TCAM information on 7750SR

[sheaujic]

Hi all,

Anybody has information related to TCAM on 7750?

I have the below questions
1. Do SR boxes use TCAM heavily for routing decisions?
2. Are there other usage of TCAM beside routing decisions?

Is there any documents that talk about TCAM that can be shared?

The IOM/IMM datasheets don't seem to have made it from the old Alcatel-Lucent site to the Nokia one after the acquisition and finding the information is harder than it should be.

Google for "IMM_R10_EN_Datasheet.pdf" and you should find an old data sheet for SR OS Release 10 with the following info:
