You can configure the Layer 3 switch to always use the lowest-numbered IP address on a specific Ethernet, loopback, or virtual interface
as the source addresses for these packets. When configured, the Layer 3 switch uses the same IP address as the source for all packets
of the specified type, regardless of the ports that actually sends the packets.
Identifying a single source IP address for specified packets provides the following benefits:
• If your server is configured to accept packets only from specific IP addresses, you can use this feature to simplify configuration
of the server by configuring the Brocade device to always send the packets from the same link or source address.
• If you specify a loopback interface as the single source for specified packets, servers can receive the packets regardless of the
states of individual links. Thus, if a link to the 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 specific packets. You can configure a source
interface for one or more of these types of packets separately.
The following sections show the syntax for specifying a single source IP address for specific packet types.
Telnet packets
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.
device(config)# interface loopback 2
device(config-lbif-2)# ip address 10.0.0.2/24
device(config-lbif-2)# exit
device(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 Layer 3 switch.
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 Layer 3 switch.
device(config)# interface ethernet 1/1/4
device(config-if-1/1/4)# ip address 10.157.22.110/24
device(config-if-1/1/4)# exit
device(config)# ip telnet source-interface ethernet 1/1/4
Syntax: [no] ip telnet source-interface { ethernet unit / slot / port | loopback num | management num | ve num }
TACACS/ packets
To specify the lowest-numbered IP address configured on a virtual interface as the device source for all TACACS/ packets,
enter commands such as the following.
device(config)# interface ve 1
device(config-vif-1)# ip address 10.0.0.3/24
device(config-vif-1)# exit
device(config)# ip tacacs source-interface ve 1
