Resolved Issue in New Versions

• Switch ports did not link up with network devices after they were disabled and enabled with the management interface. This is resolved.

Resolved Issues from Previous Versions

• PoE switches displayed PoE status incorrectly on the LEDs and in the web browser management interface, or entered extraneous entries in the event log. Resolved in  v3.0.5 for the AT-GS950/10PS, AT-GS950/16PS, and AT-GS950/48PS switches.
• The following Common Vulnerabilities and Exposures (CVE) were resolved in v3.0.5 for the AT-GS950/10PS, AT-GS950/16PS, and AT-GS950/48PS switches.

• Loopback Detection did not work correctly when the unit was rebooted after detecting a loop. Resolved in v3.0.5 for the AT-GS950/10PS, AT-GS950/16PS, and AT- GS950/48PS switches.

• The switch discarded UDP packets with a fragment offset of 0 or higher and the destination port 64516 (0xFC04). Resolved in v3.0.5 for the AT-GS950/10PS, AT- GS950/16PS, and ATGS950/48PS switches.

• DHCP Snooping actions were inconsistent when all ports were designated as untrusted.
  Resolved in v3.0.5 for the AT-GS950/10PS, AT-GS950/16PS, and AT-GS950/48PS switches.

• DHCP Snooping blocked changing ports’ trusted or untrusted status. Resolved in v3.0.5 for the AT-GS950/10PS, AT-GS950/16PS, and AT-GS950/48PS switches.

• PoE switches did not block power to powered devices that required more power than defined by their PoE Classes. Switches now block power to those devices. Resolved  in v3.0.6 for the AT-GS950/10PS, AT-GS950/16PS, and AT-GS950/48PS switches.

• Switches did not update the Runtime Image value in the Switch Information window after firmware updates. Resolved in v3.0.6 for the AT-GS950/10PS switch.

Operational Notes

• The web browser interface may not refresh the Physical Interface window after you enable or disable ports. To update the window, refresh the web browser page or  move to another window and then return to the Physical Interface window.
• The switch may not update the Static Unicast Address Table after you add, delete, or modify static or LACP port trunks during periods of heavy traffic. Traffic  forwarding is not affected. (AT-GS950/48PS switch only.)
• Designating multiple ports as the source ports of the port mirror may cause the switch to drop packets on the destination port. To avoid this, designate only a few ports  at a time as source ports in the port mirror.
• Port egress traffic might exceed the egress rate limit set in storm control.
• Multiple ingress traffic streams with the same Cost of Service (CoS) priority value on a port will be assigned to the same egress queues on the egress ports, but may be transmitted at different rates. The difference between the rates depends on the ports. The smaller the physical distance between egress ports (e.g., ports 1 and 2), the smaller the rate difference. The larger the distance between ports (e.g., ports 1 and 12), the larger the difference.
• SSH is not supported.
• Combo SFP ports must remain in Automatic mode.
