94 CHAPTER 10: VLAN CONFIGURATION
Configuration procedure
c
CAUTION:
■ For the operation of adding a port to the VLAN in the untag way, refer to the
Port Basic Configuration Operation part in this manual.
■ For the same VLAN, it is not allowed to configure the same protocol type and
encapsulation format. Between different VLANs, the same protocol type and
encapsulation format can be configured, but cannot be distributed to the same
port. Even the user-defined template and standard template with the same
encapsulation format cannot be distributed to the same port.
■ If a protocol template has been configured in a VLAN, the VLAN cannot be
removed.
■ If a protocol of a VLAN has been distributed to a port, the VLAN cannot be
removed from the port.
■ If a protocol of a VLAN has been distributed to a port, the protocol cannot be
removed from the VLAN.
Associating a Card with
the Protocol-Based VLAN
c
CAUTION:
■ It is necessary to add those ports that require protocol on the card to the
protocol-based VLAN.
■ Currently, only non-Type-A cards, including I/O Modules and Switch Fabric,
support this command.
■ If a protocol-based VLAN has been associated with a card, the VLAN cannot be
removed.
■ If a protocol in a VLAN has been associated with a card, the protocol cannot be
removed from the VLAN.
Table 47 shows the supported protocol-based VLAN creation on different I/O
Modules.
