Configuring protocol-based VLANs
11
Assigning a different ID to the default VLAN
As stated above, by default, all ports on a device belong to the default VLAN, which is VLAN 1, until
it is assigned to a port-based VLAN. The default VLAN port membership is always untagged;
however, if you want to use VLAN ID 1 as a configurable VLANs with tagged port members, you can
assign a different VLAN ID as the default VLAN. Enter commands such as the following command.
BigIron RX (config)# default-vlan-id 4000
Syntax: [no] default-vlan-id <vlan-id>
You must specify a VLAN ID that is not already in use. For example, if VLAN 10 exists, do not use
“10” as the new VLAN ID for the default VLAN. Valid VLAN IDs are from 1 – 4089; however, do not
use VLANs 4090 – 4094, which are reserved for control purposes.
Configuring protocol-based VLANs
Once port-based VLANs are created, you can further segment the broadcast domains by creating
protocol-based VLANs, based on Layer 3 protocols. Use the general procedure below for creating
protocol-based VLANs.
1. Create the port-based VLAN that contains the interface that you want to segment using Layer 3
protocols.
BigIron RX (config)# vlan 2
BigIron RX (config-vlan-2)# untag e 1/9 to 1/16
BigIron RX (config-vlan-2)# tagged e 1/1 to 1/8
2. Under the VLAN configuration level, define the Layer 3 protocol you want to use to segment
packets that go through the ports assigned to the port-based VLAN.
BigIron RX (config-vlan-2)# ipv6-proto name Blue
Syntax: [no] ip-proto | ipv6-proto | ipx-proto | atalk-proto | other-proto name
<protocol-vlan-name>
Enter:
•
ip-proto to create a IP protocol VLAN.
•
ipv6-proto to create a IPv6 protocol VLAN.
•
ipx-proto to create a IPX protocol VLAN.
•
atalk-proto to create an Appletalk protocol VLAN.
•
other-proto to create a protocol VLAN for protocols other than an IP protocol, IPv6, IPX, or
Appletalk protocol.
Enter name <vlan-name> if you want to assign a name to the protocol-based VLAN. Enter up to
32 characters for name.
Use the no form of the command to remove the protocol-based VLAN.
3. Assign or exclude specific ports to the protocol-based VLAN
BigIron RX (config-vlan-group-ipv6-proto)# static e 1/1 e 1/24
BigIron RX (config-vlan-group-ipv6-proto)# exclude e 1/2 to 1/4
Syntax: [no] static | exclude ethernet <slot-number>/<port-number> [to
<slot-number>/<port-number> ]
