132 CHAPTER 6: IP SERVICES COMMANDS
Syntax — ping host [count num-packets ] [dnf] [flood]
[interval time] [size size] [source-ip ip-addr | vlan-name]
■ host — IP address, MAC address, hostname, alias, or user to ping.
■ count num-packets — Number of ping packets to send. You can
specify from 0 through 2,147,483,647. If you enter 0, MSS pings
continuously until you interrupt the command.
■ dnf — Enables the Do Not Fragment bit in the ping packet to prevent
the packet from being fragmented.
■ flood — Sends new ping packets as quickly as replies are received, or
100 times per second, whichever is greater.
Use the flood option sparingly. This option creates a lot of traffic and can
affect other traffic on the network.
■ interval time — Time interval between ping packets, in
milliseconds. You can specify from 100 through 10,000.
■ size size — Packet size, in bytes. You can specify from 56 through
65,507.
Because the WX switch adds header information, the ICMP packet size is
8 bytes larger than the size you specify.
■ source-ip ip-addr — IP address, in dotted decimal notation, to use
as the source IP address in the ping packets.
■ source-ip vlan-name — VLAN name to use as the ping source. MSS
uses the IP address configured on the VLAN as the source IP address in
the ping packets.
Defaults
■ count — 5.
■ dnf — Disabled.
■ interval — 100 (one tenth of a second)
■ size — 56.
Access — Enabled.
History — Introduced in MSS Version 3.0.
