Cancelling An Outbound Telnet Session; Configuring An Interface As The Source For All Tftp Packets - Dell PowerConnect B-RX Configuration Manual

•
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.
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 routing interface as the device's
source for all Telnet packets, enter commands such as the following.
BigIron RX(config)# int loopback 2
BigIron RX(config-lbif-2)# ip address 10.0.0.2/24
BigIron RX(config-lbif-2)# exit
BigIron RX(config)# ip telnet source-interface loopback 2
The commands configure loopback interface 2, assign IP address 10.0.0.2/24 to it, then designate
it 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.
BigIron RX(config)# interface ethernet 1/4
BigIron RX(config-if-e10000-1/4)# ip address 209.157.22.110/24
BigIron RX(config-if-e10000-1/4)# exit
BigIron RX(config)# ip telnet source-interface ethernet 1/4

Cancelling an outbound Telnet session

If you want to cancel a Telnet session from the console to a remote Telnet server (for example, if the
connection is frozen), you can terminate the Telnet session by doing the following.
1. At the console, press Ctrl-^ (Ctrl-Shift-6).
2. Press the X key to terminate the Telnet session.
Pressing Ctrl-^ twice in a row causes a single Ctrl-^ character to be sent to the Telnet server. After
you press Ctrl-^, pressing any key other than X or Ctrl-^ returns you to the Telnet session.

Configuring an interface as the source for all TFTP packets

You can configure the device to use the lowest-numbered IP address configured on a loopback
interface, virtual routing interface, or Ethernet port as the source for all TFTP packets it sends. The
software uses the lowest-numbered IP address configured on the interface as the source IP
address for the packets.

Configuring an interface as the source for all TFTP packets

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.
