vci vci   

Virtual Circuit Identifier. In order to modify, the VCI 
value shall be the new VCI value and the admin 
status of VC interface shall be disabled. Also, the 
VPI and VCI valaue cannot be modified along with 
admin status in one command.   
Type :  Create – Mandatory Modify – Optional 
Valid values : 1-2^16   

mgmtmode Data | Mgmt |   
DataAndMgmt | Raw   

It denotes the Management Mode of the ATM VC. 
If it is Data, then only data transmission can take 
place. If it is Mgmt, then management of remote 
CPE device can happen on that ATM VC and 
packets on that ATM VC shall start coming to 
Control Plane. In DataAndMgmt mode, data 
transmission as well as remote CPE management 
can happen on the same ATM VC interface. In 
DataAndMgmt mode, the only acceptable value for 
atmVCCAAL5EncapType is llc. In Mgmt mode, 
EoA interface cannot be created on the ATM VC 
and both Ethernet as well as non-ethernet packets 
on that ATM VC shall be received at the Control 
Plane. In DataAndMgmt mode, if EoA is created, 
then only non-ethernet packets on that ATM VC 
shall be received at the Control Plane. However, if 
EoA is not created then all the packets on that 
ATM VC shall be received at the Control Plane. 
However, to configure ATM VC in DataAndMgmt 
mode, a good practice is to to create ATM VC in 
disable mode till EoA is created on it, to prevent 
flooding at Control Plane. In order to run STP, the 
mode has to be DataAndMgmt. If the mode is 
RawATM(4), ATM cells    are given to Control 
Plane. In this mode, EoA interface can ot be 
created on the ATM VC. If EoA interface is already 
created on the ATM VC, its mode cannot be 
changed to either Mgmt(2) or RawATM(4).   
Type :  Create  Optional  
Default value: Data   

enable|disable   

This specifies the Admin Status of the VC.   
Type : Optional   
Default Value: enable   

aal5   

This specifies the AAL type in use for this VC. The 
only type of AAL supported in Columbia Packet is 
AAL5.  
Type: The only value to be supported is aal5. 
Default value : aal5   

a5txsize 
aal5-cpcs-tx-sdu-size   

This specifies the maximum transmit CPCS SDU 
size to be used.   
Type : Optional   
Valid values : 
1-GS_CFG_ATM_VC_MAX_RX_PDU_SIZE   
Default Value:  
GS_CFG_ATM_VC_DEF_TX_PDU_SIZE   

a5rxsize 
aal5-cpcs-rx-sdu-size   

This specifies the maximum receive CPCS SDU 
size to be used   
Type : Optional   
Valid values : 
1-GS_CFG_ATM_VC_MAX_TX_PDU_SIZE   
Default Value:  
GS_CFG_ATM_VC_DEF_TX_PDU_SIZE   

vcmux|llcmux   

This specifies the data multiplexing method to be 
used over the AAL5 SSCS layer.   
Type : Optional   
Default Value: llcmux   

Pvc   

This specifies the type of VC. The only value 
supported is PVC.   
Type : Optional
