Chapter 1 Overview
Features
DNS
The DNS protocol controls the Domain Name System (DNS), a distributed database with which you can
map hostnames to IP addresses. When you configure DNS on your switch, you can substitute the
hostname for the IP address with all IP commands, such as ping, telnet, connect, and related Telnet
support operations.
To keep track of domain names, IP has defined the concept of a domain name server, which holds a cache
(or database) of names mapped to IP addresses. To map domain names to IP addresses, you must first
identify the hostnames, specify the name server that is present on your network, and enable the DNS.

Switch Alarms
The switch software monitors switch conditions on a per-port or a switch basis. If the conditions present
on the switch or a port do not match the set parameters, the switch software triggers an alarm or a system
message. By default, the switch software sends the system messages to a system message logging
facility, or a syslog facility. You can also configure the switch to send Simple Network Management
Protocol (SNMP) traps to an SNMP server. You can configure the switch to trigger an external alarm
device by using the alarm relay.

SDM Templates
If the switch is running the IP services image, you can use SDM templates to optimize system resources
in the switch to support specific features, depending on how the switch is used in the network. The SDM
templates allocate Ternary Content Addressable Memory (TCAM) resources to support different
features. You can use the SDM templates for IP Version 4 (IPv4) and select the default template to
balance system resources or select the layer-2 template to support only Layer 2 features in hardware.
Note Switches running the LAN Base image support only the layer-2 template
The dual IPv4 and IPv6 templates also enable a dual stack environment.

Smartports Macros
Smartports macros provide a convenient way to save and share common configurations. You can use
Smartports macros to enable features and settings based on the location of a switch in the network and
for mass configuration deployments across the network.
