The management port on the switch router allows multiple simultaneous Telnet or SNMP network management sessions. Since there is no separate management port on the Layer 3 switch routers, you can configure any Fast Ethernet or Gigabit Ethernet port as a management port.
You can remotely configure the switch router through the management port, but first you must configure an IP address so that the switch router is reachable. You can manually configure the management port interface from the command-line interface (CLI).
Note - Before you begin to configure the management port interface manually, obtain the switch router's IP address and IP subnet mask. Also make sure the console cable is connected to the console port.
You can configure the management port from an IP connected network. To obtain remote management access using Telnet, use the following steps:
| |
Command |
Purpose |
Step 1 |
Router> enable
Router# |
Enters enable mode.
The # prompt indicates enable mode. |
Step 2 |
Router# configure terminal
Router>
|
Enters global configuration mode. You can also abbreviate the command to config terminal. The Router(config)# prompt indicates that you are in global configuration mode. |
| Step 3 |
Router(config)#enable passwordRouter(config)# password
|
Sets the enable password. See the "About Passwords" section. |
Step 4 |
enable secretRouter(config)# password |
Enters an enable secret password. Once set, a user must enter the enable secret password to gain access to global configuration mode. |
Step 5 |
interfacetype number
Router(config)#
|
Enters interface configuration mode on the Ethernet interface.
You can use any Fast Ethernet interface 1-48 or any Gigabit Ethernet interface 49-50 on the Catalyst 2948G-L3 or any Gigabit Ethernet interface 1-8 on the Catalyst 4908G-L3 to configure the management port. |
Step 6 |
Router(config-if)#ip addressip-address subnetmask
|
Enters the IP address and IP subnet mask for the interface specified in Step 5. |
| Step 7 |
Router(config-if)# no shutdown
|
Enables the interface. |
| Step 8 |
Router(config-if)# exit
Router(config-if)#
|
Returns to global configuration mode. |
| Step 9 |
Router(config)#line vty line-number
Router(config)# (Router)config-line
|
Enters line configuration mode for virtual terminal connections. Commands entered in this mode control the operation of Telnet sessions to the switch router. |
Step 10 |
Router(config-line)# password password |
Enters a password for Telnet sessions. |
Step 11 |
Router(config-line)# end
Router# |
Returns to privileged EXEC mode. |
Step 12 |
# copy running-config startup-config
|
Saves your configuration changes to NVRAM. |
| Note - Any Fast Ethernet interface 1-48 and any Gigabit Ethernet interface 49-50 on the Catalyst 2948G-L3 switch router, or any Gigabit Ethernet interface 1-8 on the Catalyst 4908G-L3 switch router, can be configured as a management port. |
Your switch router should now be operating correctly. You can now use Telnet to remotely assign and verify configurations.
You can display the configuration file when you are in privileged EXEC (enable) mode.
To see the current operating configuration, enter the following command at the enable prompt:
Router# show running-config
To see the configuration in NVRAM, enter the following command:
Router# show startup-config
If you made changes to the configuration, but did not yet write the changes to NVRAM, the results of the show running-config will differ from the results of the show startup-config command.
