設(shè)計(jì)做兼職最好的網(wǎng)站如何優(yōu)化搜索引擎
組網(wǎng)需求
說(shuō)明
S5720I-10X-PWH-SI-AC 和 S5720I-6X-PWH-SI-AC 不支持此配置。
如 圖 3-23 所示，為了增加設(shè)備的容量采用設(shè)備堆疊技術(shù)，將 Switch3 和 Switch4通過(guò)專用的堆疊電纜鏈接起來(lái)，對(duì)外呈現(xiàn)為一臺(tái)邏輯交換機(jī)。為了實(shí)現(xiàn)設(shè)備間的備份、提高可靠性，采用跨堆疊設(shè)備Eth-Trunk接口技術(shù)，將不同設(shè)備上的物理接口加入同一個(gè)Eth-Trunk接口。在網(wǎng)絡(luò)無(wú)任何故障情況下，在PE設(shè)備上查看成員口信息時(shí)，發(fā)現(xiàn)VLAN2的數(shù)據(jù)流量會(huì)通過(guò)成員口GE1/0/1和GE1/0/2轉(zhuǎn)發(fā)，VLAN3的數(shù)據(jù)流量通過(guò)成員口GE1/0/1和GE1/0/2轉(zhuǎn)發(fā)。增加了堆疊設(shè)備之間的帶寬承載能力，也降低了流量轉(zhuǎn)發(fā)效率。為了有效保證VLAN2的數(shù)據(jù)流量通過(guò)成員口GE1/0/1轉(zhuǎn)發(fā)，VLAN3的數(shù)據(jù)流量通過(guò)成員口GE1/0/2轉(zhuǎn)發(fā)，可在堆疊設(shè)備上使能Eth-Trunk接口流量本地優(yōu)先轉(zhuǎn)發(fā)功能。
配置思路
采用如下的思路配置 Eth-Trunk 接口流量本地優(yōu)先轉(zhuǎn)發(fā)功能：
1. 創(chuàng)建 Eth-Trunk 接口。
2. 加入 Eth-Trunk 的成員接口。
3. 使能 Eth-Trunk 接口流量本地優(yōu)先轉(zhuǎn)發(fā)功能。
4. 配置各接口加入相應(yīng) VLAN ，實(shí)現(xiàn)二層互通。
操作步驟
步驟 1 創(chuàng)建 Eth-Trunk 接口，并配置允許通過(guò)的 VLAN
# 配置 Stack 。

[PE-Eth-Trunk10] port trunk allow-pass vlan all
[PE-Eth-Trunk10] undo port trunk allow-pass vlan 1
[PE-Eth-Trunk10] quit
步驟 2 加入 Eth-Trunk 的成員接口
# 配置 Stack 。
[Stack] interface gigabitethernet 1/0/4
[Stack-GigabitEthernet1/0/4] eth-trunk 10
[Stack-GigabitEthernet1/0/4] quit
[Stack] interface gigabitethernet 2/0/4
[Stack-GigabitEthernet2/0/4] eth-trunk 10
[Stack-GigabitEthernet2/0/4] quit
# 配置 PE 。
[PE] interface gigabitethernet 1/0/1
[PE-GigabitEthernet1/0/1] eth-trunk 10
[PE-GigabitEthernet1/0/1] quit
[PE] interface gigabitethernet 1/0/2
[PE-GigabitEthernet1/0/2] eth-trunk 10
[PE-GigabitEthernet1/0/2] quit
步驟 3 在堆疊設(shè)備上使能 Eth-Trunk 接口流量本地優(yōu)先轉(zhuǎn)發(fā)功能
對(duì)于 S2730S-S 、 S5735-L-I 、 S5735-L1 、 S300 、 S5735-L 、 CloudEngine S5735S-L1 、
S5735S-L 、 S5735-S 、 S5735S-S 、 S5735S-L-M 、 S500 ：
[Stack] local-preference enable
對(duì)于除 S2730S-S 、 S5735-L-I 、 S5735-L1 、 S300 、 S5735-L 、 CloudEngine S5735S
L1 、 S5735S-L 、 S5735-S 、 S5735S-S 、 S5735S-L-M 、 S500 之外的設(shè)備：
[Stack] interface eth-trunk 10
[Stack-Eth-Trunk10] local-preference enable
[Stack-Eth-Trunk10] quit
步驟 4 配置二層轉(zhuǎn)發(fā)功能
# 配置 Stack 。
[Stack] vlan batch 2 3
[Stack] interface gigabitethernet 1/0/3
[Stack-GigabitEthernet1/0/3] port link-type trunk
[Stack-GigabitEthernet1/0/3] port trunk allow-pass vlan 2
[Stack-GigabitEthernet1/0/3] undo port trunk allow-pass vlan 1
[Stack-GigabitEthernet1/0/3] quit
[Stack] interface gigabitethernet 2/0/3
[Stack-GigabitEthernet2/0/3] port link-type trunk
[Stack-GigabitEthernet2/0/3] port trunk allow-pass vlan 3
[Stack-GigabitEthernet2/0/3] undo port trunk allow-pass vlan 1
[Stack-GigabitEthernet2/0/3] quit
# 配置 Switch1 。
<HUAWEI> system-view
[HUAWEI] sysname Switch1
[Switch1] vlan 2
[Switch1-vlan2] quit
[Switch1] interface gigabitethernet 0/0/1
[Switch1-GigabitEthernet0/0/1] port link-type trunk
[Switch1-GigabitEthernet0/0/1] port trunk allow-pass vlan 2
[Switch1-GigabitEthernet0/0/1] undo port trunk allow-pass vlan 1
[Switch1-GigabitEthernet0/0/1] quit
[Switch1] interface gigabitethernet 0/0/2
[Switch1-GigabitEthernet0/0/2] port link-type trunk

[Switch1-GigabitEthernet0/0/2] undo port trunk allow-pass vlan 1
[Switch1-GigabitEthernet0/0/2] quit
# 配置 Switch2 。

[HUAWEI] sysname Switch2
[Switch2] vlan 3
[Switch2-vlan3] quit
[Switch2] interface gigabitethernet 0/0/1
[Switch2-GigabitEthernet0/0/1] port link-type trunk
[Switch2-GigabitEthernet0/0/1] port trunk allow-pass vlan 3
[Switch2-GigabitEthernet0/0/1] undo port trunk allow-pass vlan 1
[Switch2-GigabitEthernet0/0/1] quit
[Switch2] interface gigabitethernet 0/0/2
[Switch2-GigabitEthernet0/0/2] port link-type trunk
[Switch2-GigabitEthernet0/0/2] port trunk allow-pass vlan 3
[Switch2-GigabitEthernet0/0/2] undo port trunk allow-pass vlan 1
[Switch2-GigabitEthernet0/0/2] quit
步驟 5 檢查配置結(jié)果
上述配置成功后，在任意視圖下執(zhí)行命令 display trunkmembership eth-trunk ，可
以看到 Eth-Trunk 接口的成員口信息。例如：
以 Stack 的顯示為例。
<Stack> display trunkmembership eth-trunk 10
Trunk ID: 10
Used status: VALID
TYPE: ethernet
Working Mode : Normal
Number Of Ports in Trunk = 2
Number Of Up Ports in Trunk = 2
Operate status: up
Interface GigabitEthernet1/0/4, valid, operate up, weight=1
Interface GigabitEthernet2/0/4, valid, operate up, weight=1
