Chapter 6 Configuring Redundant ACEs
Command
no ft-interface vlan vlan_id
Example:
host1/Admin(config-ft-peer) no
ft-interface vlan 200
Step 4
heartbeat {count number | interval
frequency }
Example:
host1/Admin(config-ft-peer) heartbeat
interval 500
no heartbeat {count number | interval
frequency }
Example:
host1/Admin(config-ft-peer) no heartbeat
interval 500
Step 5
query-interface vlan vlan-id
Example:
host1/Admin(config-ft-peer)#
query-interface vlan 400
no query-interface vlan vlan-id
Example:
host1/Admin(config-ft-peer)# no
query-interface vlan 400
Step 6
do copy running-config startup-config
Example:
host1/Admin(config-ft-peer)# do copy
running-config startup-config
OL-20823-01
Purpose
(Optional) Removes the FT VLAN from the peer configuration.
Configures the heartbeat interval and count.
The keywords and arguments are:
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. 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 can
occur. For example, in the default case, where the heartbeat
frequency is 300 ms and the heartbeat count is 10, if the
standby member does not receive a heartbeat packet from the
active member for 3000 ms (3 seconds), a switchover occurs.
interval frequency—Specifies the interval in milliseconds
•
(ms) between heartbeats. Enter an integer from 100 to 1000
ms. The default is 300 ms.
(Optional) Resets either the heartbeat count to the default of 10
or the heartbeat interval to the default of 100 ms.
Configures a query interface to allow the standby member to
determine whether the active member is down or if there is a
connectivity problem with the FT VLAN. A query interface helps
prevent two redundant contexts from becoming active at the same
time for the same FT group. Before triggering a switchover, the
ACE pings the active member to make sure that it is down.
Configuring a query interface allows you to assess the health of
the active member, but it increases switchover time.
The vlan_id argument specifies the identifier of an existing
VLAN. Enter an integer from 2 to 4094.
(Optional) Removes a query interface from the peer
configuration.
You cannot delete a query interface if it is associated with
Note
a peer. You must disassociate the interface from the peer
first, and then you can delete the interface.
(Optional) Copies the running configuration to the startup
configuration.
