AT-S60 Version 2.0.0 NE Management Software Release Notes
PN 613-50544-00 Rev B 5 Allied Telesyn, Inc.
Resolved Issues
The following items have been resolved in Version 2.0.0 NE of the AT-S60 management
software.
Hot Swapping Line Cards and Locked Security Level. The switch will stop forwarding traffic
if you remove a line card that has one or more ports operating in the Locked security level. To
avoid this problem, always examine the security level of the ports on a line card before you
disconnect a link or remove a line card from the chassis, and change the security level of any
ports operating in the Locked level.
IGMP Snooping and Leave Requests. The AT-8400 Series switch would not forward leave
requests from host nodes to multicast routers when it is configured with IGMP in multi-host
mode. This could have resulted in situations where the last host node would continue to
receive multicast packets from a multicast router even though all host nodes had been issued
leave requests. This issue has been resolved.
IGMP Snooping Limitation. If your network configuration included a server and a router
connected to two separate ports on the AT-8400 Series switch and you wanted to configure
IGMP snooping on the switch, the router will not receive multicast traffic. This issue has been
resolved.
Locked Security Level. When changing the security level of a port from the Locked level to
either the Limited or Secured level, you were required to first change the port's security level
to Automatic. This issue has been resolved.
Remote File Downloads. The previous version of the AT-S60 management software did not
support downloading a software image or configuration file to the switch from a Telnet
management session. This issue has been resolved.
Static Multicast Addresses and Port Number. The MAC address table did not display the
port number(s) of static multicast MAC address. This issue has been resolved.
Port Trunks and Distribution of Source MAC Addresses. Without RSTP enabled, the source
MAC addresses assigned to the ports of a port trunk were not redistributed when a port was
added or removed from the trunk. This issue has been resolved.
Redundant Links and Spanning Tree Protocols. An AT-8411 TX line card with more than five
ports functioning as redundant links to other network devices could have significantly
impaired the speed of convergence for STP, RSTP, and MSTP. This issue has been resolved.
VLAN Port Entry Issue. In the process of creating a VLAN, if you entered a port number, a
comma, and a space before the next port number, the VLAN creation was rejected. This
occurred on local and Telnet management sessions. This issue has been resolved.
Default VLAN Tagged Display Issue. When deleting tagged VLAN ports, a display issue could
occur. If you created a VLAN with a PVID other than 1 and assigned the ports in the new VLAN
as tagged ports and then delete the new VLAN, the display would show the ports as tagged
when they should have been displayed as untagged. This problem has been resolved
