[f-nsp] help on trunk and lacp

[David Ball]

  When referring to Ethernet, 'trunking' generally refers to a port
which can carry multiple VLANs to an adjacent device (ie. not an
access port).  LACP stands for Link Aggregation Control Protocol, and
is a part of the IEEE specification for link aggregation (formerly
802.3ad, now 802.1AX-2008) whereby multiple physical ports/interfaces
(generally of the same speed) can be bundled together to form a link
whose bandwidth roughly equals the sum of the individual port speeds,
providing for (typically not 50/50) load sharing of the individual
links at layer 2.
  You can typically do 'trunking' across an aggregated link (LACP) bundle.
