Managing Remote Presence
This chapter includes the following sections:
Managing the Virtual KVM
KVM Console
The KVM console is an interface accessible from CIMC that emulates a direct keyboard, video, and mouse connection to the server. The KVM console allows you to connect to the server from a remote location. Instead of using CD/DVD or floppy drives physically connected to the server, the KVM console uses virtual media, which are actual disk drives or disk image files that are mapped to virtual CD/DVD or floppy drives. You can map any of the following to a virtual drive:
- CD/DVD or floppy drive on your computer
- Disk image files (ISO or IMG files) on your computer
- USB flash drive on your computer
Configuring the Virtual KVM
You must log in as a user with admin privileges to configure the virtual KVM.
This example configures the virtual KVM and displays the configuration:
Server# scope kvm Server /kvm # set enabled yes Server /kvm *# set encrypted no Server /kvm *# set kvm-port 2068 Server /kvm *# set max-sessions 4 Server /kvm *# set local-video yes Server /kvm *# commit Server /kvm # show detail KVM Settings: Encryption Enabled: no Max Sessions: 4 Local Video: yes Active Sessions: 0 Enabled: yes KVM Port: 2068 Server /kvm #
Launch the virtual KVM from the GUI.
Enabling the Virtual KVM
You must log in as a user with admin privileges to enable the virtual KVM.
This example enables the virtual KVM:
Server# scope kvm Server /kvm # set enabled yes Server /kvm *# commit Server /kvm # show Encryption Enabled Local Video Active Sessions Enabled KVM Port ------------------ ---------------- --------------- ------- -------- no yes 0 yes 2068 Server /kvm #
Disabling the Virtual KVM
You must log in as a user with admin privileges to disable the virtual KVM.
This example disables the virtual KVM:
Server# scope kvm Server /kvm # set enabled no Server /kvm *# commit Server /kvm # show Encryption Enabled Local Video Active Sessions Enabled KVM Port ------------------ ---------------- --------------- ------- -------- no yes 0 no 2068 Server /kvm #
Configuring Virtual Media
You must log in as a user with admin privileges to configure virtual media.
Command or Action | Purpose | |||
---|---|---|---|---|
Step 1 | Server# scope vmedia | Enters virtual media command mode. |
||
Step 2 | Server /vmedia # set enabled {yes | no} | Enables or disables virtual media. By default, virtual media is disabled.
|
||
Step 3 | Server /vmedia # set encrypted {yes | no} | Enables or disables virtual media encryption. |
||
Step 4 | Server /vmedia # commit | Commits the transaction to the system configuration. |
||
Step 5 | Server /vmedia # show [detail] | (Optional) Displays the virtual media configuration. |
This example configures virtual media encryption:
Server# scope vmedia Server /vmedia # set enabled yes Server /vmedia *# set encrypted yes Server /vmedia *# commit Server /vmedia # show detail vMedia Settings: Encryption Enabled: yes Enabled: yes Max Sessions: 1 Active Sessions: 0 Server /vmedia #
Use the KVM to attach virtual media devices to a host.
Managing Serial over LAN
Serial Over LAN
Serial over LAN (SoL) is a mechanism that enables the input and output of the serial port of a managed system to be redirected via an SSH session over IP. SoL provides a means of reaching the host console via CIMC.
Guidelines and Restrictions for Serial Over LAN
For redirection to SoL, the server console must have the following configuration:
- console redirection to serial port A
- no flow control
- baud rate the same as configured for SoL
- VT-100 terminal type
- legacy OS redirection disabled
The SoL session will display line-oriented information such as boot messages, and character-oriented screen menus such as BIOS setup menus. If the server boots an operating system or application with a bitmap-oriented display, such as Windows, the SoL session will no longer display. If the server boots a command-line-oriented operating system (OS), such as Linux, you may need to perform additional configuration of the OS in order to properly display in an SoL session.
In the SoL session, your keystrokes are transmitted to the console except for the function key F2. To send an F2 to the console, press the Escape key, then press 2.
Configuring Serial Over LAN
You must log in as a user with admin privileges to configure SoL.
Command or Action | Purpose | |||
---|---|---|---|---|
Step 1 | Server# scope sol | Enters SoL command mode. |
||
Step 2 | Server /sol # set enabled {yes | no} | Enables or disables SoL on this server. |
||
Step 3 | Server /sol # set baud-rate {9600 | 19200 | 38400 | 57600 | 115200} | Sets the serial baud rate the system uses for SoL communication.
|
||
Step 4 | Server /sol # commit | Commits the transaction to the system configuration. |
||
Step 5 | Server /sol # show [detail] | (Optional) Displays the SoL settings. |
This example configures SoL:
Server# scope sol Server /sol # set enabled yes Server /sol *# set baud-rate 115200 Server /sol *# commit Server /sol # show Enabled Baud Rate(bps) ------- --------------- yes 115200 Server /sol #
Launching Serial Over LAN
Command or Action | Purpose | |
---|---|---|
Step 1 | Server# connect host | Opens an SoL connection to the redirected server console port. You can enter this command in any command mode. |
Press Ctrl and X keys to disconnect from SoL and return to the CLI session.
Note |
When you enable SoL, the output from the serial port is redirected; therefore, when you try to session into the host from Cisco IOS CLI, you will not see any output. |
