DGS-1520 Series Gigabit Ethernet Smart Managed Switch Web UI Reference Guide same physical port. For example, it allows the user to configure an 802.1Q and 802.1v untagged port on the same physical port. To view the following window, click L2 Features > VLAN > 802.1v Protocol VLAN > Protocol VLAN Profile, as shown below: Figure 5-24 Protocol VLAN Profile Window The fields that can be configured are described below: Parameter Profile ID Frame Type Ether Type Description Enter the 802.1v protocol VLAN profile ID here. This value must be between 1 and 16. Select the frame type option here. This function maps packets to protocol-defined VLANs by examining the type octet within the packet header to discover the type of protocol associated with it. Options to choose from are Ethernet 2, SNAP, and LLC. Enter the Ethernet type value for the group here. The protocol value is used to identify a protocol of the frame type specified. The range is from 0x0 to 0xFFFF. Depending on the frame type, the octet string will have one of the following values: • For Ethernet 2, this is a 16-bit (2-octet) hex value. For example, IPv4 is 0800, IPv6 is 86DD, ARP is 0806, etc. • For IEEE802.3 SNAP, this is a 16-bit (2-octet) hex value. • For IEEE802.3 LLC, this is a 2-octet IEEE 802.2 Link Service Access Point (LSAP) pair. The first octet is for Destination Service Access Point (DSAP) and the second octet is for Source. Click the Apply button to accept the changes made.
