14 DNS Resolver and RMON

Introduction
This chapter describes commands related to the Domain Name Server (DNS) resolver and
remote network monitoring (RMON) feature in the switch. This chapter also describes how to
configure router port MAC addresses with the chngmac command.
The commands for these features are available from the Networking submenu, which is
described in Chapter 25, “IP Routing.”

The Names command takes you to the Names submenu. The one command in this menu, res,

name to an IP address or until it fails to find the name.
