SSHv2 allows data to be exchanged via TCP and it builds up a secure channel over TCP.
Besides, SSHv2 supports other service ports besides standard port 22, thus to avoid illegal
attack from network.
Before accessing the A10E/A28E via SSHv2, you must log in to the A10E/A28E through
Console interface and starts up SSHv2 service.
The default configuration to accessing the A10E/A28E through SSHv2 is as follows.
