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.
5.5.3 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.
5.5.4 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.
5.5.5 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.
5.5.6 Usage
As the server is powered up, the remote KVM session displays the complete BIOS boot
process. The user is able interact with BIOS setup, change and save settings as well as enter
and interact with option ROM configuration screens.
