SSH login failing though management vlan access

Need some help with getting a 3750e switch, that was on a different network to this new network.

This 3750e is working in production but I am not able to access this switch remotely ssh.

I have added the management vlan and ip address to this switch, I have change the default-gateway address to new network. 

I am able to ping default-gateway, i am able to open a ssh connection to default-gateway, can login to default-gateway.

I was am able to do the same thing from default-gateway to new switch

Using this command ssh -l (username) (IP address)


Any ideas or commands that can help me thank you 

There is no logging turn on really so help on know which logging to on would be helpfully as well.

Did you mean to write that

Did you mean to write that you are "able to do the same thing" or "UNable..."?

I don't quite understand the question if you didn't mean that.

If you can't log into the switch using ssh can you share your configuration - at least the "line vty" section?

Also, verify the presence of an RSA key on the switch - use the command "show crypto key mypubkey rsa".

I corrected my sentence,

I corrected my sentence, thank you for that

I have pasted the line vty config

line vty 0 4
 session-timeout 5  output
 exec-timeout 5 0
 logging synchronous level 3
 transport preferred none

here is the aaa 

aaa new-model
aaa authentication login default local
aaa authorization exec default local
aaa authorization network default local
aaa session-id common

I have verify that a RSA is generated 

% Key pair was generated at: 18:06:20 CST Feb 28 1993
Key name: TP-self-signed-3930785152
 Storage Device: private-config
 Usage: General Purpose Key
 Key is not exportable.
