Huawei quidway s7700 - Configuring Dynamic BFD for PW

Example
Run the display bfd configuration pw interface interface-type interface-number
[ secondary ] [ verbose ] command, and you can view the discriminators of the BFD session,
the type of the PW that is bound to the BFD session, and the type of the BFD session. For
example:
<Quidway> display bfd configuration pw interface vlanif 10 verbose
--------------------------------------------------------------------------------
BFD Session Configuration Name : 1to2
--------------------------------------------------------------------------------
Local Discriminator : 12 Remote Discriminator : 21
BFD Bind Type : PW(Master)

Run the display bfd session pw interface interface-type interface-number [ secondary]
[ verbose ] command, and you can view the status of the BFD session, discriminators of the
BFD session, the type of the PW that is bound to the BFD session, and the type of the BFD
session. For example:
<PE1> display bfd session pw interface vlanif 10 verbose
