Cisco Systems RJ-45-to-AUX manual Enter Global Configuration mode with the following commands, 125

Router>

3. Enter Global Configuration mode with the following commands:

Router> enable

Router# configure terminal

Warning When you make changes in this mode, they must be saved to NVRAM. Otherwise, the next time you recycle the switch, the changes will be lost. The command to save changes is copy running−config startup−config.

4. Assign the RSM a unique hostname with the following command. Call it RSM1:

Router>(config)# hostname RSM1

RSM1>(config)#

Tip	The hostname can be up to 255 characters, using alphanumeric characters only. Although in this
	example we use uppercase to identify the hostname, in some instances when you connect to the
	switch with different software, the hostname may appear in lowercase.

Assigning an IP Address and Encapsulation Type to an Ethernet Interface

To assign an IP address and a trunking encapsulation type to an Ethernet interface so interVLAN routing can take place, follow these steps:

1.To enter Interface Configuration mode for Ethernet on the subinterface that needs to be configured, enter the following command in Global Configuration mode:

Catalyst5000(config)#interface ethernet 3/1.2

In this example, 3 indicates the module number/slot number, 1 indicates the port number, and 2 indicates the number of the subinterface to be configured.

Note No changes take effect until the no shutdown command is issued.

2.Once in Interface Configuration mode, you can configure the port for the encapsulation type and identify the VLAN number that will be carried by the port. The most common encapsulation type is ISL; this will be the encapsulation type configured in our example. Configure the interface for VLAN 2. Each VLAN packet destined for a non−local network is tagged with a VLAN ID within the packet header, to help identify the VLAN to the subinterface:

Coriolis5000(config−if)#encapsulation isl 2

3.Assign the subinterface its own unique IP address and subnet mask. To do this, use the following commands followed by a no shutdown command to apply the changes and exit:

Coriolis5000(config−if)#ip address 130.77.20.18 255.255.254.0

Coriolis5000(config−if)#no shutdown

Coriolis5000(config−if)#exit

Setting the Port Speed and Port Name on an Ethernet Interface

Here is an example of setting the port speed and port name:

Coriolis5000> (enable) set port speed 2/3 auto

Port 2/3 speed set to auto detect.

Coriolis5000> (enable) set port name 2/3 VLAN 1 FileServer1

Port 2/3 name set.

Coriolis5000> (enable) show port 2/3

Port Name Status Vlan Level Duplex Speed Type
