I have a 3750 running 12.2(35)SE5, and everyime I run the 'interface range' command, my telnet session freezes, but then resumes after a minute or so.
I thought that the CPU may be getting pegged, but its not. I opened a separate telnet session to the same device and a 'sh proc cpu' showed barely 11% utilization.
So why does the switch take such a long time to bring me back to the command prompt? Is that simply the time it takes to execute command?
switch (config-range)#switchport mode access vlan 333
(I press enter, and the it stays like this for a minute or so) then....
