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 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
