AT-S25 Version 1.5.6 Software Release Notes
PN 613-50303-00 Rev A 7 Allied Telesyn, Inc.
• Statistic Counters
Alignment errors and CRC errors are reported in the same counter.
• RMON and Uplink Ports
RMON alarms and the RMON log are not generated for uplink ports.
• BOOTP File Transfers
This version of the management software does not support file transfers from a BOOTP
server. Consequently, you cannot use a BOOTP server to download a new version of the
AT-S25 software onto an AT-8300 Series stack. However, you can use a BOOTP server to
configure the IP parameters of a stack.
• Static Multicast Addresses
This version of the management software does not support static multicast addresses. The
Omega interface contains menu selections for entering static multicast addresses, but the
menu selections have been disabled.
• Fast Switch MIB
Some MIB objects in the Fast Switch MIB (FSTSWITCH.MIB) are not accessible due to time-
out problems.
• Ping Byte Length
The switch cannot accept a ping exceeding 1472 bytes.
Previous Versions
Resolved Issues
• Stack Boot Up Times
The time required for a stack to begin forwarding Ethernet packets when power cycled or
reset has been significantly reduced. The boot up and initialization process for a stack of
one switch takes approximately 1 1/2 minutes, while the same process for a stack of four
switches takes approximately 3 minutes. If the master switch needs to download new
software onto the slave switches in a stack of 4 switches, the entire boot up, download and
initialization process takes only 4 to 5 minutes.
• Deleting VLANs Without Ports
Previous versions of the management software did not allow you to delete a VLAN if it did
not have any tagged or untagged ports. This problem has been resolved.
• Virtual LANs (VLANs)
VLANs can now be created or modified during periods of heavy network traffic.
