TCP/UDP Port Closure

In earlier software releases, certain UDP ports were always open. Beginning with software release
M.10.04, all TCP/UDP ports on the 3400cl switches will remain closed until the associated services
are enabled on the switch.
The following ports and services are affected by this change:
Port Service
69 TFTP
161 SNMP
520 RIP
1507 Stacking (SNMP)
To open any of these ports, the respective services must first be enabled on the switch. For
information on how to enable/disable these services, refer to the following command listings . For
details on each service, refer to the latest version of the switch's software documentation available
on the ProCurve Networking Web site.
