Managing Network Adapters  
This chapter includes the following sections:  
Overview of the Cisco UCS C-Series Network Adapters  
Note  
The procedures in this chapter are available only when a Cisco UCS C-Series network adapter is installed  
in the chassis.  
A Cisco UCS C-Series network adapter can be installed to provide options for I/O consolidation and  
virtualization support. The following adapters are available:  
• Cisco UCS P81E Virtual Interface Card  
• Cisco UCS VIC1225 Virtual Interface Card  
The interactive UCS Hardware and Software Interoperability Utility lets you view the supported components  
and configurations for a selected server model and software release. The utility is available at the following

Managing vHBAs  
Managing vHBAs  
Guidelines for Managing vHBAs  
When managing vHBAs, consider the following guidelines and restrictions:  
• The Cisco UCS P81E Virtual Interface Card and Cisco UCS VIC1225 Virtual Interface Card provide  
two vHBAs (fc0 and fc1). You can create up to 16 additional vHBAs on these adapter cards.  
Note  
If Network Interface Virtualization (NIV) mode is enabled for the adapter, you must  
assign a channel number to a vHBA when you create it.  
• When using the Cisco UCS P81E Virtual Interface Card or Cisco UCS VIC1225 Virtual Interface Card  
in an FCoE application, you must associate the vHBA with the FCoE VLAN. Follow the instructions  
in Modifying vHBA Properties, on page 11 to assign the VLAN.  
• After making configuration changes, you must reboot the host for settings to take effect.

Managing vNICs  
Guidelines for Managing vNICs  
When managing vNICs, consider the following guidelines and restrictions:  
• The Cisco UCS P81E Virtual Interface Card and Cisco UCS VIC1225 Virtual Interface Card provide  
two default vNICs (eth0 and eth1). You can create up to 16 additional vNICs on these adapter cards.  
Note  
If Network Interface Virtualization (NIV) mode is enabled for the adapter, you must  
assign a channel number to a vNIC when you create it.  
• After making configuration changes, you must reboot the host for settings to take effect.
