Chapter 32 Configuring Cisco IOS IP SLAs Operations
Monitoring IP SLAs Operations
Configuring the IP SLAs Responder
The IP SLAs responder is available only on Cisco IOS software-based devices, including some Layer 2
switches that do not support full IP SLAs functionality, such as the Catalyst 2960 or the Cisco ME 2400
or IE 3000 switch running the LAN base image. Beginning in privileged EXEC mode, follow these steps
to configure the IP SLAs responder on the target device (the operational target):
To disable the IP SLAs responder, enter the no ip sla responder global configuration command. This
example shows how to configure the device as a responder for the UDP jitter IP SLAs operation in the
next procedure:
Switch(config)# ip sla responder udp-echo 172.29.139.134 5000
Note For the IP SLAs responder to function, you must also configure a source device, such as a Catalyst 3750
or Catalyst 3560 switch running the IP services image, that has full IP SLAs support. Refer to the
documentation for the source device for configuration information.
Monitoring IP SLAs Operations
Use the User EXEC or Privileged EXEC commands in Table 32-1 to display IP SLAs operations
configuration.
Command Purpose
Step 1
configure terminal Enter global configuration mode.
Step 2
ip sla responder {tcp-connect |
udp-echo} ipaddress ip-address port
port-number
Configure the switch as an IP SLAs responder.
The optional keywords have these meanings:
• tcp-connect—Enable the responder for TCP connect operations.
• udp-echo—Enable the responder for User Datagram Protocol (UDP)
echo or jitter operations.
• ipaddress ip-address—Enter the destination IP address.
• port port-number—Enter the destination port number.
Note The IP address and port number must match those configured on
the source device for the IP SLAs operation.
Step 3
end Return to privileged EXEC mode.
Step 4
show ip sla responder Verify the IP SLAs responder configuration on the device.
Step 5
copy running-config startup-config (Optional) Save your entries in the configuration file.
