A99-RSP-SE and -TR Line cards

[malinda1]

According to my understanding if we replace A99-RSP-TR with A99-RSP-SE on a Chassis with -TR Line card the router will function normally. But can that improve the performance of the router ? 

Is it recommended to mix -SE RPs with -TR LCs?

Hello @malinda1 

-SE line cards: prefer use this card for the connection of customer environments such as PE interconnections to take advantage of this card. This is an advanced QoS services card with the capacity to manage up to 256,000 queues per port.

-TR line cards , this card is preferred for backbone connections.

As concerned RSP-TR or SE...you need RSP-SE to insert SE line card. If you have only TR line cards inserted on your plarform with RSP-SE, so improvment should not be very important.

you can mix -SE RP's and -TR/-SE Line Cards this is supported

however you should not mix -SE and -TR RP's due to the memory differences.
these slides have the differences in the latest RPs

Thank you @tkarnani for the explanation, will mixing -SE and -TR RP's work temporally during a transient period so that we can do TR to SE without a downtime.

Hi,
There is a difference between the total memory between these RSP's
Temporarily during migration you should be able to swap as long as the memory utilization is low
Keeping them mixed for long can cause issues due to this
