I don't think you can enable SNMP on the Standby.   I just tested shutting down the fabric ports towards the Standby controller on 3.2(3o).   Surprisingly there was no fault raised and nothing in the event log other than me shutting these ports down.   I did see that the Standby vanished from the Cluster as Seen By Node screen under Controllers > Node-N though. You can see this via the API:   https://APIC_IP_ADDR/api/node/mo/topology/pod-1/node-1.json?query-target=subtree&target-subtree-class=infraSnNode&query-target-filter=and(eq(infraSnNode.apicMode,"standby"),ne(infraSnNode.cntrlSbstState,"erased"))&query-target=subtree&target-subtree-class=infraSnNode,infraWiNode ...

You can see Global Endpoints under Fabric > Inventory > Topology > Global End-Points, but it doesn't look like you can sort or filter the output by the leaves on which they are learnt.   You can see the routes, ARP, CDP, LLDP, many other values under the Fabric > Inventory > Pod N > Leaf > Protocols, but it appears the endpoint tables  and MAC tables are not visible in the GUI.   I think this would be something best done on the CLI or with your own API queries. ...

All the 3.2 train releases had a bug until 3.2.3o which caused issues with 25Gb negotiation. This bug was resulting in unstable or no link unless FEC was disabled in a deployment with 93180YC-EX and Broadcom 57414 NICs.   See CSCvm46784. If you are on an earlier 3.2 I would consider upgrading. ... View more

The catalog numbering standard has been changed in new releases. That will be the catalog that came with the 3.2 you loaded. They no longer align with the release number. I think it’s so they reflect how recent the catalog is regardless of the code train you are on.  ... View more

The requirement is that the IPN needs to pass the packets without fragmentation being necessary. Sending pings between switches is just one way to verify this is happening. The fact that some pings drop due to CoPP will have no impact on IPN performance*.   *Unless CoPP is doing things like dropping adjancencies etc. ... View more

You don’t have to adjust it. In normal operation you won’t be having 9000byte flood pings hitting the CPU.    There is no ”correct” value. It depends on the network and what is normal.  ... View more

GOLF has it’s own caveats, mainly limited support on the upstream routing platforms and lack of multicast support.    A future release will support /32 advertisement in regular L3Outs (which is the main advantage of GOLF in non large scale environments). Once this happens the driver to use GOLF is largely gone in enterprise environments. ... View more
