trunking methods for transmitting VLAN traffic over 100BASE-T and Gigabit
Ethernet ports.
The GigaStack GBIC also supports both trunking methods. When you are
configuring a cascaded stack of Catalyst 3500 XL switches using the GigaStack
GBIC and want to include more than one VLAN in the stack, be sure to configure
all of the GigaStack GBIC interfaces as trunk ports by using the switchport mode
trunk interface configuration command and to use the same encapsulation
method by using the switchport encapsulation {isl | dot1q} interface
configuration command. For more information on these commands, refer to the
Catalyst 2900 Series XL and Catalyst 3500 Series XL Command Reference.
Trunking is not supported on all switches and modules. For the list of products
that support trunking, refer to the release notes.
