Chapter 57 Configuring Enhanced Object Tracking
Configuring Enhanced Object Tracking Features
Configuring a Cisco IP SLAs Monitoring Agent and Track Object
To configure network monitoring with Cisco IP SLAs, perform this task:
Configuring a Routing Policy and Default Route
To configure a routing policy for backup static routing by using object tracking, perform the following
task. For more details about the commands in the procedure, see:
http://www.cisco.com/en/US/docs/ios/dial/configuration/guide/dia_rel_stc_rtg_bckup.html
:
Step 1
configure terminal
Enters global configuration mode.
Step 2
ip sla operation-number
Begins configuring a Cisco IP SLAs operation and enter IP SLA
configuration mode.
Step 3
icmp-echo {destination-ip-address |
destination hostname [source- ipaddr
{ip-address | hostname
source-interface interface-id
]
Configures a Cisco IP SLAs end-to-end ICMP echo response time
operation and enter IP SLAs ICMP echo configuration mode.
Step 4
timeout milliseconds
Sets the amount of time for which the operation waits for a response
from its request packet.
Step 5
frequency seconds
Sets the rate at which the operation is sent into the network.
Step 6
threshold milliseconds
Sets the rising threshold (hysteresis) that generates a reaction event
and stores history information for the operation.
Step 7
exit
Exits IP SLAs ICMP echo configuration mode.
Step 8
ip sla schedule operation-number [life
{forever | seconds}] start-time time |
pending | now | after time
] [ageout
seconds
] [recurring]
Configures the scheduling parameters for a single IP SLAs operation.
Step 9{
track object-number ip sla
operation-number {state |
reachability
}
Tracks the state of a Cisco IOS IP SLAs operation and enter tracking
configuration mode.
Step 10
end
Returns to privileged EXEC mode.
Step 11
show track object-number
Displays tracking information to verify the configuration.
Step 12
copy running-config startup-config
(Optional) Saves your entries in the configuration file.
Step 1
configure terminal
Enters global configuration mode.
Step 2
access-list access-list-number
Defines an extended IP access list. Configure any optional
characteristics.
Step 3
route-map map-tag [permit | deny]
[
sequence-number]
Enters route-map configuration mode and define conditions for
redistributing routes from one routing protocol to another.
Step 4
match ip address {access-list number |
access-list name
}
Distributes any routes that have a destination network number address
that is permitted by a standard or extended access list or performs
policy routing on packets. You can enter multiple numbers or names.
Step 5
set ip next-hop dynamic dhcp
For DHCP networks only. Sets the next hop to the gateway that was
most recently learned by the DHCP client.
Step 6
set interface interface-id
For static routing networks only. Indicates where to send output
packets that pass a match clause of a route map for policy routing.
