Cisco Nexus 5000 Series and Cisco Nexus 2000 Series Release Notes, for Cisco NX-OS Release 5.0(2)N1(1) and NX-OS Release 5.0(2)N2(1)
OL-22747-02
New and Changed Features
Hardware Features
Cisco NX-OS Release 5.0(2)N1(1) includes the following new or changed hardware features:
• Support for the Cisco Nexus 5548P Platform switch which is a 1 RU chassis with 32 fixed ports and
1 expansion slot.
• Support for the following modules:
– 16-port 1/10-Gigabit Ethernet and FCoE GEM
– 8-port 1/10-Gigabit Ethernet and FCoE plus an 8-port 8/4/2/1 native FC GEM
• Support for Cisco Nexus 2000 Series Fabric Extenders on the Cisco Nexus 5548 switch.
• Support for 4000 VLANs per Cisco Nexus 5500 Platform switch.
Software Features
Cisco NX-OS Release 5.0(2)N1(1) includes the following new or changed software features:
• Configuration Synchronization (config-sync)
Caution For additional information and best practices that must be followed when using the configuration
synchronization feature, see the “Configuration Synchronization Operations” chapter in the Cisco Nexus
5000 Series Operations Guide at the following URL:
http://www.cisco.com/en/US/docs/switches/datacenter/nexus5000/sw/operations/n5k_ops_guide.html
Failure to do so may leave configurations in an inconsistent state.
Config-sync allows you to make configuration changes on one switch and have the system
automatically synchronize the switch’s peers. This feature eliminates user errors and reduces the
administrative overhead of having to configure both members of a virtual port channel (vPC)
simultaneously.
• Module Preprovisioning
Module preprovisioning allows you to preconfigure interfaces before inserting or attaching a
module to a Cisco Nexus 5000 Series switch. If a module goes offline, you can use preprovisioning
to make changes to the interface configurations for the offline module. Preprovisioning allows you
to synchronize the configuration for an interface that is online with one peer but offline with another
peer.
• Port profiles
A port profile is a container used to define a common set of network configuration commands for
multiple interfaces. This feature enables you to define port configurations across a large number of
ports.
• Configuration Rollback
A configuration rollback provides the ability to revert a running configuration to a previously saved
configuration snapshot or checkpoint.
• Private VLANs over Port Channel and vPC Interfaces
This feature allows you to configure a promiscuous trunk (or isolated trunk) on port channel or vPC
interfaces.
• Access control list (ACL) on a virtual terminal (VTY)
