Hello
You are probably not in the global configuration context. You need to enter configure terminal or shortened config before you can change any config settings.
Here is what happens when I enter directly int 34 speed-duplex
HP-2530-48#
HP-2530-48# int 45 speed-duplex
Invalid input: int
Here I first enter conf, the promt changes and after that I can enter interface 45 speed-duplex. You can see all the options for your reference
HP-2530-48# conf
HP-2530-48(config)# int 45 speed-duplex ?

I think auto-10-10 is also not a valid option. You need to determine if the end device supports autenogotiation or only fixed settings, if it supports full or only half duplex.
