9.1.3.2 Remote Console
The Remote Console is the redirected screen, keyboard and mouse of the remote host system. To
use the Remote Console window of your managed host system, the browser must include a Java*
Runtime Environment plug-in. If the browser has no Java support, such as with a small handheld
device, the user can maintain the remote host system using the administration forms displayed by
the browser.
The Remote Console window is a Java Applet that establishes TCP connections to the BMC. The
protocol that is run over these connections is a unique KVM protocol and not HTTP or HTTPS. This
protocol uses ports #7578 for KVM, #5120 for CDROM media redirection, and #5123 for
Floppy/USB media redirection. When encryption is enabled, the protocol uses ports #7582 for KVM,
#5124 for CDROM media redirection, and #5127 for Floppy/USB media redirection. The local
network environment must permit these connections to be made, that is, the firewall and, in case of
a private internal network, the NAT (Network Address Translation) settings have to be configured
accordingly.
9.1.3.3 Performance
The remote display accurately represents the local display. The feature adapts to changes to the
video resolution of the local display and continues to work smoothly when the system transitions
from graphics to text or vice-versa. The responsiveness may be slightly delayed depending on the
bandwidth and latency of the network.
Enabling KVM and/or media encryption will degrade performance. Enabling video compression
provides the fastest response while disabling compression provides better video quality.
For the best possible KVM performance, a 2Mb/sec link or higher is recommended.
The redirection of KVM over IP is performed in parallel with the local KVM without affecting the
local KVM operation.
9.1.3.4 Security
The KVM redirection feature supports multiple encryption algorithms, including RC4 and AES. The
actual algorithm that is used is negotiated with the client based on the client’s capabilities.
9.1.3.5 Availability
The remote KVM session is available even when the server is powered-off (in stand-by mode). No
re-start of the remote KVM session shall be required during a server reset or power on/off. A BMC
reset (for example, due to a BMC Watchdog initiated reset or BMC reset after BMC FW update) will
require the session to be re- established.
KVM sessions persist across system reset, but not across an AC power loss.
