Chapter 4: Configuring the High-Level Network

Mirroring virtual server state
Mirroring provides seamless recovery for current connections, persistence
information, SSL persistence, or sticky persistence when a BIG-IP fails.
When you use the mirroring feature, the standby unit maintains the same
state information as the active unit. Transactions such as FTP file transfers
continue as though uninterrupted.
Note
Mirroring slows BIG-IP performance and is primarily useful for long-lived
services like FTP and Telnet. Mirroring is not useful for short-lived
connections like HTTP.
Since mirroring is not intended to be used for all connections and
persistence, it must be specifically enabled for each virtual server.
To control mirroring for a virtual server
To control mirroring for a virtual server, use the bigpipe virtual mirror
command to enable or disable mirroring of persistence information, or
connections, or both. The syntax of the command is:
b virtual <virt addr>:<service> mirror [conn] enable|disable
To mirror connection information for the virtual server
Use the conn argument to mirror connection information for the virtual
server. To display the current mirroring setting for a virtual server, use the
following syntax:
b virtual <virt addr>:<service> mirror [conn] show
If you do not specify conn for connection information, the BIG-IP assumes
that you want to display that information.
Note
If you set up mirroring on a virtual server that supports FTP connections,
you need to mirror the control port virtual server, and the data port virtual
server.
Rules You can configure a virtual server to reference a rule. Rules are primarily used for selecting
pools during load balancing.
Software
acceleration
You can speed up packet flow for TCP connections when the packets are not fragmented.
