mask oui-mask: Specifies the valid length of the OUI address by a mask in the format of H-H-H,
formed by consecutive 1s and 0s, for example, FFFF-0000-0000. To filter the voice device of a specific
vendor, set the mask to FFFF-FF00-0000.
description text: Specifies a string that describes the OUI address. The string is of 1 to 30
case-sensitive characters.
oui: Specifies the OUI address to be removed, in the format of H-H-H, such as 1234-1200-0000. An
OUI address is the logic AND result of mac-address and oui-mask. An OUI address cannot be a
broadcast address, a multicast address, or an address of all 0s or all 1s. You can use the display
voice vlan oui command to display the OUI addresses supported currently.
