Sixteen of the forty fixed ports support both GE and 10GE. The default is 10GE.

No configuration is allowed on member ports. All member ports follow the configuration on the EtherChannel.

1/1 Virtual interface groups have been deprecated in release 4.0(1a)N1(1). Virtual Ethernet Interfaces Cisco NX-OS Release 4.0(1a)N1(1) does not support virtual Ethernet interfaces.

Changes to the FCoE Model and Related Configuration Send documentation comments to [email protected] VSAN-to-VLAN Mapping In previous Cisco NX-OS 4.0(0)-based releases, FCoE had no dependence on the VLANs defined on the switch.

NX-OS software supports only a single type of VACL (either MAC, IPv4, or IPv6) applied on a VLAN. • Multiple boot kickstart statements in the configuration are not supported. • If you remove an expansion module with Fibre Channel - HP Cisco MDS 9124 | Cisco Nexus 5000 Series Release Notes, Release 4.0(1a)N1(1) - Page 11
up properly unless the default VRF is configured. Workaround: The Cisco Nexus 5000 Series switches support two possible VRFs, the default and the management. Configure the desired VRF when using TACACS+ service. You can configure the desired VRF using either of these configurations: aaa group server - HP Cisco MDS 9124 | Cisco Nexus 5000 Series Release Notes, Release 4.0(1a)N1(1) - Page 12
