FT Peer Configuration Mode Commands
Fault-tolerant (FT) peer configuration mode commands allow you to configure redundancy parameters for peer (standby) ACEs. Each FT group in a redundant configuration consists of two ACE ACEs: a local active ACE and a remote standby ACE or peer.
To configure an FT peer and access FT peer configuration mode, use the ft peer command in configuration mode. The CLI prompt changes to (config-ft-peer). For information about the commands in FT peer configuration mode, see the following commands.
Use the no form of this command to remove an FT group from the configuration.
ft peer peer_id
no ft peer peer_id
Syntax Description
peer_id |
Unique identifier of the FT peer. Enter 1. |

Usage Guidelines
All commands in this mode require the Admin user role. For details about role-based access control (RBAC) and user roles, see the Virtualization Guide, Cisco ACE Application Control Engine.
Examples
To configure an FT peer and access FT peer configuration mode, enter:
host1/Admin(config)# ft peer 1
host1/Admin(config-ft-peer)#
To delete the FT peer configuration, enter:
host1/Admin(config)# no ft peer 1

(config-ft-peer) ft-interface vlan
To associate an existing fault-tolerant (FT) VLAN with a peer, use the ft-interface vlan command. Use the no form of this command to remove the FT VLAN from the peer configuration.
ft-interface vlan vlan_id
no ft-interface vlan vlan_id
Syntax Description
vlan_id |
Identifier of an existing VLAN. Enter an integer from 2 to 4094. |

Examples
To associate an existing FT VLAN with a peer, enter:
host1/Admin(config-ft-peer)# ft-interface vlan 200

(config) ft interface vlan
(config-ft-peer) heartbeat
To configure the heartbeat interval and count for verification timing between active and standby fault-tolerant (FT) peers, use the heartbeat command. Use the no form of this command to revert to the default heartbeat interval and count.
heartbeat {count number | interval frequency}
no heartbeat {count number | interval frequency}
Syntax Description
count number |
Specifies the number of heartbeat intervals that must transpire with no heartbeat packet received by the standby member before the standby member determines that the active member is not available. Enter an integer from 10 to 50. The default is 10 heartbeat intervals. |
interval frequency |
Specifies the time period between heartbeats in milliseconds (ms). Enter an integer from 100 to 1000 ms. The default is 300 ms. |

This command was introduced. |
Usage Guidelines
If the standby member of the FT group does not receive a heartbeat packet from the active member, a time period equal to count number times interval frequency must elapse before a switchover between the active and standby members can occur.
Examples
To set a heartbeat count of 20, enter:
host1/Admin(config-ft-peer)# heartbeat count 20
To set a heartbeat interval of 200 milliseconds, enter:
host1/Admin(config-ft-peer)# heartbeat interval 200
Related Commands
show ft
(config-ft-peer) query-interface
To configure an alternate interface to allow the standby member to determine whether the active member is down or whether there is a connectivity problem with the fault-tolerant (FT) VLAN, use the query-interface command. A query interface helps prevent two redundant contexts from becoming active at the same time for the same FT group. Use the no form of this command to remove the query interface from the peer configuration.
query-interface vlan vlan_id
no query-interface vlan vlan_id
Syntax Description
vlan vlan_id |
Specifies the identifier of an existing VLAN. Enter an integer from 2 to 4094. |

Usage Guidelines
Configuring a query interface allows you to assess the health of the active FT group member, but it increases failover time. You cannot delete a query interface if it is associated with a peer. You must dissociate the interface from the peer first, and then you can delete the query interface.
Examples
To configure a query interface, enter:
host1/Admin(config-ft-peer)# query-interface vlan 400
