AT-S60 Version 2.0.0 NE Management Software Release Notes
PN 613-50544-00 Rev B 3 Allied Telesyn, Inc.
Operational Notes
The following operational limitations are present in Version 2.0.0 NE of the AT-S60
management software.
Upgrading from software version 1.1.4. After upgrading your system from Version 1.1.4 to
Version 2.0.0 NE, the switch must be reset to factory defaults.
Hot Swapping Limitation. Before you install or remove a line card, make sure you remove all
cable connections. When installing a card, you can connect a cable after the WAIT/REMOVE
LED on the AT-8401 management card turns steady green. Hot swapping a card that has a link
may cause the switch to become unstable and requires a reboot. Refer to AT-8400 Series
Switch Reference Guide for detailed instructions on installing and removing line cards.
Multi mode hot swap issue of uplink card. When a card configured with the uplink port is
removed or reinstalled, flooding will occur until the switch is rebooted.
Operator Login. Logging in as Operator does not allow you to change any switch parameters.
However, by using the Save Configuration Changes selection, an operator can save changes
that were made to the parameters of a switch by a Manager.
Multiple Spanning Tree (MSTP). Due to different vendor implementations of the new IEEE
802.1s standard, compatibility issues concerning MSTP instances between the AT-8400 Series
switch and switches from other vendors may exist. This can result in compatibility issues
between different MSTP implementations. For this release, MSTP is compatible only with other
AT-8400 Series switches.
FAN LED. The fan LED does not change to amber if the fan unit is removed. If the fan has been
removed and the fan status is viewed from the management, then the fan LED will turn amber.
AT-8413 Line Card. Only Hardware Version Rev C is supported. On the PC board of the
AT-8413, look for the PC Assembly Number “845-06414-00 Rev C”, located near the front panel.
DELETE MSTP MSTIID Command. This command is nonfunctional. To delete MSTI IDs, use
the menu or web interface.
SET STP PORT Command. You could not return a port's STP parameter settings to the default
values with this command if STP is disabled.
IGMP Multimode. When IGMP is enabled in Multimode Intermediate topology, and a host
that is joined to a group and is receiving multicast sends a leave, though the switch displays
that the host has left, the host continues to receive multicast traffic until the aging timer
expires.
Switch Timers. All systems effective timeout is in the range [0.6x - 1.2x] of the user-configured
timeout value.
Static Multicast MACs. Multicast Ingress ports must be added to the static multicast address
in order for the other ports added to the static address to receive multicast data.
