Simple NAT rules, on the OS7000, that have conditions whose IP address/subnet overlaps with switch
addresses will match traffic sent from these addresses, even if the traffic is bridged.
Workaround: Along with the generic NAT rule, a higher precedence non-NAT rule must be added to
match traffic from the switch addresses that overlap with the generic NAT rule.
For instance, if you wanted to remap the subnet 124.10.10/24 to 60.0.0.2, but also had a switch address of
124.10.10.5, you would have two rules:
policy condition nat source ip 124.10.10.0 mask 255.255.255.0
policy action nat destination rewrite ip 60.0.0.2
policy rule nat condition nat action nat precedence 100
policy condition exception_ip source ip 124.10.10.5
policy action accept disposition accept
policy rule exception condition exception_ip action accept precedence 200.

Destination Port and Destination Interface Type policies are not supported across Link Aggregation using
QoS Policy on the OS7000.
Workaround: There is no known workaround at this time.
PR 62076
After a write memory command and subsequent reboots on the OS7000, QoS will display all the LDAP
policies as active, even if these policies were previously deleted from the LDAP Server or if the Policy
Validity Period had expired.
Workaround: There are two workarounds:
1. From CLI, issue a policy server flush command before a write memory command.
2. If the write memory command has been issued before a reboot, edit the boot.cfg file and remove any
LDAP policies (conditions, action and rules) that are no longer valid and reboot the switch.
