IP SLA responder on Catalyst 2960S stacked

Hi
I have a pair of switches stacked:
Switch Ports Model                          SW Version          SW Image
     1    52      WS-C2960S-48FPS-L 15.0(1)SE             C2960S-UNIVERSALK9-M
*    2    52      WS-C2960S-48FPS-L 15.0(1)SE             C2960S-UNIVERSALK9-M
When I try to enable ip sla responder on the stack I get:
%SYS-3-HARIKARI: Process IP SLAs Responder top-level routine exited
I have been able to find a bug in the toolkit. Should ip sla responder be supported on the
stack as above?
Thanks
Lee Flight

I can confirm 15.0(1)SE3 still has the bug.
I just tested 15.0(2)SE3 released yesterday in a lab environment and....... (drum roll)..... no more HARIKARI . Hardware were two WS-C2960S-48FPS-L unstacked (one of them with installed stacking module though)
Haven't tried the earlier 15.0(2) (i.e. SE, SE1 and SE2) releases - maybe they work too.

Catalyst 2960s Stacking with different IOS versions

Hello Forum Team;
When adding a new switch with older ios version to an existing stack (flexstack) does the new switch will be able to join the stack?
Thanks in advanced!

Hi,
In a stack/flexstack all the switches should have exact same IOS version, otherwise there will be a version mismatch on the stack and the new switch will not be able to join the stack.

Catalyst 2960S switch stack support?

I have a customer with a new stack of four Catalyst 2960S switches.
Is this configuration supported by Onplus?
I can't seem to figure out the login access and enable access credentials
so that Onplus can backup the configuration of the stack.
Jeff Bright
Bright Systems
Broken Arrow, OK

I also have a 2960S stack in my office. I checked my handy OnPlus iPhone App and it shows backup, restore, and firmware all equal 1 which I recall correctly means backup is supported. I'll double check when I get into the office to ensure backups are actually working.

Web Authentication Catalyst 2960

Hi,
I am trying to configure fallback Web Authentication on a catalyst 2960 switch. The goal is to authenticate clients via web authentication who are not 802.1x compliant (the 802.1x part is working fine) and allow them restricted access to the network. The problem is that the web authentication seems to fail.
The equipment regarding my question : catalyst 2960 switch (version : 122-37.SE) and a FreeRadius.
Here's what happens :
The authentication window pops up in my browser and the Access-Request is sent to the RADIUS.
The RADIUS in term responds with a Access-Accept. The debugs running on the switch show that all this information arrives correctly at the switch and the Authentication debug outputs a 'status = PASS' and the Authorization debug outputs a 'status = PASS_ADD'. In spite of this the browser on the client outputs a 'Authentication failed' message.
I've read the manual and the Cisco-attribute Value pairs were mentioned : 'priv-lvl=15' and 'proxyacl ...'. Are these mandatory for it to work? Since I'm not configuring any switch login authentication via RADIUS.
Any suggestions ?
Thanx in advance

Yes, they are mandatory.
If priv-lvl=15 is not returned to the switch, the user will see ?Authentication Failed? and the access-list will not be applied. If the source field in the proxyacl statements is not ?any? or there are other syntax errors, the user will see ?Authentication Successful? but the access-list will not be applied and the user will be denied access to the network.
Not sure about the specific FreeRADIUS config, but you need to setup the ?[026\009\001] cisco-av-pair VSA. It would look something like:
priv-lvl=15
proxyacl#10=permit ip any any
Let me know if this gets you squared away,

Catalyst 2960 vs 3750

Long time reader here but first time poster. I am looking into upgrading our network switches soon and I'm trying to decide on a design now. Let me give some background information on the network.
Currently we have a Catalyst 5513 with a Supervisor II, ten 24 port 10/100 cards and a 12 port fiber card installed. There are also two 48 port Alcatel switches that are uplinked to the 5500 as well as six Catalyst 2900XLs (on the factory floor) uplinked to it via fiber. There are about 40 servers and 350clients in total in the building. All servers and most of the clients in the office are connected directly to the 5513. We will be consolidating buildings soon and plan on adding another 200 devices to the network (office and factory floor area).
I was thinking we should get two Catalyst 3750G-48TS and a 3750G-12S in a stack for the core switch. Then use Catalyst 2960-48TC-L switches uplinked to the 3570 stack for the access layer. Does this make more sense than directly connecting all the clients and servers directly to the 3570 stack? What would be the advantages/disadvantages of each setup besides cost?
Thanks for any help you can provide!

I tend to go with a more modular approach and hang nothing off my core except otehr switches. Put your servers on their own switches as well. There are a few reason i do it this way.
The first is I run two cores for redunacy. by giving servers their own access layer switch, i can isolate them from a core failure.
Second, ports on a core switch tend to be more expensive. I know I'm going to be adding servers in the next few years. Its cheaper for me to buy more 3560's then more blades for a 6500.
Third, modularity. I can make more changes to either the core, or edge switches and not effect the other. Say you find out down the road, that the 3750 stack isnt quite moving the number of packets you need. If you plug end users and servers into your core now, just picture how much of a bear it will be to replace the core. Always try to go the route that will give you maximum flexibility and growth.

Catalyst 2960-x Tel 1 and g49, bug

Hi Cisco Community
I am experiencing a very strang bug or it's just a "feature". We are setting up 3 Catalyst 2960-x (EX5) as a stack. Te 1/0/1 and Te 2/0/1 are bundled as Etherchannel. (works fine "In-channel-group")
But we just can not connect anything else to Te 1/0/2 or Te 2/0/2.
When i checked the "sh run" i noticed that there are the Ports g49 and g50. What should be Te 1 and Te 2.

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)

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.

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 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

2960x & 2960s stacking?

Hey guys recently I tried to introduce a 2960x switch into a 2960s stack.
I prepped the bpth switches and made sure the prefer sdm was set to default as well as setting the stack port speed on the 2960s stack to 10 so its would be compatible.
Once i stacked the switches i got a version mismatch error and an auto upgrade message, after waiting roughly 40 minutes with no succcessful upgrade i removed the X switch from the stack
below are the IOS running on both switches
*    1 52    WS-C2960S-48FPS-L 15.0(2)SE5            C2960S-UNIVERSALK9-M
     2 28    WS-C2960S-24TD-L   15.0(2)SE5            C2960S-UNIVERSALK9-M
3 52    WS-C2960X-48FPD-L 15.0(2)EX4            C2960X-UNIVERSALK9-M
Any thoughts on how to successfully stacked these?? Thanks in advance

Hi,
some info about stacking different switch 2960S with 2960X.
More info is available at:

Hope this can help you.
Mixed Stacks: FlexStack and FlexStack-Plus
The 2960-S and 2960-X support a mixed stack of 2960 models. All these 2960 models run the FlexStack protocol, allowing them to be stacked together into a single stack. The exception is the 2960-XR does not stack with either the 2960-X or the 2960-S. The 2960-XR has the IP-Lite feature set, and this is not compatible with the LAN Base feature set on the 2960-X and 2960-XR. Table 2 shows all the allowed mixed stack combinations. What is crucial is the Cisco IOS Software feature set. All 2960 models with the LAN Base Cisco IOS Software feature set can stack together.

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?
