Step 3: Test the SNMP configuration using your favorite SNMP management tool
The following tests have been done using NET-SNMP with SNMPv2:
C:\>snmpwalk -v 2c -c read 10.0.1.70 system
SNMPv2-MIB::sysDescr.0 = STRING: FSC SwitchBlade
SNMPv2-MIB::sysObjectID.0 = OID: SNMPv2-SMI::enterprises.231
DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (26581200) 3 days, 1:50:12.00
SNMPv2-MIB::sysContact.0 = STRING: Test123
SNMPv2-MIB::sysName.0 = STRING: bx6-sb9-a
SNMPv2-MIB::sysLocation.0 = STRING: Team PCT
SNMPv2-MIB::sysServices.0 = INTEGER: 6
SNMPv2-MIB::sysORLastChange.0 = Timeticks: (500) 0:00:05.00
C:\>snmpget -v 2c -c write 10.0.1.70 sysContact.0
SNMPv2-MIB::sysContact.0 = STRING: Test123
C:\>snmpset -v 2c -c write 10.0.1.70 sysContact.0 s "SNMP v2c Write Test"
SNMPv2-MIB::sysContact.0 = STRING: SNMP v2c Write Test
C:\>snmpget -v 2c -c write 10.0.1.70 sysContact.0
SNMPv2-MIB::sysContact.0 = STRING: SNMP v2c Write Test
C:\>snmpset -v 2c -c read 10.0.1.70 sysContact.0 s "SNMP v2c Read-Only Test"
Error in packet.
Reason: noAccess
Failed object: SNMPv2-MIB::sysContact.0
4.3 Remote Console Access
4.3.1 Introduction
In addition to the web interface, the SB9 supports three methods of accessing the command line interface:
• Console access using console redirection of the management blade
• Telnet access
• SSH access
During the initial setup, console redirection is the only possible way of accessing the switch. Access using telnet or SSH will
subsequently be more convenient.
4.3.2 Recommended Solution
Telnet is an unencrypted protocol, which means that not only the data but also the password is sent unencrypted over IP. For
this reason most enterprise customers prefer not to use telnet. SSH encrypts not only the password but also the entire data
traffic, and is the preferred protocol for remote console access.
We recommend you to enable SSH and disable telnet access to the switch.
4.3.3 Configuration of SSH
The following steps are necessary to enable SSH and disable telnet.
• Step 1: Configure the SB9
• Step 2: Test the login
Step 1: Configure the SB9
! SB9 ssh configuration
!
! Enable ssh
ip ssh
! Set the procol version 2
ip ssh protocol 2
! Disable telnet
line vty
no sessions
exit
Step 2: Test the login
One of the popular SSH clients is “putty” which is distributed under license from MIT.
C:\> putty bx6-sb9-b
login as: test-ro
test-ro @bx6-sb9-b's password:
(bx6-sb9-b) >
