Catalyst 2960 POE Switch Consumption Mode

Hi,
I'm curious how I can configure a 2960 to function in POE consumption mode. I know with other switches you can explicitly configure them to only give devices the power they consume and not power based on what class the belong to.
I have read that the following command should do what I need:
power inline consumption wattage
...although I would have thought I wouldn't need to specify the wattage if I wanted the device to tell the switch how much power it needs.
Thanks

Hi,
The "power inline consumption" command is a global config that applies to the entire switch to override the default:
from the command reference guide
Use the power inline consumption global or interface configuration command on the switch stack or on a standalone switch to override the amount of power specified by the IEEE classification for the device by specifying the wattage used by each powered device. Use the no form of this command to return to the default power setting.

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

2960S PoE switch into a non-PoE stack

I have two 2960 Stacks
Stack # 1 is a PoE stack with two WS-C2960S-48FPD-L with TenGig uplinks running c2960s-universalk9-mz.152-1.E.bin.
Stack #2 is Non PoE stack with three WS-C2960S-48TS-L running c2960s-universalk9-mz.150-2.SE2.bin.
I need to add an WS-C2960S-24PS-L for additional PoE port capacity. If I add it to Stack #1 I will have three switches in both stacks, and all PoE switches will be part of the same stack. I am just wondering If I can have disparate switch models in the same stack running the same IOS? If I add the new WS-C2960S-24PS-L to Stack #2 I will end up making this stack a 4 switch stack with three non-PoE switches and one PoE switch. If I add the PoE switch to this stack will I have access to the PoE capabilities of that one switch. Again with the question can I have disparate switch models in the same stack running the same IOS?

I am just wondering If I can have disparate switch models in the same stack running the same IOS
Yes. You can have a different models of 2960S in a single stack. The main important thing is all members of the stack should have the same IOS version.

FlexStacking Catalyst 2960-X Switches

Just ordered two 2960X switches with FlexStack Modules (and appropriate cables).
Looking at the documentation I could find, was unable to determine one thing.
Do I do the Express Setup before or after I mount and wire the stack. I know they'll end up being "virtually" one device and will be managed that way. Documentation unclear about this.

Okay...
I suspected that was going to be the answer. Just wanted to hear someone say it.
Will advise once equipment is delivered and configured.
Thanks...

SFP Mini-GBIC for Catalyst 2960

We are looking at getting the SFP Mini-GBIC from HP HP-J4858C. This transceiver module is Gigabit-SX-LC Mini-GBIC. Will this module work on our Catalyst 2960 PoE switches and will it also work using a MultiMode fiber?

I've used non-Cisco GBICs successfully in Cisco gear. In the event of a problem related to the link, the TAC MAY refer you back to the HP or suggest using a Cisco transceiver.
Running a multimode connection that close to the length limit is not the best idea but if that's all you have installed (and you can't get a single mode link installed) then it is what it is. A single mode GBIC WILL NOT operate over multimode fiber.
The high level specs cite distance but the real indicator of usability is better characterized by loss. As long as you getting adequate light levels at the receiver, you will be OK. Problem is, it's not easy to tell light levels (on a non-SMD type transceiver such as Leo suggested) without some relatively costly measurement equipment.

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.

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...?

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.

Cisco 2960S FPS-L PoE switch with Avaya 9811g VOIP setup

Hello,
I am connecting a setup for data/voice connecting Catalyst 2960S-FPS-L PoE switch with Avaya 9811g series VOIP phone. As per my knowledge cisco switch works well with Cisco phone as it has got some builtin "Macros" and Intelligent PoE recognition when we connect device getting the details of another device through CDP. I understand I have to create data and voice vlan with QOS then enable trunking on the interface to other switch that is also 2960. Little confuse if is there any compatibility issues with Switch and Avaya phone regarding protocol/data/voice...?
Do I have to do PoE config for each port on the each interface?
any help or detail config will help.
Thanks in advance.

Hi I am back after good research. created two vlan data and voice with trunk on interface1/0/48 given below config..
connection b/w 2960s FPS Switch and Avaya 9611g IP Phone.
lldp/cdp is enable on switch
So I created this config if some one can take a look .
expert advise if something wrong?..
I am only concern with Voice and PoE as voice is my priority. do i have to map something for voice quality?
also if i create another Trunk port one allow voice other allow data both cable will go to switch will that be issue?

NAC modes supported by the Catalyst 2960

Hello, we want to be able to use NAC with agentless hosts. From my reading the NAC-L2-IP and NAC-L3-IP modes are the only modes that support NAH's.
Are these two modes supported by The Catalyst 2960 switch?

This should answer your question:

Catalyst 2960S-LPS-L PoE only on specific ports not working

Hi,
we have Catalyst 2960S-LPS-L (48 Ports) here which in general works fine.
If i connect a Cisco Access Point (2602), it´s powered up via PoE, but on some ports this is not working; it just doesn´t power up. The port configuration is exactly the same. I rebooted the switch, but still the same.
Any ideas how to troubleshoot this? Is it possible, that the PoE capability on some ports is just broken?
Thanks
Heinz

Hi,
it did all this, but there are no irregularities. IOS is version 152-1.E2

Catalyst 3560 24 port-PoE switch powers on but no STAT LED and console not responding

I rebooted my Catalyst 3560 24 port PoE switch and when it turned on only the STAT LED went green the other LEDs are off. I get no response from the console port using putty and the cable I used before this happened. I tested the cable on another switch and it works fine with putty. What can I do with this switch?

This unit was purchased before I came to our company. There is no support or maint contract. I'm sure the unit is several years old...we'll call the vendor and see what they'll do..not expecting much.
