Networking Issues

This section describes the networking issues in the Oracle Solaris 11 release.

cxge Driver Alias Conflicts With an Existing Driver Alias (7054074)

The following warning is displayed in the system log file:

WARNING: Driver alias "cxge" conflicts with an existing driver name or alias.

Workaround: Ignore the warning.

dladm show-aggr Command With the -s Option Does Not Work (7094923)

Link aggregations in Oracle Solaris can be administered by using the dladm subcommands. The dladm show-aggr command with the -s can be used to query statistics counters for the network traffic flowing through an aggregation.

In this release, the dladm command with the show-aggr subcommand does not work as expected. You will not see any error message, but the dladm show-aggr command with the -s option always reports zero for all statistics counters.

Workaround: Choose one of the following workarounds:

• Use the dlstat command.

• Use the dlstat command with the show-link subcommand.

• Use the dlstat command with the show-aggr subcommand.

Local Home Directory Might Not Be Mounted (7082515)

A local home directory might not be mounted properly in environments where the Network Information Service (NIS) provides a map called auto.home instead of auto_home. In this case, automounter does not access /etc/auto_home on the local system.

Workaround: Choose one of the following workarounds:

• Create a symbolic link from the /etc/auto_home file to the /etc/auto.home file.

• In the /etc/auto_master file, move the +auto_master line to the end of the file.

datalink-management Service Times Out on the First Boot After Adding a Virtual Switch to the Control Domain (7087781)

The svc:/network/datalink-management:default service times out after adding a logical domain virtual switch device to the control domain and performing the first reboot. This time out causes the system to enter the system maintenance mode. The following error message is displayed:

svc:/network/datalink-management:default: 
Method or service exit timed out.  Killing contract 7.

network/datalink-management:default timed out: 
transitioned to maintenance (see 'svcs -xv' for details)

Requesting System Maintenance Mode
(See /lib/svc/share/README for more information.)
Console login service(s) cannot run

Enter user name for system maintenance (control-d to bypass):

Workaround: Perform a reconfiguration reboot instead of a normal reboot after you add the logical domain virtual switch.

# reboot -- -r

If the system is already in the system maintenance mode, log in as a superuser and type the following commands to restart the boot process:

# svcadm clear datalink-management
# exit

ipadm Command (7103136)

In this Oracle Solaris release, the ipadm(1M) command might not work as expected to configure networks. The ipadm command does not work when the DefaultFixed network configuration profile (NCP) is not enabled on the system.

Workaround: If you want to configure your network using the ipadm(1M) command, then you need to switch to the DefaultFixed NCP profile by using the following command:

# netadm enable -p ncp DefaultFixed

To determine the type of NCP profile enabled on your system, type the ipadm(1M) command.

# netadm list

If the DefaultFixed profile is enabled, then the command displays the following message:

netadm: DefaultFixed NCP is enabled; automatic network management is not available.
'netadm list' is only supported when automatic network management is active.

If the message is not displayed, then the system administrator should enable the profile using the following command:

# netadm enable -p ncp DefaultFixed

ipadm Command Does Not Work If the DefaultFixed Profile Is Not Enabled (7105597)

After updating the system from Oracle Solaris Express to Oracle Solaris 11, the system's host name is set to unknown. The system's host name is set to unknown when the system's hostname is retrieved from DHCP or the bootparams configuration data.

Workaround: Use one of the following workarounds:

• Reboot the system to set the host name correctly.

• If you cannot reboot the system, set the host name manually by typing the following commands:

  1. # svccfg -s svc:/system/identity:node setprop config/nodename = hostname

  2. # svccfg -s svc:/system/identity:node refresh

  3. # svcadm restart identity:node
