ASR 9902 Interface numbering

[brian.holmes]

This is a fixed port router with a mix of SFP+, SFP28, QSFP28 and QSFP-DD ports

The install guide says they are split between slice 0 and slice 1 with 24 ports per slice

How does this translate into the rack/slot/instance/port schema ?  is the slice the instance?

is it ...

0/0/0/0-0/0/0/7 - SFP28
0/0/0/8-0/0/0/10 - QSFP28
0/0/0/11 - QSFP-DD
0/0/0/12-0/0/0/23 SFP+

and

0/0/1/0-0/0/1/7 - SFP28
0/0/1/8-0/0/1/10 - QSFP28
0/0/1/11 - QSFP-DD
0/0/1/12-0/0/1/23 SFP+

Unfortunately I do not have one of these in my possession but am trying to put together a solution based on them ( a drawing of which circuits goto which port numbers )

[brian.holmes]

Based on the output you showed it looks like it might be the following but it is a little hard to tell:

0/0/0/0-0/0/0/7 - SFP28
0/0/0/8-0/0/0/10 - QSFP28
0/0/0/11 - QSFP-DD
0/0/0/12-0/0/0/35 SFP+
0/0/0/36-0/0/0/38 QSPF28
0/0/0/39 QSFP-DD
0/0/0/40-0/0/0/47 SFP28

check out slide 85, hope it helps with the picture.

you can map the picture with the lab output hope it helps, unfortunately its not as straight forward depending on the breakout configuration you use. slide 88 will show you combinations of used/unused

Thank you, this helps very much.   So the Port numbering does not change as in slide 88...but which are active depends on the breakout configuration you configure.
