For information about configuring CMC network settings, see Configuring Initial CMC Network. This initial configuration assigns
the TCP/IP networking parameters that enable access to CMC.
CMC and iDRAC on each server and the network management ports for the switch I/O module are connected to a common
integrated network in the PowerEdge VRTX chassis. This allows the management network to be isolated from the server data
network. It is important to separate this traffic for uninterrupted access to chassis management.
CMC is connected to the management network. All external access to CMC and iDRACs is achieved through CMC. Access
to the managed servers, conversely, is accomplished through network connections to the I/O module (IOM). This allows the
application network to be isolated from the management network.
It is recommended to isolate chassis management from the data network. Due to the potential of traffic on the data network,
the management interfaces on the internal management network can be saturated by traffic intended for servers. This results in
CMC and iDRAC communication delays. These delays may cause unpredictable chassis behavior, such as CMC displaying iDRAC
as offline even when it is up and running, which in turn causes other unwanted behavior. If physically isolating the management
network is impractical, the other option is to separate CMC and iDRAC traffic to a separate VLAN. CMC and individual iDRAC
network interfaces can be configured to use a VLAN.
Configuring Initial CMC Network
NOTE: Changing your CMC Network settings may disconnect your current network connection.
You can perform the initial network configuration of CMC before or after CMC has an IP address. If you configure CMC’s initial
network settings before you have an IP address, you can use either of the following interfaces:
● The LCD panel on the front of the chassis
● Dell CMC serial console
If you configure initial network settings after the CMC has an IP address, you can use any of the following interfaces:
● Command line interfaces (CLIs) such as a serial console, Telnet, SSH, or the Dell CMC console.
● Remote RACADM
● CMC web interface
● LCD Panel interface
CMC supports both IPv4 and IPv6 addressing modes. The configuration settings for IPv4 and IPv6 are independent of each
other.
Configuring CMC Network Using LCD Panel Interface
You can use the LCD panel interface to set up the CMC network.
NOTE:
You can customize the orientation of an LCD display (for rack or tower mode) by keeping the up-down buttons
pressed for two seconds. Alternately, you can also use the right-left buttons. For more information about the buttons
available on a CMC LCD panel, see LCD Navigation.
1. To start the CMC configuration:
● For a chassis that has not been configured earlier, the LCD Language panel is displayed. On the LCD Language panel,
navigate to the required language using the arrow buttons. When the desired language is highlighted, select the language
by pressing the Center button. The Network Settings panel is displayed.
● For a chassis that has been configured earlier, the Main Menu panel is displayed. From the Main Menu, select Settings
and then Network Settings.
2. On the Network Settings panel, select the required mode of setup:
● Quick Setup (DHCP) — Select this mode to set up CMC quickly using DHCP addresses. For information on configuring
CMC using this mode see Configuring CMC Using Quick Setup (DHCP).
● Advanced Setup — Select this mode to set up CMC for advanced configurations. For information on configuring CMC
using this mode see Configuring CMC Using Advanced Setup.
