Catalyst 1924/2820软件升级
一、使用TFTP server安装软件
通过网络为交换机更新软件,在服务器和交换机之间必须经由IP连接.
1.必须具有一台TFTP server(如运行TFTP server软件的PC机)和一台治理工作站(如一台PC机),并且可以通过console口治理交换机:
使用终端仿真程序(如win95的HyperTerminal)和RJ-45-to-RJ-45的连接电缆和适配器:
RJ-45-to-DB-9 female DTE 适配器(标记"Terminal")
RJ-45-to-DB-25 female DTE 适配器(标记"Terminal")
RJ-45-to-DB-25 male DCE 适配器(标记"Modem")
2.以下是通过TFTP server更新软件的步骤:
1)将Cisco Catalyst 1900/2820 软件存于治理工作站.
2)将TFTP根目录设置为软件所在目录.
3)打开交换机,交换机正常启动.
4)在终端窗口显示治理菜单画面(以下为治理菜单).

Enter Selection:
5)如交换机未赋予IP地址,应该使用菜单赋予交换机IP addresss, subnet mask, 和default gateway.
6)确认交换机和TFTP server之间的连接正常. 例如:从服务器PING交换机.
7)进入Firmware配置菜单, 选择[S]选项,并键入TFTP server的IP地址.

8)选择[F]选项,键入TFTP server上的交换机软件的名称.
9)选择[T]选项执行 TFTP进行软件更新.
10)在菜单的系统信息区检查更新状态显示验证软件更新过程.
当软件更新完毕后,交换机大约有1分钟不响应命令,然后交换机重新启动并使用新的软件.
二、使用XMODEM协议安装软件
你可以通过通过XMODEM协议使用治理站为交换机更新软件.
软件安装的过程依靠你使用的modem软件.
1.你必须具有一台治理工作站(如一台PC机),并且可以通过console口治理交换机:
使用终端仿真程序(如win95的HyperTerminal)和RJ-45-to-RJ-45的连接电缆和适配器:
RJ-45-to-DB-9 female DTE 适配器(标记"Terminal")
RJ-45-to-DB-25 female DTE 适配器(标记"Terminal")
RJ-45-to-DB-25 male DCE 适配器(标记"Modem")
你可以使用win95的HyperTerminal(支持XMODEM协议).
2.以下是通过XMODEM协议更新软件的步骤:
1)打开交换机,交换机正常启动.
2)启动终端仿真程序,显示治理菜单.
3)从控制台显示RS-232 Interface 配置菜单,输入波特率(2400, 9600, 19200, 38400, 57600), data bits=8, stop bits=1, parity=none
使用57600波特率安装软件大约花10分钟时间.
4)从RS-232 Interface菜单,选择[G]选项激活组设置用于console口.
5)治理站要匹配console口的设置.
6)进入Firmware配置菜单,选择[U]选项使用XMODEM协议去安装软件.
7)在提示符下,选择Y启动软件安装过程.
8)在菜单的系统信息区检查更新状态显示验证软件更新过程.
当软件更新完毕后,交换机大约有1分钟不响应命令,然后交换机重新启动并使用新的软件.
交换机虚拟网(Virtual LANs)的设置:
Catalyst 5000上实现VLAN划分及外部VLAN路由设置
分配VTP域(a VTP Domain)
将Cat5000加入域
指定中继端口(a Trunk)
Dynamic ISL
分配VLAN到端口
设置VLAN 20
配置Router
-------------------------------------------------------------------
注:存在三个VLAN,在VLAN之间通过Router做路由.
-----------------------------------------------------------------
分配VTP域
什么是VTP?
VTP是VLAN Trunk Protocol的简写,它提供每个设备 (router 或 LAN-switch)在中继端口(trunk ports)发送广播. 这些广播被发送到一个组播地址,并被所有相邻设备接收. 这些广播列出了发送设备的治理域,它的配置修订号,已知的VLAN, 及已知VLAN的确定参数.通过听这些广播,在相同治理域的所有设备都可以学习到在发送设备上配置的新的VLAN.使用这种方法,新的 VLAN只需要在治理域内的一台设备上建立和配置.信息会自动被相同治理域内的其它设备学到.
分配VTP域
首先分配VTP域名(a VTP domain name),在相同治理域内的交换机可以通过VTP协议互相学习VTP信息.

--------------------------------------------------------------------------------
将Catalyst 5002加入域
需要将Catalyst 5002加入名为cisco的VTP治理域, 并设为VTP client,它将接收来自VTP server 的VTP配置及更新.
注重:Catalyst 5000系列交换机默认为VTP server.
cat5002> (enable)
cat5002> set vtp domain cisco mode client
指定中继端口(Trunk ports)
VLAN Trunk协议(VTP)只在中继口(ISL , LANE 和802.10)上传输,应在二个Catalyst5000
交换机间定义哪个口作为中继端口(Trunk port).
Inter-Switch Link (ISL) 中继用于Fast Ethernet和Gigabit Ethernet端口
IEEE 802.10中继用于FDDI/CDDI端口
LAN Emulation (LANE) 中继用于ATM 端口
Cat5001> (enable) set trunk 1/1 on
Port 1/1 mode set to on.
Cat5001> (enable)
Wed Jun 19 1996, 15:00:02 Port 1/1 has become trunk.
--------------------------------------------------------------------------------
Dynamic ISL
有了DISL(Dynamic ISL), 你不需要修改远端的Catalyst 5000;以下信息将显示在远端的Catalyst 5000.
Wed Jun 19 1996, 15:51:59 Port 1/2 has become trunk.

此时, VLAN 2 和VLAN 20 还未激活.所以在VLAN 2和VLAN 20的端口是inactive状态.
--------------------------------------------------------------------------------
设置VLAN 20
假如在网络里有VTP server和VTP clent,请在VTP server上设置VLAN 20
