Re: Vif Configuration

Hi Nayab,

The links Michael provided are very informative and gives you a great exposure towards VIF's creation and its concepts. But to give you high-level understanding on its functionality I will take couple of minutes to explain here:

Netapp MM (multi-mode) VIFs allow you to add reliability and performance to the filer's networking configuration. You can do it in multiple ways on NetApp filers:

1. Ethernet trunking, bonding, Etherchanneling or port channeling (Cisco).

2. The aggregation of multiple physical links gives us one big fast and high availability link. 

3. A MultiMode VIF is NetApp’s term for EtherChannel or Port Channeling.

Defined Types:

Static MultiMode VIF

======================

1. Hard coded or static EtherChannel, the ports do not negotiate, there is no auto detection of the physical port status.

2. Static etherchannel has to be enabled on each port on the switch.

Myfiler> vif create multi

Dynamic MultiMode VIF

======================

1. It is a LACP EtherChanel. (IEEE 802.3ad)

2. This is intelligent and will take actions appropriately when a link is down, it sends a notification from switch to filer that a interface was removed. (which donot happend in static mode)

Myfiler> vif create lacp

Load Balancing Options:

=======================

MAC Load-Balancing

Round Robin

Source and Destination Pairs

IP based Load Balanding

Examples:

========

1. Setup Static MultiMode VIF using e0a-d.

myfiler> vif create multi vif01 -b ip e0a e0b e0c e0d

myfiler> ifconfig vif01 172.28.45.10 netmask 255.255.255.0 mtusize 1500 partner cisco-partner-001

myfiler> ifconfig vif01 alias 172.28.45.11 netmask 255.255.255.0

myfiler> ifconfig vif01 alias 172.28.45.12 netmask 255.255.255.0

myfiler> ifconfig vif01 alias 172.28.45.13 netmask 255.255.255.0

2. Setup LACP Dynamic MultiMode VIF using e0a-d.

myfiler> vif create lacp vif01 -b ip e0a e0b e0c e0d

myfiler> ifconfig vif01 172.28.45.10 netmask 255.255.255.0 mtusize 1500 partner cisco-partner-001

myfiler> ifconfig vif01 alias 172.28.45.11 netmask 255.255.255.0

myfiler> ifconfig vif01 alias 172.28.45.12 netmask 255.255.255.0

myfiler> ifconfig vif01 alias 172.28.45.13 netmask 255.255.255.0
