Logging event link-status

Is this enabled by default on Cisco IOS switch ports? What logging level will ensure I see link status in the router buffer log?

logging event link-status global (global configuration)
To change the default switch-wide global link-status event messaging settings, use the
logging event link-status global command. Use the no form of this command to disable the link-status event messaging.
logging event link-status global
no logging event link-status global
Syntax Description
This command has no arguments or keywords.
Defaults
The global link-status messaging is disabled.
Command Modes
Global configuration
Command History
Release Modification
12.2(25)SG
Support for this command was introduced on the Catalyst 4500 series switch.
Usage Guidelines
If link-status logging event is not configured at the interface level, this global link-status setting takes effect for each interface.
Examples
This example shows how to globally enable link status message on each interface:
Switch# config terminal
Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)# logging event link-status global
Switch(config)# end
Switch#
Related Commands
logging event link-status global (global configuration)
logging event link-status (interface configuration)
To enable the link-status event messaging on an interface, use the logging event link-status command. Use the no form of this command to disable link-status event messaging. Use the
logging event link-status use-global command to apply the global link-status setting.
logging event link-status
no logging event link-status
logging event link-status use-global

No logging event link-status on SG300

How can I do it (no logging event link-status) on Cisco Small Business 300 Series Managed Switches (SG300)?

no logging event link-status
This command disables the logs generated when port(s) go down or up.

Logging event trunk-status vs link-status vs bundle-status

Hi
This is not really a query regarding the above interface level commands, but just looking for someone elses view on the differences regardless of however subtle they are.
No links please, like I said I know what they are and do.
Just your real life expereinces why you needed bundle-status for instance will do just fine.
thanks in advance

Three different use cases for status notifications.
I'll give you my experience with using these commands and where they are useful.
Logging event trunk-status--this command is particularly useful for tracking security vulnerabilities as well as trunk mismatches when you're relying on DTP for trunk negotiation.
Say you have a trunk uplink on a switch that links to a distribution switch. This trunk carries traffic for multiple VLANs (thus the very definition of a trunk).
Lets say the other side of the link on the distribution switch is for some reason changed from a trunking state (switchport mode trunk, or switchport mode dynamic desirable/auto) to a non-trunking state (switchport mode access). If the uplink on your access layer switch is not hard-coded for trunk-mode (switchport mode trunk and/or switchport nonegotiate), then your uplink interface can potentially be changed from a trunk port to an access port and only carry traffic for a single VLAN. This would leave other clients on the access switch VLANs stranded from the rest of the network. This logging mechanism would let you know that the switchport is no longer an operational trunk, even though the link status would still be up.
Of course, as a best practice, you should never rely on DTP to form trunk links, especially on uplinks.
The second use is for security--if you have an interface that you KNOW should never become a trunk interface (i.e. an access port where clients connect), and for whatever reason the interface becomes a trunk link (due to a compromised switch or an over-reliance on DTP), you could potentially expose VLANs that users should never have access to. This logging mechanism would let you know if that happens.
Logging event link-status--this one is simple--it logs whether the interface is up/down or changes. One thing I find this useful for is on particularly important interfaces--uplink interfaces, routing adjacency interfaces, server interfaces, etc. Use this on any port when you want to absolutely know if it goes down.
Logging event bundle-status--this one is fairly simple as well--it logs whether there is a change in the port-channel. This could be triggered by a member interface leaving or joining. One reason you would want to use this is for guaranteed bandwidth and configuration consistency.
Sometimes port-channel members leave a channel-group because the configuration is changed on one member and not on the other, likely by mistake. This could catch an error like that and cue you on where to look into the issue. As for bandwidth, obviously you don't want to believe you have 20Gbps or 2Gbps on your uplink, then find out that you actually have half (or whatever portion) of that bandwidth missing because a member has left the port-channel. Both situations can be avoided by monitoring the status of your bundle (or port-channel).

Link status messages in syslog

We have configured all of our switches to send their syslogs to our What's Up! Gold syslog server. Unfortunately, the logs are getting swamped by tons of link-status up/down messages almost all of which are from a bunch of Alertus beacons that cycle their interface every 18 seconds.
No logging event link-status will work globally on my 4500 switches but the command is strangely only interface level on smaller form factors such as 3560, 3750 and 3850 24 and 48 port switches. I want to use prime to create a template but with different port configurations in most every location I'm looking at a full day connecting to each switch individually instead of 5 minutes using a Prime template.
Is there any newer versions of IOS for the smaller switches that makes this command global?

You can use the range command:
interface range gigabitEthernet 0/1 - 16

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!

Event Log Help Links No Longer Working?

Have the help links in the Windows XP event log entries been discontinued?
They used to open up the Help and Support Center with further information about the Event Log error if it was available.
For some time now they have all just given a "page not found" error, which then re-directs to Bing with offered results that are no use at all!
This happens now on every XP system I've tried it on.
As a user of Windows 8.1 as well as XP, I'm well aware that the Windows 8 Event Log help links have never worked so far, but the XP ones always did, and despite the looming "End of Support" I can see no reason for all that information to have been
removed.
Any explanation for this?
Thanks, Dave Hawley.

Hi - thank you DaveHawley for the report. Just wanted to confirm that I've passed this on to the team that looks after the redirect service behind the "More Info" link.
There have been some major changes in how this redirection works over the years as well as in the last months. The most recent efforts added the option to enable use of the TechNet Wiki [sample]
to allow the community to comment & contribute for a given component. I'm only guessing here, but this might have accidentally impacted XP.
Thanks

Prime Infrastructure 2.0 Link Status Alarms

Hi,
we are used SNMP traps sent from our core switches to our PI 1.3 server to notify us about link down events. In this scenario we got emails only for link down events on our core switches.
Now, we are using PI 2.0. It seems PI 2.0 checks link status of all devices on its own. We got an email for a link down event on any of our switches. To avoid that I configured PI 2.0 to treat Link down events as Informational instead of Critical (Administration > System Settings > Severity Configuration, Link down). Now, we don't get email notification for link down events at all.
Is there a way to configure PI 2.0 to inform us on link down events on our core switches, but not on a link down event on any of our other devices?
Timo

Disable the trap from the configuration on the switches you don't want to get messages from. So depending on what kind of switch it would be something like:
conf t
no snmp-server enable traps linkdown linkup
Your string may different, there are several options that can be included in this line. You may have to remove the whole line and readd it with only the options you want.

Missing boot events on the Diagnostic performance operational log (event-id 100)

I noticed that event (100) is not always reported or not reported at all on several machines and I would like to understand how can I force reporting it.
In addition I would appreciate if you can explain regarding the keys under:
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Diagnostics\Performance\Boot]
Things I've already tested on win7:
1. Verified that the diagnostic performance > operational log is enabled
2. Services: ‘Diagnostic Policy Service’ (auto) and ‘Diagnostic service host’ (manual) were running
3. Verified that GPO is not disabled for:
- Computer Configuration\Administrative Templates\System\Troubleshooting
- Diagnostics\Windows Boot Performance Diagnostics Computer Configuration\Administrative Templates\System\Troubleshooting and Diagnostics\Diagnostics: Configuration scenario executing level
Thanks,

For keys under [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Diagnostics\Performance\Boot]
Please take a look of discussions in this link(reply posted by David J)
Diagnostics-Performance log Event 100 - Critical, Error, or Warning - when and why?
http://social.technet.microsoft.com/Forums/windows/en-US/48005f5d-5f66-439a-af51-3a2ebb894e31/diagnosticsperformance-log-event-100-critical-error-or-warning-when-and-why?forum=w7itproperf
My understanding to this issue—“event (100) is not always reported or not reported at all on several machines”
is that : this kind event log occurs when an time parameter during the boot process reaches a threshold in the registry key, then a warning, critical or error message will appear in the event viewer. If it doesn’t reach the threshold, then there will be
no report.

REST API event-source-status pagesize

Hi,
I'm having an issue with the REST API method event-source-status
I want to get the method to return a list of all the attached event
sources. I have about 1400 attached to Sentinel but on calling the
method only 400 entries are returned.
On my test env (I have 4 event sources) I have tried to modify my script
to call event-source-status?pagesize=1 with the intention to read 1
object, then effectively going to the next. However the results via
postman appear to show that with a pagesize of 1 that 4 items are
returned with 1 next link, and on pressing next the same 4 items are
returned.
All I want to do is iterate through all event sources but dont seem to
be able to get them all in 1 list or get them in the pagesize I
require.
Any help welcome.

Hi,
If you would like to iterate through all the event sources in a
paginated manner, use this URL:
1. To get all the event sources attached:
/SentinelRESTServices/objects/eventsource
2. To get N-number(Say 5) event sources / per page:
/SentinelRESTServices/objects/eventsource?page=1&pagesize=5 (This comes
with next url which would look like, <next
xlink:href="https://164.99.175.172:8443/SentinelRESTServices/objects/eventsource?page=2&pagesize=5"/>).
In above example, the 'page' attribute is for the page number you are
querying for.
and the 'pagesize' is the number of elements you would like to retrieve
in the page you mentioned by 'page' attribute.
You should be able to crawl through event sources with the next and prev
url.
I have tested it with Sentinel 7.2 and found working as expected.
In your query above, you have mentioned about
/SentinelRESTServices/objects/event-source-status url.
To get all the event sources' status just call
/SentinelRESTServices/objects/event-source-status (without any page
attribute).
Let us know if both the REST EP(/objects/eventsource and
/objects/event-source-status) works for you as expected.
In your query

CCP 9.4 - Service Link Status

Hello there,
I recently configured CCP 9.4 on our lab.
I was able to connect to CCP portal successfully with domain name and checked the Service Link status was green, but when i change the domain name to WORKGROUP after that i didn't get the Service Link status green and it was red.
So, i checked on log file and i also saw error message on running Jboss server regarding to unable to connect with this error :
" Unable to connect to 'http://abc.xyz.com:8080/Integration
ver/ISAdminServlet?action=iseeConnectionStatus&ObjectInstId=0': java.net.UnknownHostException: abc.xyz.com01519689514078465::***Error::CommunicationsBase: Unable to connect to 'http://abc.xyz.com:8080/Integration
ver/ISAdminServlet?action=iseeConnectionStatus&ObjectInstId=0': java.net.UnknownHostException: abc.xyz.com "
here, abc=my hostname , xyz.com=domain name
so, to change this "abc.xyz.com" to "abc" because now my server was under WORKGROUP, what file i need to edit. So, i will get green status of Service Link.
I also attach the images of the error.
I appreciate you direction.

Recon Event Deferred Status

Hi,
When a new user data is sent from peoplesoft (Trusted source) with future start date, workforce sync message is in not process until start date, leaving it in "Event Deferred" Status.
I have experienced that with SAP connector we can disable the feature to wait till start date for Recon event to be processed and Link the event which creates user with status "Disabled until start date".
Is there a similar solution with PeopleSoft ER connector? I have tried to find it in Connector documentation but could not find it.
Please help me find the solution for this.
Thanks in Advance.

Hi,
To process future dated events which are in 'Event Deferred' status you need to write custom scheduled task.
Search for reconciliation event with 'Event Deferred' status and iterate through Result set and get Reconciliation event key and future date (Reconciliation Manager.Future Date)
then check number of days difference between current date and recon future date and as per your business requirement you can process the recon event.
to process future dated recon event you need to set status to 'Event Received' because with status "Event Deferred" OIM does not process them.
HashMap<String,String> updateMap = new HashMap<String,String>();
updateMap.put("Reconciliation Manager.Status", "Event Received");
//update Recon Event data
reconUtility.updateReconEvent(reconEventKey, updateMap);
//then process reconciliation event - reapply matching rules
reconUtility.processReconciliationEvent(reconEventKey);
Try this. It will work. Let me know if you need more information
Thanks,

How to change URL for "Log Out" link in CE?

We need the Communications Express "Log Out" link to go to a different page to the usual log in page. How can I change this?
I've found the logout function in the uwc/common/Header.jsp file which looks like:
function logout() {

top.window.location = url;
}and I've found the getLogoutURL fuction in the uwc/js/resourceBundleUtils.js file which looks like:
public String getLogoutURL(HttpServletRequest request)
    return UWCApplicationHelper.getLogoutURL(request);
}But I can't find where the URL is actually configured.
any help would be much appreciated.

You got it in one. If you wanted the logout button to redirect to google you would set:
function logout() {
   url = "http://google.com/";
   top.window.location = url;Then restart the web-container.
and I've found the getLogoutURL fuction in the uwc/js/resourceBundleUtils.js file which looks like:
public String getLogoutURL(HttpServletRequest request)
return UWCApplicationHelper.getLogoutURL(request);
}But I can't find where the URL is actually configured.UWCApplicationHelper is in inbuilt java class. The UWCApplicationHelper.getLogoutURL java function returns:
<current URL context>/base/UWCMain?op=logoutSo for example if UWC is deployed to http://myserver.domain.com/uwc you would get a logout URL of:
http://myserver.domain.com/uwc/base/UWCMain?op=logoutRegards,

How Can I Create an Event Link to a Page Tab?

I have a portlet in one tab that generates an event. I want to be able to send this event to the same page but to another tab where another portlet resides. Here's the code snippet that creates the link. This code is part of a custom JSP tag.
// Attempt to get access to the portlet render request to determine if we are within a portal context.
PortletRenderRequest prr = (PortletRenderRequest) pageContext.getRequest().getAttribute(
    HttpCommonConstants.PORTLET_RENDER_REQUEST);
if (null != prr)
    try
        // Set up the parameters used for the link.
        NameValue[] eventParameters =
            new NameValue("linkUrl", linkUrlParamValue)
        // Construct the link parameter we will be using.
        linkUrl = EventUtils.constructEventLink(prr, "linkClicked", eventParameters, true, true);
    catch (PortletException e)
        // Error processing removed...
}This code will generate the event correctly and all processing occurs as expected. However, I cannot find a way to force the second tab to display.
I am able to force the the second tab to be displayed if I use "Direct Access URLs". These links are in the form
[protocol]://[host]:[port]/pls/portal/url/page/[page_group_root_page_name]/[tab_name]
But is there a way to create an event link using a specific URL?

Hi,
One workaround that i can think of is:
1. Set the <passAllUrlParams>true</passAllUrlParams> attribute in your provider.xml of the portlet on the target page/tab.(dont forget to refresh the provider)
2. If you already have the url to the tab, then you just simply construct the form in your previous portlet to post to that url with all the necessary form fields.
3. Process the request parameters and render the second portlet.
hope that helps.
thanks,
Harsha

I need to start and stop logging based on a digital input event(or analog if necessary), log data for several seconds prior to the event, and have the data file close at the end of event and increment the filename for the next logging event.

I don't know if this can be done with VI Logger or need to use Labview V7.1.

After browsing through the VI Logger User Manual, it looks like the triggering that you are hoping to accomplish is possible. However, incrementing the filename for the next logging event is not going to be possible. VI Logger does exactly what its name tells - logs data. I don't think the automation that you are hoping to accomplish is possible.
For help with setting up your application, if you do choose to stay with VI Logger, make sure to chek out the Getting Started with VI Logger Manual.
Best of luck.

How do I create event links in the FPM Application Editor?

I'm am attempting to add a new step to the roadmap of ESS/BEN Benefits Application. I've created a new VAC component and a corresponding view (using the "self-service administrator" role).
When using the FPM Application Editor to create a new perspective, I need to add an event link but receive the error, "Either the perspective "Smoker Verify" has no view assigned to it or none of the view(s) assigned have any event assigned to them".
How do I assign events to my new view? Please assist and thanks in advance.
-Jeff Karls-

I see that the events are defined on the views themselves in the portal content.
