About this task
The following steps should be inserted after the existing Step 1 ("Ensure that
your HA pair is optimally configured and functioning correctly").
Procedure
1. Ensure that network ports are up and functioning correctly by entering the
following command:
ifconfig -a
Example
For each interface, you see a display similar to the following:
e0a: flags=0x2f4c867<UP,BROADCAST,RUNNING,MULTICAST,TCPCKSUM,LINK_UP> mtu 1500
inet 192.9.200.41 netmask 0xffffff00 broadcast 192.9.200.255
partner e0a 192.9.200.42
ether 00:0c:29:56:54:7e (auto-1000t-fd-up) flowcontrol full
For each interface that serves data traffic, you must ensure that each of the
following is true:
v The interface has a partner that also serves data; that is, the partner is
not an e0M or e0P interface.
v The link to the local interface is up.
v The mtu parameter settings are the same for both partners.
v Partnered interfaces are on the same LAN (the same broadcast domain).
For example, an interface named e0a-10 should be partnered only with
another VLAN with tag 10, such as e0b-10.
v Partnered interfaces have matching settings for the
interface.blocked.protocol option.
For example, if CIFS is blocked on e0a and e0a is partnered with e0b,
CIFS should also be blocked on e0b.
If your system includes multiple interface groups, you might also want to
confirm their activity with the ifgrp status command.
2. If you have edited the /etc/rc file, ensure that entries are listed in the
following order:
hostname system_name
ifgrp[commands]
vlan [commands]
ifconfig [commands]
vfiler [commands]
route [commands]
[any other commands]
3. If your systems include e0M management interfaces, ensure that they are
serving only management traffic on a dedicated management LAN or that
