Enabling a Standalone Fabric Interconnect for Cluster Configuration
Youcan add a second fabric interconnect to an existing Cisco UCS domain that uses a single standalone fabric
interconnect.To do this, you must enable the standalone fabric interconnect for cluster operation by configuring
itwith the virtual IP address of the cluster, and then add the second fabric interconnect to the cluster.
Procedure
PurposeCommand or Action
Enterslocal management mode.UCS-A#connect local-mgmt
Step 1
Enablescluster operation on thestandalone fabric interconnect
withthe specifiedIP address. Whenyou enterthis command,
UCS-A(local-mgmt)# enable
clustervirtual-ip-addr
Step 2
youare prompted to confirm that you want to enable cluster
operation.Type yes to confirm.
TheIP addressmust be the virtual IP addressfor the cluster
configuration,not the IP address assigned to the fabric
interconnectthat you are adding to the cluster.
Thefollowing example enables a standalone fabric interconnect with a virtual IP address of 192.168.1.101
forcluster operation:
UCS-A# connect local-mgmt
UCS-A(local-mgmt)# enable cluster 192.168.1.101
This command will enable cluster mode on this setup. You cannot change it
back to stand-alone. Are you sure you want to continue? (yes/no): yes
UCS-A(local-mgmt)#
What to Do Next
Addthe second fabric interconnect to the cluster.
Ethernet Switching Mode
TheEthernet switching mode determines how the fabric interconnect behaves as a switching device between
theservers and the network. The fabric interconnect operates in either of the following Ethernet switching
modes:
End-Host Mode
End-hostmode allows the fabric interconnect to act as an end host to the network, representing all server
(hosts)connected to it through vNICs. This is achieved by pinning (either dynamically pinned or hard pinned)
vNICsto uplink ports, which provides redundancy toward the network, and makes the uplink ports appear as
serverports to the rest of the fabric. When in end-host mode, the fabric interconnect does not run the Spanning
TreeProtocol (STP) and avoids loops by denying uplink ports from forwarding traffic to each other, and by
