Cisco 2951 poe limitation for switch module ?

Hi , i have cisco 2951 router with switch module :
SM-D-ES3G-48-P
there are many poe devices connetced to the switch module .
the problem we face is , sometime the poe devices get down and up (flapping)
after investigatipon by command
show power inline police
i found the devices is getting about 60 Watt , and there is remaining power about 200 watt.
the question is , how to investigate and troubleshoot this issue ?
is there any limitation in the power for that platform ?

Hi ,
thanks for reply
the issue is :
interfaces get down , then up
some times it still down and take long time to be up agian !!
exactly if i did shutdown , then no shutdown
thats the problem that we face !
sorry cant access the swith now , if i can i will post the config i have.
thanks for ur time

Best way to connect 2 Cisco 3750 PoE 24-port Switches

Hello. I have 2 Cisco 3750 PoE 24-port switches in a small office environment. Right now I have a trunk configured off my ASA 5505 to switch 1, and then just an access port configured on a port (switch 1) and an access port configured on a port (switch 2) to connect them together. These switches also have 2 GB SFP ports but they are not being used in this configuration.
I was curious to know if anyone had any better recommend configurations for connecting these 2 switches together? I'm not sure if this particular model can be stacked?

What are the exact model numbers (should be written on a sticker)?
You will know if they can be stacked as you will see the 2x stack ports on the back of each switch :)
If they can then that is probably the way to go unless you want to keep them as separate switches for some reason.
If you want them separate, I would connect them via a Trunk link at least so you can have the same Vlans on both.
Thanks

Did Cisco ISE have limitation for policy setting?

Deat All,
Did anyone know about Cisco ISE limitation about policy setting?
Right now my setting for windows posture policy around 200 windows patch checking, did ISE have limitation such as maximum windows patching policy line?
Thanks you
Best Regards

Here is the nswer for your first question.
Cisco ISE profiler collects a significant amount of endpoint data from the network in a short period of time. It causes Java Virtual Machine (JVM) memory utilization to go up due to accumulated backlog when some of the slower Cisco ISE components process the data generated by the profiler, which results in performance degradation and stability issues.
To ensure that the profiler does not increase the JVM memory utilization and prevent JVM to go out of memory and restart, limits are applied to the following internal components of the profiler:
Endpoint Cache—Internal cache is limited in size that has to be purged periodically (based on least recently used strategy) when the size exceeds the limit.
Forwarder—The main ingress queue of endpoint information collected by the profiler.
Event Handler—An internal queue that disconnects a fast component, which feeds data to a slower processing component (typically related to a database query).

Configuring - Cisco 2921 with Switch Module/POE PS and 3750-x 24 port switch

This is what I have
- Cisco 2921 router
         with SM-ES2-24-P switch module and
                 POE power supply
-Cisco 3750x- 24 port Switch
I have port G1/0 (which connects to 24p Switch Module port g0/26 logically) configured with 3 sub interfaces (management, User and VOIP)
I want to connect 3750x to G0/1 on 2921 via fiber GBIC but want to use same three VLANs
I can not daisy chain 3750x via the switch module because it does not have fiber port.
I do not want to create another routed (g0/1) interface because I want to keep Users on both switches on the same subnet without further splitting the subnet in two.
I hope I am not making this confusing.
How can I bridge g1/0 and g0/1 so I can pass vlan traffic between two switches?
Second problem i have is ...
I have a VOIP connected to switch module (SM) and it is not getting any power.
I went in to all the interfaces on SM and issued power inline auto command
On the SM (sh power inline) - available is 0.0(w)
on the 2921 (sh power inline)
   - power supply status is good,
   - maximun power available is 280.
   - interface G1/0( which connects to SM)
      *device is unknown
      * powered off
     * allocated 0.0 watts.
I already tried resetting SM
Is there any other command I need to issue?
thanks for your help.

I'm having a similar issue. I can get trunked connectivity between the switch module and the router if I put the IP address on the router sub interface, but not if I put it on a VLAN interface. I was hoping to have it on a VLAN sub interface on the router so I could use Gig0/1 and Gig0/2 to connect other switches and have them on the same VLANs. I'm using Gig1/0 on the router side and Gig0/51 on the switch side (48-port module).
Any help? Am I on the wrong track altogether?

Can you Connect Cisco switch modules for to N2K?

I have not seen anything about connecting Cisco Switch modules for Blade Chassis to fex. Does anybody now if you can do that?
thank you.

thank you Lucien.
I think you got a right name for N2Ks, a NIC card extender. In my opion N2K should be able to support Blade switches. Not every company has just rack mount servers, most enviroment is mixed. In my case, I run out ports on N5K, but plenty available on N2K. I want add two more blade centers with gig switch modules in them. now I have to buy a N5K!!!. I'm sure Cisco can make N2K to support switches too.

IP changes on a Cisco Switch Module for IBM BladeCenter

Hi everyone,
I was just wondering if anyone out there is using the MDS modules for IBM BladCenters and if so whether you had had any problems changing the IP details through the BladeCenter management interface. I needed to change a subnet mask but since making the change I've lost all IP connectivity to the module and it shows Status: Disabled under the new IP Details.
I've tried resetting the module to factory defaults and whilst this seems to have had some effect (e.g. the fc ports have all gone down) it has given me any IP connectivity or allowed me to set up a new IP address.
Has anyone else seen this and if so, how did you get round it.
Thanks,
David

Hi Mike,
I saw that it doesn't allow you to change any of the IP config through the CLI, hence why I moved on to trying the MM.
Fabric manager can't connect to the module on it's address (I was just correcting the subnet mask) and it is not pingable from anywhere on the network, so it seems to me that the IP path out through the MM isn't working.
I tried the same process on one of our test chassis and the same thing has happened there.
Configuration for that slot looks like this on the MM:
Bay 3 (Fibre SM)*
Current IP Configuration
Configuration method: Static
IP address: 172.20.221.9
Subnet mask: 255.255.255.0
Gateway address: 172.20.221.3
New Static IP Configuration
Status: Disabled
To change the IP configuration for this switch module, fill in the following
fields and click "Save". This will save and enable the new IP configuration.
IP address 172.20.221.9
Subnet mask 255.255.255.224
Gateway address 172.20.221.3
How does the MM communicate with the module (telnet/snmpv1/snmpv3/ssh?) and with what credentials. I'm thinking that there must be something in how we've configured the switches that is breaking this in some way (we've enabled aaa auth for login, removed some default SNMP details, and disabled the telnet server).
There seems to be rather a lack of docs on these modules, is there anywhere to find out more detail on how they all hang together.
Thanks for your interest and help,
David

Cisco Visio Stencils for newer modules

I have been trying to find stencils for 6500 modules released in the last couple of years, and have had very limited success. I need stencils for WS-X6748 modules, WS-X6724 modules, WS-X6848 modules, WS-X6816-2T modules and SUP-2T modules, as well as the NAM3.
If anyone can tell me where these can be found, it will be greatly appreciated.

Hi,
Most of what you listed are on the latest Switches-Catalyst 6500 located on the Visio download page:
http://www.cisco.com/en/US/products/hw/prod_cat_visios.html
The WS-X6748 and WS-X6724 modules are not in that file. I will ask the product group if they will approve production of those items.

Cisco 2951 router AC-PoE power consumption, meaning of the mention "Platform Only" in the datasheet.

Hello,
I have a question regarding the power consumption of a Cisco 2951 router with an AC-PoE power supply (without PoE boost).
In fact in the table (n°7) of the Cisco 2900 Series ISR (G2) datasheet, that sum up the power consumption data for Cisco 2900 series routers there is the line : "Maximum Power with PoE Power Supply (Platform Only) (Watts)", and I would like to know what is exactly the meaning about the mention "Platform Only".
Thank you for your help, best regards,

Hi @francois.trarieux,
This is the maximum power that is consumed exclusively by the router from the PoE PS (Power Supply). The power capacity that the PoE PS gives to other PoE devices (IP Phones, Cameras, APs, etc) is specified in the line below "Maximum End-Point PoE Power Available from PoE Power Supply (Watts)" of the datasheet.

POE from 3524PWR Switch for 1130AG AP?

We have a bunch of 1130AG LWAPP access points that we are installing in various locations. Those locations with newer 802.3af switches such as the 3750's and 3560's power the AP's without issue. However we have mixed results plugging them in to older Cisco POE only 3524PWR Switches.
For the most part if we plug the 1130AG's into the 3524PWR's with short patch cords they power the radios up. However, if we connect them to a longer network line (80 to 100 feet) they disable the radios and WCS alarms tell me that the switch could not supply enough power for the radios.
The Quick Start Guide (page 14) shows the 1130AG supporting both Cisco POE and 802.3af power. Is there any way to get these to reliable power up on 3524PWR switches or do I need to use power cords or power injectors?

Hi Jim,
We had this happen to us due to the same PoE problem. The 1130 requires either IEEE 802.3af power **or needs a setting on the WLC for using power injector or Cisco Pre-Standard PoE. Our older switches could only provide Cisco Pre-Standard PoE so we had to tweak the WLC Power setting for these AP's. Once we did that the Radios came right up. Here is a reference;
You may have to enter the following info in the WLC;
While the AP boots, with its Intelligent Power Management feature, it negotiates with the switch via Cisco Discovery Protocol messages in order to provide the necessary power to the AP. Even though the power injector is connected to the AP, the AP that uses this Intelligent Power Management feature gives priority to the Cisco Discovery Protocol information in order to identify whether or not the switch can provide the power. Therefore, after the Cisco Discovery Protocol message shows that the switch does not provide sufficient power (since it is not an inline power capable switch), the AP disables its radios. At this time, the status LED of the AP turns orange and this error message is recorded:
[ERROR] : AP has not enough in-line power
to enable radio slot 1 In order to overcome this problem, issue the
config ap power injector enable installed
command on the controller that is connected with this AP. This command is available from controller version 3.2.116.21. Ensure that you use the correct version in the controller.
This command specifies that a power injector is used in order to supply sufficient power to the AP.

390W PoE-Budget for Cisco 3650-24 Port Model

Can anyone provide a "show power inline" with the available PoE-Budget for the new Cisco 3650-24 PoE+ Switch? We have to be sure that the 390W from the Datasheet is 100% correct.
Many thanks
Manuel

I am not sure how many people have deployed 3650 series switches, as they are brand new. If you are not sure about the documentation, ask your system engineer to clarify it for you.

Cisco 2951 for BGP at AS edge

hallo,
our customer has a server farm in a data center.
At the moment the farm has connectivity with only one ISP but sometimes it has service discontinuity.
Customer wants to become AS and having two ISP connectivity for backup purposes.
He needs to evaluete two cisco routers to use at AS edge with BGP.
At the moment he says that the throughputh with the server farm is max 15Mbps and in the future he thinks that it will not increase.
We think about cisco2951 routers with 2GB ram.
Is cisco 2951 adeguate for this task ?
best regards

Cisco 2960S-24TS-S using SFP modules between switches

I am using Cisco 2960S-24TS-S using SFP modules for two different speed requirements, I have two SFP ports using 100Mbit modules and the other two SFP ports using 1000Mbit modules.
I have two Cisco 2960S-24TS-S switches connected together via a fiber optic cable, and each SFP module is on port 28, with a 1000 Mbit SFP module in each, and the two switches will not connect. The fiber was checked with a light tester not a db kit.
Do I need to have SFP port specific setup details in a configuration file for the Cisco Switch or does the SFP module handle this?
" interface GigabitEthernet1/0/28" - set up in config file for the port. Does this need to dictate "interface 100" or "1000MbitEthernet1/0/28" instead?

The ports should auto-negotiate speed you should not need to hard code them to get them to come up , Are the ports showing up/down or down/down can you post the show interface for each side and the show run int x/x for each port
