radius-server deadtime

To configure the dead-time interval for all RADIUS servers used by a device, use the radius-server deadtime command. To revert to the default, use the no form of this command.

radius-server deadtime minutes

no radius-server deadtime minutes

Syntax Description

minutes

Number of minutes for the dead-time interval. The range is from 1 to 1440 minutes.


Defaults

0 minutes

Modification

4.0(4)SV1(1)

This command was introduced.


Usage Guidelines

The dead-time interval is the number of minutes before the device checks a RADIUS server that was previously unresponsive.

Note The default idle timer value is 0 minutes. When the idle time interval is 0 minutes, periodic RADIUS server monitoring is not performed.

Examples

This example shows how to configure the global dead-time interval for all RADIUS servers to perform periodic monitoring: 

n1000v# config t

n1000v(config)# radius-server deadtime 5

This example shows how to revert to the default for the global dead-time interval for all RADIUS servers and disable periodic server monitoring: 

n1000v# config t

n1000v(config)# no radius-server deadtime 5

Command History

Release
Modification

4.0(4)SV1(1)

This command was introduced.


Usage Guidelines

Use the rate-mode dedicated command to set the dedicated rate mode for the specified ports.

On a 32-port 10-Gigabit Ethernet module, each set of four ports can handle 10 gigabits per second (Gb/s) of bandwidth. You can use the rate-mode parameter to dedicate that bandwidth to the first port in the set of four ports or share the bandwidth across all four ports.

Note When you dedicate the bandwidth to one port, you must first administratively shut down the ports in the group, change the rate mode to dedicated, and then bring the dedicated port administratively up.

Table 1-1 identifies the ports that are grouped together to share each 10 Gb/s of bandwidth and which port in the group can be dedicated to utilize the entire bandwidth.

Table 1-1 Dedicated and Shared Ports

Ports Groups that Can Share Bandwidth
Ports that Can be Dedicated to Each 10-Gigabit Ethernet of Bandwidth

1, 3, 5, 7

2, 4, 6, 8

When you enter the rate-mode dedicated command, the full bandwidth of 10 Gb is dedicated to one port. When you dedicate the bandwidth, all subsequent commands for the port are for dedicated mode.

Examples

This example shows how to configure the dedicated rate mode for Ethernet ports 4/17, 4/19, 4/21, and 4/23: 

n1000v# config t 

n1000v(config)# interface ethernet 4/17, ethernet 4/19, ethernet 4/21, ethernet 4/23

n1000v(config-if)# shutdown

n1000v(config-if)# interface ethernet 4/17

n1000v(config-if)# rate-mode dedicated

n1000v(config-if)# no shutdown

n1000v(config-if)#
