Conguring 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 conguring 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.
Conguring Management Port 2 using CMC web interface
To congure 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 Conguration 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.
Conguring 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.
