Hi, there. A little bit off topic but your post is the only one related to C9600 I can find on this forum so far. So just like to ask have you install C9600 into production? if so, what is your feedback & feeling compare to C6800 or C6000? Thanks. Leo

I opened a TAC case a while back, the answer from TAC is that you have to "call" TAC to clear this error for you, as they cannot release the tool to clients. We upgraded to 4.1.1j which fixed this annoying problem.

I am trying to configure AAA on ACI to allow system operators to be able to acknowledge faults with minimum Privileges and without any admin read/write privileges. Tried few privileges but not successful, just wondering has anyone done something similar? Thanks. Leo

Yes, OOB is defined and the external syslog server can receive system level logs originated from APIC, but not the logs originated from spine, leaf like a leaf interface goes down. I sense it is the configuration problem but cannot figure out where went wrong.

I think I did. By the way, we are running 4.0(1h). 1. Fabric -> Fabric Policies -> Policies -> Monitoring -> Default -> Callhome / Smart Callhome/SNMP/Syslog [cid:image001.jpg@01D4F43A.D67920D0] 2. Fabric -> Fabric Policies -> Policies -> Monitoring -> Common Policy -> Callhome / Smart Callhome/SNMP/Syslog [cid:image002.jpg@01D4F43A.D67920D0] 3. Fabric -> Access Policies -> Policies -> Monitoring -> Default -> Callhome / Smart Callhome/SNMP/Syslog [cid:image003.jpg@01D4F43A.D67920D0]

Unfortunately, ACI (at least for now) won't allow us to modify VLAN pool, only deletion and creation. What we did is to create multiple small VLAN pool (say 10 VLANs in each pool) as a "work around". Hopefully, the future ACI will fix this.

I setup syslog on ACI to let log informational syslog to external syslog server, and I think the configuration is correct on various places on ACI but only the external syslog server only receives system wide syslogs without the syslogs from leaf or spine, like one leaf switch port going down. Has any successfully setup the ACI syslog and you syslog servers can receive all of the logs? Thanks.

Sairam. I would recommend you ask your Cisco account manager and let them handle this.

Hi, Does anyone the OID to SNMP get the overall ACI system health score (System -> Dashboard -> System Health ? Thanks.

John. It is possible, we have VMs tagging multiple IPs and been assigned to different EPGs. Leo.

John.
What we did here is for those appliances or hosts with multiple Interfaces / IPs, we will assign 1 EPG per 1 IP.

John. I would prefer to have multiple of EPGs assigned based on different IP addresses. Logically it is very clear and still leveraging IP address as End Point Identity. Depends on your web hosting infrastructure and policy, we might consider enable Intra EPG isolation so no 2 EPs on the same EPG can communicate with each other.

Thanks for your further explanation, by putting the base EPG into PVLAN mode.
Then any communications between 2 VMs will be forwarded to upstream Leaf and handled by Leaf, will this cause any potential performance or scalability issues if the the number of PVLANs increase? Is there any rule of thumb in terms of micr-segmentation design? thanks.

We have few application EPGs under a same BD domain, and like to create a uSeg EPG based on VM tag, like DEPT=HR for example.
I believe we need to check "Allow Micro Segmentation" in the "VMM Domain Association" part. The uSeg EPG is created and VMs can move into this new uSeg EPG should its VM TAG DEPT=HR condition meets. But we found out 2 Private VLANs are created at the "base" EPG / PortGroup, hence, the rest VMs cannot communicate with each other, just like enable Intro-EPG Isolation.
Is this behavior expected, or we did something wrong? Thanks.

We won't purchase DCF4 on 67xx 1G LCs, my goal is to ensure 6724/48 CFC 1G LC can coexist with 68xx 32P10G in C6807-XL w/ SUP2T, and migrate 1G from 6724/48 CFC to 6800-32P DFC4 gradually.
