Updating the ATM Virtual Channel Link
The Z-Edge 64 automatically creates an atm-vcl profile for the WAN port
when it is turned on. The atm-vcl profile specifies the Virtual Path Identifier/
Virtual Channel Identifier (VPI/VCI) pair for the ATM virtual channel link
(VCL). The default atm-vcl record on the WAN interface specifies data traffic
(AAL5) over the 0/35 VPI/VCI pair.
Note:
You cannot modify an active VCL. If you want to make
changes to the atm-vcl profile, you must first change the
admin_status to down and save the updated record.
The following table list the parameters of the default atm-vcl profile:
The example below shows the default atm-vcl record created by the system:
zSH> get atm-vcl 1-1-1-0-hdsl2/atm/0/35
vpi: -----------------------------> {0}
vci: -----------------------------> {35}
admin_status: --------------------> {up}
receive_traffic_descr_index: -----> {1}
transmit_traffic_descr_index: ----> {1}
vcc_aal_type: --------------------> {aal5}
vcc_aal5_cpcs_transmit_sdu_size: -> {9188}
