These release notes describe the new features and caveats in the EtherSwitch 1420 and the EtherSwitch 1220 Version 5.34 firmware. This firmware runs on the EtherSwitch 1420 and EtherSwitch 1220.
The product documentation for the EtherSwitch 1420 and EtherSwitch 1220 is as follows:
EtherSwitch 1420 Series and EtherSwitch 1220 Series Installation and Configuration Guide
EtherSwitch 1420 Modules User Guide
EtherSwitch 1420 Series and EtherSwitch 1220 Series MIB Reference Manual
This version adds automatically-refreshed statistics. If you are using VT100 terminal emulation, screens displaying statistics are refreshed every 5 seconds.
The following modification is included in Version 5.34:
When port monitoring is enabled with port B as the monitor port, no packets from the ports being monitored are sent to it. Version 5.34 fixes this problem.
This section lists possibly unexpected behavior by Version 5.34.
An RS-232 cable that is connected to a switch-but not connected to a device at the other end-might cause the switch to reset.
If you have customized any Version 5.25 parameters, the upgrade to Version 5.34 resets these parameters to their factory default values. Reset them to your customized settings after the upgrade. (The 5.34 default values of the configurable parameters have not changed from Version 5.25.)
The following parameters return to the listed factory default values when you upgrade to Version 5.34 from 5.25.
