Control IPX Overhead Frequent update reduce the bandwidth for user traffic

Access list Command Overhead Step1: Set parameters for this access list test statement (which can be one of several statements) Router (config) # access-list acess-list-number { deny | permit } { test condition } Step2: Enable an interface to become part of the group that uses the specified access list Router (config-if) #ipx access - group Access-list-number / name in { in | out } ,[object Object],[object Object],[object Object]
