WS-X6548-GE-TX, however you will also need a SFM module (WS-X6500-SFM2) as the Supervisor II does not have a fabric connection to the chassis.
Thank you, but this card doesn't seem to be fabric-enabled. I did, however, find the WS-X6748-GE-TX, which looks as if it is fabric-enabled. I wonder if it will work with Sup II's?
Does the oversubsription rate on each port (1.2:1) only come into play if the 40 limit is reached?
8Gbps connection to switch fabric.
So each group of 6 ports will get 1Gbps shared between them to the switch fabric. So if you want to avoid oversubscription you can use just 8 ports and each of those ports would get 1Gbps dedicated.
Note that depending on the module the port groups are not necessarily sequential and from memory i can't recall how the port groups are made up on a 6548.
On the 6548, they are grouped sequentially.
I used to post information without looking it up, until you correct me on the 6548 being fabric on a previous post :)
In which case you are right about it being 40 ports as the 6748 has 2 x 20Gbps connections to the switch fabric.
I'm going to leave it to Edison for the port groupings :)
So can I assume that an individual port will not go into oversubscription if the group it is in is not bandwidth exceeded?
What I mean to ask is if it is a port by port thing. :)
Correct, and that module also provide 1Mb buffer per port as opposed to 1Mb per 8 ports on the x6548.
If I have a 6506E and slot 5 has my sup-720-3b should my WS-X6748-GE-TX be in slot 6? Or will I get what we have discussed in slot 1?
You will get the full throughput in any slot in the 6506E as you would with the 6509.
The only chassis you need to be careful with is the 6513 where each slot does not necessarily support 2 x 20Gbps to the switch fabric.
I would leave slot6 for your Secondary Supervisor.
While it should work on slot6, that slot has special power allocated for Supervisor modules.
Choose any slot other than slot5 and slot6, if available.
