Cisco Switching/Routing :: Output Errors On N5k 10G Interfaces?

Jan 9, 2012

today I witnessed a cisco n5k that stopped playing fair. For a yet unkown reason several interfaces started to show output errors all begining within the same second. While i instantly thought this would be a wiring issue I began to ask myself what an output error actually means. Google usually brings up output drops, not regular output errors. So what is it and how can a 10G fiber interface even detect that there is a problem without receiving what it was sending?

Cisco Wireless :: AP1242 Excessive Transmit Discards And Performance Complaints

Apr 15, 2013

I have an AP1242 near a couple of conference rooms.  I get complaints when we have a large contingent in there and some try to download documents.  The bandwidth consumption is meage - less than 2Mbps.  But there could be say 50 people in those training rooms.  I see no errors at the FE interface on the AP but I do see a good number of Transmit Discards.
Are 50 users connected to an AP1242 simply more than should be expected of the device?  802.11g is the radio.
Are transmit discards indicative of some kind of configuration problem?  The users in these cases are generally very close to the access point - within a few feet even.
If it is indicative of a configuration problem would that be an issue of the configuration of the laptop wifi cards or a problem at the AP?

Cisco Switching/Routing :: 6513 - Transmit Discards On Certain Interface

Feb 25, 2012

We have a Cisco 6513 Switch.  During some parts of the day it is having large amounts of transmit discards on a certain interface because of the amount of data we are pushing.  We have determined it is a link problem and not a problem with the switch.  The link cannot handle the amount of packets the switch is pushing out.  I was wondering if there is a way to create a buffer or a way to regulate the maximum amount of packets that can leave that interface without losing any packets?

Cisco Switching/Routing :: 3750 Priority Queue Out Transmit Discards

Dec 13, 2011

After opening up Solarwinds NPM, I noticed that a few of my interfaces had lots of discards (who knows how long it's been sets the counters were reset)
interface GigabitEthernet1/0/25description Etherchannel to MamaCassswitchport trunk encapsulation dot1qswitchport mode trunkswitchport nonegotiatepriority-queue outchannel-group 4 mode on
interface GigabitEthernet2/0/25description Etherchannel to MamaCassswitchport trunk encapsulation dot1qswitchport mode trunkswitchport nonegotiatepriority-queue outchannel-group 4 mode on
interface Port-channel4switchport trunk encapsulation dot1qswitchport mode trunkswitchport nonegotiate,It looks as if priority-queue was configured outbound on these interfaces, could this be the cause of the transmit discards which are now up to 79,835, I just reset the counters on the interfaces a little while ago.
I'm not the best in the world when it comes to QoS, we do have some VoIP phones, but they are only a specific network, and do not travel outside, since there are used mainly for VoIP training. I do know both interfaces are running the default of FIFO.

Cisco Wireless :: 5508 - Virtual WLC - Certificate Errors

Cisco Wireless :: 5508 - Mobility Ping And SSH Errors After Upgrade To

Aug 7, 2012

After upgrading my 5508s to, they are reporting mobility data path errors to one of my WiSMs running
I get these messages on the 5508s reporting that it can't send a ping to the affected WiSM:
*ethoipSocketTask: Aug 08 21:15:41.175: %ETHOIP-3-PKT_RECV_ERROR: ethoip.c:341 ethoipSocketTask: ethoipRecvPkt returned error
*ethoipSocketTask: Aug 08 21:15:41.175: %ETHOIP-3-PING_RESPONSE_TX_FAILED: ethoip_ping.c:312 Failed to tx a ping response to <ip address>, rc=5
But maybe there is another clue because I also see in the same log these errors referencing the same WiSM:
*bcastReceiveTask: Aug 08 21:15:45.310: %LOG-1-Q_IND: mm_dir.c:1969 Failed to recreate the SSH Rule for <ip address>.
*mmSSHPeerRegister: Aug 08 21:15:44.829: %MM-1-SSHRULE_CREATE_FAILED: mm_dir.c:1969 Failed to recreate the SSH Rule for <ip address>.
Why is the controller trying to SSH to another controller?  Was some SSH related feature added to 7.2 that has been accidentally enabled?

Cisco Wireless :: WLC 5508 Centrally Switched Client Errors

Aug 16, 2012

I am having trouble with a newly configured install.  Basically it seems that my centrally switched guest SSID is not functioning.  As you change AP groups, which should change the interface associated with the SSID and also the dhcp client address, the client is retaining the original dhcp address from whichever AP group they first associated with. 
I also have a locally switch WPA2 SSID at each location which is working fine.  Clients are able to change dhcp address correctly as they move between AP groups.  It just doesn't seem to be working on the guest network, which is odd because it was working earlier in the install.  It has only started having issues yesterday afternoon. 
The interface above is assigned to the guest SSID in one of the AP group.  I assume this has something to do with it but I've been over my DHCP assignments on the core switch, local switch, controller, and dhcp server and can find no issue with the configuration..
 I am not sure why as I am not using DOT1X at all.  The guest is a pass-thru and the WPA2 network is just WPA + WPA2 with TKIP and AES.  No DOT1X anywhere on the controller...

Linksys Wireless Router :: Weird WRT54G2 Errors False Disconnects

Nov 24, 2011

I am directly plugged into the router on my computer, and it is used wireless for the rest of the computers in the house.  Frequently (3-4 times a day usually, sometimes more like every 20 mins, other days not at all), the router and Network Magic will tell me my computer has lost internet connection, and browsers and any program I try to start won't be able to connect to the internet.  However, I know the connection is still live because any program that was running and accessing the internet beforehand (multi player games and instant messaging programs, for example) still run fine with their connection and I can continue to play or chat online until I close that program.  
Trying the 'Repair Connection' on network magic doesn't work, but unplugging and replugging the power cable to the router fixes the issue(again, so I know it's the router and not the internet)whatever reason the router is deciding to tell me it's not active and refuse access to the internet for new programs when existing connections don't show any problems.

Internet Intermittently Goes Down / DNS And IP Conflict Errors

Jul 10, 2012

[code] Whenever I am browsing online, every once in a while the internet just cuts out. It still says I am connected to my wifi network, but there is "limited or no connectivity." Whenever it happens, everything on the network loses its internet at the same time. In the household, there is one PC (mine), one Mac (my wife's), one iPod touch, and 2 iPhones that all connect to the wifi. The vast majority of the time, when this problem occurs, simply unplugging the router and then plugging it back in fixes the issue.Sometimes however things are different. Especially lately, I sometimes get an "IP conflict" error message. It says another device on the network is using the same IP address. Sometimes with this error simply unplugging and replugging in the router works. Sometimes the router has to be reset twice before things start working again with this error. The error doesn't happen every time the disconnect occurs, but it seems to be getting more frequent lately.Sometimes the disconnect happens when I am playing an online game that requires a constant connection to the internet. Sometimes this goes as usual, where a single router reset fixes the problem. However, sometimes this situation gets more complicated. One game in particular (League of Legends, if it matters) has this problem all of the time. When the internet disconnects while this game is playing, I do not get the "limited or no internet" warning. Instead, the computer seems to think that it is connected, and that the internet is working.

During this scenario, resetting the router once is never enough. After resetting once, the wifi reconnects and now it realizes something is wrong. After the first reset, the computer seems to "realize" something is wrong after all, and I am connected to the network but this time with the "limited or no internet" warning. A second router reset after this usually fixes the problem.Last night the worst disconnect happened yet. It was in the middle of a game, and the internet cut out, with no warning on the network. After one router reset, the wifi network reconnected immediately with an "IP address conflict" error, and then I was connected with "limited or no internet" on the network. I did the second router reset as usually required, but nothing happened. After a second and a third reset, there was still a permanent "limited or no internet" warning.I tried hardlining in directly to the modem and there was still no internet. Running the network diagnostic on my laptop fixed it however and I was connected to the internet. However, wifi still would not work, even after trying the diagnostic again. Running the diagnostic came up with an error that the DNS server was not responding and so nothing could be done.This time I reset everything. Unplugged both the router and the modem and left them unplugged for 30 minutes. When I turned everything else on again, same issue. Connected to the wifi network, but "limited or no internet." I unplugged everything again, left them overnight, and this morning after plugging everything back in the internet was back.A few final points I think might be relevant:

1) When checking the system event logs, it's usually a DNS error that I get (see event logs, 1st attachment).
2) This disconnect error seems to be more prevalent when more devices are on the network. As I said, they have gotten more frequent lately, especially the IP conflict warnings, since the 2 iPhones were added a few weeks ago. 5 months ago when it was only my PC on the network, these issues were practically non-existent.
3) It's a Belkin wireless g-plus router. Model # F5D7231-4 version 1213. It is an older router.
4) This has been happening for almost a year, but just recently gotten so bad I have to get this fixed, especially after last nights that could not be reset no matter what.
5) I'm not sure the disconnects have ever happened why the PC is not connected. That may not be relevant however, because my PC is almost always on since I work from home, while the iPhones, iPod touch, and my wife's Mac are only connected periodically.
6) This error has occurred while my PC is the only device connected to the wifi network, but it seems much less frequent.
7) The time the error seems most likely to occur is when another device connects to the network, such as when my wife first gets home from work. This is not exclusive however, and the DC's can happen at any time.

I've seen that people want ping tests and ipconfig /all tests so I will post mine. I will edit my post with the same tests done the next time this dc happens. I've also included a screenshot of that xirrus wifi program. [code]
