Deleting a VLAN

 When you update the VSIDB using the following command:
RS 8264CS# virt evb update vsidb <number>
When the management port link status changes from down to up

When a VM gets associated, the corresponding VLAN is dynamically created on
the switch port if the VLAN does not already exist.
VLANs that are dynamically created will be automatically removed from the
switch port when there are no VMs using that VLAN on the port.
Dynamic VLAN information will not be displayed in the running configuration.
However, the VLAN, port, and STP commands display the dynamic VLAN
information with a "*".
If you configure any Layer 2/Layer 3 features on dynamically created VLANs, the
VLAN information is displayed in the running configuration.
If you delete a VLAN that has a VM associated with it, you will see a warning
message similar to the following:
Warning: Vlan 10 is used by VM and can't be removed.
The VMs will not get disassociated.
If a VM is associated with a port, and you remove this port from a VLAN, you will
see a warning message similar to the following:
Warning: Port 23 in Vlan 10 is used by VM and can't be removed.
The VMs will not get disassociated.
Reflective Relay (RR) is an operation where the switch forwards a frame back to the
port on which it arrived if the destination MAC address is on the same port. When
an EVB profile is configured on a port, RR is automatically enabled on the port
after capability exchange with the peer, using the IEEE802.1QBG protocol. This is
the usual mode of operation.
When the switch interoperates with devices that do not support IEEE 802.1QBG
protocols, RR can be manually configured using the following command:
RS 8264CS(config-if)# reflective-relay force
Manual RR and EVB profile cannot be configured on a port at the same time.
If a port belongs to an isolated VLAN, Manual RR will not work for the respective
port.
