Multiple IP over single interface

SANTOSH_DEV — Thu, 05 Jun 2025 06:10:04 GMT

In FAS 2240 filer I am having 2 number 10 GB ports. Here I want to distrubute CIFS and NFS traffic over different VLAN.

I have to configure multiple IP over single interface . There is any optionavailable on Data Ontap for this configuration.

I have read one article for configurating alian over interface.

If I configure alis whether this will work for two different IP with different subnet.

I think if you are creating a VLAN, then why do you need alias? I haven't worked on 10G mezzanine ethernet ports, but I think it is a dual port on each head. I suggest you create a ifgrp single mode (failover) and add respective VLANs to it.

Example:
If you are creating vif: (single mode:Active/Passive failover)
ifgrp create single vif1 e1a e1b
vlan create vif1 10 (NFS)
vlan add vif1 20 (CIFS)

ifconfig vif1-10 192.168.10.2 netmask 255.255.255.0 mtusize 1500 partner vif1-10 nfo
ifconfig vif1-20 192.168.20.2 netmask 255.255.255.0 mtusize 1500 partner vif1-20 nfo

If you are not creating vif:
vlan create e1a 10 (NFS)
vlan add e1a 20 (CIFS)
ifconfig e1a-10 192.168.10.2 netmask 255.255.255.0 mtusize 1500 partner e1a-10 nfo
ifconfig e1a-20 192.168.20.2 netmask 255.255.255.0 mtusize 1500 partner e1a-20 nfo
