Configuring protocol VLANs with dynamic ports
Syntax: [no] no-dynamic-aging
Enter the no form of the command to disable this feature after it has been enabled.
By default, VLAN membership of dynamically assigned ports will age out after a period of time if no
packets belonging to that protocol or subnet VLAN are received by the CPU.
The output of the show running-config command indicates if the no-dynamic-aging feature is
enabled for a specific protocol or subnet VLAN.
Configuration guidelines for membership
aging of dynamic VLAN ports
• You cannot dynamically add a port to a protocol VLAN if the port has any routing configuration
parameters. For example, the port cannot have a virtual routing interface, IP subnet address,
IPX network address, or AppleTalk network address configured on it.
• Once you dynamically add a port to a protocol VLAN, you cannot configure routing parameters
on the port.
• Dynamic VLAN ports are not required or supported on AppleTalk cable VLANs.
• When protocol VLANs with dynamic ports are configured, the output of the show running-config
command in the Router image will show the “dynamic” keyword. In the Switch image, the
keyword is not shown in the output of the show running-config command.
NOTE
In the Switch image, all the ports are dynamic ports by-default, so the dynamic command does
not appear in the show running-config command output. If you configure the no dynamic
command, it will appear in the output of the show running-config command. Similarly in Router
image, no ports are dynamic by-default, so the no dynamic command does not appear in the
output of the show running-config command. If you configure the dynamic command, it will
appear in the output of the show running-config command.
Configuring an IP, IPX, or AppleTalk Protocol
VLAN with Dynamic Ports
To configure an IP, IPX, or AppleTalk protocol VLAN with dynamic ports, use the following method.
To configure port-based VLAN 10, then configure an IP protocol VLAN within the port-based VLAN
with dynamic ports, enter the following commands such as the following.
Brocade(config)# vlan 10 by port
Brocade(config-vlan-10)# untagged ethernet 1/1 to 1/6
added untagged port ethe 1/1 to 1/6 to port-vlan 30.
Brocade(config-vlan-10)# ip-proto name IP_Prot_VLAN
Brocade(config-vlan-ip-proto)# dynamic
Brocade(config)# write memory
