FT Track Host Configuration Mode Commands
Fault-tolerant (FT) track host configuration mode commands allow you to configure tracking and failure detection for critical network gateways and hosts.
To create a process that tracks and detects failures for a gateway or host and accesses FT track host configuration mode, use the ft track host command in configuration mode. The CLI prompt changes to (config-ft-track-host). For information about the commands in FT track host configuration mode, see the following commands.
Use the no form of this command to delete a process that tracks and detects failures for a gateway or host.
ft track host name
no ft track host name
Syntax Description
name |
Unique identifier of the tracking process for a gateway or a host. Enter an unquoted text string with no spaces and a maximum of 64 alphanumeric characters. |

Usage Guidelines
The commands in this mode require the fault-tolerant feature in your user role. For details about role-based access control (RBAC) and user roles, see the Virtualization Guide, Cisco ACE Application Control Engine.
Examples
To create a process that tracks and detects failures for a gateway or host and accesses FT track host configuration mode, enter:
host1/Admin(config)# ft track host TRACK_GATEWAY1
host1/Admin(config-ft-track-host)#
To delete the process that tracks and detects failures for a gateway or host, enter:
host1/Admin(config)# no ft track host TRACK_GATEWAY1

(config-ft-track-host) peer priority
To assign a priority for multiple probes on the standby member of a fault-tolerant (FT) group, use the peer priority command. Use the no form of this command to reset the multiple-probe priority to the default value of 10 on the standby member.
peer priority number
no peer priority number
Syntax Description
number |
Priority of the probes configured for the gateway or host on the standby member. Enter a priority value as an integer from 0 to 255. The default is 0. Higher values indicate higher priorities. |

Usage Guidelines
The peer command keyword indicates the standby member of an FT group.
Assign a priority value to multiple probes based on the relative importance of the gateway or host that the probes are tracking. If all the probes go down, the ACE decrements the priority of the FT group on the standby member by the value of the number argument. If the priority of the FT group on the active member falls below the priority of the FT group on the standby member, a switchover occurs where the active member becomes the standby member and the standby member becomes the active member.
Examples
To assign a priority for multiple probes on the standby member of an FT group, enter:
host1/Admin(config-ft-track-host)# peer priority 50
To reset the priority of multiple probes on the standby member of an FT group to the default value of 0, enter:
host1/Admin(config-ft-track-host)# no peer priority 50
Related Commands
(config-ft-track-host) priority
(config-ft-track-host) peer probe
To associate an existing probe with a gateway or host for tracking by the standby member of a fault-tolerant (FT) group, use the peer probe command. Use the no form of this command to dissociate the tracking probe from the tracking process on the standby member.
peer probe name priority number
no peer probe name priority number
Syntax Description
name |
Identifier of an existing probe that you want to associate with a gateway or host for tracking. |
priority number |
(Optional) Specifies the priority of the probe. Enter an integer from 0 to 255. The default is 0. Higher values indicate higher priorities. |
