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.
