Visara CNA-8000 Planning Guide - Manual (Page 50)

Chapter 5. Migrating from 1174 or 3174
5-12 707156-002
Notes:
1)
Ports on the 1174 are defined per interface. Ports on the CNA-8000 are defined
across all of the interfaces defined for TN3270 use.
2) Ports on the CNA-8000 are currently limited starting at port 1026 to reduce port
conflicts with other IP protocols. If you need to use ports below that, contact your
Visara Representative.
3) The CNA-8000 supports encryption directly to the client when configured. The
1174 required external encryption such as through the SSL-1000. Migrating from
no encryption on the 1174 to using encryption on the CNA-8000 requires a
reconfiguration of the client desktops.
4) Encryption on the CNA-8000 is configurable on a port by port basis.
