If you attempt to ping a host in a different IP subnetwork, you must define a static route to the network or configure a router to route between those subnets. The ping command is configurable from normal executive and privileged executive mode. In normal executive mode, the ping command supports the -s parameter, which allows you to specify the packet size and packet count. In privileged executive mode, the ping command allows you to specify the packet size, packet count, and the wait time. 19-8 Software Configuration Guide-Catalyst 4000 Family, Catalyst 2948G, Catalyst 2980G, Releases 6.3 and 6.4 78-12647-02
