General Administrative Information Pinging a Host STEP 3 Click Apply to set the configuration settings on the switch. 5 Pinging a Host Ping is a utility used to test if a remote host can be reached and to measure the round-trip time for packets sent from the switch to a destination device. Ping operates by sending Internet Control Message Protocol (ICMP) echo request packets to the target host and waiting for an ICMP response, sometimes called a pong. It measures the round-trip time and records any packet loss. To ping a host: STEP 1 Click Administration > Ping. The Ping page opens. STEP 2 Configure ping by entering the fields: • Host Definition-Select whether to specify hosts by their IP address or name. • IP Version-If the host is identified by its IP address, select either IPv4 or IPv6 to indicate that it will be entered in the selected format. • IPv6 Address Type-Select Link Local or Global as the type of IPv6 address to enter. - Link Local-The IPv6 address uniquely identifies hosts on a single network link. A link local address has a prefix of FE80, is not routable, and can be used for communication only on the local network. Only one link local address is supported. If a link local address exists on the interface, this entry replaces the address in the configuration. - Global-The IPv6 address is a global Unicast IPV6 type that is visible and reachable from other networks. • Link Local Interface-If the IPv6 address type is Link Local, select from where it is received. • Host IP Address/Name-Address or host name of the device to be pinged. Whether this is an IP address or host name depends on the Host Definition. Cisco Small Business 200 Series Smart Switch Administration Guide 50
