not reflected in the DHCP Snooping port table.

PR 106977
When DHCP Snooping is enabled, binding entry is not created against the new root port when STP topol-
ogy is changed.
Workaround: There is no known workaround at this time.
PR 107186
For DHCP Snooping feature, the CLI should not allow user to configure ip-source-filtering on a trusted
port. However, if the port is a member of a link aggregate, the CLI does not display an error and allows the
configuration.
Workaround: Make sure the port is not a member of a link aggregate before configuring the ip-source-
filtering.
IPv6
Problem Reports
PR 86669
On an OS6850/OS9000, IPv6 Router Advertisement decrementing timers are not supported for prefix
valid lifetimes or prefix preferred lifetimes.
Workaround: Use IPv6 Router Advertisement fixed timers.
PR 91228
An OS6850 does not detect IPv6 port scanning or other IPv6 denial of service attacks.
Workaround: There is no known workaround at this time.
PR 94546
An OS9000 does not make use of the MTU interface configured via the IPv6 interface command and only
supports the port MTU. Therefore, even if the configured IPv6 interface MTU is smaller, packets will still
be forwarded instead of being dropped and “a packet too big” message returned to the sender. This can
cause problems with path MTU discovery.
Workaround: There is no known workaround at this time.
