How to check physical interface status on Nexus 9504 via CLI?

I am googling around trying to find out how to check physical interface status of a switch in ACI environment via CLI. If I ssh to a leaf switch and issue "show interface x/y" I get the following:

 

URL: http://127.0.0.1:7777/api//class/nwIf.xml?&target-subtree-class=mgmtMgmtIf&query-target=subtree&order-by=nwIf.id|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

 

I tried to ssh to APIC and issue these commeands but no luck:

 

apic1# config
apic1(config)# leaf 103
apic1(config-leaf)# interface eth 1/7
apic1(config-leaf-if)# show
Error: Invalid argument ''. Please check syntax in command reference guide
apic1(config-leaf-if)#

 

I used "show" keyword because I saw one example where the same commands are issued but instead of just "show" you must use "show running-config", like this:

 

apic1(config)# leaf 103
apic1(config-leaf)# interface ethernet 1/2.150
apic1(config-leaf-if)# show running-config
# Command: show running-config leaf 103 interface ethernet 1 / 2 . 150
# Time: Tue Dec 8 08:08:37 2015
leaf 103
interface ethernet 1/2.150
vrf member tenant t1 vrf v1
ip address 169.10.10.1/24
ip router ospf default area 0.0.0.1
exit
So I thought if I just issued "show" keyword, the I will get the interface statistics, just like in using IOS command "show interface x/y"

Re: How to check physical interface status on Nexus 9504 via CLI?

Hi Blackschwanzer,

From the APIC, put the word fabric followed by the node id, followed by a regular command - use anywhere along the way to get help.  For example, to examine ethernet interface 1/1 on the switch with ID 201, issue the command

fabric 201 show interface ethernet1/1

(See output below)

This should give you exactly the same output as issuing the command

show interface ethernet1/1

on the actual switch from an ssh session.  I'm not sure why you got the error message shown, but the command syntax is show interface ethernet x/y - not show interface x/y

Re: How to check physical interface status on Nexus 9504 via CLI?

thank you Chris, your suggested command works!

Regarding the show command issued from the leaf itself, yes, I meant "show interface ethernet x/y". And I still get the same error, but it does not matter now since I can check the interface status from the APIC.

Still, it's interesting what this error is about. Maybe I have to go into some special mode before issuing the show interface command.

Here is a bit more clues, maybe someone had experience with this:

leaf# show interface ethernet 1/50
URL: http://127.0.0.1:7777/api//class/nwIf.xml?&target-subtree-class=mgmtMgmtIf&query-target=subtree&order-by=nwIf.id|asc

Alright, that error message is a known bug CSCvi51338

Re: How to check physical interface status on Nexus 9504 via CLI?

Just an FYI - when you issue commands from the APIC using the fabric xxx prefix, you can use the ? key as per normal NXOS/IOS CLI.

When you have a session directly with a leaf switch, the ? key doesn't work. <Tab> still works, but not ? However, there is an alternative.  When you need help, hit <Esc><Esc> and you will get help similar to ?

E.g.

Leaf101# show interface <Esc><Esc>

Re: How to check physical interface status on Nexus 9504 via CLI?

And just to extend the discussion about the show commands - how could I check the logs of a spine/leaf switch?

Because now, if I issue "fabric 220 show logging" from the APIC, I get "incorrect command" error message:

 

apic1# fabric 220 show logging
----------------------------------------------------------------
Node 220 (leaf2)
----------------------------------------------------------------
Incorrect command "show logging"

apic1#

 

I can only see logging of some access list cache:

 

apic1# fabric 220 show logging ip ?
access-list Access-list
apic1# fabric 220 show logging ip access-list ?
cache show entries in ACLLOG cache
drop-codes Drop Codes
internal Show internal acllog information
span show entries in ACLLOG span
apic1# fabric 220 show logging ip access-list cache ?
deny action is deny
permit action is permit
apic1# fabric 220 show logging ip access-list cache deny ?
<CR> Carriage return
apic# fabric 220 show logging ip access-list cache deny

 

And I cannot issue "show logging" locally on the switch due to earlier mentioned bug.
