Configure VDSL
The following table provides usage information and guidelines for configuring asymmetric DSL (ADSL2/2+) and VDSL for supported Integrated Services Router Network Interface Modules (ISR NIMs) in SD-WAN mode. VDSL2 and ADSL2/2+ provide highly reliable WAN connections for remote sites.
For related information, see VDSL Commands.

Guidelines |
---|---|---|
Configure operating mode |
Device# configure terminal Device(config)# controller VDSL slot/subslot/port Device(config)# operating mode auto |
To switch from operating mode auto adsl1 (adsl2+/ or vdsl2) to operating mode auto ads2+ (adsl1 or vdsl2), switch to operating mode auto first. Before you change the operating mode, ensure that line-mode is changed to line-mode single-wire line 0. |
Enable DSL on a line |
Device(config)# line-mode single-wire lineline-number |
This command is supported only on DSL NIM-VAB-A. |
Enable bonding |
Device(config)# line-mode bonding |
This command is supported only on DSL NIM-VAB-A. |
Load firmware on a device |
Device# configure terminal Device(config)# controller VDSL slot/subslot/port Device(config-controller)# firmware phy filename filename |
The Cisco Catalyst SD-WAN CLI template does not support specifying the file location. Prepend the file name with flash: or with bootflash:, depending on its location. |
Enable or disable SRA |
Device(config-controller)# sra |
The Cisco Catalyst SD-WAN CLI template does not support the sra line number command. In line-mode bonding, sra enables sra on both lines and no sra disables sra on both lines. |
Enable or disable bitswap |
Device(config-controller)# bitswap |
The Cisco Catalyst SD-WAN CLI template does not support the bitswap line number command. In line-mode bonding, bitswap enables bitswap on both lines and no bitswap disables bitswap on both lines. |
Enable modem features |
Device(config-controller)# modemkeyword |
– |
Display a description of a controller |
Device(config-controller)# description string |
– |
Enable dual ended line testing |
Device(config-controller)# diagnostics DELT |
– |
Modify the file in which the training log is stored |
Device(config-controller)# training log filename flash: filename |
The Cisco Catalyst SD-WAN CLI template does not support specifying the file location. Prepend the file name with flash: or with bootflash: , depending where the file should be stored. |
Enable sync mode |
Device(config-controller)# sync mode mode |
To switch from one sync mode to another, delete the existing sync mode, then configure the new one. |
Enable sync interval |
Device(config-controller)# sync interval seconds |
– |
