+In books, articles and documentation about AMQP 0.9.1 you may come around discussions of _consumer tags_. Consumer tag in AMQP
+parlance is an identifier for subscription: most often, it is used to unsubscribe from messages (more on that later in this chapter).
+If you need to obtain consumer tag of a queue that is subscribed to receive messages, use {AMQP::Queue#consumer_tag}.

 h2. Unsubscribing from messages

+Sometimes it is necessary to unsubscribe from messages without deleting a queue. To do that, use {AMQP::Queue#unsubscribe} method:
+
+<pre>
+<code>
+#!/usr/bin/env ruby
+# encoding: utf-8
+
+require "rubygems"
+require "amqp"
+
+AMQP.start("amqp://guest:[e-mail]:5672/") do |connection, open_ok|

+    exchange = channel.fanout("amq.fanout")

+      queue.bind(exchange).subscribe do |headers, payload|
+        puts "Received a new message"
+      end

+        queue.unsubscribe
+        puts "Unsubscribed. Shutting down..."

+
+By default {AMQP::Queue#unsubscribe} uses :noack option to inform broker that there is no need to send a
+confirmation. In other words, it does not expect you to pass in a callback, because consumer tag and registered
+callbacks are cleared immediately.
