Configuring Management Port 2
The second network port on the CMC can be used for daisy-chaining CMCs together for cable reduction, or as a redundant
port for failover networking operation. Management Port 2 may be connected to the top-of-rack (TOR) switch or to another
switch. There is no requirement that the two CMC NIC ports be connected to the same subnet.
The CMC cannot be cabled for Management Network Port redundancy prior to actually configuring it for this operation. The
CMC must use the standard single network connection for deployment, after which the second redundant connection may be
made.
NOTE: When Management Port 2 is set for Redundant but is cabled for Stacking, the downstream CMCs (further from the
TOR switch) will not have a network link.
NOTE: When Management Port 2 is set for Stacking but is cabled for Redundant (two connections to the TOR switch),
routing loops could cause a network storm.
To specify Redundant operation, use racadm config –g cfgNetTuning –o cfgNetTuningNicRedundant 1
command.
To specify Stacking operation, use racadm config –g cfgNetTuning –o cfgNetTuningNicRedundant 0
command.
By default, the Management Port 2 is set for Stacking.
Configuring Management Port 2 using CMC web interface
To configure Management Port using CMC Web Interface:
1. In the left pane, click Chassis Overview > Network, and then click the Network tab.
2. On the Network Configuration page, in the General Settings section, next to Management Port 2, select either
Redundant or Stacking.
3. Click Apply Changes.
● When Management Port 2 is set for Redundant but is cabled for Stacking, the downstream CMCs (further from the
top-of-rack switch) does not have a network link.
● When Management Port 2 is set for Stacking but is cabled for Redundant (two connections to the TOR switch), routing
loops could cause a network storm.
Configuring Management Port 2 using RACADM
To specify Redundant operation, use racadm config –g cfgNetTuning –o cfgNetTuningNicRedundant 1
command.
To specify Stacking operation, use racadm config –g cfgNetTuning –o cfgNetTuningNicRedundant 0
command.
By default, the Management Port 2 is set for Stacking.
Federal Information Processing Standards
The agencies and contractors of the Federal government of the United States use Federal Information Processing Standards
(FIPS), a computer security standard, which is related to all applications that have communicative interfaces. The 140–2
comprises of four levels — Level 1, Level 2, Level 3, and Level 4. The FIPS 140–2 series stipulate that all communicative
interfaces must have the following security properties:
● authentication
● confidentiality
● message integrity
● non-repudiation
● availability
