Part 1: Configure Basic Switch Sett

Part 1: Configure Basic Switch Settings
Step 1: Configure basic switch parameters.
a. Assign each switch a hostname according to the topology diagram.
b. Configure all required ports as trunks, depending on the connections between devices.
Note: If the ports are configured with dynamic auto mode, and you do not set the mode of the ports to trunk, the links do not form trunks and remain access ports. The default mode on a 2960 switch is dynamic auto.
Part 2: Configure an EtherChannel with Cisco PAgP
Note: When configuring EtherChannels, it is recommended to shut down the physical ports being grouped on both devices before configuring them into channel groups. Otherwise, the EtherChannel Misconfig Guard may place these ports into err-disabled state. The ports and port channels can be re-enabled after EtherChannel is configured.
Step 1: Configure Port Channel 1.
a. The first EtherChannel created for this activity aggregates ports F0/22 and F0/21 between S1 and S3. Use the show interfaces trunk command to ensure that you have an active trunk link for those two links.
b. On both switches, add ports F0/21 and F0/22 to Port Channel 1 with the channel-group 1 mode desirable command. The mode desirable option enables the switch to actively negotiate to form a PAgP link.
c. Configure the logical interface to become a trunk by first entering the interface port-channel number command and then the switchport mode trunk command. Add this configuration to both switches.
Step 2: Verify Port Channel 1 status.
a. Issue the show etherchannel summary command to verify that EtherChannel is working on both switches. This command displays the type of EtherChannel, the ports utilized, and port states.
b. If the EtherChannel does not come up, shut down the physical interfaces on both ends of the EtherChannel and then bring them back up again. This involves using the shutdown command on those interfaces, followed by a no shutdown command a few seconds later.
The show interfaces trunk and show spanning-tree commands also show the port channel as one logical link.
Part 3: Configure an 802.3ad LACP EtherChannel
Step 1: Configure Port Channel 2.
a. In 2000, the IEEE released 802.3ad, which is an open standard version of EtherChannel. Using the previous commands, configure the link between S1 and S2 on ports G0/1 and G0/2 as an LACP EtherChannel. You must use a different port channel number on S1 than 1, because you already used that in the previous step. To configure a port channel as LACP, use the interface configuration mode channel-group number mode active command. Active mode indicates that the switch actively tries to negotiate that link as LACP, as opposed to PAgP.
Step 2: Verify Port Channel 2 status.
a. Use the show commands from Part 1 Step 2 to verify the status of Port Channel 2. Look for the protocol used by each port.
Part 4: Configure a Redundant EtherChannel Link
Step 1: Configure Port Channel 3.
There are various ways to enter the channel-group number mode command:
S2(config)# interface range f0/23 - 24
S2(config-if-range)# channel-group 3 mode ?
active Enable LACP unconditionally
auto Enable PAgP only if a PAgP device is detected
desirable Enable PAgP unconditionally
on Enable Etherchannel only
passive Enable LACP only if a LACP device is detected
a. On switch S2, add ports F0/23 and F0/24 to Port Channel 3 with the channel-group 3 mode passive command. The passive option indicates that you want the switch to use LACP only if another LACP device is detected. Statically configure Port Channel 3 as a trunk interface.
b. On switch S3, add ports F0/23 and F0/24 to Port Channel 3 with the channel-group 3 mode active command. The active option indicates that you want the switch to use LACP unconditionally. Statically configure Port Channel 3 as a trunk interface.
Step 2: Verify Port Channel 3 status.
a. Use the show commands from Part 1 Step 2 to verify the status of Port Channel 3. Look for the protocol used by each port.
b. Port Channel 2 is not operative because spanning tree protocol placed some ports into blocking mode. Unfortunately, those ports were Gigabit ports. To restore these ports, configure S1 to be primary root for VLAN 1 or set the priority to 24576.

第 1 部分︰ 配置基本开关设置第 1 步︰ 配置基本开关参数。a.分配每个交换机根据拓扑图的主机名。b.将所有所需的端口配置为树干,具体取决于设备之间的连接。注意︰ 如果端口配置动态自动模式,并且您不设置端口模式到主干,链接不形成树干和保持访问端口。2960 交换机上的默认模式是动态的汽车。第 2 部分︰ 使用思科 PAgP 配置干道注意︰ 在配置时 EtherChannels,它被建议关闭之前将其配置为通道组被分组在两个设备上的物理端口。否则,干道 Misconfig 警卫队可能会将这些端口放入犯错禁用状态。干道配置后可以重新启用的端口和端口通道。第 1 步︰ 配置端口通道 1。a.第一次干道为此活动聚合端口 F0/22 和 F0/21 S1 和 S3 之间创建。使用显示接口树干命令以确保你有积极的树干链接这些两个链接。b.在两个交换机,添加端口 F0/21 和 F0/22 端口通道 1 通道组 1 模式可取命令。模式可取使开关积极洽谈,形成 PAgP 链接。c.配置逻辑接口,由第一次进入界面端口通道编号命令然后交换机端口模式树干命令成为一根树干。将此配置添加到这两个开关。第 2 步︰ 验证端口通道 1 的状态。a.发出显示干道摘要命令来验证干道工作在两个交换机。此命令显示的干道类型、 端口的利用,和港口国。b.如果干道不出来,关闭两端的干道上的物理接口,然后把它们拿回去。这涉及在这些接口,其次是没有关机命令几秒钟后上使用 shutdown 命令。显示接口的树干和显示生成树命令也显示端口通道作为一个逻辑链路。第 3 部分︰ 配置 802.3 a d LACP 干道第 1 步︰ 配置端口通道 2。a.在 2000 年,IEEE 发表 802.3 a d,是一个开放的标准版本的干道。使用以前的命令,在 G0/1 和 G0/2 端口上配置 S1 和 S2 之间的联系作为 LACP 干道。你必须使用一个不同的端口通道号上 S1 比 1,因为您已经使用,在上一步。要将一个端口通道配置为 LACP,使用接口配置模式通道组号码模式积极命令。主动模式指示开关积极尝试作为 LACP,而不是 PAgP 谈判这种联系。第 2 步︰ 验证端口通道 2 状态。a.使用部分 1 的步骤 2 中显示命令来验证端口通道 2 的地位。寻找每个端口使用的协议。第 4 部分︰ 配置冗余的干道链路第 1 步︰ 配置端口通道 3。有各种方法来输入通道组数模式命令︰S2(config) # 接口范围 f0/23-24S2(config-if-range) # 3 组通道模式吗?积极启用 LACP 无条件只有当检测到 PAgP 设备自动启用 PAgP理想使 PAgP 无条件在启用干道上被动的启用 LACP 仅当检测到 LACP 设备a.在开关 S2,将端口 F0/23 和 F0/24 添加到端口通道 3,与第 3 组通道模式被动命令。被动的选项表示您希望转而使用 LACP 仅当检测到另一个 LACP 设备。将配置为静态端口通道 3 作为主干接口。b.在开关 S3,将端口 F0/23 和 F0/24 添加到端口通道 3,与第 3 组通道模式活动的命令。活动选项表示您希望转而使用 LACP 无条件。将配置为静态端口通道 3 作为主干接口。第 2 步︰ 验证端口通道 3 状态。a.使用部分 1 的步骤 2 中显示命令来验证端口通道 3 的状态。寻找每个端口使用的协议。b.端口通道 2 不是手术的因为生成树协议置于阻止模式下的一些港口。不幸的是,这些端口是千兆位端口。若要还原这些端口,配置 S1 为 VLAN 1 的主根或到 24576 设置的优先级。

第1部分:配置基本开关设置步骤1:配置基本开关参数。A.分配每个开关根据拓扑图的主机名。根据设备之间的连接,将所有必需的端口配置为中继线。注意:如果端口配置了动态自动模式,并且没有将端口模式设置为中继线,则链接不会形成中继线并保持访问端口.。2960开关上的默认模式是动态自动。2部分:与思科PAgP配置以太通道注:当配置以太网信道,建议关闭物理端口分组对设备配置前到通道组。否则,以太通道misconfig警卫将这些端口为错误禁用状态。港口和港口通道可以重新在以太通道配置启用。步骤1:配置端口通道1。A.第一道此活动聚集的港口/ 22 / 21,F0 F0 S1和S3之间产生。使用“显示接口”中继命令,以确保您有这两个链接的活动中继链接.。B.交换机上,添加端口21和F0 F0 / / 22端口通道1通道1组模式可取的命令。模式的理想选择,使开关积极协商形成使用链接。配置逻辑接口成为中继首先进入接口通道数命令然后switchport mode trunk命令。将此配置添加到两个开关。步骤2:验证端口通道1状态。A.问题的显示以总结命令确认EtherChannel正在研究这两个开关。此命令显示以太通道的类型、端口的利用,以及港口国。如果以不上来,关闭物理接口的以太通道两端,然后把他们带回来了。这包括使用这些接口上的“关机”命令,随后几秒钟后将没有关机命令.。显示接口中继线和显示生成树命令也将端口通道显示为一个逻辑链路.。3部分:配置802.3ad LACP EtherChannel步骤1:配置端口通道2。答:2000、发布的IEEE 802.3ad标准版是一个开放的通道。使用前面的命令,配置端口G0/1和G0 / 2 S1和S2之间的联系作为LACP以太通道。你必须使用不同的端口号S1到1,因为你已经习惯了,在以前的步骤。配置端口通道配置,使用接口配置模式通道组数模式激活命令。主动模式表明开关积极洽谈联系,LACP,反对PAgP。步骤2:验证端口通道2状态。A.使用第1部分步骤2中的显示命令来验证端口通道2的状态。查找每个端口使用的协议。4部分:配置冗余以太通道链路步骤1:配置端口通道3。有多种方式进入通道组编号模式命令:S2(config)#接口范围f0 / 23 - 24S2(如果范围)#通道组3模式?无条件积极启用LACP汽车使PAGP只有使用设备检测理想使PAgP无条件只有在使以太通道被动启用LACP只有LACP设备检测A.开关S2,添加端口23和F0 F0 / / 24端口通道3通道3组被动命令模式。被动的选择表明你想切换到另一个或只有设备检测使用LACP。静态配置端口通道3作为中继接口。B.开关S3,添加端口23和F0 F0 / / 24端口通道3通道3组模式的主动命令。积极的选择表明你想要切换到使用LACP协议无条件。静态配置端口通道3作为中继接口。步骤2:验证端口通道3状态。A.使用第1部分步骤2中的显示命令来验证端口通道3的状态。查找每个端口使用的协议。由于生成树协议将一些端口放入阻塞模式,端口通道2无法运行。不幸的是,这些端口是千兆端口。要恢复这些端口,配置S1是VLAN 1或设置优先级24576初生根。
