Cisco WAN :: 7200 Link Failure Detection
Nov 28, 2012
Primary optical link between CPE and PE, and backup 3G/ADSL link between CPE and PE.I am considering link failure detection on primary link (after which backup link should take over). Which method is the least CPU intesive:
1) BGP protocol between CPE and PE
2) RIP protocol between CPE and PE
3) BFD on static routes on PE
Is there difference in terms of CPU load between above mentioned methods or they are more or less the same?Hardver platforms are sup720 BXL and Cisco 7200 G2.

I have been having no luck with DLink support getting an answer. I have the DCS-942L which allows me to set the date/time zone but when I try to add motion detection settings the page always times out during the save. I tried using CaT-5 CABLE instead of wifi for settings (camera on same router and desktop pc) but after the "saving" message appears, it eventually times out and I have to click the Back arrow to return only to find none of my settings saved. I also want to note that each time I log in I see a broken certificate error message. Using Win8 with IE10. Also tried on Win7 with IE9 and XP Pro with IE8.

I've just successfully set up my network camera and as I was running through the advanced settings, what it wants from me when it comes to setting up images being sent to my e-mail. I've looked up some old threads to get a clue and thus far nothing works. Testing my entries results in "Invalid e-mail setting" 10 out of 10 times.
The setting format I'm trying to use is as follows:
-- smtp.gmail.com
-- 587
-- myemail@gmail.com
-- myemail@gmail.com
-- myemail
-- mypassword
-- STARTTLS
My GMail account is POP Enabled (whatever that is) and I used the username for that e-mail for bother the Sender and Receiver fields, as well as that e-mails username and password.
I'm lost. I bought the camera so I could document my landlord's maintenance people "touring" my apartment while I'm at work, but I wasn't aware having it save screenshots would be so complicated.

First of all, I've purchased a couple of Wifi cameras in the past, and they've always been missing something important (i.e. just returned a Cisco camera because it didn't support WPA2-AES).
So I was thrilled when I first received the DCS-930L - it was sleek, wireless setup was easy, and mydlink.com is slick as well.
But I'm afraid I've found the fatal flaw. I purchased this camera for one reason only - to figure out how mice are getting into my basement! I set up the camera where I suspect they're coming in, set up motion detection (via ftp), and then walked in front of the camera to test it.
To my surprise, I checked the FTP folder and found dozens of STILL images! What I really need is a video file. Is there NO way to configure the camera to capture video (not still images) when motion is detected? This seems like a huge gap. The Cisco camera I returned could do this.
If it can't do this, can it can be configured to record the last X hours to a shared drive somewhere, so I can at least go back and look at recorded video?

1. To monitor motion in a block you hash it.
2. To monitor motion in a block you leave it clear.

I have a 932L already and wanted to add another camera, so I purchased the 942L in the US. I live in Canada. The 932 works perfectly, emailing me without any problem. Set up was a breeze. This new camera appears to be a problem. I cannot get this turkey to email. I am very computer literate, and I have been working on this thing for ages now without success. I would like to return this thing and get another 932, but hard to do from here. I see from these forums that nobody else appears to have gotten it to work either. By the way, I upgraded it to the latest version firmware, no change. How to email images using the motion detection?

I have been testing my new DCS-942L and found that while the motion detection works great it is sometime hindered by the audio mic setting of motion detection. I have turned down the microphone settings to the lowest (10) and the only difference is miniscule. The camera will still set off the motion detection prior to anyone being in the screen, and if the person enters the screen immediately after the noise the camera will not record the movement.
I have adjusted the sensitivity down to 25% and continued having the issue. I would like to record motion with sound. So either the microphone needs to be able to be adjusted lower, or not set off the motion detector.

I am using my new DCS-930L to monitor motion at a door entrance. It is firing off when motion happens but the image it emails is taken @ 12 seconds after the motion. So the result is I know motion happened but the person who came to the door is long gone or through the door by the time the image snapshot is taken. I get multiple emails containing images of the empty entrance. Is this a software, hardware, firmware or user error issue?

I realize that this is a new product, but nevertheless I have some feedback after running my 4 new DCS-930L camera over the past few days.
Currently, you can configure the camera to EMAIL/FTP images on a schedule or when motion is detected, but not both.
Why does it matter? Because I get flooded with email alerts after I get home from work and later in the evening every time I walk by one of the cameras or whenever a light switch is turned on/off.
If I could configured the motion detection to only alert during a specified schedule of days and hours, it would be great!

I recently set up two cameras. I had set up one for motion detection and email to a gmail account. It seemed to work fine, but then for some reason the motion detection tab didn't show the room like it did before. It doesn't show any picture or anything like it did before, so I couldn't choose the squares to choose the detection area. This is through mydlink account->camera info->advanced settings, and logging in to the camera remotely.So I switched to the other camera, and got it working as of last week. But now, the motion detection doesn't work anymore? It appears to be related to the username/password for the email account. I can no longer send test emails, it says invalid username/password, though the exact same values worked last week, and I didn't change anything. I tried resetting it, then setting it again, but no luck.

I am planning to provide a redudnt link to our customer. The setup as below:
One link over wireless while the other link over wired link, I want to make sure that I should maintain the same public IP addresses for the customer therefore, I am looking for L2 failover for my customer.
If the wireless down the customer should migrated to wired and vis versa. I have 7200 CISCO Router as Core.

The idea is to get the date/time logged motion detection is triggered on a certain time frame of the day (5:00 am to 5:30 am), to a txt file or something like that. I plan to port the log to a html/php website.

I'm puzzled that you don't seem to be able to do this (a basic feature). Seems like when motion is detected you can only send an email or do the DI/DO thing.
I can do this quite well via the direct web-based interface (1.03 and earlier at least) on the DCS-1130, but the 932L doesn't have video record on motion option (baffled as to why not there too, but that's another issue). So, I was thinking of using the DCS software to get motion-detected recording out of the 932L, but looks like I can't do that either?

Motion detection is setup - and I can see in the log and on the Live Video "Motion Trigger Indicator" that this part is working. I can also send test-emails, so the smtp is set up correct. In the Event Setup I have a valid server and a motion triggered event with the status ON. But no emails are sent . In the log there is also no indication of the server trying. Am I missing something - or is this not working for anybody?
And - there is no firmware beyond 1.0 for this model as far as I can see.
P.S. I am using a Gmail account for smtp, port 587 and using startTLS to send with,

I bought a new DIR-615 and tried to install dd-wrt on it. During the installation all of a sudden the router stopped blinking the led lights and stopped responding to anything. It's current status is that I can only see globe LED and the other 4 LAN LEDs in continuous green and NOT blinking. The power LED and wireless LED are not even displaying. I tried all kinds of reset like soft,hard and crash but no response. It's not responding to anything except those 5 LED lights.

I have implemented in my company network recommended by cisco scheme with MEC etherchannel from some segment distribution layer (VSS) to core switches (legacy 650x) exactly as on picture: Core switches have rather old IOS (Version 12.2(33)SRB4 and i have reasons not to upgrade it now) which dont support many functions - like BFD over Etherchannels and Enhanced PAgP. And we run a OSPF/MP-BGP/MPLS bunch over those links with OSPF reference bandwidth configured to such values that failure of one link in etherchannel will not lead to link cost changes (we dont have a lot of traffic for now on those links and 1 link can handle it easily) and consequently will not trigger changes to RIB and BGP topology table.
Problem is that i am afraid that in case of one of link of portchannel will fail (but without port down event - unidirectional link or smth else) it will take rather long time to converge - and im talking about L2, not L3 protocols. Cos i cant implement BFD and ePaGP over this link - best i can do that improve 30 seconds PAgP hello timer to 1 second. But at least 3 seconds of possible traffic blackholed - is rather big problem.First time i considered 2 possible solutions:
1) BFD - but even i can use it, it will not improve much recovery time cos 750 ms for BFD over etherchannel not much better that 1 second PaGP fast timer.
2) ePAgP - as i understand this protocol have enhancements to discover failed link faster and improve recovery time, but all information i can find about it - is how to use it for dual active detection and none about timers improvements. So i cant be sure that i should upgrade IOS on Core switches and it will improve my failure detection time. ( if it possible adduce some links to description of this protocol enhancements in comparison with PAGP)
For now im already thinking about using four L3 links (instead of 2 portchannels) and BFD over those links with 50 ms hello timer. But in case of link failure reconvergence of OSPF will take some time, and BGP will react to this no immediately, so i am afraid that even using aggressive timers for routing processes and hellos i will not win much time.

We have FEX (2232TM) connected with 2 x NEXUS N5K-C5596UP.
One port Ethernet 101/1/7 which was connected to Dell Server went down...
It was working for a couple of weeks at least. Then the link went down and now I'm unable to get anything connected to this port As I said, this already happened before, but unfortunately I can't remember if it was on the same port/fex ... from the fex uptime it seems that this was on another fex I was able to get the link back up by doing a power cycle of the fex
At the moment Dell server is connected to different port Ethernet101/1/4.. See config bellow:
. config, how ports are configured
interface Ethernet101/1/7
description VM008 Network 1
switchport mode trunk

I'm only able to restore my settings from a backup taken in July 2011. Any backups that I take, say today for example, won't restore. Any attempts to restore them is returned with "The restored configuration file has been uploaded in failure." I haven't changed my router. The firmware remains the same. I'm using Firefox, though I believe I've always used Firefox to interface with the router.

I have a 5508 controller with 70 AP's ( a mix of 1131 and 1142). On the Monitor tab I can see under the Rogue Summary numerous "Rogue AP's" as well as the clients associated to these AP's. There are no Rogue AP's on my wired network according to the report. My question is this: What actions should I take regarding these "Roague AP's"? Many of them appear to be just other AP's in the residential area near by. I know I can take action to classify them as Friendly or Malicious as well as Internal or External, but what benefit is there to doing this? Will taking these actions keep my AP's from scanning off channel for Rogues? I read that if a "Rogue AP" is not on the wired network that is really is not considered a threat. Any Cisco best practices regarding how to handle detected Rogue AP's ?

I have a simple question regarding dead peer detection on the ASA 5520. I am using a cellular VPN device to connect back to an ASA 5520 and I have noticed that the connection drops at random periods during the day. The vendor for the cellular device recommends disabling dead peer detection on their device, which I have done. The question is, where is this disabled on the ASA? is it the IKE Keepalive setting under the tunnel group option?

I'm running a 5505 with DHCP on the outside interface. All 5505 are connecting to 5545.Can I configure the ASA for a site to site to automactically discover the the peer address and automatically establish a connection with 5545?In other words can I configure all settings for the site to site except the peer address. Once connected on network and get outside DHCP, can it also put that address is the peer section of site to site?

I am interested in gathering cumulative threat-detection statistics from an ASA running 8.3, and displaying number of attacks over time. I am already capturing traffic information via netflow, but am interested in getting threat information.
Is there a way to capture the statistics via SNMP or any other method?

I have a Cisco 2801, IOS 12.4(24)T2 (C2801-IPBASEK9-M) on a WAN link to another 2801, which appears to be wrongly detecting our cross-site EMC replication traffic as Skype.
I am 100% sure that Skype isn't running on any of our PC's, yet the Skype protocol is by far the highest used out of everything. I have watched these traffic stats late at night when nobody is on the network and when the only traffic is replication, and this is the protocol which is constantly increasing.
If I run 'sh ip nbar port' , Skype isn't listed in the port-map. If I use ? at the end of the command, it lists Skype as option. The 'sh ip nbar protocol-discovery' show the following (among others):
FastEthernet0/1/0
Last clearing of "show ip nbar protocol-discovery" counters 6d10h
Input Output ----- ------ Protocol Packet Count Packet Count Byte Count Byte Count 5min Bit Rate (bps) 5min Bit Rate (bps) 5min Max Bit Rate (bps) 5min Max Bit Rate (bps) ------------------------ ------------------------ ------------------------ skype 76133998 146572068 6167477623 173614718864 0 0 1221000 8973000
EMC have informed me that the port used for replication is 8888, but I can't see how NBAR can think this is Skype.
why NBAR is detecting Skype traffic?!

It is possible to detect situation when two neigbour routers involved in EIGRP routing are configured by mistake with different AS number ?I tried this situation practically. Two routers are connected together via Serial link network. One router has AS 1, other AS 10. I try to detect AS mismatch. First I check what EIGRP packet are comming debug ip packet detail show source <my neighbour IP address> destination 224.0.0.10 Ip protocol type 88. These packets are EIGRP Hello packet.
I try to go more deeply into details.debug eigrp packetsI see only ongoing EIGRP Hello packets. But I don't see any incoming packet from my neighbour (which has different AS number). It seems, because of different AS number router silently drop eigrp packet.Other debug eigrp command also doesn't show any info about AS difference.

I just switched schools and I work for HP's marketing team part time which entitles me to get on some websites blocked by our school's network (sonicwall block).I then tried a proxy on Firefox and it was blocked as the sonicwall detected that I was using a proxy. Why did this happen and is there a way to bypass?This is mainly on wired connection as the Ethernet isn't god awfully slow like wireless is.

I'll cut right to the chase: I've been having some serious problems with wifi detection. There are times when the wifi is detected successfully, but most days, my laptop can't seem to detect any. The wifi light goes on and off as well. Also, there are times when the wifi suddenly just goes off and fails to detect any, even after it has already started working.Usually, I have to turn off my laptop and wait for it to cool before the wifi starts working again. I already have that power save mode option unchecked, so I don't really know what's causing the problem.
