6.10.4
Address Resolution Protocol (ARP)
The BMC can receive and respond to ARP requests on BMC NICs. Gratuitous ARPs are supported, and
disabled by default.
6.10.5
Internet Control Message Protocol (ICMP)
The BMC supports the following ICMP message types targeting the BMC over integrated NICs:
 Echo request (ping): The BMC sends an Echo Reply.
 Destination unreachable: If message is associated with an active socket connection within the BMC, the
BMC closes the socket.
6.10.6
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 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.
 If the BMC is configure for static (prior to disabling VLAN), when VLAN is disabled, 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 LAN.
6.10.7
Secure Shell (SSH)
Secure Shell (SSH) connections are supported for SMASH-CLP sessions to the BMC.
6.10.8
Serial-over-LAN (SOL 2.0)
The BMC supports IPMI 2.0 SOL.
