Is AES-256 the same as Rijndael 256 ?

[hessie]

Topic says it all, would like to connect to a cisco box which only allows AES-256

Yes, it is. Or pretty much.
From the Wikipedia article: http://en.wikipedia.org/wiki/Rijndael
Strictly speaking, AES is not precisely Rijndael (although in practice they are used interchangeably) as Rijndael supports a larger range of block and key sizes; AES has a fixed block size of 128 bits and a key size of 128, 192, or 256 bits, whereas Rijndael can be specified with key and block sizes in any multiple of 32 bits, with a minimum of 128 bits and a maximum of 256 bits.
