Further investigation tells that the uplink of my switch connecting to the FTD produces a lot of NBNS traffic that causes my switches to go 100%.</P><P>Do anybody knows here why is this happening? How to control those NBNS traffic to prevent broadcast flood? Thanks</P> Fri, 21 Feb 2020 17:41:36 GMT fatalXerror 2020-02-21T17:41:36Z https://community.cisco.com/t5/network-security/slow-connection-after-migration/m-p/3958017#M937538 <P>Hi Guys,</P><P>I just migrated to 2100 FTD and we are encountering slow connection issue either in LAN or WLAN.
