Beware, there is an inconsistency in naming here ... many manufacturers
speak of combining multiple physical links to one logical link by
calling it "trunking". In Cisco names, a trunk is just a Multi-VLAN
capable port (by default, all available VLANs of a switch, though this
can be limited to certain VLANs of course). Some manufacturers may also
call it (channel) bonding ... So any time you hear anybody talk of
trunks, make sure you're all on the same grounds as far as the meaning goes.
Cisco calls this EtherChannels, or in Configuration terms,
Port-Channels. By configuring a channel group on multiple interfaces,
you combine their bandwidths, e.g.:

interface GigabitEthernet6/1
 channel-protocol lacp
 channel-group 1 mode active

interface GigabitEthernet7/1
  channel-protocol lacp
 channel-group 1 mode active

You then configure the logical channel as a separate interface, e.g. in
this case interface Port-channel1 ...
