NAME

fipvlan - Fibre Channel over Ethernet VLAN Discovery

SYNOPSIS

fipvlan -h|--help

fipvlan -v|--version

DESCRIPTION

The fipvlan command performs Fibre Channel over Ethernet (FCoE) Initialization Protocol (FIP) VLAN Discovery over Ethernet interfaces. fipvlan can be used as a diagnostic tool to determine which VLANs have FCoE services available on a network, prior to configuring VLAN interfaces and the Open-FCoE initiator. fipvlan can also be used to create VLAN interfaces as they are discovered, and to start the Open-FCoE initiator. The --create and --start options are primarily intended to be used as part of an Open-FCoE boot solution. FCoE instances started in this way cannot be destroyed or reset by fcoeadm.

fipvlan takes a list of network interface names to run the VLAN discovery protocol over, or the --auto option to use all available Ethernet interfaces.

fipvlan will enable any interface which is found disabled. If no response is received on that interface it will be shutdown again when fipvlan terminates.

OPTIONS

-a, --auto

: Use all Ethernet interfaces currently available

-c, --create

: Create network interfaces for discovered FCoE VLANs. If a VLAN device already exists for a discovered VLAN, a new VLAN device will not be created.

-d, --debug

: Enable debugging output

-s, --start

: Start the Open-FCoE initiator on discovered FCoE VLANs

-m, --mode

: fabric|vn2vn Specify whether VLAN discovery is performed in the default fabric mode, or in VN2VN mode.

-f, --suffix suffix

: Append the specified string suffix to VLAN interface names.

-l, --link-retry count

: Retry check for link up to count times. The link state is checked every 1000 ms. The default number of retries is 20.

-u, --link-up

: Leave link up if a FIP response has been received.

-h, --help

: Display a help message with basic usage instructions

-v, --version

: Display the fipvlan version string

VLAN NAMING CONVENTIONS

If a new VLAN device is created, it will have the name dev.vlan; where dev is the name of the Ethernet parent device and vlan is the discovered VLAN ID number. An optional suffix may be appended to this with the the -f command line option.

EXAMPLES

Display all discoverable VLANs with FCoE services

fipvlan --auto

Discover FCoE VLANs on interface eth2, create VLAN devices and start the Open-FCoE initiator

fipvlan --create --start eth2

In this example if FCoE services were available on VLAN 101 of network interface eth2, then a VLAN interface eth2.101 would be created and used as the parent device for the initiator.

SUPPORT
