Configuring Another Protocol VLAN

You can create another protocol VLAN on the system. All ports of the switch are by default dynamically assigned

to the newly created VLAN. VLAN Membership can be modified using the dynamic, static, or exclude

commands.

You can use this option to define a protocol-based VLAN for protocols that are not specified as supported protocol

VLANs on a switch or router, or do not require dedicated, separate broadcast domains.

On a 16 port ServerIron, ports 13 through 16 represent protocols Decnet and AppleTalk. You do not need to

separate traffic by protocol into separate broadcast domains. Instead, create an Other Protocol VLAN with just

those ports as members:

ServerIron(config)#other-proto

ServerIron(config-other-proto)#static e13 to 16

ServerIron(config-other-proto)#exclude e1 to 12

ServerIron(config-other-proto)#exit

Syntax: [no] other-proto [<name>]

Dual-Mode VLAN Ports

Configuring a tagged port as dual-mode allows it to accept and transmit both tagged and untagged traffic

simultaneously. A dual-mode port accepts and transmits frames belonging to VLANs configured for the port, as

well as frames belonging to the default VLAN (untagged traffic).

For example, in Figure 2.1, port 2/11 is a dual-mode port belonging to VLAN 20. Traffic for VLAN 20, as well as

traffic for the default VLAN, flows from a hub to this port. The dual-mode feature allows traffic for VLAN 20 and

untagged traffic to go through the port at the same time.

Figure 2.1 Dual-mode VLAN port example

To enable the dual-mode feature on port 2/11 in Figure 2.1 enter the following commands:

ServerIron(config)#vlan 20

ServerIron(config-vlan-20)#tagged e 2/11

ServerIron(config-vlan-20)#tagged e 2/9

ServerIron(config-vlan-20)#int e 2/11
