Ifgroup Trunk Configuration

SWEETMANA — Thu, 05 Jun 2025 06:20:24 GMT

Hi,

I have a customer who is a SP and require multiple Vlans for there NAS requirements. i.e they use seperate VLAN's for each customer to access CIFS/NFS.

The configuration I had in mind was for each head in a HA pair to create an IFgroup which supported Cisco trunking dot1q?

I plan to configure IFGroups for SnapMirror and SnapVault using LACP to provide Dynamic fault tolerance and load balancing as they will be connected via a port channel using a single VLAN.

What configuration would I have to adopt to allow multiple VLANS to service NAS for their different customers? also is it posible to provide load balacing for trunked ports?

Many Thanks

Austin

Hey Austin,

Check out this document

http://www.netapp.com/templates/mediaView?m=tr-3802.pdf&cc=us&wid=83443832&mid=29853432

If you still have questions after reading through this let me know.

I would create an ifgrp for NFS and tag all the vlans

Here is an example of what the RC file would look like,

hostname test

ifgrp create lacp NFS -b ip e1a e1b

vlan create NFS 11 106

ifconfig NFS-11 192.168.10.56 netmask 255.255.255.224 partner NFS-02-11 mtusize 1500

ifconfig NFS-106 192.168.5.48 netmask 255.255.255.0 partner NFS-02-106 mtusize 1500

ifconfig NFS-106 alias 192.168.5.50 netmask 255.255.255.0 partner NFS-02-106 mtusize 1500

route add default 192.168.5.1

routed on

options dns.domainname test.local

options dns.enable on

options nis.enable off

savecore

Also, how many Ethernet ports are we working with?

Hi Thanks for your quick response,

At present we have 2 ports per head for NAS but will plan for the expansion of this in the future. From what you have sent me this is perfect! Thanks for this, it expains what I had already envisaged.
