Does Goph support SSH connection to Cisco devices?

[ricardo-ml]

If support , how to connect it ?
I tested Cisco devices using the following code:

client, err := goph.NewConn(&goph.Config{
	Addr:     "1.1.1.1",
	User:     "aaa",
	Auth:     goph.Password("123456"),
	Port:     22,
	Callback: ssh.InsecureIgnoreHostKey(),
})
out, err := client.Run("show vlan")
fmt.Println(string(out))

then i got error is: wait: remote command exited without exit status or exit signal
