DETAILED STEPS
Configuring ADSL or VDSL on Cisco Multi Mode 886VA and 887VA ISRs
The Cisco customer premise equipment (CPE) 886VA and 887VA integrated services routers (ISRs)
support asymmetric digital subscriber line (ADSL) 1/2/2+ and very high speed digital subscriber line 2
(VDSL2) transmission modes, also called multi mode. The 886VA supports xDSL over ISDN and the
887VA supports xDSL over a plain old telephone system (POTS).
The default CPE operating mode is auto. Auto mode means that the CPE trains up to the mode configured
on the digital subscriber line access multiplexer (DSLAM), ADSL1/2/2+ or VDSL2.
Command Purpose
Step 1
controller vdsl 0
Example:
Router# config t
Router(config)# controller vdsl 0
Enters controller configuration mode and the
controller number.
Note There is no need to configure any
VDSL2 parameters from CPE side.
Any specific VDSL2 settings should
be set on the DSLAM side.
Step 2
interface type number
Example:
Router(config)# interface ethernet 0
Router(config-if)#
Enters the configuration mode for Ethernet
Layer 2 transport on the VDSL WAN interface
on the router.
Step 3
ip address ip-address mask
Example:
Router(config-if)# ip address 192.168.12.2
255.255.255.0
Router(config-if)#
Sets the IP address and subnet mask for the
interface.
Step 4
shutdown
Example:
Router(config-if)# no shutdown
Router(config-if)#
Disables the interface, changing its state from
administratively up to administratively down.
Step 5
no shutdown
Example:
Router(config-if)# no shutdown
Router(config-if)#
Enables the interface, changing its state from
administratively down to administratively up.
Step 6
exit
Example:
Router(config-if)# exit
Router(config)#
Exits configuration mode and returns to global
configuration mode.
