clone

Description

Causes the system to clone traffic to the specified pool, pool member, or vlan regardless of monitor status. (Pool member status may be determined by the use of the LB::status command. Failure to select a server because none are available may be prevented by using the active_members command to test the number of active members in the target pool before choosing it.) Any responses to cloned traffic from pool members will be ignored. “Clone” is meant to be used to allow traffic to be sent to devices such as IDS, Sniffers, etc and is not meant to try load balancing a single request to multiple systems at the same time.
Pool / member may be selected conditionally. If multiple conditions match, the last match will determine the pool/member to which this traffic is cloned.
Nexthop will be used to send cloned traffic to physical interface(s) mapped to the vlan. (the nexthop option is v13+ only)

Syntax

clone pool <pool_name>
clone pool <pool_name> [member <addr> [<port>]]
# Added in v13
clone pool <vlan>

clone pool <pool_name>

  • Specifies the pool to which you want to send the cloned traffic.

clone pool <pool_name> [member <addr> [<port>]]

  • Specifies a pool member to which you want to directly send the cloned traffic.

clone pool <vlan>

  • Specifies a vlan to which you want to send the cloned traffic.

Examples

# Clone traffic based on the requested HTTP URI
when HTTP_REQUEST {
  if { [HTTP::uri] starts_with "/clone_me" } {
    pool real_pool
    clone pool clone_pool
  } else {
    pool real_pool
  }
}


# Clone only traffic destined for one VS pool member
when LB_SELECTED {
  if { [IP::addr [LB::server addr] equals 10.1.1.1] } {
    clone pool member1_clone_pool
  }
}


# Clone traffic to a tap vlan
when CLIENT_ACCEPTED {
    clone nexthop tap_vlan
 }
