AMS
AMS is an acronym for Auto Media Select. AMS is used for dual media ports (ports supporting both
copper (cu) and fiber (SFP) cables. AMS automatically determines if a 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 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.
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.
CCM
CCM is an acronym for Continuity Check Message. It is a OAM frame transmitted from a MEP to it's
peer MEP and used to implement CC functionality.
CDP
CDP is an acronym for Cisco Discovery Protocol.
DEI
DEI is an acronym for Drop Eligible Indicator. It is a 1-bit field in the VLAN tag.
