The MTU is the size, in bytes, of the largest protocol data unit the switch can process. When you set this
option, it aects all uplinks assigned to the virtual switch.
n
Set the CDP value for a vSwitch. You can set status to down, listen, advertise, or both.
esxcli <conn_options> network vswitch standard set --cdp-status=listen --vswitch-
name=vSwitch1
Setting Switch Attributes with vicfg-vswitch
You can set the maximum transmission unit (MTU) and CDP status for a virtual switch. The CDP status
shows which Cisco switch port is connected to which uplink.
Specify one of the options listed in “Connection Options for vCLI Host Management Commands,” on
page 19 in place of <conn_options>.
n
Set the MTU for a vSwitch.
vicfg-vswitch <conn_options> -m 9000 vSwitch1
The MTU is the size, in bytes, of the largest protocol data unit the switch can process. When you set this
option, it aects all uplinks assigned to the virtual switch.
n
Set the CDP value for a vSwitch. You can set status to down, listen, advertise, or both.
vicfg-vswitch <conn_options> --set-cdp 'listen'
Checking, Adding, and Removing Port Groups
You can check, add, and remove port groups with ESXCLI and with vicfg-vswitch
Managing Port Groups with ESXCLI
You can use esxcli network vswitch standard portgroup to check, add, and remove port groups.
Network services connect to vSwitches through port groups. A port group allows you to group trac and
specify conguration options such as bandwidth limitations and VLAN tagging policies for each port in the
port group. A virtual switch must have one port group assigned to it. You can assign additional port groups.
Specify one of the options listed in “Connection Options for vCLI Host Management Commands,” on
page 19 in place of <conn_options>.
n
List port groups currently associated with a virtual switch.
esxcli <conn_options> network vswitch standard portgroup list
The command lists the port group name, associated virtual switch, active clients, and VLAN ID.
n
Add a port group.
esxcli <conn_options> network vswitch standard portgroup add --portgroup-name=<name> --
vswitch-name=vSwitch1
n
Delete one of the existing port groups.
esxcli <conn_options> network vswitch standard portgroup remove --portgroup-name=<name> --
vswitch-name=vSwitch1
