Cisco Switches :: Strange Network Standstill SG-300?
Dec 20, 2011
we have a production network that uses five SG300 switches that functions brilliantly most of the time. four of our switches run in layer 2 mode and the last switch runs in layer 3 as it is used to route our 7 vlans as well as routing traffic between our two gateways. the switches use the original firmware that shipped with the devices (v1 device) and will be upgraded within the next week. the problem that we have is that the network seems to stop routing for all of the hosts after a given time. the only way to fix this issue usually is to reboot the main layer 3 switch. the main layer 3 uses a default route to one of the gateways and a return route has been applied in the gateway. the only thing i can think is that somewhere one of the devices routing tables become full and the network stops responding.

Last week and just yesterday, our switch SG200 50/50 logged an error like this:
%CDP-E-MALFORMED_TLV: CDP message from 88:43:e1:ab:66:f8 cached with illegal Appliance VLAN-ID TLV
At the time of the error, the SA520 router's LAN Port 1 where the SG200 Port 49 connected went down. (Light is OFF) So internet is down and other V LAN are disconnected. The MAC address on the log is the SA520 router. This happens 2x now and it needs for me to reboot both switch and router. and goes back again online.
SG200 50/50 Port Firmware 1.1.1.8
SA 520 Firmware (Primary/Sec):2.1.51/2.1.18

I have an ASA 5520 with 2GByte RAM running Software Version 8.2(4)4.
As soon as I enable outside interface Gi0/0 I get the following error message on the console every now and then:
(set_exptime) Timer not a leaf 0x714644dc. Traceback: 0x805e4b3 0x8061b92 0x855ce33 0x85606e7 0x85634ee 0x8563f53 0x8564664 0x8564a12 0x85623a5 0x8063b63
mgd_timer_set_exptime: Not a leaf called from 0x855ce33
I have configured a second 5520 as failover mate and once I have activated the failover device and the configuration replication was finished this second device started the same tracebacks immediately.

The issue that I am having is that the network cable I have that going from my router to my desktop computer, seems to be flaky, at least it seems that way...When I try to use the network cable that goes into this desktop, into another computer(one that I know works), the connection status alternates between connecting, and no network cable detected, connecting...and no network cable connected, and so forth.it NEVER connects. When I plug the cable back into the desktop, it does the same thing for maybe a minute, but then eventually connects. However, every other computer, laptop, macbook, another desktop PC, that I have tried connecting using this same cable never connects.

My desktop PC has occasional hiccups in which I can't connect to any website (via any browser, I've tried Firefox, Chrome, Opera & IE) for short periods of time (usually ~1 minute) but all other Internet connectivity seems to be normal. (I can ping Google for instance, and I remain connected to Google Talk, but I can't load the Google website.)
I recently did a fresh install of XP Pro SP3 and am pretty confident that there is no malware running on the system. (I'm running Microsoft Security Essentials and Windows Firewall but I also did a Malware Bytes scan which uncovered nothing.) The desktop is connected wirelessly but I don't suspect an issue with the router because my laptop (via wireless) and my girlfriend's desktop (via wired) can surf the web just fine when my computer is experiencing issues.
I checked for proxies (both in the browser settings and in Windows settings) but everything appears to be setup correctly (that is, unproxied.) DNS is set to the proper DNS servers for my ISP (Cox) but I also tried switching to Google's DNS servers with no luck.

My Wi-fi on my rig seems to have some odd problems. When I'm gaming i often get a lag spike every 10-20 second or so, and before I got the "Vista anti-lag" program I was also getting the enormous 60 second lag spike. I'm sure many Vista users recognize this problem. But here is the deal, the first kind of lag spikes completely disappear while talking on Skype! Which makes me wonder, what is it with Skype (only while talking) that removes the lag? Gaming with Skype makes all games run fluently without any spikes at all.

Basically I started disconnecting when I logged onto Blacklight Retribution after a recent game patch, after a few days the problem stopped and I was able to play again (with no changes to my computer) a few days later another patch was added and the problem occurred again, at first I thought it was a Blacklight specific problem (as this was my only installed game) however i installed a few other games (Kabold Online, Perfect World, Forsaken World, TF2, MW2 and C9) and I got the same problem on each of these games. I haven't been able to log onto a single Online game for more than 5 minutes, normally I'm disconnected at login, HOWEVER, my internet works completely fine in for everything else, i can browse the web, download game clients etc with no problem whatsoever.(Forgot to add, When i disconnect my LAN Cable mysteriously Unpluggs itself (according to computer) and a disable/enable in network manager reconnects it)
- Checked to see if drivers were up to date (they were)
- Rolled back NIC Driver (and put it back when this didn't work)
- Checked device manager for any problems with my NIC, (working as normal apparently)
- Tried setting my NIC to 100mbps Full Duplex
- Setting my power options to not interfere with NIC
- Had a DHCP error in my event logs so i set my gaming machine to a static IP
- Turned of UnUP, Turned on DMZ
- Turned off "Green Ethernet"
- I had other Errors in the form of a service stopping my NIC
- Phoned ISP, Everything is OK there end but they sent out a new router, but problem still occurs
- Noticed that a service was sending a stop control to my NIC, looked on forums for fixes and applied several of them
- Reformatted computer with old XP (switched from windows 7), updated, installed latest drivers etc and still same problem except now I don't get anything in event viewer when the problem occurs.
The only thing i haven't tried is replacing my NIC, but considering the internet works completely fine for everything but Online games I'm unsure how this could be the problem.

we recently updated all of our WLC's to 7.098 and it all went smoothly, controllers rebooted and AP's updated their firmware and rebooted OK.One WLC (4402) which was working fine since the update now has no AP's associated. The AP's were all configured to run in HREAP mode and are on remote sites within our WAN. I have checked that all policies and ports are still open (none have changed anyway) but the AP's can not join with the contoller.The log from an AP trying to join with the WLC.

I'm having the following issue with a couple of 1231's.
Some overall config info first:
This is a small office with 2x Catalyst 2950 (24-port, no PoE) switches and 4 AP1231G (autonomous). The APs get PoE from a PWRINJ3 each. The injectors are powered by the AP power supplies. Injectors and power supplies are mounted in the patch closet.
The 2 switches are connected together over 4 ports (20-23 on each switch), these ports are set to 1Q Trunk mode.
The APs are connected to the switches, 2 to each switch, on port 1-2. These ports again are configured as 1Q Trunk.
APs are connected to the switch as follows:
[switch] <- patch cable-> [injector] <- patch cable -> [patch panel] <- static cabling -> [outlet] <- patch cable -> [AP]
All this has been working without problems for a number of years.
A few weeks back, AP2 did not restart after a power cut (everything else did). All LEDs are off, port on switch has no LEDs lit. I did not get around to investigating this furtehr until last week. I unmounted (failed) AP2, took it to the spot where (working) AP3 hangs, and plugged it to the cable of AP3. AP2 came to life immediately. I unplugged it and plugged AP3 back in, which restarted immediately.
So I suspect a power supply issue on AP2. I took the injector and power supply that fed AP2 out of the patch closet. When connecting AP2 directly to the power supply, it came to life immediately. So I figure the injector is defective.
On the same day, I notice AP4 is also dead (again all LEDs off, no idea how long, could have been that day or could have been a few days - it has definitely been working after the power cut that appeared to have killed AP2).
So I order 2 new PWRINJ3s and for good measure 2 new power supplies. Later that day, I took the injector and power supply that fed AP4 out of the patch closet. When I try this combination (AP4, injector4 and P/S4), and connect it to a different wall outlet (and therefore a different port -16 - on the switch) IT WORKS! Should have triggered questions, but did not immediately.
Last Thursday I got the new injectors and power supplies. So I take one of each, hook them upto AP2 at my desk, and AP2 starts up. So I mount new injector2 and new P/S2 in the patch closet, put AP2 back in its place, connect all the cables - NOTHING. AP2 does not start. The "power" LED on the injecvtor lights up green, the "device status" LED remains off. I take AP2, new injector2 and new P/S2 to my desk, hook them upto a wall outlet (connected to switch port 17). AP2 starts immediately.
Meanwhile AP3 has (also) stopped working (no LEDs on at all). As far as I can tell, it stopped working after I briefly disconnected (and reconnected) the patch cable between injector3 and the patch panel in the patch closet. The LEDs on switch port 1 are off.
I have since tried to power cycle both switches (took power off both, waited a while, poewerd both back on). No change.
PS: the APs ran firmware 12.3(8)-JA until recently. AP1, AP3 and AP4 were upgraded to 12.3(8)-JEE after the the power cut that took AP2 out. THis is when I found out AP2 was dead. AP2 was still on 12.3(8)-JA. It was upgraded to 12.3(8)-JEE last week when it was on direct power on my desk.

Our costumers has implemented 2 AIR-WLC4402-50-K9 with Software Release 7.0.98.0, the wireless infrastructure consist in 2 Root-Mesh-LAP and 8 Mesh connect over-the-air to deploy outdoor coverage.
All the LAP are Aironet 1520 Series Mesh Access Points with equipped with 3 antennas for 2.4GHz and 1 antenna for 5GHz (backhaul).For one year all seems to be ok, yesterday after a power outage of one Mesh-Root-LAP, 5 Mesh-Lap continues reload each 10-12 minutes, on the WLC Log you can see event like a reboot from AP Console, on the LAP console i can capture this event before the reload:

What does it mean? That the beacon signal trasmitted from Root-Mesh-LAP cannot reach the Mesh-Lap and so the Mesh-LAP force a reload?Where we should search the cause? In the power instability or in a interference on the 5GHz radio interface?

we want to replace our 1242 AP's with the 1602 model and so far everything works like a charm. We have just noticed, that most of the clients which are connected on the 5GHz N radio, the web interface of the AP1602 shows his own host name instead of the clients host name.
For example:
Radio0-802.11N2.4GHz
SSID INTERN :
[code].....
The Host name of the 1602 is "AP-LABOR", so why it shows the own host name for the Dell E6420 Notebooks on the 5GHz radio and on some "NONE"?

I've a WRV210 Wireless-G VPN Router with RangeBooster, that logs this alert almost every time, "Packet type : 0 -- free socket buffer only".Also each time that some devices, like Android, are connected to the Wifi, the wifi starts a reboot and drop cycle.
Some extra context information, I've connected to the router a Cisco Gigabit switch and all the wired devices are connected to the switch, that could overload the router? Other point I've a Cisco VOIP gateway connected to the router and a few VPN's and firewall rules setup.

I have searched the forums, and can see that I am not the only one with speed problems on this router. When I changed from a D-link dir-615 (yeah, no wonder I changed it ) my download speed dropped from 4-5 MB/s to 1,3 MB/s. I'm using a wired connection. Have tried disabling QoS in router settings, did a firmware upgrade, reset the router. You see, when I do speed tests on the internet I get 40-50 mbits download, 25-30 mbits upload. I have tried many different files to download, both torrents and through my browser.

I want to setup an home network with a wireless router and use multiple switches for wired connections through out my home. I currently have an Airport extreme hooked up to a cable modem and a leviton gateway hooked up to the Airport. The 2 computers connected to the Leviton are on a windows 7 homegroup and share fine, but won't share or discover any wireless device connected to Airport. My main goal is to have a wireless/wired network with all computers sharing information with each other. I want 2-3 wired switches/gateways with a min of 2 devices connected to each, connected to my wireless router whiich is connected to cable modem.

the problem is that for no apparent reason at no apparent interval the net on my laptop will go to just a local only connection. when i tell vista to repair it, it says either dns problem or connectivity issue, the way i get past it is to disable the wireless connection then re-enable it. i think my laptop is the only machine effected.

I have a WRP400 VOIP Cisco router.... The WRP400 seems to hamper my ability to access outside the network over time. If the router is plugged in for an amount of time, my broadband (35mb UPC) gradually tapers down to nothing. As soon as I restart the router, my broadband access shoots back up to the full 35mb.I've been on to UPC numerous times, they say their connection is stable & good..... must be router.I have a DVR (security camera system) that when plugged into the WRP400, seems to exacerbate the issue. It normally takes the router two few days to hamper internet access.when I plug-in the DVR internet access goes from 35mbps to 0.5mbps in a few hours. I've update the Firmware to the latest Version: 2.00.26.
