D Commands

This chapter describes the Cisco Nexus 1010 commands that begin with the letter D.

deadtime

To configure the duration of time for which a nonreachable TACACS+ server is skipped, use the deadtime command. To revert to the default, use the no form of this command.

deadtime minutes

no deadtime minutes

Syntax Description

minutes

Number of minutes, from 0 to 1440, for the interval.

Defaults

0 minutes

Command Modes

TACACS+ server group configuration (config-tacacs+)
Global configuration (config)

Supported User Roles

network-admin

Command History

Release	Modification
4.0(4)SP1(1)	This command was introduced.

Usage Guidelines

Before you can configure it, you must enable TACACS+ using the tacacs+ enable command.

The dead time can be configured either globally and applied to all TACACS+ servers, or you can configure the dead time per server group.

If the dead time interval for a TACACS+ server group is greater than zero (0), that value takes precedence over the global dead time value.

Setting the dead time interval to 0 disables the timer.

When the dead time interval is 0 minutes, TACACS+ servers are not marked as dead even if they are not responding.

Examples

This example shows how to set a global dead time interval to 5 minutes for all TACACS+ servers and server groups:

switch# config t

switch(config)# tacacs-server deadtime 5

switch(config)# 

This example shows how to set the dead time interval to 5 minutes for a TACACS+ server group:

switch# config t

switch(config)# aaa group server tacacs+ TacServer

switch(config-tacacs+)# deadtime 5

This example shows how to revert to the dead time interval default:

switch# config t

switch(config)# feature tacacs+

switch(config)# aaa group server tacacs+ TacServer

switch(config-tacacs+)# no deadtime 5
