Syntax

content_copy zoom_out_map
show services softwire flows
(<interface interface-name> <service-set service-set-name>|
count <interface interface-name> <service-set service-set-name>|
ds-lite <B4 b4-address> <AFTR aftr-address>|
v6rd <initiator initiator-ip-address><concentrator concentrator-ip-address>)

Description

Display statistics information about the softwire flows.

Note:

Starting with Junos OS Release 14.1R4, the IPv6 prefix length associated with a subscriber’s basic broadband bridging device that is subject to a limited number of sessions (dslite-ipv6-prefix-length attribute) is taken into account while the session count is calculated and displayed in the output of the show services softwire flows command. Until Junos OS Release 14.1R3, only IPv4 flows were counted and IPv6 flows were not considered for the statistics about softwire flows

Options

interface interface-name

(Optional) Display statistics information about the specified interface only.

service-set service-set-name

(Optional) Display statistics information about the specified service set only.

count <interface interface-name> <service-set service-set-name>|

(Optional) Display flow count information only, with optional filtering by interface and service set.

ds-lite <B4 b4-address> <AFTR aftr-address>|

(Optional) Display DS-Lite flow information, with optional filtering by B4 (softwire initiator) and AFTR (softwire concentrator).

v6rd <initiator initiator-ip-address><concentrator concentrator-ip-address>)

(Optional) Display v6rd flow information, with optional filtering by the softwire initiator and softwire concentrator.

Output Fields

Table 1 lists the output fields for the show services softwire flows command. Output fields are listed in the approximate order in which they appear.

Table 1: show services softwire flows Output Fields

Field Name

Field Description

Interface

Name of the interface.

Service set

Name of the service set.

Flow

Description of flow, including protocol input and output interface addresses.

State

Flow state. Value is:

  • Forward

Dir

Flow direction. Values are:

  • I—inbound

  • O—outbound

Frm count

Number of frames transferred.

NAT dest

NAT translation of the decapsulated address.

Softwire

For outbound flows, the address of the local softwire initiator (B4 for DS-Lite) is shown first, followed by the address of the softwire concentrator (AFTR for DS-Lite). For inbound flows, the address of the software concentrator is shown first, followed by the address of the softwire initiator.
