Each port eligible to transmit traffic on a Flex PW port, must be added to a pw-port-list.
config>service>system> PW port list# port ?
- no port <port-id> [<port-id>... (16 max)]
- port <port-id> [<port-id>... (16 max)]
Only hybrid ports (configure port port-id ethernet mode hybrid) can be members of a PW port list.
A port used by Flex PW port can be shared with any other Layer 2 or Layer 3 service. For example, a Layer 3 interface using a regular SAP can be associated with a VPRN service, while the underlying port is also used by a Flex PW port. Another regular SAP from the same port can be associated with a VPLS or Epipe service at the same time.
Follow these rules when populating a PW port list:
A port must be in hybrid mode before it is added to a PW port list.
Before a port is removed from or added to a PW port list, all PW ports must be dissociated from the corresponding Epipe services (the PW ports must be unconfigured). This implies that all PW SAPs be deleted.
Network interfaces (configured in Base routing context) can be configured only on ports that are in the PW port list.
A port mode (access, network, or hybrid) cannot be changed while the port is in the PW port list.
From this, an operator can consider adding all ports that are in hybrid mode to a PW port list from the beginning of the system configuration. This ensures that those ports can be used by Flex PW port at any later time, independently of their current use.
