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
Using multiple ports in parallel to increase the link speed beyond the limits
of a port and to increase the redundancy fo
r 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.
