Configuring IP parameters – Layer 3 Switches
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.
Brocade(config)# interface loopback 2
Brocade(config-lbif-2)# ip address 10.0.0.2/24
Brocade(config-lbif-2)# exit
Brocade(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.
Brocade(config)# interface ethernet 1/4
Brocade(config-if-1/4)# ip address 209.157.22.110/24
Brocade(config-if-1/4)# exit
Brocade(config)# ip telnet source-interface ethernet 1/4
Syntax: [no] ip telnet source-interface ethernet [<slotnum>/]<portnum> | loopback <num> | ve
<num>
The <slotnum> variable is required on chassis devices.
The <portnum> variable is a valid port number.
The <num> variable is a loopback interface or virtual interface number.
TACACS/TACACS+ packets
To specify the lowest-numbered IP address configured on a virtual interface as the device source
for all TACACS/TACACS+ packets, enter commands such as the following.
Brocade(config)# interface ve 1
Brocade(config-vif-1)# ip address 10.0.0.3/24
Brocade(config-vif-1)# exit
Brocade(config)# ip tacacs source-interface ve 1
The commands in this example configure virtual interface 1, assign IP address 10.0.0.3/24 to the
interface, then designate the interface as the source for all TACACS/TACACS+ packets from the
Layer 3 Switch.
Syntax: [no] ip tacacs source-interface ethernet [<slotnum>/]<portnum> | loopback <num> | ve
<num>
The <slotnum> variable is required on chassis devices.
The <portnum> variable is a valid port number.
The <num> variable is a loopback interface or virtual interface number.
RADIUS packets
To specify the lowest-numbered IP address configured on a virtual interface as the device source
for all RADIUS packets, enter commands such as the following.
