Hi Dave,
We have a similar number of VLANs across our operations and there is no debate around the need for the VLANs and their separation. My question is more around whether a VM (e.g. Linux) would connect to many VLANs or only one VLAN. E.g. you say you have a System Management VLAN and then say a DMZ VLAN. If a VM is a web server running apache and sits in the DMZ VLAN, where would the ssh traffic to that same VM go? Would it have an IP on the Management VLAN on which SSH listens, and then another IP in the DMZ VLAN on which it does the HTTP traffic? or/ would you say that its primary function is a web server and thus both HTTP and SSH traffic goes on the DMZ VLAN

fipvlan
FIPVLAN(8) Open-FCoE Tools FIPVLAN(8)
NAME
fipvlan - Fibre Channel over Ethernet VLAN Discovery
SYNOPSIS
fipvlan [-c|--create] [-s|--start] interfaces
fipvlan -a|--auto [-c|--create] [-d|--debug] [-s|--start] [-l|--link-retry <num>]
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 to be not enabled by the time the program runs. 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
-f, --suffix <suffix string>
Append the specified string <suffix string> to VLAN interface names.
-l, --link-retry <number of retries>
Retry check for link up up to <number of retries> times. The link state is retried every 500 ms. The default is 20.
-h, --help
Display a help message with basic usage instructions
-v, --version
Display the fipvlan version string
VLAN NAMING CONVENTIONS
The default VLAN device name is dev.vlan; where dev is the name of the Ethernet parent device and vlan is the discovered VLAN ID number. An
optional suffix can be appended to this with -f commandline 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-fcoe would be created
and used as the parent device for the initiator.
