Cisco 2960 Series Switch Architecture

Hi all,
I wanted to know if there is a document or an article which describes 2960 series architecture specifically for model WS-C2960-24-S as there is for 2600 series in the following link:
http://www.cisco.com/c/en/us/support/docs/routers/2600-series-multiservice-platforms/23852-2600-architecture-23852.html
Thanks.

Hi,
You should be able to find the information that you need here:

Thanks,

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.

Cisco 2960 series mismatch

i have a switch, that shows next
Switch Ports Model SW Version SW Image
* 1 26 WS-C2960S-24TS-S 12.2(55)SE5 C2960S-UNIVERSALK9-M
but!
WS-C2960S-24TS-S <- what does this meen?
what i ask about:
catalist 2960 have 2960-S-series and simple 2960 (not S), and i hav'nt found WS-C2960 with S-suffix at http://www.cisco.com/c/en/us/products/switches/catalyst-2960-series-switches/models-comparison.html
there is WS-* only without *S.
what the device vertion is real and where can i find info about this device?

I found the following info:
"WS-C2960S-24TS-L is Lan Lite Switch.but WS-C2960S-24TS-S is the Lan Base. The obvious differences is hardware differences.The LAN Base owns advanced Layer 2 and mainly is designed for large enterprise. However, The LAN Lite offers entry-level L2 features ,which aims at mid market deployments."

Nexus 2K to Cisco 2960 IOS Switch

Hi,
I am trying to connect Nexus 2K FEX to Cisco 2960 IOS Switch (Trunk config) and causing spanning tree loop having issues. I am aware that I should't be connecting non host port to 2K FEX but it's corner case. I have done similar setup with Access Port configuration and didn't faced any issues.

Should I configure port as "spanning-tree port type network" and create VPC and "storm-control broadcast level" to stop future occurrence? OR Do i have to configure anything else to prevent spanning-tree loops?
Thanks for your help
Ritesh

Hi,
spanning-tree port type network is used for VPC peer-link. Try creating a new VPC and add ports 107/1/47 and 108/1/47 to it and a Portchannel on the 2960 and test.

Cisco MDS series switch details

Hello I 'm new to CISCO Switch world.
I 'm working as Clariion Admin and have have taken up the responsibilty to manage switches.Since,i am a novice i need little guidance on how work on cisco switches.I know the Zoning (how zoning done on MDS 9000 series switches) part ,but would like to venture deep into the details on CISCO MDS series switches.
Like, the use of Port channels etc.
Will really appreciate if some one can help me with a link or place ( not the configuration guide) where in i can find details on concentrated more on the theory part .
Thanks in advance!

Actually the best info is in the configuration guides. There are some external companies that run training sessions on the MDS to provide in depth training. There is the MDS cookbook available on CCO that is also a good point of information. If you search on 'MDS white papers' after you login into Cisco.com, there are several good documents that might meet your needs.
Hope this hels,
Mike

Cisco 500 series switches

Dear support,
Can Cisco 500 series switches deliver 24V on the access port for POE operation?
Best Regards

I belive the 802..2F and 802.2at poe standard is strictly 48v. I haven't found anything to the contrary. There are inline convertes 48v-24v or something like this that can be used with a non poe switch: http://www.digital-loggers.com/poe24.html but that means all conected device would be off the same access port / vlan.

SNMPv3 on Cisco 2960-S Switch to NCS

Can anyone point me to some good instructions on how to set up SNMPv3 on a Cisco Catalyst 2960-S switch in order to manage it with Cisco Prime NCS?

here is link which explains snmp config for 2960s

Cisco 300 series switches with 802.3at standard

I'm a bit confused as to which of the 300 series switches supports the 802.3at standard. According to the website, the SG300-28P supports it. But in the quick start guide for the 300 series, only the MP models (excluding the SF302-08MP and SG300-10MP) including the SG300-52P has it. Can someone give me a difinitive answer to this? Thanks!

LJ,
P = PoE capable. On the 300 series, half of the ports can provide 15.4W, or all can provide half that.
PoE+ is NOT SUPPORTED.
MP = Maximum Power. This means that all ports can provide up to 15.4W. PoE+ is supported on some models only.
PP = PoE Plus. Can provide up to 30W on a single port. Note the maximum PoE budget for each switch. Also,
half of the ports can provide 15.4W, or all can provide half that - any extra power used by PoE+
MPP = Maximum Power and PoE Plus. This means that all ports can provide up to 15.4W - any extra power used by PoE+
According to the Data Sheet:
"Switches support 802.3at PoE+, 802.3af, and Cisco pre-standard (legacy) PoE. Maximum power of 30.0W to any 10/100 or Gigabit Ethernet port for PoE+ supported devices and 15.4W for PoE supported devices, until the PoE budget for the switch is reached"
The PoE+ models are brand new and are not widey available yet. I did a web search for SG300-28PP and found that at least a few online resellers have it in stock.

Unable to hard code the ports of cisco 3750x series switch

hello,
I have tried with hardcode to 1000 7 Full on the ports which are connected to another switch.
After changing the port to auto from one side of the switch port came up. Is there any solution to make port up when both sides are hard coded to 1000 & full duplex.
Simple Words:
Switch 1 --> Switch 2 --> Hard coded to 1000 & Full --> Down.
Switch 1 --> Switch 2 --> Auto on one end to Switch 1 --> Up.
Switch model:
Switch 1 Cisco 3750x (Gi Switch)
Switch 2 Cisco 3750 (Gi Switch)
Regards,
Ezra.

Yes, it's possible without a straight through cable, enable auto/auto both sides. Otherwise you'll need a cross-over cable.
BTW, if your standard is hard coding copper gig ports, for speed and duplex, you might consider bringing your standard up to date. Copper gig standard went much further in how auto/auto is supposed to work. By disabling auto/auto, I believe, you're also disabling some error monitoring too. Generally, all the major players, e.g. Cisco, would recommend auto/auto for copper gig Ethernet.

Cisco 300 series switches

hi all
Ive looked through some of the online content but dont see a definitive answer to my question about the physical size of the switches, are they all 19" rack mountable or desktop?
I look forward to a confirmation..

Cisco 4500 series switch-Supervisor Engine.

Is it possible to add two different supervisor engine module in a chassis(WS-C4507R+E Chassis)? (WS-X45-SUP7E in slot 3 and WS-X45-SUP6E-
Redundancy in slot number 4)

http://www.cisco.com/en/US/docs/switches/lan/catalyst4500/12.2/31sga/configuration/guide/RPR.html
Redundancy requires both supervisor engines in the chassis to be of the same supervisor engine model (same model, same memory, NFL daughter card and so on), and to use the same Cisco IOS software image.
Thanks
