4.10.4.11 MAC Addresses Deny List
The MAC Addresses Deny List menu enables viewing and editing the MAC
Addresses Deny List. This list is used to deny services to MAC Addresses behind
SUs. Uplink frames whose source MAC address matches any of the entries in the
list and downlink frames whose destination MAC address matches any of the
entries in the list will be discarded.
The MAC Addresses Deny List menu also enables viewing and resetting the MAC
Addresses Deny List Counters, which display for each of the entries in the list the
number of frames that were discarded because they match the entry,
accumulated since the last reset.
