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: Under this page you can configure the rate limiters. There
can be 15 different rate limiters, each ranging from 1-1024K packets per seconds.
Under "Ports" and "Access Control List" web-pages you can assign a Rate
Limiter ID to the ACE(s) or ingress port(s).
AES
AES is an acronym for Advanced Encryption Standard. The encryption key
protocol is applied in 802.1i 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.
APS
APS is an acronym for Automatic Protection Switching. This protocol is used to
secure that switching is done bidirectional in the two ends of a protection group,
as defined in G.8031.
Aggregation
Use multiple ports in parallel to increase the link speed beyond the limits of a
port and to increase the redundancy for higher availability.
(Also Port Aggregation, Link Aggregation).
ARP
ARP is an acronym for Address Resolution Protocol. It is a protocol that used to
convert an
IP address into a physical address, such as an Ethernet address. ARP
allows a host to communicate with other hosts when only the Internet address of
its neighbors is known. Before using IP, the host sends a broadcast ARP request
containing the Internet address of the desired destination system.
ARP Inspection
ARP Inspection is a secure feature. Several types of attacks can be launched
against a host or devices connected to Layer 2 networks by "poisoning" the ARP
caches. This feature is used to block such attacks. Only valid ARP requests and
responses can go through DUT.
Auto-Negotiation
Auto-negotiation is the process where two different devices establish the mode
of operation and the speed settings that can be shared by those devices for a link.
C
CC
CC is an acronym for Continuity Check. It is a MEP functionality that is able to
