Hi ,

Can you enable IP Device Tracking  for the discovery. Please check out this  - APIC not discovering hosts in campus environment

Also please mention which version of APIC-EM are you using?

Thanks and Regards,

Geevarghese

Hi Geevarghese,

the issue seems to be with routers, not hosts?

i have configured the credentials for admin the same as it is configured on the device (it is the same in the three routers so example  i configured admin privilege 15 password 0 pwd in apic i just enter the name admin password pwd and enable pasword for example pwd ! how i can i ssh to devices ?

By default APIC-EM only supports sshv2 (not version 1).

You can check ssh access from a terminal window.  ssh user@device, where 'user' is the username and device is your router IP address.

here are instructions for configuring sshv2 on cisco router. http://www.cisco.com/c/en/us/support/docs/security-vpn/secure-shell-ssh/4145-ssh.html#sshvvs

hi i'm working with apic em version 1.3.3.126 and yes i'm talking about routers

You need to have the correct credentials for the device.  If APIC-EM says the device is ping reachable, and CLI validation failed, it means that APIC-EM does not have the right credentials to ssh to the device.

Can you ssh to the device from APIC-EM?  Are those credentials (username/password) part of the discovery job?
