Link down and Link Up Snmp trap C#

Hi i've configure my cisco router to receive the SNMP traps if the link goes up or down. However i found out that when i plugged out the cable i'm not receiving any link down on the network management system. Until i plugged in again the link will then show up or down state. May i know whats the reason why i can't receive the link down when i plugged out my cable?

If your router has only fa0/0 as active interface, then this would be the interface that the router would use to communicate with the network management system. However when you unplug that interface now the router has no interface that it can use to send the link down trap to the network management system.

Problems with RH 9Printed Documentation not displaying some popups, drop-downs, and links

I generate a Word document for reviewers. PrintedDoc properties include: Retain hyperlinks; Include drop-down text; Include expanding text.
Sometimes the Word 2010 document includes hyperlinks, sometimes it doesn't.
Popups typically don't work in the Word document.
Drop-down and expanding text appear intermittently in the Word document.
Has anyone experienced this and have a solution?
Thanks.
Carol

I have never known hyperlinks to fail except in two situations.
The target topic is not in the printed document. Obviously it cannot link to something that is not there.
The hyperlink is a popup.
Not sure what you mean by popups not working in a printed document. If you mean the links to them break, then see above. Known issue.
I'm not sure why you are having the dropdown and expanding text problem as I have not known that to be an issue either. Is it always the same dropdowns that fail? Have you compared a good dropdown and a bad dropdown?
Take a look at Printed Documentation on my site.

WLSS3.0 and application code SNMP trap error

Hi,
I'm trying to generate SNMP traps through application code as described in the documentation at [url http://e-docs.bea.com/wlcp/wlss30/programming/snmptraps.html]. By using an SNMP manager I have verified that WLSS can send traps during startup and shutdown. My application code, however, fails to do so. When my SIP servlet is deployed, I get the following errors.

Hi,
what you show us is not teh servlet mapping but the servlet definition. The servlet mapping maps a configured servlet to a URL. You can use the property editor in JDeveloper for this. Just select the web.xml file and choose "properties" from teh context menu

Link up and down messages

Hello,
I'm trying to determine the root cause of the following:
Why would I get a "link up" message before I get a "link down" message?
$ grep "link down" messages*
messages:Jul 8 11:03:14 box02a bge: [ID 801593 kern.notice] NOTICE: bge0: link down
messages:Jul 8 11:04:48 box02a bge: [ID 801593 kern.notice] NOTICE: bge0: link down
$ grep "link up" messages*
messages:Jul 8 10:59:57 box02a bge: [ID 801593 kern.notice] NOTICE: bge0: link up 1000Mbps Full-Duplex
messages:Jul 8 11:04:48 box02a bge: [ID 801593 kern.notice] NOTICE: bge0: link up 1000Mbps Full-Duplex
Visually all network cables look secure. The server has not been touched, and no known network issues reported. prtdiag -v does not show any faults either.
Any help is appreciated.
Thanks

the link up messages are time stamped before the link down, so that seems normal. If your interface is "flapping", going up and down, then ensire you are using CAT6 cables and link autonegotiation on the interface AND the switch.

Fibre Link Down

We have been using an Apple RAID with 8 disk (4 in each controller side) for almost 6 months, each controller in the raid is conected to a Qlogic 5600 and from there to 3 IBM servers using slicing and LUN mapping.
Suddenly since two weeks ago we have been receiving this logs AT IRREGULAR intervals:
Upper Controller 04/01/08 08:51:09 PM RAID Controller 1 Fibre Link Up
Warning Upper Controller 04/01/08 08:51:08 PM RAID Controller 1 Fibre LIP
Warning Upper Controller 04/01/08 08:48:48 PM RAID Controller 1 Fibre Link Down
And the windows server report that the SCSI disk have been disconnected, when we stop all the servers and reboot the raidfabricsservers works for 2 to 5 days and again the same messages.
Any idea of what is happenning and how to handle this ?
Humberto

+ the ports on the fibre switch should be configured right for storage/hosts:
RSCN suppression on / device scan off for hosts
and vice versa for storage
+ the logs from the FC are hidden, you can access them following the next procedure. (As explained in the [qlogic event manual|http://www.servants.co.jp/qlogic/pdf/2-259060-00_A-QLogicFCSwitchEventMassageGuideFW40.pdf]
Archiving and Downloading the Event Log
You can use the command line interface to create a file on the switch that contains
the most recent 200 entries plus the previous 1000 entries. This file can then be
downloaded to the workstation using FTP. To create and download a log file, do
the following:
1. Log into the switch through Telnet and create an archive of the event log.
The Set Log Archive command creates a file on the switch named logfile.
QLogic #> admin start
QLogic (admin) #> set log archive
2. Open an FTP session on the switch and login with the account name images
and password images. Transfer the file logfile in binary mode with the Get
command.
ftp ip_address
user:images
password: images
ftp>bin
ftp>get logfile
xxxxx bytes sent in xx secs.
ftp>quit

SNMP trapping PRI channels up/down

Hi guys.
I am re-configuring some routers to generate traps for our new monitoring tool.
I have noticed that after I applied the snmp trap configs that we are getting traps for PRI channels (30 voice channels), which I wouldn´t like to. This happens when users are using the voice channels on demand. When they hang up, the used channel goes down and I get a trap.
Basically, regargint the controller, the only interface that I must monitor is the signaling one (my case is the channel 0/3/0:15) or if the entire controller goes down.
Below, the snmp trap config:
snmp-server ifindex persist
snmp-server trap-source Loopback0
snmp-server enable traps snmp linkdown linkup coldstart warmstart
snmp-server enable traps envmon
snmp-server enable traps isdn layer2
snmp-server enable traps isdn chan-not-avail
snmp-server enable traps isdn ietf
snmp-server enable traps bgp
snmp-server enable traps hsrp
snmp-server enable traps ipsla
snmp-server enable traps voice poor-qov
Could you please help me to figure out how I can solve this?
Also, if you guys have any other advises and more ways to monitor the voice environment.
Thanks in advance

ISR 3945 - SNMP trap set up to recieve option pings from ASR1006

I am working on a set up : ISR 3945 - Receiving option pings from another device (ASR) and sending a snmp trap (say ex: if a link down on a dial-peer ) to snmp server if those option ping fails.
- Need inputs on SNMP config
Thanks in advance.

Hi.
the easiest way is to get the snmp-server trap source command to work.
when you say it's not working, do you mean the branches still use the external interface as the source? or that it's sourced properly from vlan1 but somehow doesn't get encrypted?
what ios version are you running on the branches? maybe this is a bug and newer versions get it to work?
if you want to through another way than snmp-server trap source, then an ipsec redesign might be needed. As you noticed dmvpn would be the easiest. another solution would be dynamic lan-to-lan from branch to headend with gre tunnels (similar to dmvpn), and then force the route to the management network via GRE, this way the snmp trap source would default to use the tunnel ip address.

Fadi.

No SNMP traps from sun x4150 ILOM server

Hi all,
I have set up the ILOM alerts with SNMP traps (v2c,public) according to the ILOM user guide and pressed the "send test alerts". Nothing shows up in the SNMP trap monitor (using MG-SOFT software). When I add another alert of IPMI pet type (same destination ip as of SNMP trap alert) I see events in the trap monitor. It looks like the ILOM does not generate SNMP traps but only IPMI traps.
In the ILOM user guide there is an explicit example of traps sent from the ILOM (in addition to the fact that the ILOM features include SNMP traps AS WELL as IPMI) so it seems this is possible...
my ILOM version is
SP Firmware Version 2.0.2.6
Does anyone have any idea of any step I have missed ?
Thanks in advance.

Once the Network Device (Linux server in this case) is discovered you will still need a rule that targets that class and accepts incoming SNMP Traps for that OID, or All OIDs if you prefer. I found 2 links that may be of help, the first is just a basic
overview of the SNMP listener in SCOM 2012 as it has changed from the OS Listener in 2007 to a dedicated one.
http://systemcentertech.com/2012/05/17/scom-2012-built-in-snmp-trap-listener/
The second link covers SNMP setup, but starting at Step 7 there is a great how-to on creating your own SNMP rule which will be needed to collect your traps.

SNMP traps from EMC SRM to SCOM 2012 R2

Hi,
I'm trying to configure SCOM 2012 R2 as an SNMP trap listner. I've seen many articles on setting this up but all are based around SNMP traps from network devices which must first be discovered and identified in the network device list.
However in my scenario I am trying to monitor/listen for traps send by a Linux box hosting EMC SRM - this management software can be configured to send SNMP traps out so it is these that I need to try and listen for/capture.
So can anyone explain how I can configure SCOM 2012 R2 to do this. I have tried to just used the IP of the Linux box and discover it as a network device but it fails - in Network Devices Pending Mgmt it says No response Ping, even though I can
ping the box from the Server OK - so I am guessing you cant cheat scom in discovering the Linux box as a network device in ths way?
Can anyone offer any advice for setting this up. Just to add I've ensured the RunAs Community String (public) and SNMP version is correct on both side...
Cheers...

CCMS agents, alert monitoring, SNMP traps

Hi Guys,
I have a question. There is a requirement about monitoring. Any documenation or links will be really appreciated.
My client needs me to use CCMS agents, alert monitoring for both ABAP and JAVA stacks, SNMP traps, sending SNMP traps, interface CCMS with third party monitoring tools. Mostly, the ,monitoring is done thru RZ20.
Anybody can point me in right direction or material.
Thanks

Enterprise Manager Grid Control can send SNMP Traps to third-party?

GC 11.1
It looks like a simple config, but I've got into a confusion about it.
I'm trying to figure out the configuration to send SNMP traps to a third party server.
My scenario is:
Node A (managed, monitored) ---- GC box------ SNMP box (final destination).
My understanding is that the traps (notification methods) configured on GC box are generated by the Agent on Node A, then received by the GC and distributed as e-mails.
What is the config to set the traps from A to reach SNMP box?
There is the help page from the GC page (confused about interpretation):
"Add SNMP Trap pageThe Add SNMP Trap page enables you to provide the name of the host (machine) on which the SNMP Master Agent is running and other details so that SNMP traps can be sent through Notification Rules.
An example is shown below.
Name HP OpenView Console
Description Notification method to send trap to HP openview console
SNMP Trap Host Name litleguy.us.oracle.com
SNMP Host Port 162
SNMP Community public
This SNMP host will receive your SNMP traps.
Note: A Test Trap button exists for you to test your setup."
Any suggestions are highly appreciated.
Thx,

Please reply with the specific questions around this.
11.1
EM can send SNMP traps to specific designated receivers. You create an advanced notification method (of type SNMP Trap) with the appropriate details about the receiver.
(See Setup->Notification Methods)
In the notification rules UI, you specify the alerts you are interested in forwarding and select the SNMP trap advanced notification method you created earlier.
The SNMP receiver should be provided the correct MIB that defines the SNMP trap. There were some bugs with the MIB definition in one of the releases (don't recall which one off hand), so if the traps you are receiving don't match what the receiver expects - please let us know and we can point to the right one.

Experiences with sending SNMP-Traps to 3rd party (Nagios)

Hello Colleagues,
i'm working on a project where we would like to monitor our databases additionally sending SNMP-Traps to Nagios.
At the moment i'm using net-snmp-utils and snmptt. The snmptt-traphandler is running in daemon-mode and passes incoming SNMP-Traps to Nagtrap.
Now i want to create passive service checks. For example a passive service check for TBS_Usage for database 'exdb' which returns the values from the incoming SNMP-Trap.
Has anyone experiences by implementing the SNMP Notifications (to Nagios)? Is there an easier way to implement this than using snmptt?
Does anyone know, how the MIB (snmptt.conf) must be configured for the passive service check?
I'm looking forward hearing from you soon!
Best regards,
Sönke

Hi Nikhil!
Basically I am trying to set trap forwarding to a
a NNM on the network from sunMC 3.5 Update 1.
I have followed all the directions in sunMC snmp FAQ
and other threads on this forum but I am not able to
set the trap destinations.<snip>
Other thread having same question is
http://forum.sun.com/thread.jspa?threadID=15625&tstart
=0Have you reviewed the options in the other thread? (i.e. Halcyon SNMP integration or HP integration packages). Both are off-the-shelf and if you can understand SunMC SNMP infrastructure you certainly wouldn't have trouble configuring either. If you've looked at both packages, what parts made you decide not to use them? Note: I work for Halcyon.
Building your own custom integration with direct traps may be difficult: the generic snmp faq doens't have all the info you need to do so (i.e. how to get NNM to go backwards to an Agent to request the details of an event like "Warning /op is 95% full" or "Critical: Power Supply 2 is Offline"). I'm not even sure how I'd go about it, and I've been using SunMC for years :)

Snmp trap versus syslog message

Hi,
Most network devices will send snmp traps and syslog messages to a central server.
For analyzing purpose this server runs software to display the messages or traps.
My question is, what is the difference between syslog messages and snmp traps?
What is best practise?
Thank you very much.
Hansruedi

From the very basic level, traps and syslog differ in the encoding. Syslog messages are typically text messages sent within a UDP packet. There is a bit of binary encoding to indicate the syslog facility and severity. SNMP traps have encoded ASN.1 fields (called variable bindings). These varbinds are not ASCII text like syslog messages. Instead they are encoded object identifiers that can be translated into object names using MIB definitions.
More syslog messages exist than SNMP traps because syslog messages do not have as much governance associated with them. However, we typically recommend that customers enable both as there are some details available in traps that you may not get in syslog messages. Traps can also be processed in a more programmatic fashion because of the documentation that goes into the MIBs that define them.

Disable snmp trap link-status only on access ports?

Hello,
I am searching for a way to disable the snmp trap link-status only on access ports.
The problem is that we have a lot of new devices which have no port scheme, so I can't say that everytime the router uplink on a switch is on port X or Y.
So I have to figure out where my uplinks to routers, accesspoints or other switches are and set all other ports to
no snmp trap link-status
no logging event link-status
spanning-tree portfast
Campus Manager knows the uplinks between the devices, but there is no way to perform such a change, right?
The next problem is, that there is nothing configured on the ports, so I can't search for a string by using compliance check in RME.
Is there any posibility to get the topology informations from CM together with the configuration feature from RME?
Thanks a lot!
Sven

Hello,
thanks for your reply.
I thought of something like you wrote...
There is a best practice report for disabling cdp on access ports.
Creating this report for a switch and click on "fix" the CM will configure the command "no cdp enable" on every access port.
So I will have a difference between uplinks and access ports.
The problem with that solution is, that I can't fix all my switches with one job.
And with >1000 switches it is not really possible to click every device.
Any further advice?
Thanks!
Sven
