The SpeedTouch™ supports Service Level Agreement/QoS monitoring on a
continuous basis. An extended ping or trace route process can be started from the
SpeedTouch™ to another node in the worldwide IP network, to measure the QoS
(round-trip delay, packet loss, jitter, availability, routing stability, ..) to this other
node and all intermediate nodes. Interim and final results can be consulted on web,
CLI and via SNMP (RFC 2925).
Ping and traceroute are two very useful functions for managing networks. Ping is
typically used to determine if a path exists between two hosts while traceroute
shows an actual path
Ping is implemented using the Internet Control Message Protocol (ICMP) "ECHO"
facility. The SpeedTouch™ supports the DISMAN-PING-MIB as in RFC 2925 and up
to four concurrent ping tests.
The SLA ping process can be configured by executing the following CLI command:
=>:sla ping add test=internet addr=11.0.0.138
The following parameters are mandatory :
test
: this is just a name to identify the ping test
addr
: this is the peer IP address to which the ICMP echo requests will be
send
