Cisco Infrastructure :: 802.1d - Can A Designated Port Send A TCN
Nov 25, 2012Which ports does send TCN inside the network? Only the Root Ports?
If one switch has his root port down, will it send TCN for his designated ports?

Currently it seems as our 3550's doesn't send traps when bpdu-guard sets a port in err-disable state. Or DFM doesnt recognize it.Is there a way to get a DFM alert when a 3550-port gets into err-disable state?
View 2 Replies View RelatedI have two WS-X6148-45AF linecards here that have been out of use for quite some time. Upon inserting them in one of our 6509-E's I noticed that both had "Minor Error"s on their module diagnostics.
I would have just assumed that the cards were dead and requested replacements, but both cards have the *exact* same diagnostic errors, which only seem to effect every-other port. That's too much of a coincidence for me, so I figured I'd ask on the forums and see if I'm just missing something obvious before I assume the worst. Are these cards both somehow damaged in the exact same way? Or is there some config/compatibility issue that I haven't heard of?
relevant diagnostic output from one of the cards (Both outputs the same, no use posting twice) is below:
Router#show diagnostic result module 4
Current bootup diagnostic level: minimal
Module 4: 48-port 10/100 mb RJ45 SerialNo : SAL11391VUY

We are trying to install filter software at our main location and branches. The admin console has been installed at the main branch, but I need to allow access to ports 58000-58003 through our firewall in order to successfully install the software at our branches.

There are many gamer users, and they complain that Call of Duty Modern Warfare 2 sees our network as "strict NAT", while for full gaming experience it needs "open NAT". After a small research I have found out that CoD needs certain port ranges to be forwarded to LAN IPs. Well, I know how to forward a range of ports to a single IP, but how is it possible to forward a port range for all the IPs in the LAN?
View 1 Replies View RelatedI need to increase the link capacity of 10GE to 20GE between two Cisco7609, so I feel the need to configure port channel between them, my little problem is that I have a SCE 8080 in the middle of both 7600 currently is configured inline. The SCE has 4 modules 1X10GE-L-V2 (currently in use 2), I was investigated and the truth is that I not found anything concrete about how to configure the SCE to "pass" etherchannel through it? What the SCE needs to support 20GE of traffic? (configuration and software)
I have two 10GE ports available on the SCE
We have a 6509 running 5.4(2). We have set up a hyperterm session and connect to multiple devices, then we get to the 6509 and it will not work. When we reload the 6509 and we are consoled into it, we get data until it is finished reloading. Then the console connections is no longer there.

Just want to ask if 4-port serial HWIC-4T is compatible for the Cisco 2801?We need additional HWIC for Fast Ethernet but the problem is we don't have already slot for it.We already have two HWIC-2T 2-port serial which is inserted at slot 1 and slot 3. We're planning to buy 4-port HWIC-4T so we can use the slot 3 for HWIC Fast Ethernet.if it's possible to have the 4-port serial HWIC-4T be inserted to Cisco 2801.
View 1 Replies View RelatedI used to be able to set an uplink port with the interface command "port network" so that it would not learn all the mac addresses that are being flooded down to the switch. It does not seem to be there on the 2950's or 35XX switches.
Where did it go and what is replacing it? Interface is a Trunk port as well.
We are going to "publish"(I don't know if this is correct word to use;)) our mail server on Cisco 2921. As far as I know it can be easily achieved with static NAT. But the thing is, we don't want to publish it on standard 443 port i.e. we want router to listen for https connections on other port than 443, and then redirect this connection to internal server with private ip.

View 2 Replies View RelatedI got a new router yesterday and I'm trying to re-portforward a server that I was hosting. I access my router page and add the ports to the port triggering page and it saves. After that, I go and check if my ports are open, but it is still saying that they are closed. The protocol is set at TCP. However, on my old 2WIRE router, I used to be able to set the application type as FTP. But theres no option to do it on this one.
Everything worked fine before on my old 2WIRE router. Also, if it makes a difference, I'm using the Windows 8 developer preview. I'm not sure if this would be the problem, but I also tried adding a port exception to the firewall but can't find the option to do so.

View 9 Replies View RelatedI am having almost an Identical issue. It seems that I can do anything I want on the internet, but the second I open hotmail all the problems start. Issues occur on both FF and IE. As with you I am able to continue to get some information on sites that are currently open (for example I will get incoming IMs, although I cannot send replys, and my stream on facebook continues to update). Once this happens I cannot open any new webpage or use the wireless on ANY other device in my house (iphones and printer); wired devices seem to have no issues. I have done everything as far as resetting, updating firmware etc to my router with no luck. I have a netgear dual band router, computers with Windows 7 64bit. It seems that accessing Hotmail on the iphones does not trigger the same issue...
