Configuring basic system parameters
The first message (the one on the bottom) indicates that user “dg” logged in to the CLI User EXEC
level on October 15 at 5:38 PM and 3 seconds (Oct 15 17:38:03). The same user logged into the
Privileged EXEC level four seconds later.
The user remained in the Privileged EXEC mode until 5:59 PM and 22 seconds. (The user could
have used the CONFIG modes as well. Once you access the Privileged EXEC level, no further
authentication is required to access the CONFIG levels.) At 6:01 PM and 11 seconds, the user
ended the CLI session.
Disabling the Syslog messages and traps
Logging of CLI access is enabled by default. If you want to disable the logging, enter the following
commands.
TurboIron(config)#no logging enable user-login
TurboIron(config)#write memory
TurboIron(config)#end
TurboIron#reload
Syntax: [no] logging enable user-login
Configuring an interface as the source for all Telnet packets
You can designate the lowest-numbered IP address configured on an interface as the source IP
address for all Telnet packets from the device. Identifying a single source IP address for Telnet
packets provides the following benefits:
• If your Telnet server is configured to accept packets only from specific links or IP addresses,
you can use this feature to simplify configuration of the Telnet server by configuring the device
to always send the Telnet packets from the same link or source address.
• If you specify a loopback interface as the single source for Telnet packets, Telnet servers can
receive the packets regardless of the states of individual links. Thus, if a link to the Telnet
server becomes unavailable but the client or server can be reached through another link, the
client or server still receives the packets, and the packets still have the source IP address of
the loopback interface.
The software contains separate CLI commands for specifying the source interface for Telnet,
TACACS/TACACS+, and RADIUS packets. You can configure a source interface for one or more of
these types of packets.
To specify an interface as the source for all Telnet packets from the device, use the following CLI
method. The software uses the lowest-numbered IP address configured on the interface as the
source IP address for Telnet packets originated by the device.
To specify the lowest-numbered IP address configured on a virtual interface as the device source
for all Telnet packets, enter commands such as the following.
TurboIron(config)#int loopback 2
TurboIron(config-lbif-2)#ip address 10.0.0.2/24
TurboIron(config-lbif-2)#exit
TurboIron(config)#ip telnet source-interface loopback 2
The commands in this example configure loopback interface 2, assign IP address 10.0.0.2/24 to
the interface, then designate the interface as the source for all Telnet packets from the device.
Syntax: ip telnet source-interface ethernet <portnum> | loopback <num> | ve <num>
The following commands configure an IP interface on an Ethernet port and designate the address
port as the source for all Telnet packets from the device.
