Customs alerts when a port-channel is down.
Hi,
I want to receive syslog alerts when a port-channel is down, or when a interface from the port-channel is down or if is possible to know when a neighbors is unreacheable or lost.
Is possible?? I have tried to configure Automated Actions in the tool syslogs on RME (LMS 3.2) when a interface is down (LINK-*-3-UPDOWN:* LINK-*-5-CHANGED:* LINK-*-5-UPDOWN:*), but I received alerts messages from others interfaces when only I want the interfaces that form the port-channels.
Thanks,

Well if it's the only remaining channel link, the port-channel goes down. If not the only remaining channel link, the port-channel continues without it. As you note, you lose bandwidth and I believe traffic will be rehashed across the remaining channel links, which can result in less optimal load distribution.
Protocols like STP or a routing protocol shouldn't see a link outage or flap.

Alert when Sender Communication channel is inactive/down
Hi,
Kindly let me know if we can generate an alert using alert configurations/rules when Sender Communication channel is inactive/down.
Thanks.
Regards,
Aditya.May be in the channel monitoring the channel is stopped. If you are sure that the channel is active in ID and in Start mode in communication channel, then it is a cache issue. Then, perform full CPACache refresh.

SAN Switch 9148 UPG procedure when using Port Channel
Hi,
I am kind of new to the UPG procedure of Cisco Switch, and the customer i am working with is using Port Channel.
Do i have to shutdown the port channel before executing the switch UPG or if everything can stay up? Will i lose connection when the UPG will proceed ?
If anyone has some documentation that describe the process, it would be much appreciated.
Thank you

Raising alert when JMS Messaging Bridge goes down
Hi
I am using Oracle FMW 11g and have implemented Messaging Bridge. Things are working fine now.
My requirement is whenever the Messaging Brdige goes down or goes into Inactive state, i wanted an alert / notification to be generated so that some action can be taken
Can some one send me the related inputs to implement the same
Thanks
vamsiHi Inaki,
Thank you for the note. but this feature is available from 7.3 SP13 but we are on 7.3 SP4.and it is very difficult to upgrade to SP13.
For us the webmethods will place the messages in their queue and PI pick those messages using the Sender JMS channel with following configuration,
transport protocol:Access JMS provider Generically
Message protocol:JMS1.X
Is there any other solution to trigger an alert when the thread is hung? Also is it possible to auto referesh a channel?

Wlc 5508 get error when use port-channel
We have two wlc in the system 5508 and 4402.
we config HA for 2 wlc, both wlc enable LAG
When I connect 2 interface of 5508 to 2 interface (in a port channel mode on, trunk, dot1q) of a
couple of VSS switch, I cant management 5508 through web any more, and I still can do with 4402.
If I shutdown 1 port int the port-channel, it work well.
Do you know what happen ?
Thanks
Duyenhi Scott,
We have VSS ( 2 x 6509) trunk with (2 switch 4506). one port of wlc4402 connect to one port of one swith 4506.
2 ports of wlc 5508 conect to 6509, each port connect to one switch 6509.
the config in VSS switch like this:

Raising an Alert ,when the Legacy system is down
Hi,
I want to raise an Alert or some thing when my Source Legacy system is down.
My scenario is File -to - IDOC . I'm getting all the XML files from the FTP server. so, My source system is FTP srever . Due to network problem or some other problem my FTP server is getting down very frequently. Now i want to send this information to respected persons in a automated way.
Is there any option that know the Legacy server status , How can we know that FTP server is down .
Please suggest me some solution for this type of prblems.
Regards
JainHi
You can use BPM and check whether the system is up or nt (using the Connection FM STFC_CONNECTION )
In case of system errors and application errors you can use alerts.
System error: Runtime errors, mapping errors , application system is down, Adapter engine is down etc....
application error: If you are checking some validations , if they fails you can throw alerts.
For application errors you use BPM.
You can raise alerts if mapping, receiver determination etc.. fails in the integartion engine. You need to configure alert rules for this. You can go to RWB->Alert Configuration->Where did the error occur? choose integration engine and you can see different error categories and error codes which can be configured using alert rules. Refer this michal's weblog for configuring the same..
/people/michal.krawczyk2/blog/2005/09/09/xi-alerts--step-by-step
Currently alerts for Adapter framework errors are not supported.
You can also raise an alerts from BPM for any mapping failures, send step system errors/application errors using fault messages (through exception branch).
Refer this weblog for configuring an alert in the BPM
/people/michal.krawczyk2/blog/2005/03/13/alerts-with-variables-from-the-messages-payload-xi--updated
hope this helps..

Customized massage when OBIEE (OPMN) services are down.
Hi,
We have OBIEE 11g installed on Weblogic 10.3.3.0 and we have to have an outage message when either BI presentation Service or BI server goes down.
Basically redirection to different URL or customized HTML page.
I believe there is a customization which possible in weblogic.
Can anyone direct me to it?
Thanks!Neal,
This is a great question and it can be handled in a few different ways.
1.) You could modify the web.xml configuration file of the analytics web appliction for OBIEE. the web.xml file is located in teh /web/ folder for the main OracleBIServer. Remember, the analytics application (OBIEE Presentation Services) is just a Java application running in a container, so you can modify the deploy descriptor file to react to a 400 or 500 error. You get the 500 error when the Presentation Services component of OBIEE in OPMN is down. Here is a link on what you need to do for the web.xml file after you locate it (restart the BI Server and components afterwards. you may even need to redeploy the /analytics web application as well)
Re: Customise Error pages in Weblogic
2.) You could create a script that runs on the server at a short interval to run the opmnctl.bat|sh command and call the specific component to seek the single status of the presentation services comopnent. Parse the status and if it returs "Active" then all is good, if else, use your scripting skills to send a notification via email, etc.
A combination of the two might be plausible as well, I'm not sure of the full requirements you have.
Please mark this response as helpful or the right answer - Sunday is points awareness day. : )

I have 2 dlsw router at head quater office, named dlswA and dlswB.
From branches router, dlswA is a primary peer and dlswB is a backup peer.
Both dlswA and B have 2 fast ethernet interfaces.
The current configuration of dlswA and dlswB are 1 port as IP port and other port as sna/bridge port.
With this configuration the problem is when SNA port at dlswA problem, then dlsw circuit will have the problem, because dlsw peer from branches still connected to dlswA.
if I configure 2 fast ethernet port become a port channel. And configure IP and bridge group at port channel interface (IP and SNA at the same interfaces), so when the port channel is down, then branches will connect to dlswB as a backup peer
Are the port channel configuration will solve the problem ? How about the stability of this configuration?Thank Matthias for your reply.
Both of head end routers are on the same vlan and the host is using same mac address.
As far as i know if from branch have 2 active peer with cost setup, there will loops posibility because both head end routers are using ethernet with same vlan and same host mac address.
I test the port channel within my LAB using netbios, seem works as expected. when single port at port channel down, branch circuit still remain at dlswA router, when all port channel member down, the branch peering move to dlswB.
Here are the config:
hostname dlswA
dlsw local-peer peer-id 192.168.255.1 promiscuous
dlsw bridge-group 1
interface Port-channel10
ip address 192.168.255.1 255.255.255.248
bridge-group 1
interface FastEthernet0/0
no ip address
duplex auto
speed auto
channel-group 10
interface FastEthernet0/1
no ip address
duplex auto
speed auto
channel-group 10
end
hostname dlswB
dlsw local-peer peer-id 192.168.255.10 promiscuous
dlsw bridge-group 1
interface Port-channel11
ip address 192.168.255.10 255.255.255.248
bridge-group 1
interface FastEthernet0/0
no ip address
duplex auto
speed auto
channel-group 11
interface FastEthernet0/1
no ip address
duplex auto
speed auto
channel-group 11
end
Hostname Branch
dlsw local-peer peer-id 172.16.0.1
dlsw remote-peer 0 tcp 192.168.255.1
dlsw remote-peer 0 tcp 192.168.255.10 backup-peer 192.168.255.1 linger 0
dlsw bridge-group 1
interface Loopback0
ip address 172.16.0.1 255.255.255.255
interface FastEthernet0/1
no ip address
duplex auto
speed auto
bridge-group 1
But I'm not sure this scenario will work for sna application like ATM machine, and SNA SAA gateway.
Please kindly advised, Is there any alternatif ? -
Total speed for port-channel when config speed 1000 in nexus5548?
hi ,everyone.
now i connect cisco 6509 and nexus 5548up using two 1000M link,and i want to binding two link as port-channel,
because 5548up port is 10GE ,cisco 6509 port is 1GE,i config speed 1000 in the nexus5548 ethernet port ,and i find
that speed 1000 commade auto config in interface port-channel,so i want to know the total speed in this port-channel
is 1000M or 2000M when the port-channel speed config as 1000?i appreciate for your help!!
the topology like this:
1000M
6509 port-channel speed 1000M nexus5548UP
1000Mhi again
The speed of the links and portchannel is 1000M but the bandwith of the portchannel is 2000M -
ACE - Port-channel High Availability
We have configured two ACEs with high Availability. ACEs link with our cores, switches cat6500, through a port-channel, ACE’s ports G1/1 and G1/2. High availability works fine if some vlan down but it doesn’t work if an interface down, only if both interfaces get down because then, all vlans of the channel port get down two.
If possible get an interface port-channel high availability?
Thanks for your help in advance.Thanks for your answer. I have two Cat6500, no VSS possibility. I have two ACEs so each one has configured a port-channel with one Cat6500 (two ports). It works fine. Any problem with that. My issue is when one port-channel of both port is down, failover doesn’t works then, only if both ports are down or vlans are down. I think high availability is only possible in vlan interfaces, not in physical interfaces.

Requirement for Alert when outbound idocs are failing
SAP A -
IDOCS -
> SAP B
We currently have a SAP A system sending outbound idocs to SAP B system via ALE. The current issue is when SAP B system is down. The outbound idocs being sent from SAP A system fail.
We want to get a alert when the System B is down.
What are the options available in SAP to achieve this requirement.
Thanks in advance for any inputs that will be provided.
Regards,
Chandra KumarDear Chandra,
The logical solution to the problem is as below,
You need to have a Function module which checks the RFC connections between two systems before sending idoc. If the connection is found OK then the idoc should be send else a Alert message should be raised u201CSystem B is down, idoc can not be processedu201D
Please let me know if this solution helped in resolving your query.
