Avaya 580 - Manual (Page 40)

1-16 User Guide for the Avaya P580 and P882 Multiservice Switches, v6.1
Chapter 1
Security
The P580 and P882 support the following security features:
■
Secure Mode—Secure mode restricts management of the switch to
the following secure protocols: HTTPS, SSH, and SNMPv3. For
information on secure mode, see
Chapter 4 , “ Security .”
■
SSHv2—SSH is a protocol for secure remote login and other secure
services. SSH provides a secure service that is similar to Telnet. For
information on SSHv2, see
Chapter 4 , “ Security .”
■
HTTPS Using SSLv3 or TLSv1—SSL and TLS are protocols that
provide data security between application protocols (such as HTTP,
Telnet, NNTP, FTP) and TCP/IP. SSL and TLS are used to transmit
encrypted data over TCP/IP networks, and authenticate sites and
clients with certificates. For information on HTTPS, see
Chapter 4 ,
“ Security .”
■
RADIUS Client Support—RADIUS is a service that authenticates
users when they attempt to log in to a Network Access Device
(NAD) such as an Avaya switch. For information on RADIUS, see
Chapter 4 , “ Security .”
■
SNMPv3. SNMPv3 provides encryption and timeliness checks of
PDUs and authentication of users. For information on SNMPv3, see
Chapter 5 , “ Configuring SNMP .”
■
Enhanced user account security, including maximum number of
login attempts, timeout limit, minimum password length, and
expiration. For information on user account security, see
Chapter 2 ,
“ Setting Up the Switch .”
VLANs
VLANs provide network managers with two significant capabilities:
■
The ability to segment traffic in a flat switched network. This helps
prevent traffic from being forwarded to stations where it is not
needed.
■
The ability to ignore physical switch locations when creating
workgroups. VLANs are logical constructions and can traverse
physical switch boundaries.
