In the baove command, DevID is the Switch name and PortId is the Ethernet port on the switch.Įxecute the below command to identify the Switch Name and Switch Port in which you vmnic “vmnic1” is Connected: ~ # vim-cmd hostsvc/net/query_networkhint –pnic=vmnic0 | egrep ‘portId|devId’ĭevId = “(SSI55030KNE)”, This command can also be used when you connect your ESXi host using SSH connection.Įxecute the below command to identify the Switch Name and Switch Port ID in which your vmnic “vmnic0” is Connected:
This post helps you to achieve this just from the ESXi shell from your console Connection such as ILO or DRAC. How to do identify the CDP information and collect the network switch and Port details in which your ESXi host vSwitch or vmnic is connected. You are not able to connect to your ESXi host using Putty or vSphere Client. Ok, Let’s imagine the situation, ESXi host is not reaching in the network. This information is useful when troubleshooting network connectivity issues related to VLAN tagging methods on virtual and physical port settings. You will be able to see the properties of the Cisco switch, such as device ID, software version, and timeout from the vSphere Client when the CDP is enabled on the vSwitch. As ESXi admin, We will not be knowing much information about the physical switch configuration for our ESXi host but still we will be able to get the phsyical switch information using the CDP (Cisco Discovery Protocol). The Cisco Discovery Protocol (CDP) is a Cisco’s proprietary Data Link Layer protocol used to share information about other directly connected Cisco equipment, such as upstream Physical switch.ĬDP allows ESX and ESXi administrators to determine the vSwitch is connected to which Cisco switch port.
This post will be really helpful when you are troubleshooting your ESXi host network communication issue.
