SE/PVC Configuration Parameters
NOTE: If you configure the IP Address parameter, the value of the global Default IP
Address parameter is ignored for this PVC.
5.3.12 Subnet mask (number of bits)
5.3.13 NAT enable
Values: 000.000.000.000 - 255.255.255.255
Default: 000.000.000.000
Console SNMP Text-based Config
Subnet mask (number of
bits)
atmpvcSubnetMask [atmpvc#] SubnetMask
The subnet mask associated with the IP address for this PVC. The Subnet mask identifies
which bits of the IP address correspond to the physical network, and which bits
correspond to host identifiers. For example, in IP address 255.255.000.000 all network
bits are set to 1 and all host bits are set to 0.
To change the value of the subnet mask using the console, enter the number of bits of that
mask.
• For example, select 17 bits to define the mask 255.255.128.000; select 23 bits to
define 255.255.254.000
• When you enter the number of bits at the console, the NetPerformer provides the
resulting mask in dotted decimal notation to the right of the bits value
• For the SNMP interface, you cannot change the number of bits. You must enter
the value of the subnet mask directly.
• If the value of the subnet mask is not valid for the configured IP address, it will
be rejected by the NetPerformer and the IP address will be invalid.
NOTE: As of V10.2 the NetPerformer supports super-netting as well as subnetting. To
accommodate this the subnet mask of any IP address can now be set to any
whole integer value from 0 to 32.
Values: 0 - 32 (equivalent to 000.000.000.000 - 255.255.255.255)
Default: 0 (equivalent to 000.000.000.000)
