ObjectiveAfter completing this lab, you should be able to enable and disableswitch trunking on Bseries switches!

"e#uirementsBefore beginning this lab, it is assumed that$

%ou have completed the previous labs

The switches have interswitch link &'(L) connectivity on ports *7

+orts *7 are disabled

-! 2rom the (witch Admin window of 3eb Tools, select the +orts tab!0otice that the 1nable Trunking column has disabled trunking forevery port!

4! 'ssue a licenseshowto ensure that a trunking license is installed on

each of your switches!

0ote'f the trunking license is not loaded on one of your switches, re#uestthe license from your instructor!

*! 1nable ports *7 for each switch!

0oteThe Bseries *54- fabric switches have four port groups$ ports 67,ports .8, ports .-4, and ports -*4.! The '(Ls for a trunk groupmust reside in the same port group!

-! The trunkDebugcommand is used to determine why two switch

ports do not form a trunk group! This command is generally used toperform diagnostics when attempting to get trunking to run! 1;ecutethe command trunkDebug 0,4 from a Telnet session and
