real

Use the real command to identify a real server that is a member of the server farm and to enter real server configuration submode. From here, you can configure the real server attributes. Use the no form of this command to remove the real server from the SLB configuration.

Syntax Description

ip-address

IP address of the real server.

Defaults

This command has no default setting.

Command Modes

Global configuration mode.

Examples

This example shows how to enter real server configuration submode:

Router-config# real 1.2.3.4
Router(config-if)#
 

This example shows how to remove a real server from the SLB configuration:

Router-config# no real 1.2.3.4
Router(config-if)#

reassign

Use the reassign command to define the number of consecutive number of SYNs for a new connection that will go unanswered before the connection is attempted to a different real server. Use the no form of this command to change the maximum number of connections to the default value.

Syntax Description

threshold

Number of unanswered TCP SYNs that will be directed to a real server before the connection is reassigned to a different real server; valid values are from 1 to 4.

Defaults

The default threshold is 3.

Command Modes

Real server configuration submode.

Usage Guidelines

If you do not specify the threshold, the default value of the reassignment threshold is used.

Examples

This example shows how to define the reassignment threshold:

Router(config-if)# reassign 4
Router(config-if)#
 

This example shows how to revert to the default value:

Router(config-if)# no reassign
Router(config-if)#

remote command

Use the remote command command to execute a switch command directly on the RP without having to log into the switch first.

Syntax Description

command

Command to be executed.

Defaults

This command has no default setting.

Command Modes

Privileged EXEC mode.

Usage Guidelines

This command does not support command completion for the command to execute remotely, but you can use shortened forms of the command (for example, entering sh for show).

Examples

This example shows how to execute the switch command from the RP:

Router# remote command show calendar
 
Switch-sp#
13:55:01 Pacific Mon Dec 6 1999
Router#                               

remote login

Syntax Description

This command has no keywords or arguments.

Defaults

This command has no default setting.

Command Modes

Privileged EXEC mode.

Usage Guidelines

When you execute the remote login command, the prompt changes to Switch-sp#.

Examples

This example shows how to perform a remote login to the switch console:

Console (enable)# remote login
Switch-sp#

retry

Use the retry command to define the amount of time that must elapse before a connection is attempted to a failed server. Use the no form of this command to change the connection reassignment threshold and client threshold to the default values.

Syntax Description

retry-value

Amount of time, in seconds, that must elapse after the detection of a server failure before a new connection is attempted to the server; valid values are from 1 to 3600.

Defaults

The default retry timer is 60.

Command Modes

Real server configuration submode.

Examples

This example shows how to define the retry timer:

Router(config-if)# retry 145
