Appendix C Supporting and Using Additional CLI Access Options
Setting Up Dial-Up Connections
Tip
Cisco recommends that you use the same subnet for all IP addresses defined on all MGX 8850
switches. This simplifies router configuration.
Note
There are other options for the ipifconfig command, and you can set one or more options
simultaneously. Any options you do not define in a command remain unchanged. For more
information on this command, refer to the Cisco MGX 8850 (PXM45/PXM1E), Cisco MGX
8950, Cisco MGX 8830, and Cisco MGX 8880 Command Reference, Release 5.
After you complete this procedure, the switch is ready for configuration through the maintenance port.
Configuring the Switch
To support IP connectivity over the ATM interface, you need to do the following tasks:
1.
Assign an IP address to the ATM interface.
2.
Assign an AESA to the ATM interface.
3.
Define an AESA for every adjacent router that supports IP communications to the ATM interface.
4.
Configure ATM communications between the switch and the router.
To configure the switch to support IP connectivity to the ATM interface, use the following procedure.
Step 1
Establish a CLI management session using a username with SUPER_GP privileges. The default user
name and password for this level are superuser, <superuser>.
Step 2
Verify that the IP address for the ATM interface is not already configured by entering the following
command:
mgx8850a.7.PXM.a>
dspipif atm0
Note
If you omit the atm0 option, the switch displays the configuration for all switch IP interfaces:
the ATM interface (atm0), the PXM LAN port interface (lnPci0), and the PXM maintenance port
interface (sl0). Note that the address for each interface must be unique.
In the IP Interface Configuration Table, look for an Internet address entry under the atm entry. If an IP
address is configured, you can use that address. However, if the address has not been entered or is
incompatible with your network, you must configure a valid IP address as described in the next step.
Step 3
To set the switch IP address for the ATM interface, enter the ipifconfig command using the following
format:
mgx8850a.7.PXM.a>
ipifconfig atm0
<
IP_Addr
> <
netmask
Mask
>
Replace <IP_Addr> with the IP address you want this port to use, and replace <Mask> with the network
mask used on this network.
