then that policy can be associated with a group of ports under the "Ports" web page. There are
number of parameters that can be configured with an ACE. Read the web page help text to get
further information for each of them. The maximum number of ACEs is 64.
ACL|Ports : The ACL Port configuration is used to assign a Policy ID to an ingress port. This is
useful to group ports to obey the same traffic rules. Traffic Policy is created under the "Access
Control List". You can you also set up specific traffic properties (Action / Rate Limiter / Port copy,
etc) for each ingress port. They will though only apply if the frame gets past the ACE matching
without getting matched. In that case a counter associated with that port is incremented. See the
web page help text for each specific port property.
ACL|Rate Limiters : On this page, you can configure the rate limiters. There can be 15 different
rate limiters, each ranging from 1 to 1024K packets per second. Under "Ports" and "Access
Control List", you can assign a Rate Limiter ID to the ACE(s) or ingress port(s).
AES
AES is an acronym for A dvanced E ncryption S tandard. The encryption key protocol is applied in
802.1x standard to improve WLAN security. It is an encryption standard by the U.S. government,
which will replace DES and 3DES. AES has a fixed block size of 128 bits and a key size of 128,
192, or 256 bits.
AMS
AMS is an acronym for A uto M edia S elect. AMS is used for dual media ports (ports supporting
both copper (cu) and fiber (SFP) cables. AMS automatically determines if an SFP or a CU cable
is inserted and switches to the corresponding media. If both SFP and cu cables are inserted, the
port will select the prefered media.
APS
APS is an acronym for A utomatic P rotection S witching. This protocol is used to secure switching
that is done bidirectional in both ends of a protection group, as defined in G.8031.
