3Com Switch 7750 Configuration Guide

102 CHAPTER 11: VLAN CONFIGURATION
■ Currently, only non-Type-A modules, including I/O Modules and Fabric, support
this command.
■ If a protocol-based VLAN has been associated with a module, the VLAN cannot
be removed.
■ If a protocol in a VLAN has been associated with a module, the protocol cannot
be removed from the VLAN.
■ For a given type of packets, if the protocol VLAN bound to a port is different
from the protocol VLAN applied on the module that provides the port, the
board-associated protocol VLAN configuration supersedes the port-associated
protocol VLAN configuration.
Table 55 shows the supported protocol-based VLAN creation on different I/O
Modules.
n
Type A modules include 3C16860, 3C16861, LS81FS24A, 3C16858, 3C16859,
and 32Gbps and 64Gbps Switch Fabrics.
Displaying
Protocol-Based VLAN
Configuration
After the configuration above, you can execute the display command in any view
to display the running status, so as to verify the configuration.
Table 55 Protocol-based VLAN creation on different cards
Description Type A card Non-Type-A card
Create protocol-based VLAN
on specific module in system
view.
Not supported Supported (only for all IP
protocols and subnet IP
protocols).
Create protocol-based VLAN
on specific port in Ethernet
port view.
Supported Supported (exclude all IP
protocols and subnet IP
protocols, AppleTalk protocol,
and the user-defined LLC
template which defines only
one of dsap-id and ssap-id).
