Hi
I'm ready to the ACI PoC, in the mobile network environment.
The APIC is operate normally. Then as shown in the following message:
--------------------------------------------------------------------------------------------------------------
SERVER ERRO
The Policy change was net implement due to internal communication failure from
the APIC to other APICs/nodes on the fabic, please retry request
--------------------------------------------------------------------------------------------------------------
In order to solve the problem, I had reset all the APIC(3) using a command "eraseconfig setup"
After the APIC reset, does not auto discovery nexus 9000(leaf/spine) switch and other APICs
leaf switch APIC connected as follows in its port state is:
leaf-1# show interface ethernet 1/3
Ethernet1/3 is up (out-of-service)
admin state is up, Dedicated Interface
Hardware: 100/1000/10000/auto Ethernet, address: 88f0.31dc.87d9 (bia 88f0.31dc.87d9)
MTU 9000 bytes, BW 10000000 Kbit, DLY 1 usec
reliability 255/255, txload 1/255, rxload 1/255
Encapsulation ARPA, medium is broadcast
Port mode is trunk
full-duplex, 10 Gb/s, media type is 10G
Beacon is turned off
Auto-Negotiation is turned on
Input flow-control is off, output flow-control is off
Auto-mdix is turned off
Rate mode is dedicated
Switchport monitor is off
EtherType is 0x8100
EEE (efficient-ethernet) : n/a
Last link flapped 00:10:51
Last clearing of "show interface" counters never
2 interface resets
30 seconds input rate 0 bits/sec, 0 packets/sec
30 seconds output rate 0 bits/sec, 0 packets/sec
Load-Interval #2: 5 minute (300 seconds)
input rate 48 bps, 0 pps; output rate 0 bps, 0 pps

36 output packets 11765 bytes
0 jumbo packets

0 lost carrier 0 no carrier 0 babble 0 output discard
0 Tx pause
I think, I have to do initial setup (ACI mode factory default) nexus 9000(leaf switch)
Could you tell me what I should do?

Hello,
You are correct, you would need to clean the configuration on the leaf and spine switches as well. Since they were registered to a fabric at one point and the APICs were erased, the switches still have their configuration. This is because the switches operate independently of the APICs, the APIC only pushes new policy/configuration. Since the APICs were erased and formed a new fabric, the leaf switches do not know of the new fabric and can only be a part of one fabric at a time, thus they must be erased whenever the APICs are erased.
On the switches, the appropriate command to erase the configuration is setup-clean-config.sh <image.bin>. It is suggested you first look at boot flash and copy the ACI image name to then insert as an argument into that command. Also, I suggest you setup boot variables first with the setup-bootvars.sh <image.bin> command. In summary:
When the switches reload they should return to the (none)# prompt, at which point the APIC should discover its directly connected leaf and the discovery and registration process can proceed from there. I hope this helps, have a nice day
