Black Box®LB1350A/LB1351A
The broadcast protection indicates the relative amount of broadcast traffic that will be forwarded by the Black Box® LB1351A, starting at 25% maximum and down to 3% minimum. Default value is 25%.
The DSCP codes are represented as a series of 8 bytes, corresponding to 64 bits. These bits correspond, in turn, to 64 different DSCP codes. If you wish, for instance, to set code 45 as high priority, then bit 45 in this series needs to be set to ‘1’ (this is done though the control menus, described later). Default values are all 0s (meaning all codes are low priority).
The user priority codes are used in conjunction with the 802.1p based priority scheme. For example, if a tagged frame arrives with a priority code of 6, the Black Box® LB1351A will look priority code 6 to see if it is set as high or low priority and handle the frame accordingly. Default values are low priority for codes
