Step 4 Verify that the Fast Ethernet interface is up. Ping the default gateway to verify this.

Gateway# ping 172.28.186.49

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 172.28.186.49, timeout is 2 seconds:

.!!!!

Success rate is 80 percent (4/5), round-trip min/avg/max = 1/1/4 ms

Tip To save the gateway configuration, save it to NVRAM. Refer to the “Saving Configuration Changes” section on page 57

Note An 80 percent ping-success rate is normal for the first time you ping an external device. The universal gateway does not have an Address Resolution Protocol (ARP) entry for the external device. A 100 percent success rate is achieved the next time you ping the device.

Configuring the Asynchronous Group Interface

This section shows how to configure asynchronous interfaces. Asynchronous group interfaces allow administrators to easily configure a large number of asynchronous interfaces by allowing them to clone from one managed copy. This can also reduce the number of lines in the configuration, because each individual asynchronous interface configuration can be replaced by at least one group-async. To assign the asynchronous interfaces to a group-async interface, first determine the number of asynchronous lines that need to be aggregated. This can be determined from the running configuration.

Step 1 Enter the enable command and password to go to privileged EXEC mode. You are in privileged EXEC mode when the prompt changes to Gateway#.

Gateway> enable

Password: password

Gateway#

Step 2 Enter global configuration mode. You are in global configuration mode when the prompt changes to Gateway(config)#.

Gateway# configure terminal

Enter configuration commands, one per line. End with CNTL/Z.

Gateway(config)#

Step 3 Place all asynchronous interfaces in a single group, so that you configure the same parameters quickly on all interfaces at one time:

Gateway(config)# interface group-async 1

Gateway(config-if)#

Step 4 Define the slot/port group range of the interface. The range that you specify depends on the number of asynchronous interfaces you have on your gateway. If your gateway has 108 asynchronous interfaces, you can specify group-range 1/1 1/107.

Gateway(config-if)# group-rangeslot/port slot/port

Building configuration...

Gateway(config-if)#
