OmniSwitch 6600/7000/8800—Release 5.1.6.R02 page 85
PR 73767
On an OS7000/8800 switch, when setting a permanent MAC address to filtering, traffic going to this
MAC will always be dropped regardless of the QoS rules (even if one permit rule matches this MAC).
When setting a permanent MAC address to bridging, traffic going to this MAC will always be accepted at
best effort, regardless of the QoS rules. Therefore, it becomes impossible to set any priority, stamping/
mapping or bandwidth shaping actions for traffic going to this MAC address.
Workaround: There is no known workaround at this time.
PR 74062
On an OS6624/6648 switch, it is not possible to create a L3 ACL on a source, and another on a destina-
tion, because currently the OS6600 cannot link up the source and destination.
Workaround: There is no known workaround at this time.
PR 76901
On an OS6624/6648 switch, the QoS 5.1.4.R01 configuration file is not compatible when certain rules are
used. A boot.cfg.1.err file may be generated upon bootup.
Workaround: Based on the errors generated in the boot.cfg.1.err file, the user has to edit the boot.cfg file
and remove all the unsupported features. Features that were supported in QoS 5.1.4.R01 on an OS6600
series switch, but are currently not supported are as follows: 1. TOS/DSCP to 802.1p Stamping rule not
supported. 2. 802.1p to TOS/DSCP mapping rule not supported. 3. No Interface Type support in a L3
policy condition.
PR 80707
QoS rules have no "matches" after 2 takeovers.
Workaround: The match count shown from the CLI currently reflects only newly created flows/matches.
On a takeover, if the flows aren't flushed and re-learned, the match counts will remain 0 on the secondary
until new flows are matched (or the old ones time out and are re-learned).

Layer 2 P-Stamping rules are not supported on OS6600 series switches link aggregation ports.
Workaround: There is no known workaround at this time.
PR 84386
In some setups where the same destination is used, but the source is different, a Layer 4 rule does not
affect traffic if another rule of higher precedence exists on an OS6600 series switch.
Workaround: Make the Layer 4 rule the highest precedence rule.
