    Hi,

     

    I have a 2xEX2300-48p virtual-chassi that sends these syslog messages 24/7 (around 128K per day):

    How do I stop these messages from being generated? And if I can't and there's nothing to worry about, how do I stop them from being sent to my syslog server?

     

    thanks in advance

     

    best regards,

    Peter

    These are non-impacting logs, Do you see any impact due to these logs?

    you can suppress them using below kb if you wish.

    Hi,

     

    I don't see any impact at all. I have now exluded the log messages from local messages and being sent to my syslog server.

    Thank you so much for answering my questions and making me aware of Problem report search 🙂

     

    Best regards,

    Peter

    I'm having this same issue. I already added something to filter them out from the switch logs when I look at them locally, but for some reason I still get thousands of them in my syslog server. 

     

    Do I need to do something different to filter them from syslog? 

     

    Thank you

    When you filter messages in syslog you need the match conditions to appear under BOTH the file stanza and the syslog server stanza for it to affect both.

     

    In other words the match condition limits only apply to the specific section of logging where they appear in the stanza.

    Thanks guys,

     

    Below is what I have in the config to filter this message and a few others I was getting, it seems to work for my other juniper switches, only one of the stacks is filling my syslog with that error.

     

    set system syslog file messages match "! (ifd null) | (pfe_bcm_l2_mac_delete|pfe_bcm_l2_mac_add) | (.*loadDefaultService:: supported on tomca t only.*)"

    set system syslog file messages match "! (ifd null) | (pfe_bcm_l2_mac_delete|pfe_bcm_l2_mac_add) | (.*loadDefaultService:: supported on tomca t only.*)"

    This stanza is not sending any syslog to an external server as it is not configured only the local file.

     

    There will be an additional section with server and the ip address for those forwarding syslog.  In those cases you need to include this same match condition under the server section in addition to the one under file.
