Configuring Ports
CLI Command To configure switch ports using the CLI, use the following CLI command:
(configure)# set port <options>
* Note: See the examples later in this section for recommendations on
how to set particular trunk port connections.
* Note: See “VLAN Operation” in Chapter6 for more information on
creating VLANs.
Automatic VLAN Creation
Automatic VLAN creation is done by enabling the Automatic VLAN
Creation parameter on an individual port under the ‘Module & Ports >
Configuration > Switch Ports > name menu. With this parameter enabled,
the port will automatically create a VLAN each time it receives a frame
from an unknown VLAN ID in received IEEE 802.1Q and Multi-Layer
tagged frames.
* Note: The automatic VLAN creation feature does not create entri es in
3Com Mapping Tables.
When a VLAN is created automatically the VLAN name and VLAN ID a re
derived from the received tagged frame. The VLAN name will be crea ted as
*autoVlan <VLAN ID>. The VLAN ID will be identical to the VLAN ID of
the received tagged frame. As with all VLANs, the VLAN name may be
modified to something more descriptive.
Tabl e 8-9 shows the Avaya P580 and P882 Multiservice switch VLAN
table. The VLANs Default and Discard are permanent VLANs assigned to
every switch. VLAN Net90 is a manually created VLAN, while VLAN
*autoVlan1001 was created automatically by software.
Tabl e 8-8 describes the VLAN Binding field options.
Automatic VLAN
Creation Enable (Disable if using VTP Snooping) - Causes the
switch to learn new VLAN IDs that arrive at the port, and
then bind the port to these VLANs.
VTP Snooping Enable - Causes the switch to update its VLANs as they
are created, deleted, or changed on the Catalyst.
