flow-label

Use this command to to enable flow-label transmit, receive or both for the MPLS layer-2 virtual circuit and mpls vpls on dynamic and static VPWS and VPLS.

Use no command to disable flow-label transmit, receive or both for the MPLS layer-2 virtual circuit and mpls vpls on dynamic and static VPWS and VPLS.

For signaling flow-label capability in an RFC-compliant (RFC6391/8077) way using "The PWid FEC Element " = 0x80 when all Interface Parameter Sub-TLV is part of PWid FEC Element to support interop with other vendors, then interface-param-tlv can be used.

Command Syntax

Copy

flow-label (both|receive|transmit)(static|interface-param-tlv|)
no flow-label(static|interface-param-tlv|)

Parameters

both

flow label direction both (transmit and receive)

receive

flow label direction receive

transmit

flow label direction transmit

static

flow-label static

interface-param-tlv

ldp specific interface parameter tlv

Command Mode

config-pseudowire mode and config-vpls mode

Applicability

This command was introduced in OcNOS version 6.0.0 and added parameter interface-param-tlv in OcNOS version 6.3.0 to support interop with other vendors.

Example

For the config-pseudowire mode:

Copy

# configure terminal
(config)#mpls l2-circuit vc1111 1111 7.7.7.7
(config-pseudowire)#flow-label transmit
 
# configure terminal
(config)#mpls l2-circuit vc1111 1111 7.7.7.7
(config-pseudowire)#no flow-label

For the config-vpls mode:

Copy

# configure terminal
(config)#mpls vpls test 100
(config-vpls)# flow-label both interface-param-tlv 
# configure terminal
(config)#mpls vpls test 100
(config-vpls)# no flow-label

For the static configuration:

Copy

# configure terminal
(config)#mpls l2-circuit vc1111 1111 7.7.7.7
(config-pseudowire)#flow-label transmit static

For the config-vpls mode:

Copy

# configure terminal
(config)#mpls vpls test 100
(config-vpls)# flow-label both static
 
# configure terminal
(config)#mpls vpls test 100
(config-vpls)# no flow-label static

For the un-configuration of the static flow label:

For the config-pseudowire mode:

Copy

# configure terminal
(config)#mpls l2-circuit vc1111 1111 7.7.7.7
(config-pseudowire)#no flow-label static
