To configure the type of response time reporter probe, use the type response time reporter configuration command. You must configure the probe's type before you can configure any of the other characteristics of the probe. Use the no form of this command to remove the type configuration for the probe.
type {echo | pathEcho} protocol type type-target| echo | Perform end-to-end response time reporter operations only. |
| pathEcho | Perform response time reporter operations by using a route discovery algorithm to find a path to the destination and echo each device on the path. |
| protocol type type-target | Protocol used by the probe. Type can be one of the following keywords (whether the keyword is available depends on the Cisco IOS software features installed on your router) followed by the required type parameter:
· ipIcmpEcho {ip-address | ip-host-name}--IP/ICMP Echo that requires a destination IP address or IP host name. · snaRUEcho sna-host-name--SNA's SSCP Native Echo that requires the host name defined for the SNA's Physical Unit connection to VTAM. · snaLU0EchoAppl sna-host-name [sna-application] [sna-mode]--An SNA LU Type 0 connection to Cisco's NSPECHO host application that requires the host name defined for the SNA's Physical Unit connection to VTAM. Optionally specify the host application name (the default is NSPECHO) and SNA mode to access the application. · snaLU2EchoAppl sna-host-name [sna-application] [sna-mode]--An SNA LU Type 2 connection to Cisco's NSPECHO host application that requires the host name defined for the SNA's Physical Unit connection to VTAM. Optionally specify the host application name (the default is NSPECHO), and SNA mode to access the application. |
To cause the response time reporter probe to check each response for corruption, use the verify-data response time reporter configuration command. Use the no form of this command to return to the default value.
