Untuk mendapatkan informasi konfigurasi switch, sebelumnya kamu perlu masuk ke priviledeged
EXEC. kemudian, gunaka perintah show, untuk melihat apa saja yang dapat dilihat, tambahkan tanda ? dibelakang perintah show.

Untuk melihat konfigurasi yang akan dijalankan saat switch pertama kali hidup, gunakan perintah show startup-config.
Switch#show startup-config
startup-config is not present
Karena tidak ada konfigurasi yang disimpan, maka muncul pesan diatas.Selanjutnya, cara melihat konfigurasi VLAN 1 switch. Caranya menggunakan perintah show interfaces vlan 1.
Switch#show interfaces vlan 1
Vlan1 is administratively down, line protocol is down
Hardware is CPU Interface, address is 000c.854a.b0b1 (bia 000c.854a.b0b1)
MTU 1500 bytes, BW 100000 Kbit, DLY 1000000 usec,
reliability 255/255, txload 1/255, rxload 1/255
Encapsulation ARPA, loopback not set
ARP type: ARPA, ARP Timeout 04:00:00
Last input 21:40:21, output never, 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 0 bits/sec, 0 packets/sec
5 minute output rate 0 bits/sec, 0 packets/sec
1682 packets input, 530955 bytes, 0 no buffer
Received 0 broadcasts (0 IP multicast)
0 runts, 0 giants, 0 throttles
0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored
563859 packets output, 0 bytes, 0 underruns
0 output errors, 23 interface resets
0 output buffer failures, 0 output buffers swapped out
Lihat ip address VLAN 1 dengan perintah show ip interfaces vlan 1.
Switch#show ip interface vlan 1
Vlan1 is administratively down, line protocol is down
Internet protocol processing disabled
Terlihat bahwa vlan 1 masih mati (down). Kemudian, kamu bisa melihat informasi IOS switch cisco kamu dengan perintah show version.
Switch#show version
