<p>From the data sheet I can see that 12810 supports 40G/slot. Does that mean it 40G full duplex or 80G full duplex. If its only 40G full duplex, how can we get a switching capacity of 800Gbps for the system (40 X 10 = 400Gbps only)?</p>
<p>If its a 80G full duplex, it should support a line card of 4 X 10GE, right? But Cisco has not released any 40G (single or 4 X 10GE) interfaces for 12810 or 12816. Any specific reason? Even SIP-601 supports only 10G.</p>
<p>Customers say Cisco claims 40G/slot on 12800 but there are no line cards or SIP to support this claim.</p>
the numbers used to define a chassis capacity are the result of summing tx and rx capacities.
All vendors do so and when we focus on a technical point of view this fact becomes clear.
In addition to first note: a GSR has a non blocking switching crossbar so the capacity of the fabric is superior to that of single linecards (and this is indeed a good point to avoid internal bottlenecks)
So the current linecards don't include a real 40 GE capable linecard and you are right about this.
We are pleased to announce availability of Beta software for 16.6.3. 16.6.3 will be the second rebuild on the 16.6 release train targeted towards Catalyst 9500/9400/9300/3850/3650 switching platforms. We are looking for early feedback from custome...
