3.2 Commands for Dynamic VLAN Configuration

Command: dynamic-vlan mac-vlan prefer
Function: Set the MAC based preferred VLAN.
Parameters: None.
Command mode: Global Mode
Default: MAC-based VLAN is preferred.
Usage guide: Configure preference for dynamic-VLAN. The default priority sequence is MAC based VLAN, IP subnet based VLAN, and protocol-based VLAN. Use this command after the IP subnet based VLAN is set to preferred and the user wants to restore to the preferred MAC based VLAN.
Example: Set MAC based VLAN as preferred.

active500EM#config
active500EM(config)#dynamic-vlan mac-vlan prefer

 

Command: dynamic-vlan subnet-vlan prefer
Function: Set IP-subnet-based VLAN preferred.
Parameters: None.
Command mode: Global Mode
Default: MAC-based VLAN is preferred by default.
Usage guide: Configure a preference for dynamic-VLAN on the switch. The default priority sequence is MAC based VLAN, IP subnet based VLAN, and Protocol-based VLAN. This command sets the preference to IP subnet based VLAN.
Example: Set the IP subnet based to VLAN as preferred.

active500EM#config
active500EM(config)#dynamic-vlan subnet-vlan prefer

 

Command: mac-vlan mac <mac-addrss> vlan <vlan-id> priority <priority-id>
no mac-vlan {mac <mac-addrss>|all}
Function: Associate a MAC address to a VLAN. Specify the MAC address to be joined to a specified VLAN. The no command deletes the association.
Parameters:

• <mac-addr>: the MAC address which is shown in the form of XX-XX-XX-XX-XX-XX.
• <vlan-id>: the ID of the VLAN with a valid range of 1 to 4094
• <priority-id>: the level of priority used in the VLAN tag. The valid range is 0 to 7.
• all: refers to all the MAC addresses.

Command mode: Global Mode
Default: None.
Usage guide: This command allows the user to add a specified MAC address to a specified VLAN. If a VLAN with no label on the data packet enters from the switch port from the specified MAC address, a specified VLAN ID will be assigned. The VLAN associated with the data packet is the same regardless of the port of origin. The command does not update the VLAN label data packet.
Example: Add a MAC address of 00-03-0f-11-22-33 to VLAN 100.

active500EM#config
active500EM(config)#mac-vlan mac 00-03-0f-11-22-33 vlan 100 priority 0

 

Command: mac-vlan vlan <vlan-id>
no mac-vlan vlan <vlan-id>
Function: Configure the specified VLAN to MAC VLAN. The no command cancels the MAC VLAN configuration of this VLAN.
Parameters:

• <vlan-id>: the number of the specified VLAN

Command mode: Global Mode
Default: No MAC VLAN.
Usage guide: Set the specified VLAN for the MAC VLAN.
Example: Set VLAN100 for the MAC VLAN.

active500EM#config
active500EM(config)#mac-vlan vlan 100

 

Command: protocol-vlan mode {ethernetii etype <etype-id>| llc {dsap <dsap-id> ssap <ssap-id>} | snap etype <etype-id>} vlan <vlan-id> [priority <priority-id>] no protocol-vlan {mode {ethernetii etype <etype-id> | llc {dsap <dsap-id> ssap <ssap-id>} | snap etype <etype-id>} | all}
Function: Specify the protocol correspondence with a specified VLAN. The no command deletes all protocol correspondence with the VLAN.
Parameters:

• mode: configuration options are ethernetii, llc, and snap. The encapsulate type of the ethernetii is EthernetII.
• <etype-id>: the type of the packet protocol. The valid range is from 1536 to 65535.
• <llc>: llc encapsulate format.
• <dsap-id>: access point of the destination service. The valid range is from 0 to 255.
• <ssap-id>: access point of the source service. The valid range is from 0 to 255.
• snap: SNAP format.
• <etype-id>: the type of the packet protocol. The valid range is from 1536 to 65535.
• <vlan-id>: ID of the VLAN. The valid range is from 1 to 4094.
• <priority-id>: Priority of VLAN. The valid range is from 0 to 7.
• all: indicates all the encapsulated protocols.

Command mode: Global Mode
Default: No protocol is joined to the VLAN.
Usage guide: This command adds a specified protocol to a specified VLAN. Any packet from the specified protocol entering through the switch port will be assigned to the specified VLAN ID and enter the specified VLAN regardless of which port the packets enter. The command will not interfere with data packets that have a VLAN label. Configure ARP protocol in conjunction with the IP protocol to avoid affecting another application.
Example: Assign the IP protocol data packet encapsulated by EthernetII to VLAN200.
