I have 4 6509-E switches all the same configuration/hardware/revision/IOS levels. 1 switch fails (all WS-X6748-GE-TX) when "switchport host" command is enters on an interface range. Although a "show run" shows that all interfaces have portfast configured. What is causing this CLI output? don't know if the switch ports work, the switches are not yet deployed.
switchport mode will be set to access
spanning-tree portfast will be enabled
channel group will be disabled
"portfast" failed for Gi3/1
"portfast" failed for Gi3/2
"portfast" failed for Gi3/3 etc.
