Would cqlsh describe command send query to cassandra server ?

[陈仕（shichen）-技术产品中心]

Hello, all.

I try to use `desc keyspaces` or desc table t`, and at the same time capture 
network packets at Cassandra side with tcpdump.
My tcpdump command is like this: tcpdump -i eth0 ip host 10.110.27.6 -X
But I found no string such as desc or keyspaces or table in the output.

So I wonder whether cqlsh fetch keyspace’s and table’s metadata just from local 
and not send query to server node ?

Thanks.
