SNMP Trap and logical hostname

Consider a case in which a cluster node has two public network interface in a IPMP group and a logical hostname (ip addr) is also assigned to one of the interfaces.
If an SNMP trap is generated from this cluster node, what would be the source IP address in the IP header of the trap?
Is there a way to restrict the source IP addr to one of the interfaces?

There is only IPMP group so I'm not sure what you mean by active/standby groups. If your question meant to ask whether the interfaces within the group are in active/standby, the answer is no.
Even if they were active/standby and the trap always travels over the active interface, the question still remains whether the source IP address would be the physical address or the logical address, assuming the logical address is also assigned to the same interface.

Looking at the error message "The Network Adapter could not establish the connection" , It appears hostname and port may be incorrect. Review the targets.xml under E:\oracle\product\10.2.0\db_1\SAP_solman_SDB\emd and
emoms.properties under E:\oracle\product\10.2.0\db_1\SAP_solman_SDB\config folder to make sure host ( sap_solman) and port (1527) are correct.
As far as setting the environment variables goes, you can go to control panel -> system -> advanced -> environment variables and set the ORACLE_HOME and ORACLE_SID

I don't see any snmp message in debug output ..
am i missing something or it is not possible to get traps directly from ip sla .. do i need EEM for this?

sorry, it actually worked .. i just gave a restart to ip sla and it worked.
looks like router was already in threshold stage when i was activating reaction-config ..
but i am still confused which command is actualluy generating these traps since i have taken out some of the snmp config out and i stil get traps ..

SNMP Traps and DCNM 6.1(2)

Hello Everyone,
I have DCNM 6.1(2) installed on a Windows Server 2008 R2 to monitor and manage 4 Nexus 7018 (12VDC's).
I currently have one problem left. All snmp traps send from the Nexus Switches are all dropped and none processed, and i currently rely on the syslog messages, but would prefer the snmp traps.
I start wondering if the snmp traps are only for SAN devices?
Or If I am doing something totally wrong. Port for the traps is 2162. Discovery via snmpv3 works... Traps are sent and recieved but dropped.
Perhaps someone could shed some light into this.
Thanks
Pol

Hi,
Yes, DCNM for SAN supports forwarding of alerts using Cisco Call Home, EMC Call Home, email, and Simple Network Management Protocol (SNMP) traps.
DCNM LAN supprts Syslog and E-Mail.

Difference betwn shared address and logical hostname

Hello,
For cluster 3.2, could someone explain the diff betwn "clreslogicalhostname create" and "clressharedaddress create"? I thought the former was to share a logical hostname (depending on DNS to resolve to the ip address) betwn nodes, and the latter to share ip address (don't need to rely ip address resolution). But examples of the latter use a hostname and not an ip address, which leads to my confusion.
Thank you for clarifying this!

You've got things a little bit confused.
A logical hostname resource is an IP address (and associated hostname) that is placed in a fail-over resource group and used by the application(s) in that resource group. Such a resource group is resident on one node only and thus the IP address only exists, i.e. is plumbed in, on that cluster node too.
An example of such a service would be, say, an NFS service, with the IP address being the one you mount shares from. Alternatively, it could be an HA-Oracle database with the IP address being that of the listener that clients connect to.
A shared address resource is an IP address (and associated hostname) that is placed in a fail-over resource group but is used by applications in a scalable resource group. The shared address IP/hostname becomes a global IP address, such that it is physically plumbed in, e.g. on bge0:1, on the cluster node where the fail-over resource group is mastered and also plumbed in on the loopback interface, e.g. lo:2, of the cluster nodes that run the scalable services that depend on it.
An example of such a service would be a scalable web server, e.g. Apache or Sun Java Web Server, that is run on multiple cluster nodes at once and has requests load-balanced to them directly by the cluster. The scalable IP address would provide a single address that clients could use, yet the requests can be serviced by one of several nodes.
Hope that helps,
Tim

SNMP Traps and Monitoring UCS

Hi Guys;
During the implementation of UCS Blades I found a number of issues that have not been solved. I need to monitor the UCS solution through a NMS with traps and monitoring certain items. To do this I require deliver the MIBS to the Monitoring group and tell the OIDs to monitor certain things but I dont found especific documentation about this. I need to monitor things like the states of the fans, cpu, memory and connections.
The solution consists of:
Fabric Interconnects: 2 x 6140XP
Chassis: 9 x 5108
Servers: 70 x B230M2
UCSM v1.4
Although i need apply certain security to SNMP like ACL to secure the solution in the Customer Environment.

One IP Address to create a IPMP and logical hostname?

Hi,
Is this possible to have a network failover in sun cluster with one IP address ( requirement is in two node cluster, each system having one NIC port. IPMP group will have only one IP address which is also use as logical address also)?
Thanks

Hmmmmm?!?
I doubt it. In your cluster setup, one of the nodes would always have no(!) IP address. Actually, before you would configure your logical IP address, none of your cluster nodes would have a valid IP address, as the logicalhostname resource would want to plumb the address.
Re-reading your post, the answer is no. This setup will have all sorts of problems.
Regards
Hartmut

Snmp trap and WLSE

hallo
in a wireless network with WDS service and WLSE, all Infrastructure APs are registered to WDS. To manage alarms, faults etc in Infrastructure APs the logs must be sent to the WDS or directly to WLSE ?

You have to send the logs to WLSE.

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.

TimesTen SNMP traps

Hello,
I have TT over Windows 32 bit (stand alone).
I'm trying to configure SNMP traps in order to maintain Alerts for the TimesTen database.
I've followed the doc *"Oracle Times Ten In-Memory Database Error Messages and SNMP Traps"*,
and comfigured the snmp.ini file.
However, when I'm trying to use the utility snmptrapd.exe in order to start listening to the snmp traps and doing my tests, I'm getting an error: snmptrapd.exe is not a valid Win32 application, and in the CMD window I also see *"Access is denied"* error.
My user in the Administrators group.
Why do I receive the error and how can I overcome it ?
Thanks in advance,
Roni.

Hi Roni,
Getting this executable working independently of TimesTen is the first thing to look at.
- Where did you get the snmptrapd.exe executable from?
- Make sure that you get this executable from a known reputable source.
There are viruses out there that use this name.
- The MKS version of this utility is supported on Windows 2000, Windows XP, Windows Server 2003 and Vista.
- Make sure that you have the correct version of the executable for your Windows platform.

EBGP PEER FLAP SNMP TRAP

Hi
Whenever there is a bgp neighbour flap, we are not getting snmp traps on the HP NNMI Server.. I believe during the neighbour flap, the device is unable to communicate with NNMI and drop the trap..
So I would like to write a custom EEM SCRIPT that can match a syslog pattern and generate a customised SNMP trap and send it to NNMI. May be I can delay the trap generation or sending so that the device restores the connectivity and then send an alert
Here are my questions:
Is this a good idea?
Can you give me a sample configuration with the MIB Values to be generated?
What MIB Should be loaded on the server?
I am curious how others are monitoring this kind of bgp flaps...

Groupwise SNMP TRAPS To Omnibus

Hello,
We are currently using Groupwise 7 however I am not the administrator.
I am more in charge of monitoring. We are looking to monitor Groupwise for issues and I have been looking to see if and how Groupwise can send SNMP TRAPS. I can not seem to find any information on this and when I called Novell they seemed lost.
Could anyone tell me....
Is Groupwise able to send SNMP TRAPs and if so where is this configured?
Thank you in advance for any help.

Did you look at the MIBs included? I haven't for a long many years.
I think they are mostly get/setters not traps though

Does it cause more CPU utilization? Do i need to enable snmp traps to monitor network using solarwinds NPM. I have configured community string and snmpserver host address.
Thanks
Vipin

Hi Vipin,
We usually configure SNMP traps to monitor our network reachability and availability. If anything goes on Device whether it is a link down situation or any issue with protocol running on the Device. So, whenever anything goes wrong on the device it generates an SNMP Trap and notify you if you have configure SNMP-Server host to receive the notifications/traps.
To configure SNMP host command following is the command that you need to configure:
(config)#snmp-server host
E.g.:
snmp-server enable traps snmp authentication linkdown linkup coldstart warmstart
Above trap will send you send you following information :
>Authentication : if any one tries to poll the device using wrong community string
>linkdown/linkup : if any of the interface/ports/links goes down it will notify you
snmp-server enable traps bgp
Above trap will send you traps regarding problems with BGP running on your Device
Now I come to CPU part, yes it may spike CPU sometime if regular polling is done from the Management Server or if any MIB has long output. You can use Solarwinds NPM for the same however if it causes high cpu then you have to openup a TAC Case with NMS team to have the issue resolved.
To know more about MIB's on your device you can execute command on your Device 'show snmp mib' and can translate the MIB's using following link to know more about particular MIB :
http://tools.cisco.com/Support/SNMP/do/BrowseOID.do?local=en&translate=Translate&objectInput=1.3.6.1.2.1.15
