Configuring Port Modes for a 6248 Fabric Interconnect
Changing the port mode on either module can cause an interruption in data traffic because changes to the
fixed module require a reboot of the fabric interconnect and changes on an expansion module require a
reboot of that module.
If the Cisco UCS domain has a cluster configuration that is set up for high availability and servers with
service profiles that are configured for failover, traffic fails over to the other fabric interconnect and data
traffic is not interrupted when the port mode is changed on the fixed module.
Caution
Procedure
Step 1
In the Navigation pane, click the Equipment tab.
Step 2
On the Equipment tab, expand Equipment > Fabric Interconnects > Fabric_Interconnect_Name.
Step 3
In the Work pane, click the General tab.
Step 4
In the Actions area of the General tab, click Configure Unified Ports.
Step 5
Review the confirmation message and click one of the following:
• Yes—To continue with configuring the port mode.
• No—To exit without configuring the port mode and wait for an appropriate maintenance window.
Step 6
Click one of the following buttons to choose the module for which you want to configure the port modes:
• Configure Fixed Module
• Configure Expansion Module
Step 7
Use your mouse to drag the slider along the bar until the displays shows the port mode configuration that you
want for the module.
If you change the port mode for a previously configured port, the port returns to an unconfigured state.
Step 8
If you need to configure port modes for the other module, repeat Steps 6 and 7.
Step 9
Click Finish to save your port mode configuration.
Depending upon the module for which you configured the port modes, data traffic for the Cisco UCS domain
is interrupted as follows:
• Fixed module—The fabric interconnect reboots. All data traffic through that fabric interconnect is
interrupted. In a cluster configuration that provides high availability and includes servers with vNICs
that are configured for failover, traffic fails over to the other fabric interconnect and no interruption
occurs.
It takes about 8 minutes for the fixed module to reboot.
• Expansion module—The module reboots. All data traffic through ports in that module is interrupted.
It takes about 1 minute for the expansion module to reboot.
