Note:
Note:
You cannot configure both DHCP Client and object tracking on the WAN
FastEthernet interface. You can however configure tracking on the DHCP client
default route. For more information on DHCP Client see

client on page 218.
Configuring RTR
For each remote device whose state you wish to monitor:
1. Enter
rtr
, followed by a number from
1
to
30
, to create the RTR. For example:
2. Use the
type
command to specify the remote device by address, and specify the probing
method to be employed by the RTR probe: ICMP Echo or TCP Connection.
If you specify a TCP Connection operation, specify also which port to probe in the remote
device. For example:
Or
3. Optionally, use the
frequency
command to specify the frequency at which RTR probes
are sent. If you do not configure this parameter, the default value of five seconds is used.
For example:
4. Optionally, use the
dscp
command to set the DSCP value in the IP header of the probe
packet, thus setting the packets’ priority. If you do not configure this parameter, the default
value of 48 is used. For example:
G350-001(config)# rtr 5
G350-001(config-rtr 5)#
G350-001(config-rtr 5)# type echo protocol ipIcmpEcho 10.0.0.1
G350-001(config-rtr icmp 5)#
G350-001(config-rtr 5)# type tcpConnect dest-ipaddr 147.42.11.1 dest-port
80
G350-001(config-rtr tcp 5)#
G350-001(config-rtr icmp 5)# frequency 2 seconds
Done!
G350-001(config-rtr icmp 5)# dscp 43
Done!
