交換機虛擬網(wǎng)(Virtual LANs)的設(shè)置:

Catalyst 5000上實現(xiàn)VLAN劃分及外部VLAN路由設(shè)置

分配VTP域(a VTP Domain)

將Cat5000加入域

指定中繼端口(a Trunk)

Dynamic ISL

分配VLAN到端口

設(shè)置VLAN 20

配置Router

注:存在三個VLAN,在VLAN之間通過Router做路由.

分配VTP域

什么是VTP?

VTP是VLAN Trunk PRotocol的簡寫,它提供每個設(shè)備 (router 或 LAN-switch)在中繼端口(trunk ports)發(fā)送廣播. 這些廣播被發(fā)送到一個組播地址,并被所有相鄰設(shè)備接收. 這些廣播列出了發(fā)送設(shè)備的治理域,它的配置修訂號,已知的VLAN, 及已知VLAN的確定參數(shù).通過聽這些廣播,在相同治理域的所有設(shè)備都可以學習到在發(fā)送設(shè)備上配置的新的VLAN.使用這種方法,新的 VLAN只需要在治理域內(nèi)的一臺設(shè)備上建立和配置.信息會自動被相同治理域內(nèi)的其它設(shè)備學到.

分配VTP域

首先分配VTP域名(a VTP domain name),在相同治理域內(nèi)的交換機可以通過VTP協(xié)議互相學習VTP信息.

將Catalyst 5002加入域

需要將Catalyst 5002加入名為cisco的VTP治理域, 并設(shè)為VTP client,它將接收來自VTP server 的VTP配置及更新.

注重:Catalyst 5000系列交換機默認為VTP server.

cat5002> (enable)

cat5002> set vtp domain cisco mode client

指定中繼端口(Trunk ports)

VLAN Trunk協(xié)議(VTP)只在中繼口(ISL , LANE 和802.10)上傳輸,應在二個Catalyst5000

交換機間定義哪個口作為中繼端口(Trunk port).

Inter-Switch Link (ISL) 中繼用于Fast Ethernet和Gigabit Ethernet端口

IEEE 802.10中繼用于FDDI/CDDI端口

LAN Emulation (LANE) 中繼用于ATM 端口

Cat5001> (enable) set trunk 1/1 on

Port 1/1 mode set to on.

Cat5001> (enable)

Wed Jun 19 1996, 15:00:02 Port 1/1 has become trunk.

--------------------------------------------------------------------------------

Dynamic ISL

有了DISL(Dynamic ISL), 你不需要修改遠端的Catalyst 5000;以下信息將顯示在遠端的Catalyst 5000.

Wed Jun 19 1996, 15:51:59 Port 1/2 has become trunk.

Cat5001> (enable) sho trunk

注重: DISL在Cisco IOS軟件中不支持.

分配VLAN到端口

Cat5001> (enable) set vlan 2 3/2-20

VLAN 2 modified.

VLAN 1 modified.

VLAN Mod/Ports

---- -----------------------

3/2-20

Cat5001> (enable) set vlan 20 5/1-6

VLAN 20 modified.

VLAN 1 modified.

VLAN Mod/Ports

---- -----------------------

20 1/1

5/1-6

Configure additional information for VLAN 20.

On the other Catalyst 5000 :

Cat5002> (enable) set vlan 2 4/1-2,5/6-12

VLAN 2 modified.

VLAN 1 modified.

VLAN Mod/Ports

---- -----------------------

2 1/2

4/1-3,4/5-23

5/6-12

Configure additional information for VLAN 20.

Cat5002> (enable) set vlan 20 5/1-5

VLAN 20 modified.

VLAN 1 modified.

VLAN Mod/Ports

---- -----------------------

20 1/2

5/1-5

Configure VLAN 20 on a VTP server.

顯示端口配置

Cat5001> (enable) show port

Port Name Status Vlan Level Duplex Speed Type

1/1 connected 1 normal half 100 100BaseTX

1/2 connected trunk normal half 100 100BaseTX

2/1 connecting 1 normal half 100 FDDI

2/2 connected 1 normal half 100 FDDI

4/1 inactive 2 normal half 10 10BaseT

4/2 inactive 2 normal half 10 10BaseT

4/3 inactive 2 normal half 10 10BaseT

4/4 notconnect 1 normal half 10 10BaseT

4/5 inactive 2 normal half 10 10BaseT

4/6

此時, VLAN 2 和VLAN 20 還未激活.所以在VLAN 2和VLAN 20的端口是inactive狀態(tài).

設(shè)置VLAN 20

假如在網(wǎng)絡(luò)里有VTP server和VTP clent,請在VTP server上設(shè)置VLAN 20

Cat5001> (enable) set vlan 20

VLAN 20 modified

這將激活在所有治理域cisco內(nèi)的VLAN 20

Cat5001> (enable) sho vlan 20
