Configuring 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
switch. Beginning in privileged EXEC mode, follow these steps to configure the IP SLAs responder on
the target device (the operational target):
Command
Step 1
configure terminal
Step 2
ip sla responder {tcp-connect |
udp-echo} ipaddress ip-address port
port-number
Step 3
end
Step 4
show ip sla responder
Step 5
copy running-config startup-config
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, that has full IP SLAs support. Refer to the documentation for the source device for
configuration information.

Purpose
Enter global configuration mode.
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.
Return to privileged EXEC mode.
Verify the IP SLAs responder configuration on the device.
(Optional) Save your entries in the configuration file.
