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, “Secu rity.”
■SSHv2—SSH is a protocol for secure remote login and other secure
services. SSH provides a secu re 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 Chapter4,
“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 fla t s witched 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.
