BMC VLAN Tagging Support

The BMC supports VLAN (Virtual LAN) tagging for network traffic. VLANs are configured on the
network switch and are given a VLAN ID or tag. Ports on the switch can belong to one or more
VLAN and can have one of the following VLAN settings:
• Tagged — The packets coming out of the switch port contain the VLAN tag. In this case you
should enable VLAN tags on the BMC and set the BMC VLAN tag (or ID) to the same value
as the switch port. Otherwise the BMC will not respond to incoming network traffic. Note
that setting a VLAN tag on the BMC also causes the BMC to insert the VLAN tag to all
outgoing network packets.
• Untagged — The packets coming out of the switch port do not contain the VLAN tag. In this
case you should disable VLAN tags on the BMC. By default, VLAN tags are disabled on the
BMC.
NOTE:See the Dell PowerConnect 5316M CLI Reference Guide for more information about using
the VLAN commands.
Network Connectivity After Restart or Power-up
After the server chassis is powered-up or the PowerConnect™ 5316M Ethernet Switch Module
(ESM) is rebooted or power cycled, the ESM will require approximately one minute and forty-five
seconds to become fully operational. In addition, the ESM may require up to sixty seconds to
establish the links to external Ethernet devices if the spanning tree protocol is enabled on the
external ports of the ESM. See the
Dell PowerConnect 5316M Systems Getting Started Guide
for
information on how to determine when the ESM is fully operational.
Integrated Mirroring Configurations
The following items provide updates for setting up and using integrated mirroring:
• The hard-drive status indicator does not display any status information until after the
operating system driver initialization has occurred. To check for status information of a hard
drive prior to operating system load, use <Ctrl><m> during POST. See the
Dell PowerEdge
Expandable RAID Controller 4/IM User’s Guide
for more information. During normal
operation, the status indicator is off.
NOTE:The hard-drive activity indicator functions normally before and after the operating system
driver initialization.
NOTICE:If you use a drive with existing data, the data will be cleared before the hard drive is added to a
mirror.
• It is recommended that any replacement drives should be blank and not previously
configured.
• It is recommended that you replace hard drives in an integrated-mirror configuration with
drives of the same capacity.
