Something is odd here:
I was looking at Cisco Catalyst 4500 Series Supervisor Engine II-Plus-10GE, datasheet here:
I realised that if I use this on Cat 4506 or 4507R chassis, I'll get a switching fabric of 108Gbps on each.
On the contrary, Table 2 of the same link above depicts that;
Layer 2-4 Performance of Supervisor Engine II-Plus-10GE is 108 Gbps AND that of Supervisor Engine V-10GE is 136 Gbps.
What should I be concerned about? Switching fabric or L2/3 performance?
Obviously SUP V has higher performance on L2-3 front.
Now if I browse through;
I see that;
Evn though, Supervisor Engine V L2-4 performance is stated to be 96gbps, it's switching fabric support for 4506 Chassis is mere 64 Gbps, and that of 4507R is mere 68 Gbps.
Much worse for the two Catalyst models than that of Sup II + 10GE.
Am I missing something here or is my analysis correct? Is Sup V giving worse performance than Sup II plus?
