MAC Address - Four Interfaces with the same MAC Address
four interfaces with ifconfig
all interfaces have the same mac. If is not set for unique.
but it still works.
what difference does it make to have all macs the same or different?

Hi,
I've got a Sun Solaris machine with host ID (840f8e57) and MAC address (0:14:4f:f:8e:57), how do I:
1. Write the MAC address in standard (IEEE 802) format, i.e. xx-xx-xx-xx-xx-xx? Do I need to add 0's before or after the 'f', i.e. 00-14-4f-0f-8e-57 or 00-14-4f-f0-8e-57?

vlan-interfaces
VLAN-INTERFACES(5) File formats VLAN-INTERFACES(5)
NAME
/etc/network/interfaces (vlan) - vlan extensions for the interfaces(5) file format
DESCRIPTION
/etc/network/interfaces contains network interface configuration information for the ifup(8) and ifdown(8) commands. This manpage
describes the vlan extensions to the standard interfaces(5) file format.
Primary extensions exist to make and destroy vlan interfaces, secondary extensions exist for ipv4 interface manipulation which are gener-
ally needed when using (a lot of) vlans.
VLAN CREATION
Vlan interface definitions exist of the vlan interface name, and an optional 'raw-device' parameter. Vlan interfaces are numbered 1 to
4095. You have the option to have interface names zero-padded to 4 numbers, or just the plain digits without leading zero. The following
example shows four ways to create a vlan with id 1 on interface eth0. They all result in different names.
iface eth0.1 inet static
address 192.168.1.1
netmask 255.255.255.0
iface vlan1 inet static
vlan-raw-device eth0
address 192.168.1.1
netmask 255.255.255.0
iface eth0.0001 inet static
address 192.168.1.1
netmask 255.255.255.0
iface vlan0001 inet static
vlan-raw-device eth0
address 192.168.1.1
netmask 255.255.255.0
# We don't have br support out of the box
iface br0.2 inet static
vlan-raw-device br0
address 192.168.1.1
netmask 255.255.255.0
# Aliases are ignored
iface br0.2:1 inet static
address 192.168.1.1
netmask 255.255.255.255
EXTRA IFACE OPTIONS
Usually someone who uses vlans also wants to do some other manipulations with the ip stack or interface.
vlan-raw-device devicename
Indicates the device to create the vlan on. This is ignored when the devicename is part of the vlan interface name.
ip-proxy-arp 0|1
Turn proxy-arp off or on for this specific interface. This also works on plain ethernet like devices.
ip-rp-filter 0|1|2
Set the return path filter for this specific interface. This also works on plain ethernet like devices.
hw-mac-address mac-address
This sets the mac address of the interface before bringing it up. This works on any device that allows setting the hardware address
with the ip command.
