Smart Call Home on Nexus

[jmandersson]

Hi Experts!

I can't get Callhome to work on our Nexus switches. We use a Transport Gateway with e-mail between devices and the gateway.

The problem is that the Nexus won't send any email, though it always default to the CiscoTAC-1 profile for which I have not specified an e-mail address. On my custom destination-profile there of course are a e-mail address specified but it's never used.

Here my config:

callhome

  email-contact xxx@xx.xx

  phone-contact +xxxxx

  streetaddress xxxxx

  destination-profile XXX-XXX

  destination-profile XXX-XXXformat XML

  destination-profile XXX-XXX message-level 4

  destination-profile XXX-XXX email-addr xxx@xx.xx

  destination-profile XXX-XXX alert-group Diagnostic

  destination-profile XXX-XXX alert-group configuration

  destination-profile XXX-XXX alert-group environmental

  transport email smtp-server xx.xx.xx.xx port 25 use-vrf default

  transport email from xxx@xx.xx

  enable

When i try to register by using callhome send diagnostic this is what shows up in the debug:

2012 Apr 18 14:35:42.949270 callhome: Destination profile CiscoTAC-1

First, the version helps identify if you are hitting a bug. To get the entire call home configuration, use the command show run callhome all.

Now on to your specific issue. Check the output to

show callhome destination-profile

There is an issue in Nexus 7000 when you upgrade, the email configuration shows in the running configuration but not in the destination profile. But it is an old bug. You can check if your email server shows up there in the command output.

But the answer might be easier than that. Some user generated Call Home messages are sent at severity level 2. Since you have

destination-profile XXX-XXX message-level 4

in the configuration, these severity 2 messages will *NOT* be sent - only messages above severity 4 will ever be sent.

Please try again after configuring the following command

destination-profile XXX-XXX message-level 0

In case you are wondering, Call Home severities are opposite of syslog severities. Here is the mapping

Call Home Level	Keyword	Syslog   Level	Description
9	catastrophic	N/A	Network-wide catastrophic failure
8	disaster	N/A	Significant network impact
7	fatal	Emergency   (0)	System is unusable
6	critical	Alert             (1)	Critical conditions, immediate attention needed
5	major	Critical         (2)	Major conditions
4	minor	Error             (3)	Minor conditions
3	warning	Warning       (4)	Warning conditions
2	notification	Notice          (5)	Basic notification and informational messages. Possibly independently insignificant.
1	normal	Information (6)	Normal event signifying return to normal state.
0	debugging	Debug          (7)	Debugging messages.

The last suggestion if that does not, is look at the quickstart configuration guide for what you are doing and then fallback to opening a TAC case to do some 1-on-1 debugging.

I noticed I did a typo when I wrote "only messages above severity 4 will ever be sent". I meant to say that only messages at severity 4 or above will ever be sent.

BTW, callhome send diagnostic is a severity 2 message.

Hi Lawrence!

We are using 5.1(3)N1(1A)

Yes, the destination-profile XXX-XXX message-level 4 seems to be the problem, great.

Another thing a noticed that looks suspicious is that some configururation lines seems to get duplicated.

  transport email smtp-server 10.10.10.24 port 25 use-vrf default

  transport email from callhome@xx.xx

  transport email smtp-server 10.10.10.24 port 25 use-vrf default

  transport email from callhome@xx.xx

If I remove one of the lines, the other one also disapears. Everything works, so I guess it´s cosmetic.

Thank you

Johan
