Cisco Switch - spanning tree command
I have two of the same switches
Cisco Catalayst 2950
One of them takes the following commands, while the other one doesn't
spanning-tree mode pvst
no spanning-tree optimize bpdu transmission
spanning-tree extend system-id
I get the following error on switch 2, which is supposed to work as the backup for switch1
Switch2(config)#spanning-t ree mode pvst
^
% Invalid input detected at '^' marker.
Please tell me how I can issue the three spanning-tree commands to the second switch.
Thanks,

So, upgrading is the only way out?

thanks guys,
Here is what i did
Step1 - loaded tftp server on my machine
Step2 - copied the flash image of switch1 on tftp server
Step 3 - logged in to switch 2
Step 4 - pulled the flashimage of switch1 from tftp server (Step 2)
now, i want to use the new image (c2950-i6q4l2-mz.121-20.EA 1a.bin) on my switch... how do i do that?
Here is the output of "show flash" command
