Glossary
Dynamic NAT
See
Dynamic PAT
Dynamic Port Address Translation. Dynamic PAT lets multiple outbound sessions appear to originate
from a single IP address. With PAT enabled, the ASA chooses a unique port number from the PAT IP
address for each outbound translation slot (xlate). This feature is valuable when an
enough unique IP addresses for your outbound connections. The global pool addresses always come
first, before a PAT address is used. See also NAT,
E
ECHO
See ping, ICMP. See also
EGP
Exterior Gateway Protocol. Replaced by BGP. The ASA does not support EGP. See also BGP.
EIGRP
Enhanced Interior Gateway Routing Protocol. The ASA does not support EIGRP.
EMBLEM
Enterprise Management BaseLine Embedded Manageability. A syslog format designed to be
consistent with the Cisco IOS system log format and is more compatible with CiscoWorks
management applications.
encryption
Application of a specific algorithm or cipher to data so as to render the data incomprehensible to those
unauthorized to see the information. See also decryption.
ESMTP
Extended SMTP. Extended version of
notification and session delivery. ESMTP is described in RFC 1869, SMTP Service Extensions.
ESP
Encapsulating Security Payload. An
services for establishing a secure tunnel over an insecure network. For more information, refer to
RFCs 2406 and 1827.
F
failover, failover
Failover lets you configure two ASAs so that one will take over operation if the other one fails. The
mode
ASA supports two failover configurations, Active/Active failover and Active/Standby failover. Each
failover configuration has its own method for determining and performing failover. With
Active/Active failover, both units can pass network traffic. Active/Active failover lets you configure
load balancing on your network. Active/Active failover is only available on units running in multiple
context mode. With Active/Standby failover, only one unit passes traffic while the other unit waits in
a standby state. Active/Standby failover is available on units running in either single or multiple
context mode.
