DESCRIPTION

The ilbadm command manipulates or displays information about

Integrated Load Balancer (ILB) rules using the subcommands described below. Rule names are case insensitive, but case is preserved as it

is entered. Rule names are limited in length to 19 charac-

ters. Server names cannot exceed 14 characters.

All parseable output (invoked with the -p option) requires

that the fields to be printed or displayed be specified with

the -o option. Fields will be displayed in the same order

they are encountered on the command line. Multiple fields are separated by the colon (:) character. If a colon or backslash (\) occurs in the displayed string itself, it will be preceeded by a backslash. No headers will be displayed for parseable output. Server IDs are generated by the system when a server is

added, using either the create-servergroup or the add-server

subcommands.

SunOS 5.11 Last change: 30 Jul 2010 2

System Administration Commands ilbadm(1M)

Server IDs are guaranteed to be unique within the server group. A rule can be attached to only one server group, with the result that serverIDs are unique for rules as well. Note that since more than one rule can attach to the same server group, the server ID alone is not sufficient to indicate a rule. To be able to distinguish server IDs from hostnames, server

IDs are prefixed with a leading underscore (_).

As noted below, the server group and heathcheck entities

must be defined before they can be used in the create-rule

subcommand.

SUB-COMMANDS

Following are the ilbadm subcommands, along with their

related options and operands. Note that subcommands have a

normal and a short form; for example, create-rule and

create-rl, saving you from having to type a few additional

characters.

create-rule|create-rl [-e] [-p] -i incoming -m

method_attributes -o outgoing_spec [-h healthcheck] [-t

timers] name

Creates a rule name with a set of specified characteris-

tics. incoming and method_attributes are both specified

as a set of key=value pairs. If name already exists, the command will fail. If a given tuple (virtual IP address, port(s), and protocol) matches another rule,

the command will also fail. create-rule has the follow-

ing options that control the overall effect of the com-

mand:

-e Enable the create-rule function. The default is

that create-rule is disabled.

-p Create the rule as persistent (sticky). The

default is that the rule exists only for the current session.

Keys and values are introduced by one-letter identif-

iers. These identifiers and their related keys and acceptable values are as follows.

-i

Introduces the matching criteria for incoming pack-

ets.

SunOS 5.11 Last change: 30 Jul 2010 3

System Administration Commands ilbadm(1M)

vip (Virtual) destination IP address

port[-port]

Port number or name, for example, telnet or dns. A port can be specified by port number or symbolic name (as in /etc/services). Port number ranges are also supported. protocol TCP (the default) or UDP (see /etc/services).

-m

Specifies the keys describing how to handle a packet. lbalg The default is roundrobin, or its short form,

rr. Other alternatives are: hash-ip (short form:

hip), hash-ip-port (short form: hipp), hash-ip-

vip (short form: hipv). type Refers to topology of network. Can be DSR (or

dsr or d), NAT (or n or nat), HALF-NAT (or h or

half-nat).

proxy-src

Required for full NAT only. Specifies the IP address range to use as the proxy source address range. The range is limited to ten IP addresses. pmask Optional. Has an alias of: stickiness. Specifies that this rule is to be persistent. The argument is a prefix length in CIDR notation; that is,

0-32 for IPv4 and 0-128 for IPv6. Use the -p

SunOS 5.11 Last change: 30 Jul 2010 4

System Administration Commands ilbadm(1M)

option to specify this keyword.

-o

Specifies destination(s) for packets that match the

criteria specified by the -i "clause". This identif-

ier has one well-known argument:

servergroup Specify a single server group as tar-

get. The server group must already have been created.

-h

The health check option has two arguments:

hc-name

Specifies the name of a predefined health check method

hc-port

Specifies the port(s) for the HC test program to check. The value can be keywords ALL or ANY, or a specific port number within the port range of the server group.

-t

Specifies customized timers, in seconds. A value of

0 means to use the system default value. The follow-

ing are valid modifiers for -t:

conn-drain

If a server's type is NAT or HALF-TYPE, conn-

drain is the timeout after which the server's connection state is deleted following the server's removal from a rule. This deletion occurs even if the server is not idle. The default for TCP is that the connection state

remains stable until the connection is grace-

fully shutdown. The default for UDP is that the

SunOS 5.11 Last change: 30 Jul 2010 5

System Administration Commands ilbadm(1M)

connection state remains stable until the con-

nection has been idle for the period nat-

timeout.

nat-timeout

Applies only to NAT and half-NAT type connec-

tions. If such a connection is idle for the

nat-timeout period, the connection state will be

removed. The default is 120 for TCP and 60 UDP.

persist-timeout

When persistent mapping is enabled, if a

numeric-only mapping has not been used for

persist-timeout seconds, the mapping will be

removed. The default is 60. Note that server group and health check must be defined

before they can be used in create-rule.

delete-rule|delete-rl -a name[...]

Remove all information pertaining to rule name. If name

does not exist, command will fail. delete-rule has one

option:

-a

Delete all rules. (name is ignored.)

enable-rule|enable-rl name[...]

Enables a named rule, or all rules, if no name is speci-

fied). Enabling rules that are already enabled has no effect.

disable-rule|disable-rl name[...]

Disables a named rule, or all rules, if no name is specified. Disabling rules that are already disabled has no effect.

-d] [[-i] -r rulename | -s servername] [interval [count]]

Displays statistics, the output of which is subject to the use of the options described below. The syntax and semantics of this subcommand are modeled on vmstat(1M).

-t

Prepend a timestamp with every sample.

-d

Display the delta over entire interval. The default

is changes per second. Cannot be used with the -a

option.

-A

Display absolute numbers. That is, numbers since module initialization, rule creation, and server

addition. Cannot be used with the -d option.

-r rulename

Display statistics only for the specified rulename.

In combination with the -i option, display a line

for each server.

-s servername

Display statistics only for server. In combination

with the -i option, display a line for each rule.

source port was available. Note that when a question mark (?) is displayed as a column entry, it indicates that the proper value cannot be determined, most often because a rule or server was added or deleted.

SunOS 5.11 Last change: 30 Jul 2010 8

System Administration Commands ilbadm(1M)

Note that headers are displayed once for each ten sam-

ples. The timestamp format follows the date(1) format for the C locale. Neither the addition nor removal of a rule is detected.

show-rule|show-rl [-d|-e] [-f| [-p] -o field[,...]]

[name...] Displays characteristics of the specified rules, or all,

if no rule is specified. The subcommand has the follow-

ing options:

-d

Display only disabled rules.

-e

Display only enabled rules.

-f

Display a full list.

-o field[,...]

Display output for field(s). Cannot be used with -f

option.

-p

System Administration Commands ilbadm(1M)

positions of elements in consecutive runs of this com-

mand. For example, executing show-nat 10 twice is not

guaranteed to display the same ten items twice, espe-

cially on a busy system. Display format: T: IP1 > IP2 >>> IP3 > IP4 These items are described as follows: T The transport protocol used in this entry. IP1 The client's IP address and port. IP2 The VIP and port. IP3 If half NAT mode, the client's IP address and port. If full NAT mode, the NAT'ed client's IP address and port. IP4 The backend server's IP address and port.

show-persist|show-pt count

Displays persistence table information. If count is specified, displays count entries from the table. If no count is specified, displays the entire persistence table.

No assumptions should be made about the relative posi-

tions of elements in consecutive runs of this command.

For example, executing show-persist 10 twice is not

guaranteed to display the same ten items twice, espe-

cially on a busy system. Display format:

R: IP1 --> IP2

These items are described as follows: R

SunOS 5.11 Last change: 30 Jul 2010 10

System Administration Commands ilbadm(1M)

The rule this persistence entry is tied to. IP1 The client's IP address and port. IP2 The backend server's IP address.

export-config|export-cf [filename]

Exports the current configuration in a format suitable

for re-import using ilbadm import. If no filename is

specified, the subcommand writes to stdout.

import-config|import-cf [-p] [filename]

Reads configuration contents of a file. By default, this overrides any existing configuration. If no filename is

specified, the subcommand reads from stdin. This subcom-

mand has the following option:

-p

Preserve existing configuration and do incremental import.

create-servergroup|create-sg [-s

server=hostspec[:portspec...]] groupname Creates a server group. Additional servers can be added

later using the add-server subcommand. Server groups are

the only entity that can be used during rule creation to

indicate back-end servers. If the specified server group

is associated with one or more rules, the server is

enabled when it is added. This subcommand has the fol-

lowing option and operands:

-s server=hostspec[:portspec...]

Specifies a list of servers to be added to the server group. hostspec is a hostname or IP address. IPv6 addresses

System Administration Commands ilbadm(1M)

must be enclosed in brackets ([]) to distinguish them from ":portspec" portspec is a service name or port number. If the port number is not specified, a number in the range

1-65535 is used.

disable-server|disable-srv server

Disable one or more server(s). That is, tell the kernel

not to forward traffic to this server. disable-server

applies to all rules that are attached to the server group this server is part of. server is a server ID.

enable-server|enable-srv server...

Reenables disabled servers.

show-server|show-srv [[-p] -o field[,field...]]

[rulename...] Displays servers associated with named rules, or all servers if no rulename is specified. The subcommand has the following options.

option.

delete-servergroup|delete-sg groupname

Deletes a server group.

show-servergroup|show-sg [[-p] -o field[,...]] [name]

Lists a server group, or all server groups, if no name is specified. The subcommand has the following options:

SunOS 5.11 Last change: 30 Jul 2010 12

System Administration Commands ilbadm(1M)

-o field[,...]

Display output for field(s).

-p

Display parsable output in the format described in

"Description". Requires the -o option.

add-server|add-srv -s server=value[, value...] servergroup

Add specified server(s) to servergroup. See description

of create-servergroup for definition of value.

-s

See create-servergroup.

Performing an add-server to a server group immediately

after performing a remove-server on that server group

might fail because of incomplete connection draining.

Refer to the description of the remove-server subcommand

for instructions on how to avoid this failure.

remove-server|remove-srv -s server=value[, value...] server-

group Remove specified server(s) from servergroup.

-s

One or more of a server ID.

If a server is being used by a NAT/half-NAT rule, it is

recommended that the server be disabled (using disable-

server) before removal. By disabling a server, the

server enters the connection-draining state. After all

of the connections are drained, the server can then be

removed by remove-server. If the conn-drain timeout

value is set, the connection-draining state will be fin-

ished upon conclusion of the timeout period. Note that

the default conn-drain timeout is 0, meaning it will

keep waiting until a connection is gracefully shut down.

create-healthcheck|create-hc [-n] -h hc-test=value,hc-

timeout=value, hc-count=num_value,hc-interval=value hcname

SunOS 5.11 Last change: 30 Jul 2010 13

System Administration Commands ilbadm(1M)

Sets up a health check object for rules to use. All servers associated with a rule are checked using the same test. A health check event of a server consists of

one to hc-count number of hc-test executions. If an hc-

test's result shows a server to be unresponsive, further

hc-test checks are made, up to hc-count invocations,

before a server is considered to be down.

-h

The hc-test is performed hc-count times until it

succeeds or hc-timeout has expired. For a given

rule, all servers are checked using the same test. The tests are as follows:

hc-test

PING, TCP, external method (script or binary). An external method should be specified with a full path name.

hc-timeout

Threshold at which a test is considered failed

following interim failures of hc-test. If you

kill an hc-test test, the result is considered a

failure. The default value is five seconds.

hc-count

Maximum number of attempts to run hc-test before

marking a server as down. The default value is three iterations.

hc-interval

Interval between invocations of hc-test. This

value must be greater than hc-timeout times hc-

count. The default value is 30 seconds. The following arguments are passed to external methods:

VIP (literal IPv4 or IPv6 address).

SunOS 5.11 Last change: 30 Jul 2010 14

System Administration Commands ilbadm(1M)

Server IP (literal IPv4 or IPv6 address).

Protocol (UDP, TCP as a string).

The load balance mode, DSR, NAT, HALF_NAT.

Numeric port.

Maximum time (in seconds) the method should wait before returning failure. If the method runs for

longer, it can be killed, and the test con-

sidered failed.

External methods should return 0 (or the round-trip

time to the back end server, in microseconds) for

success and -1 if the server is considered down.

Before higher layer health check(s), TCP, UDP, and

external tests start, a default ping test is per-

formed first. The higher layer test will not be per-

formed if ping fails. You can turn off the default ping check for these high layer health checks by

through use of -n.

-n

Disable default ping test for high layer health check tests.

delete-healthcheck|delete-hc hcname...

Delete the named health check object(s) (hcname). If the given health check object is associated with enabled rule(s), deletion of the object will fail.

SunOS 5.11 Last change: 30 Jul 2010 15

System Administration Commands ilbadm(1M)

show-healthcheck|show-hc [hcname...]

List the health check information for the specified health check (hcname). If no health check is specified, list information for all existing health checks.

show-hc-result|show-hc-res [rule-name]

List the health check result for the servers that are

associated with rule-name. If rule-name is not given,

the health check results for all servers are displayed.

EXAMPLES

Example 1 Configuring NAT Mode The following commands create a rule with health check and timers set (port range shifting and session persistence).

# ilbadm create-healthcheck -h hc-test=tcp,hc-timeout=2,hc-count=3, \

hc-interval=10 hc1

# ilbadm create-servergroup -s \

server=60.0.0.10:6000-6009,60.0.0.11:7000-7009 sg1

# ilbadm create-rule -e -i vip=81.0.0.10,port=5000-5009,protocol=tcp \

-m lbalg=rr,type=NAT,proxy-src=60.0.0.101-60.0.0.104, \

pmask=24 \

-h hc-name=hc1 \

-t conn-drain=180,nat-timeout=180,persist-timeout=180 \

-o servergroup=sg1 rule1

The following command creates a rule with the default timer values and without health check.

# ilbadm create-servergroup -s server=60.0.0.10 sg1

# lbadm create-rule -e -i vip=81.0.0.10,port=5000 \

-m lbalg=rr,type=NAT,proxy-src=60.0.0.105 \
