Re: How to bind Autosupport traffic to a specific interface only?

neves_jacques · ‎2012-09-19

Hi,

I've got a FAS2220 running 8.1.1 with the following network configuration (here below /etc/rc file):

---------------------------------------------

hostname xxxx

ifgrp create lacp MultiTrunk -b ip e0a e0b e0c e0d

vlan create MultiTrunk 85

ifconfig MultiTrunk `hostname`-MultiTrunk netmask 255.255.0.0 mtusize 9000 partner MultiTrunk

ifconfig MultiTrunk-85 `hostname`-MultiTrunk-85 netmask 255.255.255.0 mtusize 9000 partner MultiTrunk-85

route add default 172.16.1.250 1

routed on

options dns.domainname xxxx.yyy

otions dns.enable on

otions nis.enable off

savecore

---------------------------------------------

The autosupport traffic is using the interface MultiTrunk-85 (network 192.168.85 /24 == IP_SAN VLAN) not the default interface MultiTrunk (with default gateway 172.16.1.250).

I do wish to bind the autosupport traffic on the MultiTrunk interface (network 172.16 /16 == Production VLAN).

Any ideas?

Thanks in advance,

JNV

What is IP address of default mailhost? Please show “netstat -rn” output.

neves_jacques · ‎2012-09-19

Hi,

The default mailhost is on a different VLAN (192.168.132.xx).

Regards,

JNV

Please show output of “netstat -rn” and “ifconfig -a”. Network questions cannot be answered based on XX.

According to this packages for 192.168.132.70 should be using MultiTrunk. Where do you see that it is using MultiTrunk-85?

neves_jacques · ‎2012-09-19

On the firewall, we do see SMTP traffic from MultiTrunk-85...

If I put the MultiTrunk-85 down only then Autosupport is using MultiTrunk.

Strange ;-(
