  • 1.  Filter trap MM-MC

    Posted Jan 20, 2023 06:15 AM
    Hi,
    I tried to filter snmp trap on my airwave as I saw a lot of snmp trap from AP which is not interesting for me for example :
    wlsxUserEntryAttributesChanged
    wlsxUserEntryCreated
    wlsxUserEntryDeleted

    even if I have disable this trap on the MM at the /mm hierarchy :
    (SRV-Mobility-Master) *[mm] #show snmp trap-list | include wlsxUser
    wlsxUserAuthenticationFailed Yes Disabled
    wlsxUserEntryAttributesChanged Yes Disabled
    wlsxUserEntryAuthenticated Yes Disabled
    wlsxUserEntryChanged Yes Disabled
    wlsxUserEntryCreated Yes Disabled
    wlsxUserEntryDeAuthenticated Yes Disabled
    wlsxUserEntryDeleted Yes Disabled

    I saw these traps on the airwave comming from AP ..... what's the problem ? How can I filter these traps which take a huge number ?

    thks for your help.

    Those traps need to be disabled/enabled in the MD hierarchy, because they are sourced by the MDs.  The MMs also send their own traps, but not the traps you are observing.

    Hi,
    thks for your reply but it's really clear for me.
    One the MC, I see :
    (CTRL-Wifi1) *#show snmp trap-list | include wlsxUser
    wlsxUserAuthenticationFailed Yes Disabled
    wlsxUserEntryAttributesChanged Yes Enabled
    wlsxUserEntryAuthenticated Yes Disabled
    wlsxUserEntryChanged Yes Disabled
    wlsxUserEntryCreated Yes Disabled
    wlsxUserEntryDeAuthenticated Yes Disabled
    wlsxUserEntryDeleted Yes Disabled
    (CTRL-Wifi1) *#
    (CTRL-Wifi1) *#
    (CTRL-Wifi1) *#configure t
    This controller is managed by a Mobility Master.
    Configuration changes can only be performed on the Mobility Master.
    (CTRL-Wifi1) *#

    and on the MM at the /md hierarchy :
    (SRV-Mobility-Master) *[md] #show runn | include wlsxUser
    Building Configuration...
    snmp-server trap disable wlsxUserAuthenticationFailed
    snmp-server trap disable wlsxUserEntryAttributesChanged
    snmp-server trap disable wlsxUserEntryAuthenticated
    snmp-server trap disable wlsxUserEntryChanged
    snmp-server trap disable wlsxUserEntryCreated
    snmp-server trap disable wlsxUserEntryDeAuthenticated
    snmp-server trap disable wlsxUserEntryDeleted

    and the command to view trap configuration result of going to /MM ..
    (SRV-Mobility-Master) *[md] #show snmp trap-list | include wlsxUser
    The commands for applications run on MM need to be executed on /mm tree.
    The commands for applications run on individual devices need to be executed on the device node in 'mdconnect' mode.

    On the /MM :
    (SRV-Mobility-Master) *[mm] #show running-config | include wlsxUser
    Building Configuration...
    snmp-server trap disable wlsxUserAuthenticationFailed
    snmp-server trap disable wlsxUserEntryAttributesChanged
    snmp-server trap disable wlsxUserEntryAuthenticated
    snmp-server trap disable wlsxUserEntryChanged
    snmp-server trap disable wlsxUserEntryCreated
    snmp-server trap disable wlsxUserEntryDeAuthenticated
    snmp-server trap disable wlsxUserEntryDeleted
    (SRV-Mobility-Master) *[mm] #
    (SRV-Mobility-Master) *[mm] #show snmp trap-list | include wlsxUser
    wlsxUserAuthenticationFailed Yes Disabled
    wlsxUserEntryAttributesChanged Yes Disabled
    wlsxUserEntryAuthenticated Yes Disabled
    wlsxUserEntryChanged Yes Disabled
    wlsxUserEntryCreated Yes Disabled
    wlsxUserEntryDeAuthenticated Yes Disabled
    wlsxUserEntryDeleted Yes Disabled
    (SRV-Mobility-Master) *[mm] #

    Is there something I miss ? does I need to restart a process ?
    Why the configuration are not synchronised between the MCs ans the MM ?

    You would make changes in the hierarchy by doing cd /MD, config t and make your changes and write mem to push the changes.  To see the result, you could either cd <hostname of md> and then mdc or SSH into the MD individually to see the trap list.

    Hi,
    It's works now :-)
    I don't know what really was wrong (I was sure regarding the write mem ).
    Anyway thanks for your help and that confirm the synchronisation process between the MM and the MCs.
    Now the MCs are less "noisy" regarding snmp trap.

    Have a good day.
    Brgds.
