ASR9001 Port Numbering

[dfranjoso]

Hello,

Does anybody knows the port numbering used on the Cisco ASR9001 for the

Left MPA

Right MPA

Built-in 10GbE interfaces

I'm assuming that with NV technology in place, the chassi number would be 0 for the primary DSC and 1 for the secondary DSC.

Thanks!

David

Hello David,

Left slot is named Bay 0, so, no surprise, that would be 0

Right slot is named Bay 1, so 1.

The build in port are treated as in slot 2.

Bay 0 - 0/0/0/x

Bay 1 - 0/0/1/x

The buildin ports:

      TenGigE0/0/2/0

      TenGigE0/0/2/1

      TenGigE0/0/2/2

      TenGigE0/0/2/3

Yes, with the cluster we get 1 for the second chassis:

RP/0/RSP0/CPU0:ios#show platform

Node            Type                      State            Config State

-----------------------------------------------------------------------------

0/RSP0/CPU0     ASR9001-RP(Active)        IOS XR RUN       PWR,NSHUT,MON

0/0/CPU0        ASR9001-LC                IOS XR RUN       PWR,NSHUT,MON

0/0/0           A9K-MPA-20X1GE            OK               PWR,NSHUT,MON

0/0/1           A9K-MPA-4X10GE            OK               PWR,NSHUT,MON

1/RSP0/CPU0     ASR9001-RP(Active)        IOS XR RUN       PWR,NSHUT,MON

1/0/CPU0        ASR9001-LC                IOS XR RUN       PWR,NSHUT,MON

1/0/0           A9K-MPA-20X1GE            OK               PWR,NSHUT,MON

1/0/1           A9K-MPA-2X10GE            OK               PWR,NSHUT,MON

Once again thanks Alexei.

Of course the HW documentation guide has several bugs (but you are always here to help!)

"

Remember that Cisco ASR 9001 Router rack and subslot values are always 0 (zero).

"

which contradicts

"

The line card slot is numbered 0 with three subslots. The subslots on the line card are numbered 0, 1, and 2. 0 and 1 are reserved for EP ports and 2 is for native ports on the line card. Even if the line card contains only one port, you must use the rack/slot/instance/port notation.

"

I'll stick to this last paragraph, as you confirm.

PS: I did ask for 2 ASR9001 from Cisco demo depot, but they are being built and delivered only in a couple of weeks !!! Can you lend my yours ?
