Chapter 37 Configuring Cisco IOS IP SLAs Operations
Configuring IP SLAs Operations
Before configuring any IP SLAs application, you can use the show ip sla application privileged EXEC
command to verify that the operation type is supported on your software image. This is an example of
the output from the command:
Switch# show ip sla application

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 or a Cisco ME 3400 switch running the metro base image. Beginning in privileged EXEC mode,
follow these steps to configure the IP SLAs responder on the target device (the operational target):
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 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.
