How to check ASR9k is 32bit or 64bit?

[FrankHu114051]

What is the command to see my ASR9k is runnung 32 or 64 bit?

[Seb Rupik]

Hi there,

Not sure there is a platform command, but as a good rule of thumb if an OS has more than 4GB of system memory then it must be a 64bit OS.

cheers,

Seb.

Could you provide an example to show "OS has more than 4GB of system memory" - Thanks a lot!

[Seb Rupik]

show system resource

...will tell you how much memory is available on each card.

[Cosmin]

Yeah...well...that's bull**bleep**! And it's misleading for someone who doesn't know!

There is no rule of thumb that says that and there are a lot of routers that have 8Gb of RAM and they run on 32bits.

"As a rule of thumb" next time try searching the official Cisco documentation.

This may answer your question more specifically:

https://community.cisco.com/t5/service-providers-documents/ios-xr-release-strategy-and-deployment-recommendation/ta-p/3165422

...check your OS binary file name.

We can check from two easy clis as follows

• admin show platform
• admin show version

Yeah x64 in the image name (show install act summ) stands for 64bit. If missing, means 32 bit.

[Elvin Arias]

When I am working on an ASR9K, I usually spot wether the platform is 32-bit or 64-bit by executing the "show platform" command.

Outputs will be different.

RP/0/RSP0/CPU0:router:router(admin) # show platform
Wed Jul  3 11:34:18.487 UTC
Node            Type                      State            Config State

0/RP0/CPU0      ASR-9922-RP-SE(Active)    IOS XR RUN       PWR,NSHUT,MON <<< State for 32-bit would be IOS XR RUN.

sysadmin-vm:0_RP0#show platform

Location  Card Type               HW State      SW State      Config State
----------------------------------------------------------------------------
0/0       NC55-36X100G            OPERATIONAL   OPERATIONAL   NSHUT <<< State for 64-bit is OPERATIONAL.
