【正文】 ive VLAN號(hào) Step dynamic desirable—把端口設(shè)置為trunk如果對(duì)方端口是trunk, desirable, 或自動(dòng)模式 interface interfaceid進(jìn)入端口配置狀態(tài)Step舉例如下：Switch configure terminal Enter configuration mands, one per line. End with CNTL/Z.Switch(config) interface fastethernet0/1 Switch(configif) switchport mode access Switch(configif) switchport access vlan 2Switch(configif) end Switch配置VLAN Trunks命令 目的 Step7531 show vlan brief驗(yàn)證Step no vlan vlanid刪除某一VLAN. Step命令 目的 Step注意 show vlan {name vlanname | id vlanid}驗(yàn)證配置Step vlan vlanid mtu mtusize(可選) 修改MTU大小Step vlan database進(jìn)入VLAN配置狀態(tài)Step show vlan {name vlanname | id vlanid}驗(yàn)證Step mtu mtusize(可選) 改變MTU大小Step Step1 交換機(jī)必須配置成VTP透明模式當(dāng)需要生成VLAN 號(hào)從1006到4094. 本交換機(jī)支持基于每一VLAN的生成樹(PVST)，最多支持128個(gè)生成樹。由于VLAN被看成是一個(gè)邏輯網(wǎng)絡(luò)，其具有自己的網(wǎng)橋管理信息庫 (MIB) 并可支持自己的生成樹 VLAN作為邏輯定義的網(wǎng)絡(luò)示意圖VLAN常常與IP子網(wǎng)相聯(lián)系，同一IP子網(wǎng)屬于同一VLAN。531show interfaces [interfaceid] description顯示端口描述show runningconfig interface [interfaceid]顯示當(dāng)前配置中的端口配置情況show version顯示軟硬件等情況舉例如下:Switch show interfaces status Port Name Status Vlan Duplex Speed TypeGi0/1 connected routed afull a100 10/100/1000BaseTXGi0/2 wce server disabled routed auto auto 10/100/1000Base TXGi0/3 ip wccp webcache notconnect routed auto auto 10/100/1000Base TXGi0/4 notconnect routed auto auto 10/100/1000Base TXGi0/5 notconnect routed auto auto 10/100/1000Base TXGi0/6 disabled routed auto auto 10/100/1000Base TXGi0/7 disabled routed auto auto 10/100/1000Base TXGi0/8 disabled routed auto 100 10/100/1000Base TXGi0/9 notconnect routed auto auto 10/100/1000Base TXGi0/10 notconnect routed auto auto 10/100/1000Base TXGi0/11 disabled routed auto auto unknownGi0/12 notconnect routed auto auto unknown Switch show interfaces fastethernet 0/1 switchportName: Fa0/1Switchport: EnabledAdministrative Mode: static accessOperational Mode: downAdministrative Trunking Encapsulation: dot1qNegotiation of Trunking: OffAccess Mode VLAN: 1 (default)Trunking Native Mode VLAN: 1 (default)Trunking VLANs Enabled: ALLPruning VLANs Enabled: 21001 Protected: falseUnknown unicast blocked: disabledUnknown multicast blocked: disabled Voice VLAN: dot1p (Inactive)Appliance trust: 5Switch show runningconfig interface fastethernet0/2Building configuration...
