-## Switched Port Analyzer (SPAN)
-Port mirroring is used on a network switch to send a copy of network packets seen on one switch port to a network monitoring connection on another switch port.
-Can be used by network engineers or administrators to measure performance, analyze and debug data or diagnose errors on a network.
-
-### RX traffic node
-There is one static node to mirror incoming packets.
-* span-input: Creates a copy of incoming buffer due to incoming buffers can be reused internally.
-
-Chaining: dpdk-input -> span-input ->
-* original buffer is sent to ethernet-input for processing
-* buffer copy is sent to interface-output
-
-### Configuration
-SPAN supports the following CLI configuration commands:
-
-#### Enable/Disable SPAN (CLI)
-	set interface span <if-name> [disable | destination <if-name>]
-
-<if-name>: mirrored interface name
-destination <if-name>: monitoring interface name
-disable: delete mirroring
-
-#### Enable/Disable SPAN (API)
-SPAN supports the following API configuration command:
-	sw_interface_span_enable_disable src GigabitEthernet0/8/0 dst GigabitEthernet0/9/0
-	sw_interface_span_enable_disable src_sw_if_index 1 dst_sw_if_index 2
-
-src/src_sw_if_index: mirrored interface name
-dst/dst_sw_if_index: monitoring interface name
-
-#### Remove SPAN entry (API)
-SPAN supports the following API configuration command:
-	sw_interface_span_enable_disable src_sw_if_index 1 dst_sw_if_index 2 disable
-
-src_sw_if_index: mirrored interface name
-dst_sw_if_index: monitoring interface name
-
-### Configuration example
-
-Mirror all packets on interface GigabitEthernet0/10/0 to interface GigabitEthernet0/11/0.
-
-Configure IPv4 addresses on mirrored interface:
-set interface ip address GigabitEthernet0/10/0 192.168.1.13/24
-set interface state GigabitEthernet0/10/0 up
-
-Configure IPv4 addresses on monitoring interface:
-set interface ip address GigabitEthernet0/11/0 192.168.2.13/24
-set interface state GigabitEthernet0/11/0 up
-
-Configure SPAN
-set span src GigabitEthernet0/10/0 dst GigabitEthernet0/11/0
-
-### Operational data
-
-Active SPAN mirroring CLI show command:
-    show interfaces span
-
-Active SPAN mirroring API dump command:
-    sw_interface_span_dump

+Switched Port Analyzer
+======================

+This is a memo intended to contain documentation of the VPP SPAN
+implementation. Everything that is not directly obvious should come
+here.
+
+Port mirroring is used on a network switch to send a copy of network
+packets seen on one switch port to a network monitoring connection on
+another switch port. Can be used by network engineers or administrators
+to measure performance, analyze and debug data or diagnose errors on a
+network.

+RX traffic node
+~~~~~~~~~~~~~~~
+
+There is one static node to mirror incoming packets. \* span-input:
+Creates a copy of incoming buffer due to incoming buffers can be reused
+internally.
+
+Chaining: dpdk-input -> span-input -> \* original buffer is sent to
