I am using 6509 Switch installed with WS-X6748-SFP module. I used the command "show interface gigabitethernet 1/1 capablities". I am seeing a lot of stuffs in the output. One thing which interested me is "Ports-in-ASIC (Sub-port ASIC)" information. Find the attached command output file.
Ports-in-ASIC (Sub-port ASIC) : 1,3,5,7,9,11,13,15,17,19,21,23,25,27,29,31,33,35,37,39,41,43,45,47 (1,3,5,7,9,11,13,15,17,19,21,23)
Roughly i understood that One ASIC Port is shared with multiple Physical Ethernet ports.
I request your help to understand it more and provide me how it is oversubscribed. I checked in various documents, I am missing to get a good one
thnks in advance
