User Names,
Passwords and
SNMP Community
Names All user names, passwords, and SNMP community names are
transferred over the network as plain-text. This means that someone
capable of monitoring the network traffic can determine the user names
and passwords required to access the Management Card. Any similar
device with Telnet server, Web server, or
SNMPv1 agent will have the
same constraints due to the limitations in the protocols themselves.
Each of the interfaces and access methods is described in the following
table.
