A2-400-QD-16-T1S Appliance - 100G ECM Scaling Modes - When activating the LAG profile 2x8 (2 portgroups/8 ports each), why is STC displaying 16 ports per portgroup?

A2-400-QD-16-T1S Appliance - 100G ECM Scaling Modes - When activating the LAG profile 2x8 (2 portgroups/8 ports each), why is STC displaying 16 ports per portgroup?

• When a user selects the LAG Profile, the change will apply to the entire appliance. • The quick answer to the question is: "The profile description is based on the 400G speed configuration set with default performance mode." • More details below... • The LAG Profile description does not change when the user selects a different speed. • Example 2x8 LAG Profile by default gives you 2 groups of 8x400G. (Total 16 ports, 8 in each group.) • If speed is set at 100G, the 2x8 LAG Profile will give you 2 groups of 32x100G. (Total 64 ports, 32 in each group) • For the A2-400-QD-16-T1S & on some other 400G appliances with ECM-Scaling mode enabled, the total number of active physical ports in the port group is halved. • Each port group which normally has 2x400G cages, breaks apart into 1x400G cage.  • Physical Ports 1,3,5,7,9,11,13,15 • Logical Ports 1,17,33,49,65,81,97,113 • Thus you will also see the port count halved in the LAG profiles: • The "2x8" LAG profile gives: • 2 groups of 4x400G (Total 8 ports, 4 in each group.) • or • 2 groups of 16x100G (Total 32 ports, 16 in each group) • Note that when using LAG profiles the logical port numbering changes to consecutive values starting from the initial logical port number. • Actually, you can also mix the speeds of each group.(see snapshot, note this is in ECM scaling mode) • 1 group with 4x400G • 1 group with 16x100G • • You can also choose to not use the ports in a LAG configuation but the group of ports will be considered as a single user group so when you reserve the ports, only 1 person can use them..
