B:This example shows how to create a DLMP aggregation. The aggregation has three underlying datalinks.

# dladm create-aggr -m haonly -l net0 -l net1 -l net2 aggr0

# dladm show-link

LINK CLASS MTU STATE BRIDGE OVER

net0 phys 1500 up -- ----

net1 phys 1500 up -- ----

net2 phys 1500 up -- ----

aggr0 aggr 1500 up -- net0, net1, net2

# dladm show-aggr

LINK MODE POLICY ADDRPOLICY LACPACTIVITY LACPTIMER

aggr0 haonly --

E:Check the status of the aggregation you just created.

# dladm show-aggr

The aggregation's state should be UP.

Note:

*A user can only assume roles that are assigned to the user's login account.

*After you have set up roles with default Solaris rights profiles, and assigned the roles to users, the roles can be used. A role can be assumed on the command line. In the Solaris Management Console, a role can also be used for administering the system locally and over the network.

*How to Assume a Role in a Terminal Window

The role must already be assigned to you. The name service must be updated with that information.

• In a terminal window, determine which roles you can assume.
• % roles

Comma-separated list of role names is displayed

• Use the su command to assume a role.
• % su -rolename
• Password:

$

The su - rolename command changes the shell to a profile shell for the role. A profile shell recognizes security attributes (authorizations, privileges, and set ID bits).

• Verify that you are now in a role.
• $ /usr/ucb/whoami

rolename

You can now perform role tasks in this terminal window.

*WAN boot

SPARC clients of AI installation over the network must support WAN boot.

To boot over the network, AI requires WAN boot support for SPARC clients. You can check whether your client Open Boot PROM (OBP) supports WAN boot by checking whether network-boot-arguments is a valid variable that can be set in the eeprom.

If the variable network-boot-arguments is displayed, or if the command returns the output network-boot-arguments: data not available, the OBP supports WAN boot and the client can be installed over the network.

*The following command shows how to check the client OBP for WAN boot support.

# eeprom | grep network-boot-arguments

network-boot-arguments: data not available

In this example, the output network-boot-arguments: data not available indicates that the client OBP supports WAN boot.

Tasks such as installing and updating IPS packages, setting publishers, and modifying images require more privilege.

TFTP Error or System Hangs After GATEWAY Message

The DHCP server provides an IP address and a location of the initial boot program as part of the DHCP response.

If the boot program does not exist, then the AI client boot cannot proceed. The following message is displayed:

*Booting a system using the none milestone can be very useful for debugging startup problems. There is no equivalent run level to the none milestone.

*If problems with starting services occur, sometimes a system will hang during the boot. This procedure shows how to troubleshoot this problem.

2.Boot without starting any services.

This command instructs the svc.startd daemon to temporarily disable all services and start sulogin on the console.

ok boot -m milestone=none

2.Log in to the system as root.

3.Enable all services.

# svcadm milestone all

4.Determine where the boot process is hanging.

When the boot process hangs, determine which services are not running by running svcs -a. Look for error messages in the log files in /var/svc/log.

• After fixing the problems, verify that all services have started.

Verify that all needed services are online.

# svcs -x

Verify that the console-login service dependencies are satisfied.

This command verifies that the login process on the console will run.

# svcs -l system/console-login:default

6.Continue the normal booting process.

Note:

*Immutable Zones provide read-only file system profiles for solaris non-global zones.

*A zone with a read-only zone root is called an Immutable Zone. A solaris Immutable Zone preserves the zone's configuration by implementing read-only root file systems for non-global zones. This zone extends the zones secure runtime boundary by adding additional restrictions to the runtime environment. Unless performed as specific maintenance operations, modifications to system binaries or system configurations are blocked.

Version5.1.37-0.1/4 is installed(see note 1 below) and this version can be updated (see note 2 below).

Note:

* 1The “i” in the I column indicates that these packages are installed in this image.

2An “f” in the F column indicates the package is frozen. If a package is frozen, you can only install or update to packages that match the frozen version.

*The pkg list command tells you whether a package is installed in the current image and whether an update is available. With no options or operands, this command lists all packages that are installed in the current image. To narrow your results, provide one or more package names. You can use wildcards in the package names. Package variants for an architecture or zone type that does not match this image are not listed.

B:Example:Creating a Policy Around a Mission-Critical Port

The command below creates a policy around inbound HTTPS traffic on an HTTPS server so that HTTPS obtains dedicated NIC hardware and kernel TCP/IP resources. The name specified, https-1, can be used later to modify or delete the policy.

# flowadm add-flow -l bge0 -a transport=TCP,local_port=443 https-1

# flowadm show-flow -l bge0

FLOW LINK IP ADDR PROTO PORT RPORT DSFLD

https1 bge0 -- tcp 443 -- --

Note:

*Flow Restrictions Per Zone

Within a zone, no two flows can have the same name. After adding a flow with the link specified, the link will not be required for display, modification, or deletion of the flow.

Incorrect:

Not A:Flow Properties

The following flow properties are supported. Note that the ability to set a given property to a given value depends on the driver and hardware.

maxbw

Sets the full duplex bandwidth for the flow. The bandwidth is specified as an integer with one of the scale suffixes(K, M, or G for Kbps, Mbps, and Gbps). If no units are specified, the input value will be read as Mbps. The default is no bandwidth limit.

priority

Sets the relative priority for the flow. The value can be given as one of the tokens high, medium, or low. The default is medium.

Not D:The following types of combinations of attributes are supported:

local_ip[/prefixlen]=address

remote_ip[/prefixlen]=address

transport={tcp|udp|sctp|icmp|icmpv6}

transport={tcp|udp|sctp},local_port=port

transport={tcp|udp|sctp},remote_port=port

dsfield=val[:dsfield_mask]

On a given link, the combinations above are mutually exclusive. An attempt to create flows of different combinations will fail.

Note:Flow Attributes

The flow operand that identify a flow in a flowadm command is a comma-separated list of one or more keyword, value pairs from the list below.

local_ip[/prefix_len]

remote_ip[/prefix_len]

transport={tcp|udp|sctp|icmp|icmpv6}

local_port

Identifies a service specified by the local port.

remote_port

Identifies a service specified by the remote port.

dsfield[:dsfield_mask]

NotE:

*flowstat

- report flow statistics

*The flowstat command reports run time statistics about user defined flows. flowadm show-flow provides the flow name information for this command.

*flowstat [-r | -t] [-i interval] [-l link] [flow]

This form of the command iteratively examines all flows and reports statistics. The output is sorted in descending order of flow utilization. If no flow is specified, the system displays statistics for all flows.

-r

Display receive-side statistics only. Includes bytes and packets received, drops, and so forth.

-t

Display transmit-side statistics only. Includes bytes and packets sent, drops, and so forth.

-i interval

Specify an interval in seconds at which statistics are refreshed. The default interval is one second.

-l link | flow]

Display statistics for all flows on the specified link or statistics for the specified flow.

No DHCP or Proxy DHCP Offers Were Received

If a DHCP server is not responding to an x86 client's request, you see the following messages:

Intel(R) Boot Agent PXE Base Code (PXE-2.1 build 0.86)

DHCP......... No DHCP or ProxyDHCP offers were received

PXE-MOF: Exiting Intel Boot Agent

The timeout message indicates that the client is sending a DHCP request and not getting a response. This issue is probably due to an error in the DHCP configuration. Check to see if your client is configured correctly in the DHCP server.
