10/100 ports stop forwarding on Cat.4506 SupII Cat7.6.7
On one location of our campus various 10/100 ports stop forwarding traffic after some time (port stays in notconnected state, sometimes with linkled on, sometimes off).
This happens on various ports of both Cat.4506 systems on both line-card types:
WS-X4232-GB-RJ
WS-X4148-RJ
We already replaced linecards, without succes.
Does anyone know what's wrong ?
Peter,
You would probably have a better chance of getting a solution to this issue by posting on the LAN switching forum.
Hope this helps,

I used to use port 8001 for a lot of things. Recently, the port stopped working. I triple checked all my router settings and port 8001 is still forwarded. I tried other ports. I rebooted. I tried shutting off my firewall. Nothing worked. I really need a port working for various things so I need some help. Tell me if you need any additional information and I'll tell you. Does anyone know what I should do??
Well, I did everything you said and I'm sure I did it right. No luck. I have a feeling that something else is going on here, but I'm not sure what I should do. Anyone have any ideas?

Problem with Port Range Forwarding WRV54G
I have configured my WRV54G to do the following, in this order, on the Port Range Forwarding page of the router:
1. Forward port 3389 to LAN Static IP x.x.x.100, a desktop PC. I have confirmed this works, a port scan shows this port is open and I can remote desktop into x.x.x.100
2. Forward port 443 to LAN Static IP x.x.x.101. I have confirmed this works, a port scan shows this port is open I can VPN to an SSL concentrator at x.x.x.101
3. Forward port 3390 to LAN Static IP x.x.x.102, a desktop PC. THIS DOES NOT WORK. A port scan shows that this port is not open. I have configured the remote desktop host at x.x.x.102 to use port 3390. Netstat shows that x.x.x.3390 is listening on this port. I can remote desktop to x.x.x.102 from inside the LAN, no problem, so it's not an issue with the PX configuration.
So, then I switched the order of the port forwarding instructions, in this order, as follows:
1. Forward port 3389 to LAN Static IP x.x.x.100, a desktop PC. I have confirmed this works, a port scan shows this port is open and I can remote desktop into x.x.x.100
2. Forward port 3390 to LAN Static IP x.x.x.102, a desktop PC. I have confirmed this
works, a port scan shows this port is open and I can remote desktop into x.x.x.102
3. Forward port 443 to LAN Static IP x.x.x.101. THIS DOES NOT WORK. Port scan shows this port is not open.
It looks like the WRV54G is only recognizing the first two entries in the Port Range Forwarding table and IGNORING the third entry. HELP??!!
I have the latest firmware installed: v2.39.2e
Anyone have a solution? Thanks in advance!
Message Edited by crescendi on 07-19-2008 11:53 AMAre you still using the DHCP server range of x.x.x.100 through x.x.x.149 ? If so, then your problem may be that you are using illegal fixed LAN IP addresses.
With Linksys routers, any fixed LAN IP address must be outside the DHCP server range, and it cannot end in 0, 1, or 255.
I would suggest that you fix the illegal addresses, then see if that resolves your problem.
Here is the full set of rules for using fixed LAN IP addresses:
With Linksys routers, a fixed (static) LAN IP addresses must be assigned in the device that is using the address. So you need to enter the fixed address in the computer or printer, not in the router.
When using a Linksys router, any fixed LAN IP address must be outside the DHCP server range (typically 192.168.1.100 thru 192.168.1.149), and it cannot end in 0, 1, or 255.
Therefore any fixed LAN IP address would normally need to be in the range of
192.168.1.2 thru 192.168.1.99 or
192.168.1.150 thru 192.168.1.254
assuming you are still using the default DHCP server range.
Also, in the computer, when you set up a static LAN IP address, you would need to set the "Subnet mask" to 255.255.255.0 and the "Default Gateway" to 192.168.1.1 and "DNS server" to 192.168.1.1
It is also important that no two devices on your network be set to the same static LAN IP address. -
WRT54GC resetting Port Range Forwarding
I have a WRT54GC, with firmware v1.05.7. And I have recently modified the Port Range Forwarding. It will work OK for a day or two, then for no reason it stops working. When I check the configuration, I see it has reverted to the old Port Range Forwarding config. So I change it again, save it, and again it will work for a day or two before reverting to the old config. How can this be happening?
Hey try resetting the router reset button in such a way that power light is blinking on the router & then do a complete network power cycle i.e., unplug the power cables from the modem & from the router & then plug in the power cable to the modem first once all the lights are solid green you could plug in the power cable to the router & check out it will definately work!!

ASA appears to randomly stop forwarding/routing traffic
Hi guys, got a curly one -
Our ASA appears to randomly stop forwarding traffic between interfaces. Traffic does not forward for several minutes, then it starts again. After a while the traffic stops again for a few minutes, and the cycle repeats.
If you are on a directly connected network you can still ping the ASAs local interface (I have ICMP turned on for testing). However you cannot ping the ASA from any remote network. I can ping or trace all the way up to the last hop without an issue. You also cannot ping across the ASA to servers on the other side, even from the immediate next hop (which as I mentioned above, still works) .
This would appear to point to a routing problem? Strangely, routing still functions for the management network - I have had no problems reaching the command line from elsewhere in the network.
Has anyone encountered something similar to this before?
Relevent ASA configuration commands below:
interface GigabitEthernet0/1

MDB and Database - Listener port stops working
Hi,
I have created an MDB which does the following when a message is received from the queue.
1. Store message in database
2. do some processing
At step 1, if there is any issue with the database connection (e.g. database is not available etc), I rollback transaction. My idea is to leave the message on queue for now and retry it again after some time unless the database is back again. "Maximum retries" of the listener port is set to N but since there is no retry interval available, all N retries are done in a flash and my listener port stops working. I cannot use backout mechanism as I have to wait for the database to be back again. What are my options?usmanchaudhry wrote:

a simple JDBC rollback won't do it.

HP Pavilion dv6 All 4 USB ports stopped working
Hello,
I recently bought a Pavilion dv6-6c11sa laptop. Windows 7 Home Premium 64-bit
Everything was working fine for about a week, and then yesterday all of the USB ports stopped working. I have 4 USB ports in total, two 2.0 and two 3.0. No matter what peripheral device I plug in, mouse or flash drive etc, they're not recognized by the laptop. The lights don't even light up on the devices, regardless of the port. I've tried uninstalling and reinstalling the drivers in device manager, taking out the battery and rebooting, installing the chipset drivers (AMD), nothing works. No programs had been installed 3 days prior to the occurence, although I had rebooted several times in that time frame. I simply booted up the laptop yesterday, and nothing worked.

USB Ports Stopped working on MacBook Pro 13-inch, Late 2011, OS X 10.8.5
Please help with any advice
I have OS X 10.8.5
One USB port stopped a while ago
The other stopped yesterday.
I have reset the PRAM
I have also reset the SMC
Nothing seems to fix it.
I do have a time machine backup
Any suggestions?The best option is a visit to the Apple store genius bar for a FREE evaluation. You have tried all you can.

A barcode scanner that was connected directly to the Mac's USB port stopped working as the "USB had too much power drawn", even though it has worked for over a year in that port. When we plugged it into the port on the keyboard, the device works. Why? Obviously the device is operational. Could the USB port have burned out from having too much power drawn? If so, is it reparable?
It can't draw "too much" power, it can only draw as much as the USB port is able to provide and no more. IIRC, the keyboard port has a lower power output than the iMac's port.
That being said, yea, it's possible that the port has failed and it can be replaced or if another port works you can use that one. Although if it is still under warranty or covered by Apple Care, then I would take it to an Apple Store or service provider to get the port repaired. -
Unable to Save in Port Range Forwarding
I'm using the BEFW11S4 wireless router and am unable to save the new port range forwarding settings I have entered. Everytime I click Save Settings, I receive a box which reads:
"The server 192.168.1.1 at Linksys BEFW11S4 V4 requires a username and password.
Warning: This server is requesting that your username and password be sent in an insecure manner (basic authentication without a secure connection)."
When I enter the same u/p that I used to access the router in the first place, it rejects and keeps bringing up the log in screen.
I cannot get the port range forwarding to save at all due to this.
Does anyone have any suggestions?
Thank you!try remembering the password you used for first time while installing the router .... if not then use default password admin with out any username ....
If still not working then you need to reset the router .... -
Router won't save settings of Single Port Forward or Port Range Forwarding
Hi everyone, I'm having a bit of trouble tonight trying to get my Playstation 3 to play games online and in doing so I'm attempting to enable Single Port Forwarding and or Port Range Forwarding.
To start, I am using this link below this paragraph as a guide.
http://portforward.com/english/routers/port_forwarding/Cisco/Linksys-E1000/PS3_Endless_Saga.htm
Each time I go and set the settings and click save, it tells me the settings have been saved successfully then when I click continue onto the next page it shows they actually haven't saved at all. My router is out of it's 90 day phone support with Linksys and I refuse to pay anything extra for support so I'm hoping someone else will be able to help me with my issue since they refuse to unless I pay them.Hello. Sucks you ran into trouble just after PSN got back online

What ports to forward to server for mail to function correctly?
I recently upgraded to Mountain Lion form lion and am experiencing a MAIL issue (FAILURE)
I beleive I need to restablish or open ports on my router but the common ones don't seem to be doing the trick for users using Outlook. I have the Apple document that talks about the most common used ports but my Netgear router limits me to 20 so I need to narrow down the selction a bit.
Any assistance would be appreciated.
Right now, these are the ports being forwarded: (and yes, many can be eliminated)

192.168.15.101Regarding Outlook. Can it receive, send or neither?
If the problem is sending, two things to look at.
- You are configured for port 587 which is TLS.
In outlook, select TLS (not SSL)
I prefer to enable port 465 which is SSL, this plays well with outlook.
To do so, you need to edit
/Library/Server/Mail/Config/postfix/master.cf
Look for these lines
#465 inet n - n - - smtpd
# -o smtpd_tls_wrappermode=yes
# -o smtpd_sasl_auth_enable=yes
# -o smtpd_client_restrictions=permit_sasl_authenticated,reject
# -o milter_macro_daemon_name=ORIGINATING
Uncomment them all. DO NOT remove the space before the -o (its required)
Then issue
sudo postfix reload
Make sure 465 is open in your router
Retry Outlook
587 = TLS
465 = SSL
- Look at your smtp logs, do you see helo errors when you try to send from Outlook?
If so, do this (good idea to do this for ANY installation)
edit
/Library/Server/Mail/Config/postfix/main.cf
Find
smtpd_helo_restrictions = reject_non_fqdn_helo_hostname reject_invalid_helo_hostname
Change to:
smtpd_helo_restrictions = permit_sasl_authenticated permit_mynetworkseject_non_fqdn_helo_hostname reject_invalid_helo_hostname
Then issue
sudo postfix reload
If this doesn't solve the issue.
Please post whether this is a receiving or sending problem.
If receiving, post output of mailaccess.log(imap) log when you attempt to pickup mail
If sending, post output of your mail.log(smtp) when you try to send.

I am a little confused on which server i need to forward the requests to on our sonicwall firewall. I followed this:
http://thewolfblog.com/2014/02/08/deploying-a-2012-2012r2-remote-desktop-services-farm/
just so you know the exact configuration. Basically, 2 separate session host, 2 separate brokers and 1 gateway (running web access). I know this has something to do with the correct ports being forwarded as it works perfectly inside the LAN. I have the requests
forwarded to the gateway now and when i go to https://FQDN/RDWeb, i can login and see the published apps. Its when i click one of the published apps that i get this:
In the present config, what private ip am i to forward to?So i actually had to remove the rdweb server from the deployment and add the rdweb access role to the gateway server to get this to work. Doesn't that defeat the purpose of having a gateway server in the first place?
Hi,
There is nothing wrong with having RDWeb on the same server as RD Gateway if you want. RD Web is in essence a method to deliver .rdp files to end users.
If you want to have RDWeb on a separate server you can. To do this you would need to use an additional public ip address, or perhaps a reverse proxy. For example, you might have gateway.domain.com pointing to the public ip for your RDG, and remote.domain.com
pointing to the public ip for your RDWeb. On the firewall you would have TCP 443 and UDP 3391 forwarded for gateway.domain.com and only TCP 443 forwarded for remote.domain.com
I was wanting to use the gateway server as the only one exposed to the internet. Is there a way to do that and have the gateway server connect to the rdweb server? And without access to the rdweb we would not be able to use the rdweb feed, right?
Maybe you are looking for
