Cisco WAN :: LMS 4.2.3 Is Not Generating Protocol Flap / Down Alarms?
Apr 10, 2013
We are using CISCO LMS 4.2.3 in our network in India, we are facing a issue regarding alarm generation for a protocol flap/down, especially when BGP / OSPF neighbourship got flapped.These flapping will result in the data service degradation , by which we came to know that some protocol flap may occurred at router end & then we go for the manual check by login into the router.After escalating the same to cisco we came to know that it is a bug of Cisco LMS. using any other method/technique to view the protocol down alarms automatically for cisco routers.

I am having an issue at one of our remote agencies whereas we are getting numerous mac-flap notifications on our switches. This has become kind of a hinderance as we are getting tired of seeing these messages. The end users havent been complaining.
It's usually occurring with the same mac-addresses over and over. Upon further investigation, we found the mac-addresses are all on laptops which have both wireless and wired nic's. There are wireless AP's (cisco 1242's) in use which they can connect. We also found where the error is popping up as they move from wireless into docking into their docking station which has a lan cable attached. I was under the assumption that the wireless mac and wired mac were different numbers and therefore if the wired was up simultaneously with the wired, as it switched over, they shouldn't get a flap.

Does Cisco WLC 5508 runnig code 6.0.196.0 allows you to generate CSR? Or do you have to use OPENSSL like in previous versions?

I currently have a stack of 3750G switches with a cross stack etherchannel connected to a 3750E stack in the distribution layer.The 3750G stack is running 15.0-2SE IP Base. I began noticing the Mac flap issue when I was Re-enabling dot1x on the switchports. As first I thought dot1x maybe have contributed to this so I removed it from the stack temporarily.I am still seeing Mac flap logs usually when a machine reboots or re-connects back to the network. These are all wired desktops.I started looking at the etherchannel configuration which is using LACP. The 3750E stack looks fine with all ports in mode active. On the problematic 3750G stack I noticed 3 of the ports in the etherchannel set to mode active and 1 port set to mode passive. The port shows as bundled but I can't imagine this is ok.The only other difference on this one port is there is no mls qos commands like on the other 3 interfaces in the port channel.I mainly need to know what the Mac flapping is about. Whether it is a bug or related to the current etherchannel configuration.

I've got a a customer that is using a single sign on product that uses agents installed on the customer's domain controllers. This works fine accept for one scenario. When the customer transitions from a wired to wireless connection or vice versa. We have determined the reason for this is that the DCs are not getting Windows logon events ie 540 on 2003 servers or 4624 on 2008+. The users have files shares mapped onto member servers but refreshing those is not hitting the DCs.
Any way to ensure hitting a domain resource generates a logon event on a DC without directly mapping a resource on a DC. If it matters there are 50 domain controllers and around 200 member servers spread all over 48 states.

We are currently implementing the new Prime LMS (4.1), and we met some strange problems with the «Alarms» (footer/bottom right).Under implementation we had a bunch of false positive alerts, so we went in and ticked of all of them to choose «Own it» and «Clear».Something happened and the browser crashed, and when opening the browser again and browsing to the “Fault monitor” from “Alarms” could we see that all the alarms was cleared from the view, but LMS was still telling us that there is two alarms (down in the footer/bottom right).
When going into the “Fault monitor” from clicking on “Alarms” we got the “spinning wheel of death”.The browser crashes after a while and we have to log in again.Now, when we have some alarms after rebooting the WLC’s, we get the 6 alarms from interfaces down, but the two remaining alarms it’s talking about is nowhere to be found.
Future more, the browser crashes yet again after a while and we have to log in again.If we are doing other tasks, and keeping away from the “Fault monitor” everything is working fine.The browser crash/lms hang occurs only when accessing the “Fault monitor” section.
We have looked everywhere for what is causing this. Something with the two alarms that’s lost in the system keeps the browser/lms to crash. But damned if I can find where to get rid of them / clear them.

This coming from multiple servers, but mostly its generated by the most utilized ACS server.At this time, we are running ACS 5.3.0.40.6
No impact just annoying alarms. How to stop these alarms ?
Am using OOB modems on network resource routers used as aaa clients.Nothing connected to ACS console ports.Only 8 character usernames with AD.
I do see a few software defect / enhancements for ACS ver 5.3. When they will be fixed / enhanced?

We have a couple of IBM blade chassis with Nexus 4000I 10G blade switch in it. Four 10G ports from each Nexus 4000I switch are bundled into a port channel and connected to Nexus 7K. On the 4k end, one port in the port channel is doing down and coming up as an idividual port. After few minutes it is going down again and coming up as a port-channel member port. It is happening quite offen. [code]

Here is an example of what each switch logs when a server drops offline. Sample logs taken between 5:32am and 5:35am on Feb 20. This particular one was having problems all weekend. Switch #1 encountered over 2000 interface resets. The corresponding VPC port on Switch #2 only had 13 resets.

I have setup a new Prime server 1.2 and am monitoring routers and switches from it. It shows me the device status and all as expected. now when i manually turn off the connectivity of one switch, i do see the alarm generated by the Prime but it doesnt send the email notification.
i checked my mail server settings and have right details of the mail server and email address of the recipient. Also when i run test on that page, i can see the test email coming through.

Upgraded LMS to 4.1. Yep basically reinstalled. However I can't remember how I did a couple of thing on the original system.
I am trying to take the traps from the Cisco equipment to the LMS and generate e-mail. How do I take the incoming traps (Crit and Warning) and send an e-mail alarm. I'll plan to control what to trap on at the Cisco Equipment.
SNMP trap is set from a fan fault, the Cisco send a trap to the LMS. Now I want take that trap and forward via an email.
I have been reading the admin documentation on "Notification and Action Setting". I see how to take the Cisco LMS created trap and email alarm. (In this case I need a specific trap that LMS did not have.) I see how to take Cisco Traps and resend them to other NMS.

Recently I had came across 1 issue where one of the server IP had conflicted with VIP of Nexus core switch. The blade server was physically connected to Nexus Distribution switch which in turn connects to Nexus core. Neither Nexus core nor distribution had generate any logs in regards to IP conflict which ideally happens on Cisco catalyst switches. I haven't find any document on cisco as well as on internet for this issue . I dont know what logging need to enable on Nexus for this specific case . There are different logging levels define for every feature like hsrp, ip,monitor etc...

Everytime the console port is plugged in, the alarm contacts (1-4) randomly assert (trigger) and then clear themselves in random orders. Nothing is plugged into the ALARM port and all Alarm setting are default. Below is the syslog message and Alarm Settings:

Region : UnitedKingdom
Model : TD-W8951ND
Hardware Version : V5
Firmware Version : 22.05.2012
ISP :
I have a TD-W8951ND v5 on the latest firmware.
I recently broke my broadband data cap which surprised me as I had not been using the internet much.
I only have tablet which I switched off having first checked the router to make sure there were no other wireless connections and adding MAC address filtering to be sure no one else was stealing my bandwidth. With just my router connected to the ISP, my ISP has recorded 170MB of downloaded data in 3.5 hours. Switching off the router stops the traffic being recorded (as you would expect), but when switched back on the large data transfers start up again.
I have plugged in an older router (not wireless) and no traffic is generated, so it seems to be the TP-Link router rather than my ISP or ADSL circuit that is at fault.

I was working on a problem the other day and came across something that I had seen before but never given much thought. I had a router with a switch connected to it and the interface was showing as Ethernet0 is up, line protocol is down. The problem in the end turned out to be a cable that had fell out because it was not connected correctly, but I was able to replicate this interface status on a router (FastEthernet0/0 is up, line protocol is down), and NO cable was attached to the interface.I've had a look on the internet but cant seem to find a good answer, so does anybody else know why this status is shown on the router? Remember, NO cable is connected to the interface so it isn't a speed or duplex problem

I'm looking to make a possible configuration for a customer. They need a device to provide :- firewalling- bandwidth limiting based on protocols, IP, users- web content filtering- good reporting to see which device/users are consuming most of the bandwidth.I used to use cisco ASA as firewall but it's a while I last installed on and I'm nt uptodate which current state.So I thought of using an ASA 5512-X but I'd like to know if it comply with all the requirements .Most important being the reporting and bandwidth limiting capability. It would be great to have some configuration example regarding bandwidth management.
