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
Using 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 the switch device.
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 detect loss of continuity in a network by
transmitting CCM frames to a peer MEP.
