I am reading documentation of Nexus 9000 Series NX-OS(https://www.cisco.com/c/en/us/td/docs/switches/datacenter/nexus9000/sw/9-x/command_references/921/show/b_N9K_Show_Commands_921.html)
I tried several "show" commands and none of them is working.
For example:
leaf# show ip bgp [hitting Esc key twice here to show options]
A.B.C.D IP address
A.B.C.D/LEN IP prefix
all Display BGP information for all address families
ipv4 Display BGP information for IPv4 address family
neighbors Display all configured BGP neighbors
nexthop Display routes matching the nexthop
nexthop-database Display nexthop database
summary Show summary information
leaf# show ip bgp summary
Incorrect command "show ip bgp summary"
leaf#
And:
leaf# show ip route [hitting Esc key twice here to show options]
A.B.C.D Display single route longest match lookup
A.B.C.D/LEN Display single exact match route
A:B::C:D Display single route longest match lookup
A:B::C:D/LEN Display single exact match route
bgp Display routes owned by bgp
detail Display routes in full detail
eigrp Display routes owned by eigrp
interface Display routes with this output interface only
next-hop Display routes with this next-hop only
ospf Display routes owned by ospf
summary Display route counts
updated Display routes filtered by last updated time
vrf Display per-VRF information
leaf# show ip route 10.36.136.51
Incorrect command "show ip route 10.36.136.51"
leaf#
As you see, the options are displayed when i hit Esc key twice, but if i choose any valid option, i get "incorrect command".
I am aware of bug CSCvi51338 where some show commands do not work for read-only users on a certain firmware version. But there is no extensive list which "show" commands fall under this bug. So, regarding my above mentioned show commands examples, do they fall under this bug or is it a potentially other bug. Or do I use CLI incorrectly?

Hi,
try to use in promt "vsh" to go to the Cisco iNX-OS Debug Shell. In this shell you can use "show ip route vrf xxx xxx.xxx.xxx.xxx.
When you are in ACI Shell use "show ip route vrf all xxx.xxx.xxx.xxx." or use the specific vrf.
Same for "show ip bgp summary". Specifiy the VRF during the execution of the command.
I hope this helps you, if yes, mark it as helpful :)
Kind Regards
Patrick

Hi fthgfhng,
I'm a little confused by your references to the documentation for the Nexus 9000 in NX OS mode and the APIC bug. "NX-OS" and "APIC" have virtually no relationship with each other.
Are you using the 9336C-FX2 in NX-OS mode or in ACI mode? If you are using it in ACI mode, the NX-OS manual is useless to you. The show version command output you pasted is VERY STRANGE - it has no version information at all! It SHOULD look more like this:
apic1# fabric 101 show version ---------------------------------------------------------------- Node 101 (Leaf101) ---------------------------------------------------------------- Cisco Nexus Operating System (NX-OS) Software TAC support: http://www.cisco.com/tac Documents: http://www.cisco.com/en/US/products/ps9372/tsd_products_support_series_home.html Copyright (c) 2002-2014, Cisco Systems, Inc.

Hi Chris.
How do I enter the ACI mode then?
When I issue "ls" command and choose "aci" I get this:
leaf221# ls aci bin controller debug dev etc isan lc lib mit proc sbin sys tmp usr var leaf221# aci bash: aci: command not found leaf221#
Same with "show vrf":
leaf221# show vrf <CR> Carriage return WORD VRF name all Display VRF information for all VRFs detail Display VRF detail information interface Display interface VRF information order Specify ordering leaf221# show vrf URL: http://127.0.0.1:7777/api//class/l3Ctx.xml?query-target-filter=eq(l3Dom.l3vmCfgState,"0")&page-size=200&page=0&order-by=l3Dom.name|asc Code: 403 Output: <?xml version="1.0" encoding="UTF-8"?><imdata totalCount="1"><error code="403" text="Need a valid webtoken cookie (named APIC-Cookie) or a signed request with signature in the cookie APIC-Request-Signature for all REST API requests"/></imdata> Data Posted: None Error executing command, check logs for details leaf221#
I agree, the show version output issued on the leaf switch is very strange (and this leaf is in production). I get the normal output when I issue this command from APIC:

Hi fthgfhng,
Definately something stange going on there - it does seem (now that you've finally established that the code is version 13.1(2m)[Switch]/3.1(2m) [ACI]) that this could well be related to the bug you mentioned. (CSCvi51338)
Is doing a firmware upgrade possible? That's what I'd have to recommend at this stage.

try specifying a VRF when using the show commands via "vrf overlay-1" or whatever VRF you need to see in ACI mode. Do a "show vrf" if you don't know the format
