Chapter 4 Administering the Switch

Information About Administering the Switch

DNS

The DNS protocol controls the Domain Name System (DNS), which is a distributed database for

mapping 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.

IP defines a hierarchical naming scheme that allows a device to be identified by its location or domain.

Domain names use period delimiters. For example, Cisco Systems is a commercial organization that IP

identifies by a com domain name, so its domain name is cisco.com. A specific device in this domain, for

example, the File Transfer Protocol (FTP) system is identified as ftp.cisco.com.

To track 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.

MAC Address Table

The MAC address table contains address information that the switch uses to forward traffic between

ports. All MAC addresses in the address table are associated with one or more ports. The address table

includes these types of addresses:

• Dynamic address: a source MAC address that the switch learns and then ages when it is not in use.

• Static address: a manually entered unicast address that does not age and that is not lost when the

switch resets.

The address table lists the destination MAC address, the associated VLAN ID, and port number

associated with the address and the type (static or dynamic).

Building the Address Table

With multiple MAC addresses supported on all ports, you can connect any port on the switch to

individual workstations, repeaters, switches, routers, or other network devices. The switch provides

dynamic addressing by learning the source address of packets it receives on each port and adding the

address and its associated port number to the address table. As stations are added or removed from the

network, the switch updates the address table, adding new dynamic addresses and aging out those that

are not in use.

The aging interval is globally configured. However, the switch maintains an address table for each

VLAN, and STP can accelerate the aging interval on a per-VLAN basis.

The switch sends packets between any combination of ports, based on the destination address of the

received packet. Using the MAC address table, the switch forwards the packet only to the port associated

with the destination address. If the destination address is on the port that sent the packet, the packet is

filtered and not forwarded. The switch always uses the store-and-forward method: complete packets are

stored and checked for errors before transmission.

MAC Addresses and VLANs

All addresses are associated with a VLAN. An address can exist in more than one VLAN and have

different destinations in each. Unicast addresses, for example, could be forwarded to port 1 in VLAN 1

and ports 1, 9, and 10 in VLAN 5.
