Hi All, Uploading IOS 15.2.SE7 to a number of 3750 switches using tftp. This proved very slow, so I decided to use SCP which was a lot quicker. However, SCP caused a cpu spike on the switch which caused snmp drops. Has anyone ever experience this?, the switch was passing data traffic normally. Rgds Harry Harry Hambi BEng(Hons) MIET Rsgb
