交换技术之七-Configuring the Catalyst 5000 Series Switch-剑心通明-ChinaUnix博客

对Catalyst 5000系列的交换机进行配置可以有2种方式,可以通过购买一个叫做CWSI(Cisco Works fortched Internetworks)的产品或者通过CLI进行配置.CLI可以通过交换机的console port用类似HyperTerminal的终端程序进行访问,把线缆的一端连接到PC的com口,另一端连接到交换机的console port即可

Catalyst 5000系列使用的操作系统并不是IOS,而是CatOS(Catalyst Operating System).当交换机电源启动以后,会运行正常的bootstrap程序并且进行POST测试.下面的输出摘自使用supervisor engine II的Catalyst 5000:

如果是交换机的第一次启动,或者假如交换机的配置文件被擦除了,交换机将发出BOOTP请求,RARP将解析它的IP地址,如下:
Sending RARP request with address 00:40:02:24:25:ff
Sending bootp request with address: 00:40:02:24:25:ff
Sending RARP request with address 00:40:02:24:25:ff

Catalyst 5000系列的CLI有点类似Cisco路由器的CLI.同样,CatOS也有在线帮助,使用问号或者help命令查看当前可用命令和介绍,语法等信息,如下:
console> (enable) ?

-More-
-More-表示还有更多的输出,可以按回车键一次显示一行,也可以按其他键1次显示1页,或者按下q键退出查看输出
当你输出一个不正确的命令的时候,将收到提示信息,如下:
Cat5000> (enable) hlp
Unknown command "hlp". Use 'help' for more info.
Cat5000> (enable)
一些快捷键如下:
Ctrl-A:跳转到命令行的第一个字母
Ctrl-B或左方向键:把光标向左移动1个字母
Ctrl-C:退出
Ctrl-D:删除光标处的文字
Ctrl-E:跳转到命令行末端
Ctrl-F或右方向键:把光标向右移动1个字母
Ctrl-K:删除光标到该行末尾的内容
Ctrl-L;Ctrl-R:另起1行,重复当前命令

Esc-F:把光标向前移动一个单词
设置终端命令为24行,如下:
Cat5000> (enable) set length 24
Screen length for this session set to 24.
Cat5000> (enable)

当交换机初次启动,或者配置文件被擦除以后,交换机会出现登陆密码提示,如下:
Cisco Systems Console

Enter password:
默认口令为回车键,输入后进到用户模式,提示符为console>,输入enable命令进如特权模式,提示符变为console>(enable).在特权模式下,可以通过set等命令对交换机的配置进行修改.set命令相当于IOS里的配置模式

当登陆到交换机的时候,会有banner信息提示,最常用的banner信息就是MOTD(message of the day),命令如下:
Cat5000> (enable) set banner motd [beginning delimiter]
motd banner
[end delimiter]
delimiter前后必须一样

交换机有个令人烦恼的功能,自动注销功能:当你在一定时间内无任何动作,即所谓的空闲(idle),用户将自动注销登陆,默认这个空闲时间为5分钟,修改这一默认时间的命令为set logout [min],例子如下:
Cat5000> (enable) set logout 20
Sessions will be automatically logged out after 20 minutes of idle time.
Cat5000> (enable)

默认的波特率(baud rate)为9600,可以通过如下命令进行修改:
Cat5000> (enable) set system baud [baud rate]
可选baud rate为600,1200,2400,4800,9600,19200和38400

当有一点令人觉得讨厌的是,当你在console工作的时候,终端信息将时不时的显示出来,打断你的命令输入(即,输入到一半,命令被终端信息给分离打断了).可以使用set logging命令用来配置该信息的格式和位置,默认是发送终端信息到console,如下:
Cat5000> (enable) set logging console enable
System logging messages will be sent to the console.
Cat5000> (enable)
再次输入set logging console enable的时候,终端信息将发送到当前终端会话,如下:
Cat5000> (enable) set logging console enable
System logging messages will be sent to the current login session.
Cat5000> (enable)
把logging文件存放在TFTP服务器上,并且服务器的IP地址为172.16.1.10,如下:
Cat5000> (enable) set logging server enable
System logging messages will be sent to the configured syslog
servers.
Cat5000> (enable) set logging server 172.16.1.10
172.16.1.10 added to System logging server table.
Cat5000> (enable)
参观当前logging设置,如下:
Cat5000> (enable) show logging
Logging console: enabled
Logging server: enabled
{172.16.1.10}
Current Logging Session: enabled

设置初始的用户模式的密码,使用set password命令,然后将提示输入旧密码,接着输入2次新密码,如下:
Cat5000> (enable) set password
Enter old password: [old user mode password]
Enter new password: [new user mode password]
Retype new password: [new user mode password]
Password changed.
Cat5000> (enable)
设置特权模式的密码,使用set enablepass命令,如下:
Cat5000> (enable) set enablepass
Enter old password: [old enable password]
Enter new password: [new enable password]
Retype new password: [new enable password]
Password changed.
Cat5000> (enable)
给交换机设置主机名,使用set system name命令,如下:
console> (enable) set system name yUmi520
System name set.
yUmi520> (enable)

注意上面输出中的斜线部分那行的MAC地址范围是supervisor engine(slot1)的MAC地址范围,将用于sc0的BOOTP和ARP请求
配置sc0接口的路由使用set ip route命令,如下:
Cat5000> (enable) set ip route [destination-network] [gateway-address]
例子,创建到网络172.16.2.0的路由,并指定172.16.1.1作为网关.如下图:

Console> (enable) set ip route 172.16.2.0 172.16.1.1
Route added.
但是这个命令有个问题是,它只指定了到达网络172.16.2.0的路由,假如该网络包含其他内网或Internet的话,手动一个个的指定是比较麻烦的.于是,多数情况下,为了方便,都会使用如下命令:
Cat5000> (enable) set ip route default [default-gateway-address] [primary]
其中可选参数primary为当存在多个网关的时候,指定其中1个为主网关.如果指定了多个网关,但是没有使用primary参数的话,最后输入的那个网关作为主网关.当主网关出问题以后,交换机会自动查找备用网关.最多可以配置3个默认网关,除了Catalyst 4000和Catalyst 2926G只能配置1个.例子如下图:

Cat5000> (enable) set ip route default 172.16.1.1 primary
Route added.
Cat5000> (enable) set ip route default 172.16.1.2
Route added.
验证配置的路由信息使用show ip route命令,如下:
Cat5000> (enable) show ip route
Fragmentation    Redirect     Unreachable
––––––   ––––     ––––
enabled         enabled        enabled
The primary gateway: 172.16.1.1
Destination      Gateway        Flags       Use      Interface
––––––   ––––      ––––   –––     ––––
default         172.16.1.1        G          0          sc0
default         172.16.1.2        G          0          sc0
172.16.1.0      172.16.1.5         U         0          sc0
default          default          U H        0          sl0
Cat5000> (enable)
如果你要从sc0的路由表中清除一条路由或网关的话,使用如下命令:
Cat5000> (enable) clear ip route default 172.16.1.2
Route deleted.
Cat5000> (enable) show ip route
Fragmentation    Redirect     Unreachable
––––––   ––––     ––––
enabled         enabled        enabled
The primary gateway: 172.16.1.1
Destination      Gateway        Flags       Use      Interface
––––––   ––––      ––––   –––     ––––
default         172.16.1.1        G          0          sc0
default         172.16.1.2        G          0          sc0
default          default          U H        0          sl0

IP permit list是包含了允许访问sc0口的IP地址,这样增加了安全性,默认这一特性是关闭的,设置IP permit list的步骤如下:
1.启用或关闭IP permit list:
Cat5000> (enable) set ip permit [enable | disable]
2.设置允许访问sc0的IP地址:
Cat5000> (enable) set ip permit [ip_address subnet-mask]
3.验证IP permit list:
Cat5000> (enable) show ip permit
例子,允许节点172.16.3.10和网络172.16.2.0内的所有节点访问sc0,如下图:

Cat5000> (enable) set ip permit enable
IP permit list enabled.
WARNING!! IP permit list has no entries.
Cat5000> (enable) set ip permit 172.16.3.10
172.16.3.10 added to IP permit list.
Cat5000> (enable) set ip permit 172.16.2.0 255.255.255.0
172.16.2.0 with mask 255.255.255.0 added to IP permit list.
Cat5000> (enable)
接下来验证IP permit list,如下:
Cat5000> show ip permit
IP permit list feature enabled.
Permit List          Mask
––––––    –––––
172.16.3.10
172.16.2.0        255.255.255.0

––––––    –––––––––      –––––
172.16.3.1          03/20/99,12:45:20          Telnet
Cat5000>
要清除IP permit list中的某条条目或者所有条目,使用如下命令:
Cat5000> (enable) clear ip permit [ip_address or all] [subnet-mask(if necessary)]
例子:
Cat5000> (enable) clear ip permit all
IP permit list cleared.
WARNING!! IP permit list is still enabled.
Cat5000> (enable)

配置交换机使用DNS服务器,使用set ip dns命令,首先要启用DNS,如下:
Cat5000> (enable) set ip dns enable
DNS is enabled.
Cat5000> (enable)
默认是disable的,接下来设置DNS服务器的IP地址,如下:
Cat5000> (enable) set ip dns server 172.16.1.6
198.92.30.32 added to DNS server table as primary server.
Cat5000> (enable) set ip dns server 172.16.1.7
171.69.2.132 added to DNS server table as primary server.
Cat5000> (enable) set ip dns server 172.16.1.8 primary
171.69.2.143 added to DNS server table as primary server.
DNS服务器表里的条目最多可以有3条,参数primary指定该地址为主要的DNS服务器地址
可以使用show ip dns查看当前DNS设置,如下:
Cat5000> show ip dns
DNS is currently enabled.
The default DNS domain name is: ar-inc.com
DNS name server        status
–––––––       –––
172.16.1.6
172.16.1.7             primary
172.16.1.8
Cat5000>
还可以设置主机表,使用set ip alias命令,如下:
Cat5000> (enable) set ip alias [name] [ip_address]
该命令添加一条条目到主机表中
验证主机表使用show ip alias [name]命令.例子如下:
Cat5000> (enable) set ip alias Cat-1 172.16.1.1.
IP alias added.
Cat5000> (enable) set ip alias Cat-2 172.16.1.2
IP alias added.
Cat5000> (enable) set ip alias Cat-3 172.16.1.3
IP alias added.
Cat5000> (enable) set ip alias Cat-4 172.16.1.4
IP alias added.
Cat5000> (enable) show ip alias
default       0.0.0.0
cat-1        172.16.1.1
cat-2        172.16.1.2
cat-3        172.16.1.3
cat-4        172.16.1.4
Cat5000> (enable)
上面输出里的default 0.0.0.0通常代表默认路由

为了能够远程拨号访问交换机,sl0接口允许在sonsole口上建立SLIP(Serial Line Internet Protocol)连接.使用set interface sl0来配置sl0口运行SLIP,如下:
Cat5000> (enable) set interface sl0 [slip_address] [destination_address]
如果要使得console口接受SLIP呼叫的话,还要使用slip attach命令.例子如下:
Cat5000> (enable) set interface sl0 172.16.1.1 172.16.1.2
Interface sl0 slip and destination address set.
Cat5000> (enable) slip attach
Console Port now running SLIP.
可以使用show interface命令,查看sl0和sc0口的汇总信息,如下:
sl0: flags = 51
slip 172.16.1.1 dest 172.16.1.2
sc0: flags = 63
vlan 1 inet 172.16.100.1 netmask 255.255.255.0 broadcast
172.16.100.255
Cat5000> (enable)

用reset system命令,当然也可以简写为reset.当然也可以单独的重启某个模.比如重启slot3上的line card,如下:
Cat5000> (enable) reset 3
This command will reset module 3 and may disconnect your telnet session.

Do you want to continue (y/n) [n]? y
Resetting module 3 . . .
Cat5000> (enable) 04/06/1999,18:53:35:SYS-5:Module 3 reset from telnet/172.16.1.5/
Cat5000> (enable) 04/06/1999,18:53:57:SYS-5:Module 3 is online

the Configuration File

Catalyst 5000不像路由器,配置文件不存在running-config和startup-config之分,当RAM中的配置文件变动以后,自动同步到NVRAM中去.配置文件是以文本文件的形式保存的,可以使用show config命令查看配置文件

Backing Up and Restoring a Configuration File

对于supervisor engine I和II,把配置文件备份到TFTP服务器上,使用write network命令,如下:
Cat5000> (enable) write network
IP address or name of remote host? 172.16.1.10
Name of configuration file?tch.txt
Upload configuration to config-file-name on address (y/n) [n]? y
. . . . .
. . . . . . . . . .
. . . . . . . . . .
. .
/
Finished network upload. (124356 bytes)
Cat5000> (enable)
对于supervisor engine III或者Catalyst 4000,使用copy config tftp命令,如下:
Cat5000> (enable) copy config tftp
IP address or name of remote host? 172.16.1.10
Name of configuration file?tch.txt
Upload configuration to config-file-name on address (y/n) [n]? y
. . . . .
. . . . . . . . . .
. . . . . . . . . .
. .
/
Finished network upload. (124356 bytes)
Cat5000> (enable)
要从TFTP服务器上恢复备份配置文件的话,对于supervisor engine I和II,使用configure network命令,如下:
Cat5000> (enable) configure network
IP address or name of remote host []? 172.16.1.10
Name of file to copy from []?tch.txt
Configure using tftptch.txt (y/n) [n]? y
/
Finished network download. (124356 bytes)
对于supervisor engine III或Catalyst 4000,使用copy tftp config命令,如下:
Cat5000> (enable) copy tftp config
IP address or name of remote host []? 172.16.1.10
Name of file to copy from []?tch.txt
Configure using tftptch.txt (y/n) [n]? y
/
Finished network download. (124356 bytes)
要注意的是这些是supervisor engine的配置文件而不是RSM或ATM LANE card的配置文件.这些模块运行的是IOS并且有着自己的配置文件

Managing the Catalyst IOS Files

对CatOS的版本进行升级,推荐根据以下几个步骤进行升级:
1.先决定你要进行升级的版本号
2.建立一个TFTP服务器,把新的CatOS放在特定目录
3.备份当前旧的CatOS.可以使用show version命令查看版本号.如下:
Cat5000> (enable) sh ver
WS-C5000 Software, Version McpSW: 4.3(1a) NmpSW: 4.3(1a)
Copyright (c) 1995-1998 by Cisco Systems
NMP S/W compiled on Nov 23 1998, 15:22:34
MCP S/W compiled on Nov 23 1998, 15:19:30
System Bootstrap Version: 3.1.2
Hardware Version: 2.0 Model: WS-C5000 Serial #: 010847706
(略)
备份到TFTP服务器上,对于supervisor engine I和II,使用upload命令,对于supervisor engine III,使用copy flash tftp命令.如下:
Cat5000> (enable) upload 172.16.10.1 sup-412a.img
Upload Module 1 image to sup-412.img on 172.16.10.1 (y/n) [n]?
y -
Finished network upload. (2718432 bytes)
Cat5000> (enable)
4.从TFTP服务器上下载新的CatOS镜象文件,对于supervisor engine I和II,使用download命令,对于supervisor engine III,使用copy tftp flash命令.如下:
Cat5000> (enable) copy tftp flash
Upload Module 1 image to sup-412.img on 172.16.10.1 (y/n) [n]?
y -
Finished network upload. (2718432 bytes)
Cat5000> (enable)
5.至此新的CatOS已经下载到Flash中去了,使用reset命令重启交换机,升级过程完毕
要注意的是supervisor engine I和II只有1个区域用来存放闪存,但是对于supervisor engine III,有3个区域,如下图:

复制文件的语法如下:
Cat5000> (enable) copy [source-memory-area]:[file-name] [destination-memory-area]
复制的过程中还可以定义新的文件名,如下:
Cat5000> (enable) copy [source-memory-area]:[file-name] [destination-memory-area]:[new-name]
例子如下图:

Cat5000> (enable) copy bootflash:sup-412a.img slot0:
Supervisor engine III还有个特性是闪存区域还可以存放配置文件,如下:
Cat5000> (enable) copy config flash
Flash device [bootflash]? bootflash:
Name of file to copy to [test_image]?tch.txt
Upload configuration to bootflashtch.txt
678324 bytes available on device slot1, proceed (y/n) [n]? y
. . . . . . . . .
. . . . . . . . .
. . . . . . . . .
. . . . . . . .
.
/
Configuration has been copied successfully. (175664 bytes).
Cat5000> (enable)

the Boot System Command

可以使用set boot system命令来定义启动时加载的文件,如下:
Cat5000> (enable) set boot system flash [memory area]:[filename]
比如,要让交换机下次启动的时候,从slot0的PCMCIA卡加载sup3-441.img到操作系统中去,如下:
Cat5000> (enable) set boot system flash slot0:sup3-441.img

Configure the Ethernet, FastEthernet, and Gigabit Ethernet Ports

可以给Ethernet,FastEthernet和Gigabit Ethernet端口分配一个名字,使用set port name命令,如下:
Cat5000> (enable) set port name [module_number/port_number] [name_string]
例子如下:
Cat5000> (enable) set port name 1/1 Connection to Backbone Catalyst 5500
Port 1/1 name set.
端口到背板的访问由port priority或port level决定,3种级别为high,normal和critical.critical是不可设置的,默认级别为normal.设置命令如下:
Cat5000> (enable) set port level [module_number/port_number] [normal | high]
例子如下:
Cat5000> (enable) set port level 1/1 high
Port 1/1 level set to high.
Cat5000> (enable)
有的line card同时支持10Mbps和100Mbps,可以使用set port speed来指定速率,或者让它自动与对方协商,决定自身速率.,命令如下:
Cat5000> (enable) set port speed module_number/port_number [10/100/auto]
例子如下:
Cat5000> (enable) set port speed 1/1 100
Port 1/1 speed set to 100 Mbps.
Cat5000> (enable)
对于只支持10Mbps或100Mbps的Ethernet和FastEthernet的双工模式的设置(Gigabit Ethernet不支持半双工),使用set pot duplex命令,如下:
Cat5000> (enable) set port duplex module_number/port_number [full | half]
例子如下:
Cat5000> (enable) set port duplex 1/1 full
Port 1/1 set to full-duplex.
Cat5000> (enable)
对于同时支持10Mbps或100Mbps的端口,默认双工模式为auto,并且这个是和端口速率的关系是绑定了的,如果端口速率设置为auto,双工模式即为auto;如果端口速率设置为10Mbps或100Mbps,双工模式默认为半双工,但是可设置成全双工
使用show port命令对设置进行验证,如下:

Working with STP

修改桥的优先级,使用set spantree priority命令,默认是32765.优先级值低的选作根桥.如下:
Cat5000> (enable) set spantree priority [bridge_priority] [vlan]
如果没有定义VLAN,默认是VLAN 1
如下,设置VLAN 10的根桥:
Cat5000> (enable) set spantree priority 1 10
端口作为转发端口的几个因素:port cost和port priority.设置特定某个VLAN的port cost,命令如下:
Cat5000> (enable) set spantree portvlancost [module_number/port_number] cost [cost] [VLAN]
设置所有VLAN,如下:
Cat5000> (enable) set spantree portcost [module_number/port_number] [cost]
例子,设置所有的VLAN的port cost为10,如下:
Cat5000> (enable) set spantree portcost 1/1 10
Spantree port 1/2 path cost set to 10.
设置VLAN 1中的port cost为10,如下:
Cat5000> (enable) set spantree portvlancost 1/2 cost 10 1
Port 1/1 VLANs 2-1005 have path cost 19.
Port 1/1 VLANs 1 have path cost 10.
Cat5000> (enable)
默认所有端口的port priority的值为32,范围是1到63,值越低,就越容易被选为转发端口
设置优先级的命令,对于所有的VLAN,命令如下:
Cat5000> (enable) set spantree portpri mod_num/port_num priority [vlans]
对于特定VLAN,如下:
Cat5000> (enable) set spantree portvlanpri mod_num/port_num priority [vlans]
例子,设置对于所有VLAN,端口2/1的优先级为1:
Cat5000> (enable) set spantree portpri 2/1 1
Bridge port 2/1 port priority set to 1.
Cat5000> (enable)
设置对于VLAN 1,端口2/1的优先级为1,如下:
Cat5000> (enable) set spantree portvlanpri 2/1 1 10
Port 2/1 vlans 1-9,11-1005 using portpri 32.
Port 2/1 vlans 10 using portpri 1
Cat5000> (enable)
在端口处于学习和监听的时候启用转发,如下:
Cat5000> (enable) set spantree portfast [module_number/port_number] [enable | disable]
例子,比如端口2/1和服务器直接相连,这就没必要在端口学习和监听的时候对端口进行block,如下:
Cat5000> (enable) set spantree portfast 2/1 enable
Warning: Spantree port fast start should only be enabled on ports connected to a single host. Connecting hubs, concentrators,tches, bridges, etc. to a fast start port can cause temporary spanning tree loops. Use with caution.
Spantree port 2/1 fast start enabled.
这些参数可以通过show spantree命令来查看,如下:
Cat5000> (enable) show spantree [module/number] [vlan_number]
例子:
Cat5000> (enable) show spantree 2/1
