Asynchronous Group Interface Examples
The following example shows how to create an asynchronous group interface 0 with group interface
members 2 through 7, beginning in global configuration mode:
interface group-async 0
group-range 2 7
The following example shows how you need to configure asynchronous interfaces 1, 2, and 3 separately
if you do not have a group interface configured:
interface Async1
ip unnumbered Ethernet0
encapsulation ppp
async default ip address 172.30.1.1
async mode interactive
async dynamic routing
!
interface Async2
ip unnumbered Ethernet0
encapsulation ppp
async default ip address 172.30.1.2
async mode interactive
async dynamic routing
!
interface Async3
ip unnumbered Ethernet0
!
encapsulation ppp
async default ip address 172.30.1.3
async mode interactive
async dynamic routing
The following example configures the same interfaces, but from a single group asynchronous interface:
interface Group-Async 0
ip unnumbered Ethernet0
encapsulation ppp
async mode interactive
async dynamic routing
group-range 1 3
member 1 async default ip address 172.30.1.1
member 2 async default ip address 172.30.1.2
member 3 async default ip address 172.30.1.3
Modem Asynchronous Group Example
To configure a group asynchronous interface, specify the group async number (an arbitrary number) and
the group range (beginning and ending asynchronous interface number).
The following example shows the process of creating and configuring a group asynchronous interface
for asynchronous interfaces 1 through 96 on a Cisco AS5300 access server, which is loaded with
ninety-six 56K MICA technologies modems:
interface group-async 1
ip unnumbered ethernet 0
encapsulation ppp
async mode interactive
