CSS Even and Odd VLANS

On the Catalyst 5000 architecture, all Even VLANs are running on one BUS on the backplane and all the odd VLANs are running on the other BUS on the backplane. Is CSS work in the same way? Hence, is it going to be a problem if I have all Even VLANs or all Odd VLANs?

Thanks,

Re: CSS Even and Odd VLANS

David,

The CSS does not work in this manner so your vlans can be odd or even and have not effect on the css. The only thing to keep in mind is that ever 4 ports, 1-4, 5-8, 9-12, etc.. are on separate EPIFs. So when doing network planning, you may want to consider separating connections.

For example, if you are only using a few ports on a CS150, it would be beneficial to use ports 1,5 and 9 as they are all on different EPIFs.

Re: CSS Even and Odd VLANS

Pete,

Thanks for your reply. Curious, if I have a 2 port Gigabit card on CSS11506, will I have 1 XPIF or 2 XPIFs?

Also, does slot matter? That is, can I use any slot I want without worrying about performance?

Thanks
