Switch Management Commands 1984
Command Mode
Interface Configuration (VLAN, Loopback) mode
User Guidelines
This command also implicitly enables the VLAN or loopback interface for
routing (i.e. as if the user had issued the ‘routing’ interface command). By
default, configuring an IP address on a VLAN enables in-band management
for interfaces configured with that VLAN. Setting up an IP address on VLAN
1 enables switch management on all in-band interfaces except for those where
VLAN 1 is specifically excluded.
The ip address none command clears the currently assigned IPv4 address and
sets the IP address configuration method to none. The no ip address
command clears the currently assigned IPv4 address and sets the IP address
configuration method to the default (whatever the default is).
Use the show ip interface {management|vlan <vlanid>} command to
display the configured IP addresses.
A physical or loopback interface must be made a member of the VLAN in
order for the address configuration to be bound to an interface.
A VLAN interface configured for DHCP address assignment will send the
following text string in DHCP Option 60 of the DHCPDISCOVER message
to assist the DHCP server in identification of the switch: "DellEMC;<switch
model>;<firmware version>;<serial number>". The left and right angle
brackets and quotation marks are not sent. An example option 60 string
might be: DellEMC;N2128PX-ON;6.5.2.0;TW06G93K282986CR0040
IP addresses assigned to Ethernet interfaces support up to 31 bit subnet
masks. IP addresses assigned to loopback ports support a full 32 bit subnet
mask.
Example
The following example defines the IP address and subnet mask for VLAN 15
and enables the VLAN for routing.
console(config)#interface vlan 15
console(config-if-vlan15)#ip address 192.168.10.10 255.255.255.0
