Virtual Local Area Network (VLAN)
The BMC supports VLAN as defined by IPMI 2.0 specifications. VLAN is supported internally by
the BMC, not through switches. VLAN provides a way of grouping a set of systems together so
that they form a logical network. This feature can be used to set up a management VLAN where
only devices which are members of the VLAN will receive packets related to management and
members of the VLAN will be isolated from any other network traffic. Please note that VLAN
does not change the behavior of the host network setting, it only affects the BMC LAN
communication.
LAN configuration options are now supported (by means of the Set LAN Config Parameters
command, parameters 20 and 21) that allow support for 802.1Q VLAN (Layer 2). This allows
VLAN headers/packets to be used for IPMI LAN sessions. VLAN ID’s are entered and enabled
by means of parameter 20 of the Set LAN Config Parameters IPMI command. When a VLAN ID
is configured and enabled, the BMC only accepts packets with that VLAN tag/ID. Conversely, all
BMC generated LAN packets on the channel include the given VLAN tag/ID. Valid VLAN ID’s
are 1 through 4094, VLAN ID’s of 0 and 4095 are reserved, per the 802.1Q VLAN specification.
Only one VLAN can be enabled at any point in time on a LAN channel. If an existing VLAN is
enabled, it must first be disabled prior to configuring a new VLAN on the same LAN channel.
Parameter 21 (VLAN Priority) of the Set LAN Config Parameters IPMI command is now
implemented and a range from 0-7 will be allowed for VLAN Priorities. Please note that bits 3
and 4 of Parameter 21 are considered Reserved bits.
Parameter 25 (VLAN Destination Address) of the Set LAN Config Parameters IPMI command is
not supported and returns a completion code of 0x80 (parameter not supported) for any
read/write of parameter 25.
If the BMC IP address source is DHCP, then the following behavior is seen:

If the BMC IP address source is DHCP, then the following behavior is seen:
If the BMC is first configured for DHCP (prior to enabling VLAN), when VLAN is enabled,
the BMC performs a discovery on the new VLAN in order to obtain a new BMC IP address.
If the BMC is configured for DHCP (before disabling VLAN), when VLAN is disabled, the
BMC performs a discovery on the LAN in order to obtain a new BMC IP address.
If the BMC IP address source is Static, then the following behavior is seen:
If the BMC is first configured for static (prior to enabling VLAN), when VLAN is enabled,
the BMC has the same IP address that was configured before. It is left to the management
application to configure a different IP address if that is not suitable for VLAN.

6.12.7
Secure Shell (SSH)
Secure Shell (SSH) connections are supported for SMASH-CLP sessions to the BMC.
6.12.8
Serial-over-LAN (SOL 2.0)
The BMC supports IPMI 2.0 SOL.
IPMI 2.0 introduced a standard serial-over-LAN feature. This is implemented as a standard
payload type (01h) over RMCP+.
