Chapter 13 Configuring N Port Virtualization About NPV Send documentation comments to [email protected] Figure 13-2 Cisco NPV Configuration-Interface View Host N-Port NPV Device F-Port NP-Port F-Port NPV Core Switch N-Port Host F-Port NP-Port NPV Device F-Port NPIV enable 184631 NPV Mode A switch is in NPV mode after a user has enabled NPV and the switch has successfully rebooted. NPV mode applies to an entire switch. All end devices connected to a switch that is in NPV mode must log in as an N port to use this feature (loop-attached devices are not supported). All links from the edge switches (in NPV mode) to the NPV core switches are established as NP ports (not E ports), which are used for typical interswitch links. NPIV is used by the switches in NPV mode to log in to multiple end devices that share a link to the NPV core switch. Note In-order data delivery is not required in NPV mode because the exchange between two end devices always takes the same uplink to the core from the NPV device. For traffic beyond the NPV device, core switches will enforce in-order delivery if needed and/or configured. After entering NPV mode, only the following commands are available: aaa arp banner boot callhome cli clock do end exit fcanalyzer fcrxbbcredit fips hw-module interface ip ipv6 line logging no npv ntp port-track power poweroff radius radius-server Configure aaa functions [no] remove an entry from the ARP cache Configure banner message Configure boot variables Enter the callhome configuration mode CLI configuration commands Configure time-of-day clock EXEC command Exit from configure mode Exit from configure mode Configure cisco fabric analyzer Enable extended rx b2b credit configuration Enable/Disable FIPS mode Enable/Disable OBFL information Select an interface to configure Configure IP features Configure IPv6 features Configure a terminal line Modify message logging facilities Negate a command or set its defaults Config commands for FC N_port Virtualizer NTP Configuration Configure Switch port track config Configure power supply Poweroff a module in the switch Configure RADIUS configuration Configure RADIUS related parameters OL-16184-01, Cisco MDS SAN-OS Release 3.x Cisco MDS 9000 Family CLI Configuration Guide 13-3

Configuring N Port Virtualization

About NPV

Figure 13-2

Cisco NPV Configuration–Interface View

NPV Mode

A switch is in NPV mode after a user has enabled NPV and the switch has successfully rebooted. NPV

mode applies to an entire switch. All end devices connected to a switch that is in NPV mode must log in

as an N port to use this feature (loop-attached devices are not supported). All links from the edge

switches (in NPV mode) to the NPV core switches are established as NP ports (not E ports), which are

used for typical interswitch links. NPIV is used by the switches in NPV mode to log in to multiple end

devices that share a link to the NPV core switch.

Note

In-order data delivery is not required in NPV mode because the exchange between two end devices

always takes the same uplink to the core from the NPV device. For traffic beyond the NPV device, core

switches will enforce in-order delivery if needed and/or configured.

After entering NPV mode, only the following commands are available:

aaa
