VES-1616FE-55A User’s Guide

MAC Anti-Spoofing Select this to have the VES-1616FE-55A detect whether a MAC address is

connected to more than one port.

Priority Queue

Assignment

IEEE 802.1p defines up to 8 separate traffic types by inserting a tag into a MAC-

layer frame that contains bits to define class of service. Frames without an

explicit priority tag are given the default priority of the ingress port. Use the next

two fields to configure the priority level-to-physical queue mapping.

Priority 7 Typically used for network control traffic such as router configuration messages.

Priority 6 Typically used for voice traffic that is especially sensitive to jitter (jitter is the

variations in delay).

Priority 5 Typically used for video that consumes high bandwidth and is sensitive to jitter.

Priority 4 Typically used for controlled load, latency-sensitive traffic such as SNA

(Systems Network Architecture) transactions.

Priority 3 Typically used for “excellent effort” or better than best effort and would include

important business traffic that can tolerate some delay.

Priority 2 This is for “spare bandwidth”.

Priority 1 This is typically used for non-critical “background” traffic such as bulk transfers

that are allowed but that should not affect other applications and users.

Priority 0 Typically used for best-effort traffic.

Tag Protocol

Identifier

Enter a 4-digit protocol ID which is added together with VLAN (including priority)

tag on traffic. By default, it is 8100 which means Ethernet traffic. This also has

the VES-1616FE-55A accept tagged traffic with the same protocol ID, but drop

tagged traffic with a different protocol ID.

Apply Click Apply to save your changes to the VES-1616FE-55A’s volatile memory.

The VES-1616FE-55A loses these changes if it is turned off or loses power, so

use the Config Save link on the navigation panel to save your changes to the

non-volatile memory when you are done configuring.
