DCS-3950 series Ethernet switch manual
Command: protocol-vlan enable
no protocol-vlan enable
Function: Enable the protocol VLAN. If no is put in front of the command, the command
will be disabled.
Command mode: Global Mode
Default: Protocol VLAN is disabled by default.
Usage Guide: Protocol VLAN should be enabled before executing the following
commands.
Example: Enable the protocol VLAN. Switch #config
Switch (Config)#protocol-vlan enable
9.4.3.2 protocol-vlan mode
Command: protocol-vlan mode {ethernetii etype <etype-id>|llc {dsap <dasp-id>
ssap <ssap-id>}|snap etype <etype-id>} vlan <vlan-id> [priority
<priority-id>]
no protocol-vlan {mode {ethernetii etype <etype-id>|llc {dsap <dasp-id>
ssap <ssap-id>}|snap etype <etype-id>}|all}
Function: Add the correspondence between the protocol and the VLAN namely specify
the protocol to join specified VLAN. The ‘no’ form of this command deletes all or the
correspondence
Parameters: Mode is the encapsulate type of the configuration which is ethernetii,llc
andsnap;the encapsulate type of the ethernetii is EthernetII;etype-id is the type of the
packet protocol, with a valid range of 1536~65535;llc is LLC encapsulate format;dasp-id is
the access point of the destination service, the valid range is 0~255;aasp-id is the access
point of the source service with a valid range of 0~255;snap is SNAP encapsulate
format;etype-id is the type of the packet protocol, the valid range is 1536~65535;vlan-id is
the ID of VLAN, the valid range is 1~4094;all indicates all the encapsulate protocols.
Command mode: Global Mode
Default: No protocol joined the VLAN by default
Usage Guide: This command is used to add specific protocols into the VLAN. If a packet
of specified protocols without VLAN tags is received by the switch, it will be matched to the
specified VLAN ID, and thus forwarded to that VLAN. The VLAN tag will be the same for
those packets regardless from which port the packets are received. When this command
is set, packets already attached with VLAN tags will not be affected. The ARP protocol is
suggested to be configured if the IP protocol has been configured. Otherwise, some
application may be influenced by the configuration.
Example: Assign the IP protocol data packet encapsulated by the EthernetII to VLAN200,
QoS precedence is 0.
Switch #config
Switch (Config)#protocol-vlan enable
Switch (Config)#protocol-vlan mode ethernetii etype 2048 vlan 200 priority 0
Switch (Config)#protocol-vlan mode ethernetii etype 2054 vlan 200 priority 0
