    Intel Modular Server System MFSYS25 and second Ethernet switch


      Good day, I have opted to install a second Intel Gigabit Ethernet Switch AXXSW1GB in our Intel Modular Server System MFSYS25. The second switch is at present intended to provide additional ports, so it is linked to the primary switch using a patch cable. However I am concerned that this may not be ideal, as I have noticed several event log entries (info only) as follows:


      Type: SNMP
      Detailed Description: Link Down: External: Port 1<br> Array ( [ifIndex.1] => 1 [ifAdminStatus.1] => up [ifOperStatus.1] => down )


      Type: SNMP
      Detailed Description: Link Up: External: Port 1 has link and should now be active <br />        Array       (           [ifIndex.1] => 1           [ifAdminStatus.1] => up           [ifOperStatus.1] => up )


      Detailed Description:
      Spanning Tree Port State Forwarding: {port}<br> Array       (           [rndErrorDesc.0] => %STP-W-PORTSTATUS: Ext.1: STP status Forwarding           [rndErrorSeverity.0] => warning           [rnd.] => 1           [rnd.] => 0       )


      These are associated with "Switch 2", and may reoccur every minute for hours at a time. There do appear to be infrequent brief connectivity issues, but I am uncertain whether they are related to these events.


      I have reviewed the common configurations document (http://www.intel.com/support/motherboards/server/sb/CS-031684.htm) and no mention is made of any special precautions while adding a second switch.


      I would appreciate it if someone could confirm whether simply linking the two switches together is a supported configuration out-of-the-box, and if not, possibly provide a link or guidelines for the proper configuration.


      Thanks in advance.
