data center products. See the DCNM Release Compatibility Matrix for more details. (And add the DCNM 6.1 release notes updates.)

Increasing TFTP block size for 2960 series switches

I have read that some Cisco components can increase the default TFTP block size to values greater than 512 bytes by using the command -
ip tftp blocksize xxxx
This doesn't seem to be available on Cisco 2960 series switches. Is there a way to do this with the 2960's?

I have moved a WS-C2960-24LC-S running LanLite to 12.2(55)SE9 - the current end of the line for this switch - and indeed the command is not present. Sooo....this appears to be a limitation of LanLite.
My predecessor implemented about 70 switches with LanLite. I put a stop to this about a year ago but it is going to take some time to flush them out of the inventory.
Thanks for your response.

Glad to help, Don! Just came across the following site that offered a working combo. Might need to doublecheck the code's compatibility with the two types of line cards you have though:

Configure a different DHCP pool on a 1921 Router for a VLAN 2960 switch

Hello guys,
I have a cisco 1921 router with the LAN interface connected to a Cisco 2960 switch.
My 2960 switch is configured to work in VLANs
What I would like to do is create IP pools for each VLAN in my switch.
This will allow a PC on a VLAN to get an IP in a different subnet as PCs connected in other VLANs
thanks!
Martin

Hello, Please see Cisco documentation: Upgrading Software Images on Catalyst 4000/4500 Series Switches

Edited: Please be aware that several recent releases of the 4500 code ignores the startup config and goes to ROMMON once you have upgraded, fix this by sorting the configreg.

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:

After the last line, I can not type any command at all. I encountered this on three 2960 switches that we have here in our laboratory. Can anybody help me on how I can get access to the switch via console?
Thanks in advance.

Cisco 2960s Switch replacement

Greetings,
Dear Experts,
We are using the Cisco 2960s Switches in our network. We have two failed switches and asked for replacement from our supplier. They informed that the 2960s model is approaching End Of Service (EOS) and the replacement of that model are as below:
1- WS-C2960X-24TS-L
Catalyst 2960-X 24 GigE, 4 x 1G SFP, LAN Base
2-WS-C2960S-24TS-L
Catalyst 2960S 24 GigE, 4 x SFP LAN Base
What is the best practice to make my decision of which to select? will it make difference from the configuration perspective? is there a possibility for conflict with the existing 2960s Switches?
Many thanks in advance for your kind assistance.
Thanks and Regards

We have two failed switches and asked for replacement from our supplier.
Time for you to talk to your supplier. Cisco has announced the EoS/EoL for the 2960S back in November 2014 (End-of-Sale and End-of-Life Announcement for the Cisco Catalyst 2960-S Series and 2960-SF Series Switches). However, this only means the date of November 2014 is just a date of announcement. The final date of sale for the 2960S is November 2015.
I think your supplier either is getting confused (didn't read the announcement properly or didn't know) or is just looking for ways to make more money.
is there a possibility for conflict with the existing 2960s Switches?
You can form a stack of 2960S and 2960X. Just know the limitations, and they are:
1. The entire stack must have the same IOS versions;
2. The stack speed will drop from 20 Gbps (2960X) to 10 Gbps because 2960S has been set to run only at this speed; and
3. You cannot have five or more in a stack if you have a 2960S as a member of the stack.

Etherchannel between 2960 switches

Hello All,
I configured etherchannel between two 2960 switches.
Both the switches have SVI with subnet 192.168.2.3 and 192.168.2.4
I have another vlan3 on one of the switch.
so when i created etherchannel between two Gig ports and allowed both the vlans,it gave me an error messg,
Nov 3 12:41:07.332 KSA: %EC-5-CANNOT_BUNDLE2: Gi1/0/19 is not compatible with Gi1/0/20 and will be suspended (vlan mask is different)

May i know why....
Thanks

Hello Mudasir
This will be a problem of allowed vlan mismatch. All the interfaces which are going to add in the etherchannel must have same allowed vlan on both sides.
You can check for the allowed vlan on all the interfaces as well as on Port-channel.
You can see the below forum having the same problem:

Calculate? Calculate for wirespeed/line-rate? If the latter, take all the port bandwidths, and assuming they are duplex, double for necessary fabric bandwidth. I.e. 48 gig ports would need a 96 Gbps fabric. Take all your port bandwidths, and allow 1.448 Mpps per gig (for minimum size Ethernet packets), i.e. 48 gig ports would need 69.5 Mpps. Once you have required fabric bandwidth and PPS, you can compare to vendor's specs.

Connecting 2 3750 Switches in Stack with 2 2960 switches in full Mesh

Hi Friends,
I have attached a pics which DC design of one of our customer , as network engineer i have design this , so i am responsible for implementing it, now request you all to kindly guide me what would be technical problem i have to face in achieving this and how can i over come .Please be in detail. Waiting for your response .
Regards
Amit Kulshrestha

I have attached modified diagram , please suggest.
The major issue I see is that you have not mentioned whether the 2960's are stacked? For the design to work, they need to be stacked because you cannot create port-channels between them and the Core switches unless then 2960's are stacked.
==> You are right , surely 2960 Switch need to be in stack form.
Personally I would look at more powerful switches than the 2960's, something along the lines of the 3750x range or probably now the 3850's.
==> This is constrain of customer, not our responsibility.
The second issue I see is that your servers are connected to the WAN switches. Is there a reason for this? Usually they would be connected to the core switches.
==> For this If 1 separate 2960 series switch can be used ?.
The final point is that you only have single connections from each of your WAN connections which begs the question as to the purpose of having two WAN switches?
==> Customer is having 1900 series of router , only two ports one used for WAN and other used for LAN.
The objective of having two switches is to provide redundancy/resiliency. If you have only one connection from each WAN then why do you need two switches as there is no redundancy?
==> Customer has agreed to have manual change at the time of failure.

Aironet 1142 as supplicant to 2960 switch (NEAT/CISP/MAB)

Hello!
First, my configuration, (then the problem down below):
I have an Aironet 1142 with mulitple SSIDs [mapped to VLANs] connected to Gi1/0/2 on a 2960 switch in a user-accessible area. This switch is uplinked to another 2960 switch in a wiring closet, and the Microsoft NPS server is connected to the wiring closet 2960.
Aironet -- 2960 [user area] --- 2960 [closet] -- NPS RADIUS
I have the user-area 2960 configured as an authenticator switch for dot1x, and port Gi1/0/2 is authenticating the Aironet via MAB to RADIUS. RADIUS is sending VSA device-traffic-class=switch to the 2960. The closet-2960 has no special 802.1x configuration, nor is it an authenticator swtich; it just has a manually-configured trunk port to the user-area 2960 [for now; i'm trying to take this one step at a time!].
The user-area 2960 correctly converts port Gi1/0/1 to a trunk port when the Aironet is authenticated [via MAB]. The Aironet boots up, the port is opened, I can ping the Aironet on the native VLAN, and all is well [so it seems]. The Aironet's dot11Radio is configured for two SSIDs and mapped to VLANs, which are being spanned via STP thru the user-area 2960 and the closet-2960. STP is correct and verified on all switches.
I have DHCP snooping configured on the user-area 2960 but only for VLAN 1 [but NOT the wireless user VLANs], the trunk port to the closet 2960 is a trusted port. Hosts on the wired ports on the user-area 2960 are able to get DHCP IPs. On the Aironet, "show dot11 associations" shows hosts on the SSIDs are getting DHCP addresses. Again, I am *NOT* running dhcp snooping on wireless SSID VLANs [i read elsewhere that can cause problems as users roam between Aironets].
I do have CISP configured on the user-area 2960. I do not have CISP configured on the closet-2960 [best I can tell, that's not required at this stage, but I could be wrong].
Despite the alleged documentation, I could not get the Aironet to use a dot1x credentials profile to authenticate to NPS/RADIUS as an 802.1x supplicant, which is why I resorted to MAB for this exercise. The Aironet simply would not run dot1x [best I could tell]. The documentation and configuration didn't seem complex, so I was quite confused.
I have upgraded the Aironet to the latest 12.4(25d)JA2 software, and the 2960 is at 12.2(55)SE7 [i saw 12.2(58) has some issues, but i'm willing to be persuaded otherwise, based on sound advice].
Ok, now the problem:
Users on the guest wireless SSID (Vlan 20) say they cannot connect. Yep, classic. VLAN 20 is trunked and spanned to all the sufficient places. The Aironet shows users in the associations list for that SSID with IP addresses from the DHCP server! DHCP snooping is not configured on that VLAN.
I read another support forum post saying CISP and MAB could cause problems with "disappearing" ARP entries. I appear to have that problem. However, the user on the Staff wireless (VLAN 10) has full access. Am I running into a problem with "multi-host" authentication config? Via tcpdump on my firewall, I see nothing but broadcast and multicast traffic coming from a host on VLAN 20. What puzzles me is how I do see *SOME* traffic from a VLAN 20 host on this SSID, but no unicast traffic! Argh!
Since you're going to ask, here is my port config for this AP on the 2960 authenticator switch in the user-area, and the AAA config pieces:
#sh run br | in ip dhcp
ip dhcp snooping vlan 1
no ip dhcp snooping information option

Ok, what am I missing??

The problem lies in the wired Ethernet port on the Aironet. I did not submit that configuration because I thought it was simple and unrelated. Here is what I had:
interface GigabitEthernet0.20
encapsulation dot1Q 20
no ip route-cache
bridge-group 20
no bridge-group 20 source-learning
no bridge-group 20 unicast-flooding
bridge-group 20 spanning-disabled
The correct configuration should have been:
interface GigabitEthernet0.20
encapsulation dot1Q 20
no ip route-cache
bridge-group 20
no bridge-group 20 source-learning
bridge-group 20 spanning-disabled
The line "no bridge-group 20 unicast-flooding" should not be applied to the wired port. That's stupid. With that erroneous command, the wired port will forward only broadcast and multicast traffic! Unicast traffic will be dropped. Oops.
However, I do not understand why applying this to the radio interfaces has no effect there. I have yet to find any conclusive detailed answers, either. Regardless, my original problem is fixed.

IOS on standby switch

Hi.
I am running VSS on 4506-E switch with Supervisor 7L-E. Currently running IOS on both switches is "cat4500e-universalk9.SPA.03.05.03.E.152-1.E3.bin" which is latest one. I have been asked to run "cat4500e-universalk9.SPA.03.04.03.SG.151-2.SG3.bin" so i think i need to degrade IOS.
Since switches are running in cluster so copying image will be pasted into active switch. Pls tell me how could i do copy this into standby also.
Pls tell me if IOS "cat4500e-universalk9.SPA.03.04.03.SG.151-2.SG3.bin" is stable for VSS.
Also let me know if this support SSH login.

Once you copy the image into the active switch, you can copy it onto the standby unit by specifying the target as slavebootflash. e.g.:
copy bootflash:/cat4500e-universalk9.SPA.03.04.03.SG.151-2.SG3.bin slavebootflash:/
Once you have copied the image onto both supervisors, follow the procedure for upgrade / downgrade of a VSS described here.
I don't know personally of any stability issues with the 3.4(3) IOS-XE image - VSS or otherwise.
The "k9" in the image name indicates support for encryption which includes the ability to create an rsa key and configure ssh transport.
