Hi , Please help me to know whether the IOS " c2801-adventerprisek9-mz.124-15.T17.bin" will support the below commands.

1) ip ssh server algorithm encryption aes256-ctr

2.)ip ssh server algorithm mac hmac-sha1

Sorry but the 2801 is end of sales for almost 2 years now.

One disavantage of using obsolete equipment is that you will not be able to take advantage of newer features. You would have to upgrade to a current router to use the newer software with the feature you are asking about.

No it will not. Those commands require a minimum IOS version of 15.5(2)S or 15.5(2)T.

That requirement is documented in the following references:
