Accessing Alteon

• Using an SSH connection to securely log into another computer over a network—The
SSH (Secure Shell) protocol enables you to securely log into another computer over a network
to execute commands remotely. As a secure alternative to using Telnet to manage the Alteon
configuration, SSH ensures that all data sent over the network is encrypted and secure. For
more information, see Secure Shell and Secure Copy, page 70
.
For more information on CLI menus and commands, see the Alteon Application Switch Operating
System Command Reference.
Using SNMP
Alteon provides Simple Network Management Protocol (SNMP) v1.0 and SNMP v3.0 support for
access through any network management software, such as APSolute Vision or HP-OpenView.
SNMP v1.0
To access the SNMP agent, the read and write community strings on the SNMP manager should be
configured to match those on Alteon. The default read community string on Alteon is set to public,
and the default write community string is set to private.
Caution: Leaving the default community strings enabled on Alteon presents a security risk. You can
change the community strings as follows:
• Read community string—
/cfg/sys/ssnmp/rcomm <string>
• Write community string—/cfg/sys/ssnmp/wcomm <string>
The SNMP manager should reach the management interface (management port) or any one of the
Alteon IP interfaces.
SNMP v3.0
SNMPv3 is an enhanced version of SNMP, approved by the Internet Engineering Steering Group in
March, 2002. SNMP v3.0 contains additional security and authentication features that provide data
origin authentication, data integrity checks, timeliness indicators, and encryption to protect against
threats such as masquerade, modification of information, message stream modification, and
disclosure.
SNMPv3 ensures that the client can use SNMP v3 to query the MIBs, mainly for security purposes.
To access the SNMP v3.0 menu, enter the following command in the CLI:
For more information on SNMP MIBs and the commands used to configure SNMP on Alteon, see the
Alteon Application Switch Operating System Command Reference.
Default Configuration
Alteon has two default users: adminmd5, which uses MD5 authentication, and adminsha, which
uses SHA authentication.
Both these users have access to all the MIBs supported by Alteon. By default, the passwords for
these users are adminmd5 and adminsha, respectively.
