Basic IP Routing

Problem Reports

PR 94621

In most cases, routed packets needing fragmentation due to a smaller IP MTU on the egress network will not be fragmented and will be forwarded as-is.

Workaround: There is no known workaround at this time.

PR 106913

On OS6800 and OS6850, exceeding 20K routes in the FIB can cause system instability, especially if they are all on the same VLAN.

Workaround: Reconfigure the switch such that the number of routes in the FIB do not exceed 20K.

PR 106931

Some objects in alaIpNetToMediaTable return wrong data type (counter, instead of integer).

Workaround: There is no known workaround at this time.

DHCP Snooping

Problem Reports

PR 100435

On an OS6850, a mobile port with incoming DHCP traffic is able to have a DHCP binding created for it but it is not shown in the Binding Port Table.

Workaround: There is no known workaround at this time.

PR 106730

After DHCP Snooping is enabled against the VLAN on OS6850, adding the q-tag port to the VLAN, the newly added q-tag port is not shown in the DHCP Snooping port list.

Workaround: Added the q-tag port to the VLAN first, then enable DHCP Snooping against the VLAN.
