1. Uređaji

Uređaj	Model	Hostname
Router	2911	ISP1 (NTP master)
Router	2911	ISP2
Router	2911	R1 (GW1)
Router	2911	R2 (GW2)
Switch	2960-24TT	SW1 (VTP server)
Switch	2960-24TT	SW2
Switch	2960-24TT	SW3
PC	PC-PT	PC1, PC2, PC3, PC4
IP Phone	7960	IPPhone1, IPPhone2
AP	AP-PT	AP1 (VLAN 11), AP2 (VLAN 31)
Laptop	Laptop-PT	Laptop1, Laptop2 (WiFi)

2. Kabliranje

Internet backbone

ISP1 Gi0/0 ── ISP2 Gi0/0 1.1.3.0/30
R1 Gi0/0 ── ISP1 Gi0/1 1.1.1.0/30
R2 Gi0/0 ── ISP2 Gi0/1 1.1.2.0/30

LAN-A backbone (SW1 jezgra)

R1 Gi0/1 ── SW1 Gi0/1 (trunk)
R2 Gi0/1 ── SW1 Gi0/2 (trunk)
SW1 Fa0/23-24 ── SW2 Fa0/23-24 Po1 LACP
SW1 Fa0/21-22 ── SW3 Fa0/23-24 Po2 PAgP

Edge (access)

SW2 Fa0/1 → PC1 VLAN 11 sticky/shutdown
SW2 Fa0/2 → PC2 VLAN 11 static/restrict
SW2 Fa0/3 → IPPhone1 (voice 21, data 11)
SW2 Fa0/4 → AP1 (VLAN 11)
SW3 Fa0/1 → PC3 VLAN 31 dynamic/protect
SW3 Fa0/2 → IPPhone2 (voice 21, data 31)
SW3 Fa0/3 → AP2 (VLAN 31)
SW3 Fa0/4 → PC4 (VLAN 31)

3. IP plan

Segment	Subnet	Napomene
ISP1 ↔ ISP2	1.1.3.0/30	.1 / .2
R1 ↔ ISP1	1.1.1.0/30	.1 / .2
R2 ↔ ISP2	1.1.2.0/30	.1 / .2
VLAN 11 DATA	10.1.11.0/24	HSRP VIP .1, R1 .2, R2 .3
VLAN 21 VOICE	10.1.21.0/24	HSRP VIP .1, R1 .2, R2 .3
VLAN 31 WIFI	10.1.31.0/24	HSRP VIP .1, R1 .2, R2 .3

HSRP active: R1 = VLAN 11 + 31 · R2 = VLAN 21. DHCP range .101-.254.

4. Configi (copy-paste u CLI tab)

Otvorite svaki uređaj u PT → CLI tab → pritisnite Enter → paste-ajte. Nakon kraja: copy running-config startup-config (već je u configu kao write memory).

5. GUI koraci (što se ne radi CLI-jem)

PC-ovi

Svaki PC → Desktop → IP Configuration → DHCP (dobit će .101+)

IP Phones

Phone → Physical → dodaj Power Adapter. Phone → Config → DHCP. Brojevi se registriraju iz auto assign (1001, 1002).

AP1 + AP2

Config → Port 1 → SSID LAN-A-WIFI, Auth WPA2-PSK, PSK KRMIS2026!, Encryption AES.

Laptopi

Ugasiti → Physical → makni NIC, stavi WPC300N wireless karticu → upali. Desktop → PC Wireless → Connect → LAN-A-WIFI → PSK KRMIS2026!. Desktop → IP Config → DHCP.
