The ip-port and mac-ip-port binding rules filter the IP address on a port configured if it does not match on
an OS7000 series switch. Once the MAC address is made part of the VLAN targeted by such rules, the IP
address can change to another address in the subnet or subnets carried on that VLAN.
For example, if an ip-port binding rule is created for VLAN 21 with an IP address of 21.0.0.22 and a port
of 2/3, the device has an IP address configured as 22.0.0.22. When the device is connected to 2/3 and traf-
fic is generated, such as a ping to another subnet 22 address, the port will be listed by the MAC address
table in VLAN 21. If the device, such as Windows NT or 2000, changes its address to 21.0.0.41, the
switch will continue to carry the new traffic and not be blocked as expected with this type of binding rule.
Workaround: Reboot the device or disconnect the link to restore normal binding rule behavior.

MAC-port rules does not block other MACs from using the same port on an OS7000 series switch.
Workaround: There is no known workaround at this time.
PR 68371
VPA on a mobile port does not flush out the VPAs when rules are deleted on an OS7000 series switch.
Workaround: The system relies on the VPA aging out process rather than deleting it proactively on rule
deletion. However, VPAs are deleted when the VLAN as a whole is deleted or if mobility is removed from
the port.
PR 68495
During the learning process of two flows matching two different rules on a mobile port, the second flow is
seen as learned on the VLAN of the first flows on an OS6624/6648 series switch. This is temporary
because the address ages out.
Workaround: There is no known workaround at this time.
PR 68762
Traffic is discarded or classified only in default VLANs on an OS6624/6648 series switch.
Workaround: Change the mobile port, which is having the problem, to a fixed port and then back to
mobile again. If this does not fix the problem, apply a link down and up on the port.
PR 68968
Switching to a single mode MAC router does not deallocate already allocated MACs which have been
saved in the configuration file on an OS7000/8800 switch.
Workaround: If you are switching to single mode, delete all MAC allocated commands from the
boot.cfg.
