Syntax: [no] decnet-proto [<name>]
To specify a VLAN name, use the name keyword followed by a string. The name keyword and string are the last
arguments in the command. The name can contain blank spaces if you use double quotation marks before and
after the name. The <name> can be up to 16 characters long and can contain blanks.
Configuring an IP Protocol VLAN
You can create an IP protocol VLAN on a ServerIron within a port-based VLAN, when entered at the VLAN Level.
When configuring on a switch, all ports are dynamically allocated to the VLAN. You can modify port membership
by using the static or exclude commands.
If configuring on a Brocade router, ports must be added to the VLAN with the static command. Ports are not
dynamically allocated to IP protocol VLANs.
To assign ports 1, 2, 6 and 8 to an IP protocol VLAN within VLAN 7, enter commands such as the following:
ServerIron(config)#vlan 7
ServerIron(config-vlan-7)#ip-proto
ServerIron(config-vlan-ip-proto)#static e 1 to 2 e 6 e 8
If configuring this on a switch, enter vlan 7 by port at the CONFIG Level versus vlan 7, as shown in the example
above.
Syntax: [no] ip-proto [<name>]
The <name> can be up to 16 characters long and can contain blanks.
An IP protocol and IP sub-net VLAN cannot both be configured to operate on a ServerIron at the same time. This
restriction is also true for IPX and IPX network VLANs.
Configuring an IP Subnet Protocol VLAN
You can create an IP subnet protocol VLAN on a ServerIron within a port-based VLAN, when entered at the VLAN
Level. This allows you to define additional granularity than that of an IP protocol VLAN, by partitioning the
broadcast domains by sub-net. In creating an IP subnet VLAN, an IP address is used as identifier.
When configuring on a switch, all ports are dynamically allocated to the VLAN. You can modify port membership
by using the static or exclude commands.
When configuring on a Brocade router, ports must be added to the VLAN with the static command. Ports are not
dynamically allocated to IP subnet VLANs.
To create an IP sub-net of IP address 192.75.3.0 with permanent port membership of 1 and 2 (module 2), within
VLAN 10, enter commands such as the following:
ServerIron(config)#vlan 10
ServerIron(config-vlan-10)#ip-subnet 192.75.3.0 255.255.255.0
ServerIron(config-vlan-ip-subnet)#static e 1 to 2
If configuring this on a switch, enter vlan 10 by port at the CONFIG Level versus vlan 10, as shown in the
example.
Syntax: [no] ip-subnet <ip-addr> <ip-mask> [<name>]
The <name> can be up to 16 characters long and can contain blanks.
An IP protocol and IP sub-net VLAN cannot both be configured to operate simultaneously on a Brocade switch or
router. This restriction is also true for IPX and IPX Network VLANs.
Configuring an IPX Network VLAN
You can create an IPX network VLAN on a ServerIron within a port-based VLAN, when entered at the VLAN Level.
This command you to define additional granularity than that of the IPX protocol VLAN, by partitioning the
broadcast domains by IPX network number. In creating an IPX network VLAN, an IPX network number is used as
identifier. The frame type must also be specified.
