G.2. Networking commands
	Appendix G. Command line reference

G.2.1. Subnets

show subnets
show subnet <integer>

You can list all current subnets, or details of a specific subnet. This shows the same information as the web status pages for subnets.

G.2.2. Ping and trace

ping <IPNameAddr> [table=<routetable>] [source=<IPAddr>]
     [gateway=<IPAddr>] [flow=<unsignedShort>]
     [count=<positiveInteger>] [ttl=<unsignedByte>]
     [size=<unsignedShort>] [xml=<boolean>]
traceroute <IPNameAddr> [table=<routetable>] [source=<IPAddr>]
           [gateway=<IPAddr>] [flow=<unsignedShort>]
	   [count=<positiveInteger>] [ttl=<unsignedByte>]
	   [size=<unsignedShort>] [xml=<boolean>]

This sends a series of ICMP echo requests (ping) to a specified destination and confirms a response is received and the round trip time. For the traceroute variant, the TTL/Hopcount is increased by one each time to show a series of response hops. There are a number of controls allowing you to fine tune what is sent. Obviously you should only send from a source address that will return to the FB6000 correctly. You can also ask for the results to be presented in an XML format.

Where possible, the reverse DNS name is shown next to replies, but there is (deliberately) no delay waiting for DNS responses, so you may find it useful to run a trace a second time as results from the first attempt will be cached.
