An address translation can be one of three types. The type of translation
determines the number of translation entries as shown in
Table 61 - Number of Translation Entries by Translation Type
Translation Translation
Type Entries
Single 1
Range Multiple
Subnet 1
EXAMPLE The following translation types count as 10 translation entries:
• Single translation for one device
• Range translation for eight devices
• Subnet translation for all devices on the subnet
Singe and range translation types have a one-to-one relationship between
translations entries and addresses to be translated. However, subnet
translations have a one-to-many relationship allowing one translation entry
for many addresses.
Table 62 defines the maximum number of translation entries that are allowed
per switch.
