Object tracking
Issue 5 June 2008 323
●
Use the
success-retries
command to specify how many consecutive answered
probes change the state of an RTR from down to up. The default value is 5.
For example:
8. Exit the RTR type context, and activate the RTR with the
rtr-schedule
command.
Note:
Note:
To deactivate the RTR, use the
no rtr-schedule
command. For example:
Note:
Note:
Once an RTR’s probing method and remote device address is configured, you
cannot change them. If you exit the RTR type context and you want to modify the
configuration of the RTR, you can enter the RTR context using the
rtr
command
and specifying the RTR ID. From the RTR context, you can run the various
modification commands described in steps 3 to 7.
Configuring object tracking
To configure object tracking, you must first configure at least one simple object tracker, that is,
an object tracker that tracks a single RTR. If you wish, you can then configure a track list which
contains multiple simple object trackers and specifies how to calculate the overall state of the
list. Note that a track list is itself an object tracker. Therefore, you can configure track lists
containing object trackers which are either simple object trackers, or other track lists.
Configuring a simple object tracker
1. Use the
track id rtr
command to specify the RTR to be tracked. Enter a number from
1
to
50
as the unique ID for this object tracker. For example:
2. Use the
description
command to enter a description for the object tracker. For
example:
G350-001(config-rtr icmp 5)# wait-interval 2 seconds
Done!
G350-001(config-rtr icmp 5)# fail-retries 3
Done!
G350-001(config-rtr icmp 5)# success-retries 1
Done!
G350-001(config-rtr icmp 5)# exit
G350-001(config)# rtr-schedule 5 start-time now life forever
G250-001(config)# track 1 rtr 5
G250-001(config-track rtr 1)#
G250-001(config-track rtr 1)# description "track rtr-5"
Done!
