Part 2 – How to list vSwitch “MAC Address table” on ESXi host?
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. 🙂
Part 1 – How to list vSwitch “MAC Address table” on ESXi host?
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…
vSphere 6.5 – What’s new in networking Â
In this article I will try to review all new network features. 1. vmknic gateway Each VMKERNEL port can have its own Gateway. This will make it easy for vSphere features to function seamlessly. This eliminates the need for adding and maintaining static routes. Before vSphere 6.5 there was only one default gateway allowed for all VMKernel ports in an ESXi host. vSphere features such as DRS , iSCSI, vMotion, etc. leverage that use VMKERNEL ports are constrained by…
How to monitor virtual network – story about netflow in vSphere environment.
Before we start talking about NetFlow configuration on VMware vSphere let’s back to basics and review protocol itself. NetFlow was originally developed by Cisco and has become a reasonably standard mechanism to perform network analysis. NetFlow collect network traffic statistics on designated interfaces. Commonly used in the physical world to help gain visibility into traffic and understanding just who is sending what and to where. NetFlow comes in a variety of versions, from v1 to v10. VMware uses the IPFIX…
Network virtualization for Dummies – from VMware
VMware shared a free ebook – Network Virtualization for Dummies. It’s the next book from seriers “for Dummies”. The main goal of the series is to describe technical aspects in the most clear and easy way as possible. I haven’t read this one yet but “Virtualization for Dummies” was quite good in my opinion. If you are keen on network virtualization topic, I strongly encourage you to download it here.
