Switch Management Commands 2002
A out-of-band 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
In order to ensure the security of the switches from intruders, it is strongly
recommended that the out-of-band interface be isolated on a physically
separate network from the in-band ports. This command is only valid for
switches equipped with an out-of-band interface.
Example
The following examples configure the out-of-band interface with an IP
address 131.108.1.27 and subnet mask 255.255.255.0 and the same IP address
with prefix length of 24 bits.
console(config)#interface out-of-band
console(config-if)#ip address 131.108.1.27 255.255.255.0
console(config-if)#ip address 131.108.1.27 /24
ip address-conflict-detect run
Use the ip address-conflict-detect run command in Global Configuration
mode to trigger the switch to run active address conflict detection by sending
gratuitous ARP packets for IPv4 addresses on the switch.
Syntax
