[j-nsp] MPC5EQ Feedback?

[Hunter, David B.]

Scott,

Just FYI, you may already be aware of this, but there was one limitation with the MPC5E that we ran into.  We use the MPC5E-40G10G, which are working fine in our data center for 40Gbs service.  I think the EQ version is the same in regards to the limitation we discovered.  At the time we purchased the cards, it wasn’t well documented as to how the 10 and 40Gbs ports could be used.  Juniper has since updated the documentation to specify the allowed port usage.

The card is not oversubscribed, the limit seems to be a hard 240Gbs for the entire card imposed by the way in which the PICs can be used.

“...Supports one of the following port combinations:
• Six 40-Gigabit Ethernet ports
• Twenty-four 10-Gigabit Ethernet ports
• Three 40-Gigabit Ethernet ports and twelve 10-Gigabit Ethernet ports”
