Dear sir :

There are some problem when I config static arp table

in Switch3750 ? Following is description :

Section 1 : If static arp command already config on Switch3750 , then the PC connect to Switch3750 . PC's performance is very bad . Include Ping / FTP .

At this moment , MUST config " No arp ...." , then re-type static arp command " arp .... " , after that ,the problem will resolved .

Section 2 : Same as Section 1,static arp command already config on switch3750 ,and PC already connnect

to switch3750 . When PC disconnect the link almost 30 second then PC re-connect to switch3750. After that the PC's performance like Section 1 ,need to remove arp command the add again ,then the problem will resolved .

Section 3 : Same as Section 1 , Static arp command already config on switch3750 , nd PC already connnect

to switch3750 .When Switch Power off / power on , The PC's performance just like Section1 and Section2 .MUST remove static arp command the add again ...

It may be a bug and you can check with bug tool kit in cisco.com. This bug was resolved in the latest IOS version. Check with configuration with example scenario in Cisco and also check the maximum number of arp entries in the device, it may also cause the device.
