Multiple port configuration on Cisco 2950

Hello,

I can’t configure multiple ports at a time, while can configure single port.

LonMAP2950#conf t
Enter configuration commands, one per line. End with CNTL/Z.
LonMAP2950(config)#int range f0/2-5
^
% Invalid input detected at ‘^’ marker.

LonMAP2950(config)#int f0/2
LonMAP2950(config-if)#

Your help appreciated.
