Configuring the Host Name

Example

Switch# show interfaces fastethernet 0 FastEthernet0 is up, line protocol is up

Hardware is AmdFE, address is 0000.1644.28ea (bia 0000.1644.28ea) Internet address is 172.20.54.152/24

MTU 1500 bytes, BW 10000 Kbit, DLY 1000 usec, reliability 255/255, txload 1/255, rxload 1/255

Encapsulation ARPA, loopback not set Keepalive set (10 sec)

Half-duplex, 10Mb/s, 100BaseTX/FX ARP type: ARPA, ARP Timeout 04:00:00

Last input 00:00:00, output 00:00:00, output hang never Last clearing of "show interface" counters never

Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 0

Queueing strategy: fifo Output queue :0/40 (size/max)

5 minute input rate 3000 bits/sec, 6 packets/sec

5 minute output rate 1000 bits/sec, 3 packets/sec

36263 packets input, 3428728 bytes

Received 17979 broadcasts, 0 runts, 0 giants, 0 throttles 0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored

0 watchdog

0 input packets with dribble condition detected

20363 packets output, 4279598 bytes, 0 underruns

0 output errors, 8 collisions, 0 interface resets

0 babbles, 0 late collision, 72 deferred

0 lost carrier, 0 no carrier

0 output buffer failures, 0 output buffers swapped out

Displaying the Operating Configurations

You can display the configuration file when you are in privileged EXEC (enable) mode.

•To see the current operating configuration, enter the following command at the enable prompt:

Switch# more system:running-config

•To see the configuration saved in NVRAM, enter the following command:

Switch# more nvram:startup-config

If you made changes to the configuration, but did not yet write the changes to NVRAM, the contents of the running-config file will differ from the contents of the startup-config file.

Configuring the Host Name

In addition to passwords and an IP address, your initial configuration should include the host name to make it easier to configure and troubleshoot the Cisco ONS 15530. To configure the host name, perform the following steps:

	Command	Purpose
Step 1
Step 1	Switch# configure terminal	Enters global configuration mode.
	Switch(config)#
Step 2
Step 2	Switch(config)# hostname name	Specifies a system name.
