簡介

本文提供在Cisco Catalyst 6500虛擬交換系統中替換壞管理器的逐步程式。

虛擬交換系統(VSS)包括兩個Catalyst 6500機箱。每個機箱都配備一個管理引擎。如果其中一個Supervisor因硬體故障而終止，則帶有預設配置的替換Supervisor不會自動成為VSS成員。這個新的Supervisor最初在獨立模式下啟動，它需要VSS配置才能在VSS模式下啟動。

必要條件

需求

嘗試此組態之前，請確保符合以下要求：

  • 將有效映像從活動VSS Supervisor複製到緊湊快閃記憶體裝置。

  • 將活動VSS配置複製到緊湊快閃記憶體裝置（可以相同）。

採用元件

本文中的資訊係根據以下軟體和硬體版本：

Cisco IOS®軟體版本12.2(33)SXH1或更新版本上的Cisco Catalyst 6500虛擬交換系統1440

本文中的資訊是根據特定實驗室環境內的裝置所建立。如果您的網路正在作用，請確保您已瞭解任何指令可能造成的影響。

設定

本節提供用於設定本文件中所述功能的資訊。

註：使用Command Lookup Tool(僅供已註冊客戶使用)可獲取本節中使用的命令的詳細資訊。

新的Supervisor要求您使用有效的映像和配置進行引導。映像可以與TFTP或精簡型快閃裝置一起複製。如果快閃記憶體不可用，也可以使用TFTP複製軟體映像和配置檔案。

  1. 將有效映像從活動VSS Supervisor複製到緊湊快閃記憶體裝置。

    VSS#dir sup-bootdisk:
Directory of sup-bootdisk:/
1 -rwx 117668516 Jan 22 2008 11:53:58 +00:00 s72033-
   ipservices_wan-vz.122-33.SXH1
2 -rwx 33554432 Aug 16 2007 12:40:22 +00:00 sea_log.dat
3 -rwx 7366 Aug 22 2007 20:05:42 +00:00 default-config

    請注意，在VSS模式下，主用和備用管理引擎運行相同版本的軟體映像。

    VSS#copy sup-bootdisk:s72033-ipservices_wan-vz.122-33.SXH1 disk0:
Destination filename [s72033-ipservices_wan-vz.122-33.SXH1]?
Copy in progress...CCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCC
   CCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCC

!--- Output suppressed.

  2. 將當前配置從活動VSS Supervisor複製到緊湊快閃記憶體裝置。

    VSS#copy running-config disk0:
Destination filename [startup-config]? 
        
        
11196 bytes copied in 0.712 secs (15725 bytes/sec)

安裝和配置新Supervisor

完成以下步驟以安裝和配置新Supervisor:

  1. 在機箱中安裝新的Supervisor，如果Supervisor上行鏈路用於VSL，則以物理方式連線它們。從快閃記憶體啟動映像。

  2. 清除新Supervisor的啟動配置檔案。要確保新Supervisor中不存在過時的配置，需要執行此步驟。

  3. 將先前複製到快閃記憶體裝置的軟體映像複製到新的supervisor sup-bootdisk:

    Router#copy disk0:s72033-ipservices_wan-vz.122-33.SXH1 sup-bootdisk:
Destination filename [s72033-ipservices_wan-vz.122-33.SXH1]?
Copy in progress ..CCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCC
CCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCC
117668516 bytes copied in 332.283 secs (354121 bytes/sec)

!--- Output suppressed.


!--- If you choose to download software image from a tftp server, connect one of the switch interfaces to the network in order to have connectivity to the tftp server. Configure IP address to the management interface; verify the connectivity between the switch and the tftp server.


!--- The management IP address should be different from what is already assigned to active VSS switch. !--- Configure management IP address 
Router(config)#interface gig 1/3
Router(config-if)#ip address 10.10.10.100 255.255.255.0
Router(config-if)#no shutdown

!--- verify Management interface status and configuration

Router#show interface gig 1/3
GigabitEthernet1/3 is up, line protocol is up (connected)
Hardware is C6k 1000Mb 802.3, address is 0005.dce7.8180 
   (bia 0005.dce7.8180)
Internet address is 10.10.10.100/24

!--- Output omitted !--- If the TFTP server and switch management interface are not in the same layer-3 subnet, add a (default) route.

Router(config)#ip route 0.0.0.0 0.0.0.0 10.10.10.1

!--- verify IP connectivity between switch and TFTP server

Router#ping 10.20.20.200

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.20.20.200, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/1/4 ms

!---Copy the new software image into supervisor bootflash:

Router#copy tftp: sup-bootdisk:
Address or name of remote host []? 10.20.20.200
Source filename []? s72033-ipservices_wan-vz.122-33.SXH1
Destination filename [s72033-ipservices_wan-vz.122-33.SXH1]?
Copy in progress ..CCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCC
CCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCC

!--- Output omitted

  4. 將先前儲存在快閃記憶體裝置上的活動Supervisor配置複製到新的Supervisor啟動配置檔案中。

    Router#copy disk0:VSS.cfg startup-config
Destination filename [startup-config]?
11196 bytes copied in 7.460 secs (1501 bytes/sec)
Router#

    註：此步驟至關重要，因為新增了引導正確的IOS軟體映像所需的VSS配置和任何引導變數。

    
!--- Highlighted VSS configuration commands are critical to boot up the supervisor in VSS mode. !--- Verify VSS configuration in the startup-config file

Router#more nvram:startup-config
!
hostname VSS
boot system flash sup-bootdisk:s72033-ipservices_wan-vz.122-33.SXH1

!--- Switch Virtual domain 
         
           is configured with respective switch priorities 
         

switch virtual domain 1
switch mode virtual 

!--- this command gets populated upon converting standalone switch to VSS mode. Make sure this command is part the configuration.

switch 1 priority 110
switch 2 priority 100


!--- Verify Virtual Switch Link (VSL) configuration

interface Port-channel1
no switchport
no ip address
switch virtual link 1
mls qos trust cos
no mls qos channel-consistency
!
interface Port-channel2
no switchport
no ip address
switch virtual link 2
mls qos trust cos
no mls qos channel-consistency

!--- Physical interfaces that are part of VSL

interface TenGigabitEthernet1/1/4
no switchport
no ip address
mls qos trust cos 
channel-group 1 mode on

interface TenGigabitEthernet1/1/5
no switchport
no ip address
mls qos trust cos 
channel-group 1 mode on

interface TenGigabitEthernet2/1/4
no switchport
no ip address
mls qos trust cos 
channel-group 2 mode on

interface TenGigabitEthernet2/1/5
no switchport
no ip address
mls qos trust cos 
channel-group 2 mode on

  5. 配置用於識別虛擬交換域中Catalyst 6500交換機的VSS Switch_ID。因為VSS只能包含兩台交換機，所以您需要根據活動交換機上定義的值選擇1或2。不能使用1或2以外的任何值。

    
!--- Verify active Switch_ID on the active switch

Router#switch read switch_num local
Read switch_num from Active rommon is 1

!--- Note that since Switch_ID=1 is used for active switch, we would define Switch_ID=2 in the new supervisor.


!--- Configure the Switch_ID on the supervisor.


!--- Below command sets a Switch_ID ROMMON variable. It is used during VSS boot up to identify a switch within a VSS domain. !--- Note that the Switch_ID doesn’t dictate the state (active vs. standby) of the supervisor.

Router#switch set switch_num 2 local
Set rommon's switch_num to 2

!--- Verify the Switch_ID configuration on the new supervisor.

Router#switch read switch_num local
Read switch_num from Active rommon is 2

  6. 重新載入交換機，以便重新載入時，交換機以VSS模式啟動。

    caution 注意：此時不要將運行配置儲存到啟動配置。如果這樣做，啟動配置將被預設配置覆蓋，並且交換機不會在VSS模式下啟動。

    注意：要在多個子網上配置VSS，不需要在VSS上進行備用配置。網關路由器應設定為VLAN SVI。

驗證

目前沒有適用於此組態的驗證程序。

輸出直譯器工具(僅供已註冊客戶使用)(OIT)支援某些show命令。使用OIT檢視show命令輸出的分析。

疑難排解

本節提供的資訊可用於對組態進行疑難排解。

Supervisor引擎之間的軟體不匹配

如果Supervisor引擎之間存在軟體不匹配，則獨立Supervisor在RPR冗餘模式（不處於SSO冗餘模式）下啟動，並且VSS沒有完全初始化。

為了解決此問題，請確保備用Supervisor的快閃記憶體中存在所需的軟體，且引導語句指向正確的軟體。重新載入獨立Supervisor，使其使用正確的軟體啟動並加入VSS。
