Short Story: login on HCX manager via ssh and perform some troubleshooting with CLI commands.
Could be useful know some easy HCX commands to discover network issues from On-prem networks and VMC on AWS.
# ssh admin@<hcx manager> [admin@HCX-MGR ] ccli Welcome to HCX Central CLI [admin@HCX-MGR ] hc <probe health check about configuration> [admin@HCX-MGR] list <list of HCX fleet with ID, node name, IP address and state>
use this command to login into a fleet where 0 is an example of ID node and use ssh command to enter on fleet.
[admin@HCX-MGR] go 0 Switched to node 0. [admin@HCX-MGR] ssh Welcome to HCX Central CLI [root@<name of the fleet> ] ip tun <status of gre tunnel> [root@<name of the fleet> ] tcpdump -c20 -i vNic_0 -n -e host <wan ip address of remote side>
to perform network tests on tunnel use those commands
