It took me a while to figure out what information I see while displaying VTEP, MAC and ARP table on Controller Cluster in NSX. In documentation you can find what information are included in those tables but it might not be seemingly obvious which field contains what kind of data that’s why I decided to make a short reference for myself but maybe it will help also someone else. To understand those tables I started with Central CLI to display…
The other way to list MAC addresses of open ports on vSwitches on the ESXi host is based on net-stats tool. Use this one-liner. for VSWITCH in $(vsish -e ls /net/portsets/ | cut -c 1-8); do net-stats -S $VSWITCH | grep \{\”name | sed ‘s/[{,”]//g’ | awk ‘{$9=$10=$11=$12=””; print $0}’; done This is not a final word. 🙂
Sometimes You need to list MAC addresses loged on host’s vSwitches to eliminate VM’s MAC address duplicates. Create a shell script: vi mac_address_list.sh Copy and past the code listed below: #!/bin/sh #vmrale for VSWITCH in `vsish -e ls /net/portsets/ | cut -c 1-8` do echo $VSWITCH for PORT in `vsish -e ls /net/portsets/$VSWITCH/ports | cut -c 1-8` do CLIENT_NAME=`vsish -e get /net/portsets/$VSWITCH/ports/$PORT/status | grep clientName | uniq` ADDRESS=`vsish -e get /net/portsets/$VSWITCH/ports/$PORT/status | grep unicastAdd | uniq` echo -e “\t$PORT\t$CLIENT_NAME\t$ADDRESS” done…
