Problems acccessing SG300-28P via management interface

I have a new SG300-28P, and have had occasional issues with being unable to connect to it via anything other than the serial port. I have connectivity between my machine and the switch (tested with ping each way), and in fact, have the same problem if I take a laptop to the switch and connect them directly.
What happens is that though the switch is operating normally, http, https, ssh and telnet attempts to access all fail in one way or another. Ssh and telnet either yields no response or a refused connection (even though those services are enabled). For http and https, I'll occasionally get enough of the web page to be able to tell what it is ... but attempts to log in just don't work.
While this is happening, the CPU and packet load on the switch is very, very low.
Rebooting didn't help entirely, though it may have made it better. Resetting to factory defaults and then reconfiguring makes it work.
This is using the latest firmware: 1.2.7.76.
Searching the web for this sort of failure doesn't yield any results -- maybe I'm the only one to see this?
I don't know what else I can do to diagnose ..... I've got it working without trouble now...

I have this problem too. It seems to have started from either when I upgraded to the latest firmware and/or changed the management interface from the default (vlan 1) to vlan 11. It will stay up and pinging for anywhere from a few minutes to 3 hours, then I lose all connectivity until I reboot the device.

Web service invocation problem on host hostname and port 8000 protocol : http logical port name : LP_WS_SMDAGENT_MONITORING

hello colleagues,
In the phase Connect Diagnostics dont show the Agent available in SLD, but when go to SLD i have the agents,
Error,
Connect Diagnostics Agent
The table does not contain any data
Agent availables in all SLD
SOAP:1.007 SRT: Unupported xstream found: ("HTTP Code 401 : Unauthorized")
Web service invocation problem on host hostname and port 8000 protocol : http logical port name : LP_WS_SMDAGENT_MONITORING
Thanks

OK, then pls follow below steps;
- Go to step 'Create Users' in solman_setup System Preparation scenario and make sure the user SM_INTERN_WS has a green status. Use the 'Test Login' button to make sure the user is not locked and has correct credentials maintained in solman_setup
- Immediately after checking the user status, navigate to Configure Connectivity->Enable Web Services and execute again the 'Create Logical Ports' automatic activity, in order to propagate the correct credentials to the Logical Port definitions.
- If the above operation is not successful, repeat the two steps above, providing a different user Id in 'Create Users' step, eg SM_INTERN_W1. This will prevent situations where the user gets locked by Logical Ports using an obsolete password.
Let me know the results.

Vivek

Issues with processing messages on one receive port causes problems on all the receive ports that are on the same handler

Greetings,
An integrator installed biztalk in our environment to process the hl7 message flow between their source application(s) and several receiving applications. We've had problems with this set-up for a while now because some receiving applications sometimes have
problems processing the messages. Be it either because there's problems with the server that processes the messages of a certain port or because there's problems with the software/daemon/service that needs to process these messages.
The main problem with this, is that the receiving end of this isn't under our control nor under control of the integrator, but when one receive port isn't processing their messages for a while it causes a problem with all the receive ports that are on the
same handler. So other receive ports start noticing a slow-down of their incoming messages until after a while nothing gets through anymore.
What is the best practice to prevent these kind of problems? Should we just create a handler for every receive port? Because that seems a bit overkill.
Thanks in advance.

What do you mean exactly with this question?
"Can you provide some more detail like BizTalk the receiver? "
The adapters are mainly file and MLLP, the MLLP adapters are already seperated from the file adapters (a handler for MLLP and a handler for file).
The problem with all the receive ports is that when one receive port isn't processing its messages (usually caused by the software processing the messages) the other receive ports on the same handler receive their messages/files a lot slower. If for any
reason the problem isn't fixed soon, the other receive ports on the same handler actually stop receiving any messages at all.
Isolating the receive port that causes the problems like la Cour suggested can work, but next time it might be another port that experiences this issue. So we are looking for a way to make sure the whole message flow isn't hindered by one port (whichever
port) that can't process its messages. Or rather by one receiving software that can't process its messages.

SG300-28 28-Port Gigabit Managed Switch

I've forgotten username & password of SG300-28 28-Port Gigabit Managed Switch. Is there any to recover them? but I don't want to lose configurations.

Hi Anton,
You can access boot menu and choose password recovery but this option is only accessible via serial console and after you see Cisco logo hit ESC button once.
Once you choose password recovery current password will be ignored during this current session only so the first thing you need to do is to change and save new password. You can use CLI for this:
switch(config)#username cisco password cisco
switch(config)#exit
switch#wr
and you should be ready to go :-)

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

Problem related USB Virtual COM PORT using PDA module 8.2 on Windows CE

Hi,
I am working on tranferring my application developed on LV 8.2 to a Single-board computer(SBC) running Windows CE 5.0. I am using LV PDA module 8.2 to achieve this. My problem lies in finding the port number of the Virtual COM Port on the SBC. I need to connect a USB RF modem from Maxstream to this SBC and to talk to it using VISA. I have installed the required drivers from Maxstream for converting the USB port to a virtual COM PORT. What is a way to figure out the COM PORT number on a Windows CE device? For a PC, I can see the COM PORT in the device manager but I do not know how to find this in Windows CE. . Also, I have tried using "VISA Find resource" function ..it works on a PC but I do not get anything in the Win CE device.
Any help would be much appreciated.
-Shruti

Shruti,
Is there a way to verify that the Maxstream driver successfully provides you with this virtual COM port? Essentially, what I mean is that if you did not have LabVIEW on this device, how does Maxstream prove that their driver is functional? Does it come with additional software that would be used to configure the USB RF modem? In any case, we would want to try opening any terminal program (like the hyperterminal) to determine what ports are listed for communication. I hope this is useful for you. Please post back when you are able to give this a try. Thanks,
Mike D.

Sb Sg300-10mp 10 Port Gigabit Poe Switch

Good afternoon,
Really need some assistance with this switch please.
When it's switched on it keeps going into a boot cycle. It's never worked but due to reporting it outside the accepted DOA timescale we are unable to return the unit,
Please could someone advise what I need to do?
Thank you in advance,
Amanda

Hi Amanda,
Sure does sound like a real problem.
But the switch has a tremendous warranty and support is free for products under service contract or warranty.
If you would be so kind as to contact the good folks at the Small Business Support Center (SBSC), they will either help fix the product or allow for RMA of the unit. their contact details are on the second URL below.
A SBSC technician will ask for a Cisco Connection online (CCO) ID, if you don't have one, go to the following URL to create one. https://tools.cisco.com/RPF/register/register.do This allows the the technicians to have contact details for you and for you to manage your service requests online at Cisco if that is what you want to do..

Problem with JNI and Parallel Port dll

Hi. I'm doing some testes with JNI. Firs i followed the netbeans tutorial for doing a C programa that prints somthing for java.. like.. "Hello java from C".
So i tried to load a dll from my dll. Like, I have this dll to use the parallel port on windows Xp. So i created a dll to access it an comunicates eoth java.
I did everything just fine.
When I start my Java app, the first thing it does is to load this parallel port dll and configure the functions of it.
After that .. I get this error
EXCEPTION_FLT_STACK_CHECK (0xc0000092) at pc=0x0093d269, pid=2284, tid=3000
Can someone explain why ?
(Sorry if i wasn't clear enough, english is not my native language, so ask if you don't understand something.. )

hi ,
I met the same problem this morning, and searched the www.google.com in order to solve it, as a result, your article was shown on my screen. :)
Till now I have read some technical information and solved my problems. Maybe the solution be useful to you:
==============================
error message : (Environment : Tomcat 5, Windows 2003, Mysql5)
2006-3-29 11:53:48 org.apache.catalina.core.StandardWrapper unload
message: Waiting for 2 instance(s) to be deallocated
==============================
cause: the number of connection to database exceeded.another word,too many connections.
==============================
solution: close the connection when it becomes useless for your program. :)

ps. Sorry for my weak English . hehe ....

I have problem with delay in serial port

I have problem with serial port. I have connected two computers by serial port and I need to create program in Labview for transfer strings using start bits and stop bits. My problem is that my program is working quite well ...when I press start bit it starts to concatenate strings and if i press stop bits it stops...this is the purpose of this program...but problem is that it working only with delay...and need that this program dont need delay, because it can only concatenating data depends on delay from start bit....I wana solved problem with delay...I dont want using delay process in my program, but allways when I try to delete this delay it stop works correct
here is my program

Ok this should be simple - if I understand you correctly.
You have the VISA session initialized with read termination character enabled. So reading the number of bytes at port is NOT the correct way to read from the port. Set the read number of bytes to something large (say 4096) and the read will return as soon as a termination character is received (or timeout).
You'll need to make sure the sending device is configured to send termination character on writes (you can set that with a VISA property node) and that you are sending the correct termination character. The default is 0x0A (newline).

Problems with access to serial port using reentrant code

Hi,
I have a VI that send commands and receive answers from an instrument using
de serial port.
This VI runs perfectly when used alone.
However I'm trying run two instances of that VI simultaneously using
reentrant code and I'm facing some problems.
Sometimes everything is OK but sometimes, in the process of writing to
serial port the following error happen:
Error code 36.
Invalid refnum device.
What is this?
Does someone know how to prevent this?
Thanks in advance for any help.

You can't use reentrant vi's vith serial vi calls without supervising of
driver.
Use VISA instead and you have to control the VISA session opening and
closing. Another word is that the only one serial port sess
ion should be
opened at a time.
Reentrant vi's for serial port without checking serial port session is a
mistake of program algorithm. Change it in any convenient way.

Newbe question about SG300-20 dropping port to Router

Hello to you all
Today I received my new SG 300-20 managed switch to replace an unmanaged switch with some faulty ports.
I want to use it in a a combined Home / Small Office environment. It is my first purchase and use of a managed switch so am still new at it.
I come from an IT-background but more from the software side than the hardware side of things, but I feel comfortable with hardware and network things.
I was planning to start using the switch in its most basic configuration first and gradually start learning the finer details of its configuration, with the ultimate purpose of setting up several VLANs for business, private use and media playing and to do some IPv6 experimenting.
All my attached devices are Gigabit network capable.
The issue is when connecting the cable to my router (an ISP provided FritzBox 7340 (an ISP version comparable to 7390) which is IPv6 capable) the SG 300-20 keeps dropping the port.
The log show the following messages repeated 3 times:
2147483597   2011-Mar-18 17:08:53 Warning   %LINK-W-Down: g8
2147483598   2011-Mar-18 17:08:50 Warning   %STP-W-PORTSTATUS: g8: STP status Forwarding
2147483599   2011-Mar-18 17:08:46 Informational   %LINK-I-Up: g8
It doesn't matter which port I use the same thing happens each time.
All other devices connected to the SG 300-20 just work fine.
When I connect the router to my old switch it also just works fine.
When I connect my old switch with router attached to the SG 300-20 it works fine and the DHCP on my router will provide the SG 300-20 with an IP-address.
I just can't connect the router directly to the SG 300-20.
I'm a bit at a loss of where to look for a solution.
As I said all is still in default settings.
Can anybody point my to a solution or way of finding out what is the problem why the port is being dropped?
Thank you
Alwin

This is a gateway device.....also known as a modem/router. It combines the functions of a separate modem and router in one package.
The Q1000 is the main router on your network, so any port forwarding (Apple calls it Port Mapping) must be done on the ActionTec device.
The Time Capsule is in Bridge Mode. In this type of setting, all ports are automatically already open. So, there is no need to "open" a port that is already "open".
The Time Capsule will simply pass through any information that it receives from the ActionTec gateway to other connected devices on the network.
