We talked about the Cisco Transceiver Modules a lot before, such as the S-Class Optics vs. Non-S-Class Optics, the CVR-X2-SFP10G & CVR-X2-SFP10G=, and the Cisco 10GBASE X2 Module & SFP Compatibility.

These are all the popular questions asked by customers. Here in this article we will continue to share the Cisco 6807-XL Slots issue put forwarded by Cisco users. What did they discuss about that? Let’s see the details…

The Question: “I want to choose 6807-XL as a core switch in my project, but I have question! Can I use 6 cards as a module and 1 as SUP 2T or I must use 5 Slots for modules cards?? Because I need One SUP 2T and I want to use the rest of 6 slots for module cards, Can I do that?”

…The pinouts between the module slots and sup slots are different. So slots 5 and 6 are reserved for sups and can't be used with regular modules.

So is there any model more than 7 slots from 6800 series?

Another Question: “There is a difference between X2-10GB-SR= and SFP-10G-SR= because I want to replace the WS-X6816-10G-2T card with C6800-32P10G-XL which can carry 32 ports 10G with One card so I can save one slot! Can I do that?”

…The Cisco 6807 is the larger chassis you can get on the 6800 series. As for 16 port 10Gig vs. 32 port 10Gig, you can defiantly use the 32 port 10gig module to solve the issue if not having enough slots for all your 10Gig interfaces. Also, you can enable VSS on the 6800 series to give you the redundancy you need without using HSRP/VRRP, etc...

“And but 16port 10Gig uses Pluggable transceivers X2-10GB-SR= and 32port 10Gig uses Pluggable transceivers SFP-10G-SR=?! Is there any difference between them? Or both them the same!”

You need the 16 port 10Gig SFP+ or the 32 port 10Gig SFP+

See this link for part numbers and descriptions:


Two models:

C6800-16P10G, a 16-port 10-Gigabit Ethernet Fiber Module with DFC4, and C6800-16P10G-XL, a16-port 10-Gigabit Ethernet Fiber Module with DFC4XL

C6800-32P10G, a 32-port 10-Gigabit Ethernet Fiber Module with DFC4, and C6800-32P10G-XL, a 32-port 10-Gigabit Ethernet Fiber Module with DFC4XL

The difference between WS-X6816-10G-2T card and C6800-32P10G-XL?

X2 and SFP are different form factors. On some of these, you CAN get a twinGig adapter to convert an X2 into multiple SFP ports, but I don't think these can be 10G SFP+ (although it may be possible on the newer modules).

There shouldn't be a performance difference between SFP+ or X2. However, check the capability of the line card / chassis backplane - if you have 16 10G ports, make sure the line card plugged into supports what you expect. Remember, if all ports are 10G running flat out, your total backplane for that line card is 160G, unless it's between servers in the same VLAN connected to the same blade.
