Configuring IP parameters – Layer 3 Switches
The <portnum> variable is a valid port number.
The <num> variable is a loopback interface or virtual interface number.
The default is the lowest-numbered IP or IPv6 address configured on the port through which the
packet is sent. The address therefore changes, by default, depending on the port.
SNTP packets
To specify the lowest-numbered IP address configured on a virtual interface as the device source
for all SNTP packets, enter commands such as the following.
Brocade(config)# interface ve 1
Brocade(config-vif-1)# ip address 10.0.0.5/24
Brocade(config-vif-1)# exit
Brocade(config)# ip sntp source-interface ve 1
The commands in this example configure virtual interface 1, assign IP address 10.0.0.5/24 to the
interface, then designate the interface's address as the source address for all SNTP packets.
Syntax: [no] ip sntp 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.
The default is the lowest-numbered IP or IPv6 address configured on the port through which the
packet is sent. The address therefore changes, by default, depending on the port.
SSH packets
NOTE
When you specify a single SSH source, you can use only that source address to establish SSH
management sessions with the Brocade device.
To specify the numerically lowest IP address configured on a loopback interface as the device
source for all SSH packets, enter commands such as a 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 ssh 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 SSH packets from the Layer 3
Switch.
Syntax: [no] ip ssh source-interface ethernet [<slotnum>/]<portnum> | loopback <num> | ve
<num>
The <slotnum> parameter is required on chassis devices.
The <portnum> parameter is a valid port number.
The <num> parameter is a loopback interface or virtual interface number.
