NSX native load balancer returns 502 Bad Gateway? Check the header size limits in the HTTP application profile, find the 502 in the Edge LB error and access logs, and verify pool and server-side SSL.
VMs on the same NSX segment talk on one host but not across hosts? Check TEP-to-TEP connectivity and MTU with vmkping, read tunnel BFD state in vmkernel.log and uplink events in vobd.log.
Why a Tier-0 BGP session to the ToR does not come up (VLAN ID or BGP configuration mismatch), how to check it from the NSX Edge CLI, and how to read frr.log and syslog.
Host Down or Host Disconnected in NSX? Which NSX host agent is behind it (nsx-proxy, nsx-opsagent, nsx-cfgagent, nsx-nestdb), how to check and restart it on ESX, and which logs to read.
How VMware Cloud Foundation approaches distributed security with NSX, based on the VMware Explore EU 2024 session and what it means for VCF designs.
NSX remote logging not configured? Set a syslog server on NSX Manager and Edge with set logging-server, check it with get logging-servers, find local logs.
Essential NSX commands on NSX Manager and ESXi: transport node status, TEP/VTEP info, VIFs, NSX VIBs and agents, vmkping over the TEP stack, and log files.
Manage the NSX Manager cluster from the CLI: cluster status and config, detach and join manager nodes, and the NSX Manager log files for troubleshooting.
NSX DFW from the CLI: firewall status, rule summary and exclude list on NSX Manager, per-host checks on ESXi, DFW log files and gateway firewall on Edge.
NSX logical routing troubleshooting from the CLI: gateways, interfaces and routes on NSX Manager, BGP and OSPF on the Edge (vrf), and checks on ESXi hosts.
