不同vlan計(jì)算機(jī)不能互相訪問?
一般情況下三層交換機(jī)上的vlan默認(rèn)是關(guān)閉vlan互通的,有的是默認(rèn)是開通vlan互通的。具體設(shè)置看交換機(jī)品牌型號(hào),每家交換機(jī)的命令設(shè)置稍微不同,我們以TPSG5428三層交換機(jī)來舉例吧,這個(gè)默認(rèn)是互通各vlan的。命令設(shè)置參數(shù)大體都差不多,可結(jié)合本命令步驟參考,來對(duì)應(yīng)自己具體型號(hào)說明書做調(diào)整命令參數(shù)來配置vlan互通隔離。
假設(shè)有一個(gè)這樣環(huán)境的網(wǎng)絡(luò)拓?fù)?/p>
要求兩個(gè)部門vlan不能互相訪問
部門信息如下
A部門用 vlan 24 192.168.24.X/24 , B部門用 vlan30 192.168.30.x/24
該如何通過TPSG5428三層交換機(jī)來實(shí)現(xiàn)設(shè)置呢?
步驟如下:
進(jìn)入交換機(jī)命令界面
Xshell 6 (Build 0125)

TL-SG5428>
輸入en (進(jìn)入特權(quán)模式)
TL-SG5428>en
TL-SG5428#
在輸入config (進(jìn)入全局模式)
TL-SG5428#config
TL-SG5428(config)#
再輸入access-list create 505 (創(chuàng)建一個(gè)ID號(hào)為505的標(biāo)準(zhǔn)IP ACL )
TL-SG5428(config)#access-list create 505
再輸入access-list create 506 (創(chuàng)建一個(gè)ID號(hào)為506的標(biāo)準(zhǔn)IP ACL )
TL-SG5428(config)#access-list create 506
再輸入
access-list standard 505 rule 5 deny sip 192.168.24.0 smask dip 192.168.30.0 dmask 255.255.255.0 (創(chuàng)建一個(gè)ID號(hào)為505的標(biāo)準(zhǔn)IP ACL,為其添加規(guī)則rule id 5,其中源IP地址為192.168.24.0,掩碼為255.255.255.0,目的地址192.168.30.0 掩碼255.255.255.0 )
TL-SG5428(config)#access-list standard 505 rule 5 deny sip 192.168.24.0 smask dip 192.168.30.0 dmask 255.255.255.0
再輸入
access-list standard 506 rule 6 deny sip 192.168.30.0 smask dip 192.168.24.0 dmask 255.255.255.0(創(chuàng)建一個(gè)ID號(hào)為506的標(biāo)準(zhǔn)IP ACL,為其添加規(guī)則rule id 6,其中源IP地址為192.168.30.0,掩碼為255.255.255.0,目的地址192.168.24.0 掩碼255.255.255.0 )
TL-SG5428(config)#access-list standard 506 rule 6 deny sip 192.168.30.0 smask dip 192.168.24.0 dmask 255.255.255.0
再輸入access-list policy name A (添加一個(gè)名為A的Policy )
TL-SG5428(config)#access-list policy name A
再輸入access-list policy name B (添加一個(gè)名為B的Policy )
TL-SG5428(config)#access-list policy name B
再輸入access-list policy action A 505 (將A的 Policy綁定到505 ACL ID )
TL-SG5428(config)#access-list policy action A 505
再輸入access-list policy action B 506 (將B的 Policy綁定到506 ACL ID)
TL-SG5428(config)#access-list policy action B 506
再輸入interface vlan 24 (進(jìn)入接口配置模式)
TL-SG5428(config)#interface vlan 24
再輸入access-list bing A (將A的Policy綁定到VLAN 24)
TL-SG5428(config-if)#access-list bing A
再輸入exit
TL-SG5428(config-if)#exit
再輸入interface vlan 30 (進(jìn)入接口配置模式)
TL-SG5428(config)#interface vlan 30
再輸入access-list bing B (將B的Policy綁定到VLAN 30)
TL-SG5428(config-if)#access-list bing B
輸入exit
TL-SG5428(config-if)#exit
這樣就完成vlan隔離配置了。
