xStack® DGS-3600 Series Layer 3 Managed Gigabit Ethernet Switch The following parameters can be configured Parameter Description MAC Address VLAN Name Specifies the MAC Address of the entry you wish to Add or Find. Specifies the VLAN to be associated with the MAC Address. To delete a specific entry click the corresponding Protocol VLAN button, to clear all entries click Delete All. The Switch incorporates the idea of protocol-based VLANs. This standard, defined by the IEEE 802.1v standard maps packets to protocol-defined VLANs by examining the type octet within the packet header to discover the type of protocol associated with it. After assessing the protocol, the Switch will forward the packets to all ports within the protocol-assigned VLAN. This feature will benefit the administrator by better balancing load sharing and enhancing traffic classification. The Switch supports fourteen predefined protocols for configuration. The user can define a protocol by properly configuring the protocol value. The following is a list of protocol values for some common protocols.

Protocol VLAN and the corresponding protocol value The following windows are used to create Protocol VLAN groups on the switch. The purpose of these Protocol VLAN groups is to identify ingress untagged packets and quickly and accurately send them to their destination. Ingress untagged packets can be identified by a protocol value in the packet header, which has been stated here by the user. Once identified, these packets can be tagged with the appropriate tags for VLAN and priority and then relayed to their destination. To achieve this goal, users must first properly set the type of protocol, along with the identifying value located in the packet header and apply it to a protocol group, which is identified by an ID number. Once the group has been created and configured, then users must add it to a port or set of ports using the Protocol VLAN Port Settings window, and configure the appropriate VLAN and priority tags for these untagged packets. When these actions are completed and saved to the switch, then the ingress and untagged packets can be appropriately dealt with and forwarded through the switch.
