Subscribes the client to the specified channels.

Once the client enters the subscribed state it is not supposed to issue any
other commands, except for additional `SUBSCRIBE`, [`SSUBSCRIBE`]({{< relref "/commands/ssubscribe" >}}), [`PSUBSCRIBE`]({{< relref "/commands/psubscribe" >}}), [`UNSUBSCRIBE`]({{< relref "/commands/unsubscribe" >}}), [`SUNSUBSCRIBE`]({{< relref "/commands/sunsubscribe" >}}), 
[`PUNSUBSCRIBE`]({{< relref "/commands/punsubscribe" >}}), [`PING`]({{< relref "/commands/ping" >}}), [`RESET`]({{< relref "/commands/reset" >}}) and [`QUIT`]({{< relref "/commands/quit" >}}) commands.
However, if RESP3 is used (see [`HELLO`]({{< relref "/commands/hello" >}})) it is possible for a client to issue any commands while in subscribed state.

For more information, see [Pub/sub]({{< relref "/develop/pubsub" >}}).

## Behavior change history

*   `>= 6.2.0`: [`RESET`]({{< relref "/commands/reset" >}}) can be called to exit subscribed state.
