Chapter: Managing Remote Presence

Managing Remote Presence

This chapter includes the following sections:

Configuring Serial Over LAN

Serial over LAN enables the input and output of the serial port of a managed system to be redirected over IP. Configure and use serial over LAN on your server when you want to reach the host console with Cisco IMC.


Important

You cannot use native serial redirection and serial over LAN simultaneously.

Before you begin

You must log in as a user with admin privileges to configure serial over LAN.

Procedure

Step 1

In the Navigation pane, click the Compute menu.

Step 2

In the Compute menu, select a server.

Step 3

In the work pane, click the Remote Management tab.

Step 4

In the Remote Presence pane, click the Serial over LAN tab.

Step 5

In the Serial over LAN Properties area, update the following properties:

Name Description

Enabled check box

If checked, Serial over LAN (SoL) is enabled on this server.

Baud Rate drop-down list

The baud rate the system uses for SoL communication. This can be one of the following:

  • 9600 bps

  • 19.2 kbps

  • 38.4 kbps

  • 57.6 kbps

  • 115.2 kbps

Com Port drop-down list

The serial port through which the system routes SoL communication.

Note 

This field is only available on some C-Series servers. If it is not available, the server always uses COM port 0 for SoL communication.

You can select one of the following:

  • com0—SoL communication is routed through COM port 0, an externally accessible serial port that supports either a physical RJ45 connection to an external device or a virtual SoL connection to a network device.

    If you select this option, the system enables SoL and disables the RJ45 connection, which means that the server can no longer support an external serial device.

  • com1—SoL communication is routed through COM port 1, an internal port accessible only through SoL.

    If you select this option, you can use SoL on COM port 1 and the physical RJ45 connection on COM port 0.

Note 

Changing the Com Port setting disconnects any existing SoL sessions.

Note 

This option is available only on some C-Series servers.

SSH Port filed

The port through which you can access Serial over LAN directly. The port enables you to by-pass the Cisco IMC shell to provide direct access to SoL.

The valid range is 1024 to 65535. The default value is 2400.

Note 

Changing the SSH Port setting disconnects any existing SSH sessions.

Step 6

Click Save Changes.

Configuring Virtual Media

Before you begin

You must log in as a user with admin privileges to configure virtual media.

Procedure

Step 1

In the Navigation pane, click the Compute tab.

Step 2

In the Compute tab, click the Remote Management tab.

Step 3

In the Remote Management tab, click the Virtual Media tab.

Step 4

In the Virtual Media Properties area, update the following properties:

Name Description

Enabled check box

If checked, virtual media is enabled.

Note 

If you clear this check box, all virtual media devices are automatically detached from the host.

Active Sessions field

The number of virtual media sessions that are currently running.

Enable Virtual Media Encryption check box

If checked, all virtual media communications are encrypted.

Low Power USB enabled check box

If checked, low power USB is enabled.

If the low power USB is enabled, after mapping the ISO and rebooting the host, the virtual drives appear on the boot selection menu.

But, while mapping an ISO to a server that has a UCS VIC P81E card and the NIC is in Cisco Card mode, this option must be disabled for the virtual drives to appear on the boot selection menu.

Step 5
