Firmware: R3.50-B07 (Runtime), 2.00.003 (Prom)
Hardware: A1/A2/A3
Date: Oct. 13, 2005

New added features:
1. Multiple IP interfaces per VLAN

Problem Resolved:
1. The value of TX and RX counters under "show packet port table" is not correct.
2. When DGS-3312SR stack with DES-3226S, some of ACL policies of DGS-3312SR wont apply to
DES-3226S.
3. When DGS-3312SR F/W 3.01B25 stack with DES-3226S F/W 4.02B34, DES-3326S may jump to
exception mode.

Firmware: R3.01-B25 (Runtime), 2.00.003 (Prom)
Hardware: A3
Date: Jun. 30, 2005

Problem Resolved:
1.      DGS-3312SR will jump into exception mode, if the Access ID of ACL rule is not set by ascending order.
2.      DGS-3312SR cant support LACP across units.
3.      DGS-3312SR F/W v3.01-B14 was only able to stack with DES-3226S F/W v4.02-B26 or later, and not able to stack with all previous versions of DES-3226S.
