The optional elements of the NSLookup command are described below:

Resolving host host1.
IP address for host drawbridge is 1.1.1.1.
> nslookup 198.4.92.1

NVRAMClear
Description: Clears Nonvolatile Random Access Memory (NVRAM). The current system
configuration is stored in NVRAM.
Note:
A copy of the configuration may also be stored in Flash memory. If you clear NVRAM,
the MAX resets and initializes itself with the configuration it detects in Flash memory. To
return your MAX to its factory default settings, you must first use the FClear command to clear
the configuration in Flash then use NVRAMClear.
Usage: Enter
nvramclear
at the command prompt.

Optional Element
Specifies
-v
The MAX unit displays the details of packets received
from the DNS server responding to the query.
-s dnsServer IPAddr
The MAX unit attempts to resolve the specified
hostname into an IP address by using the specified
dnsServerIpAddr
as the DNS server. If you do not
specify this optional element, the MAX unit uses the
information specified for the Pri DNS and Sec DNS
parameters to determine which server(s) provide the
necessary DNS information.
-r vRouterName
An individual VRouter. If this option is not entered, the
global VRouter will be used.
hostname
