802.1Q
Problem Reports
PR 37415
The OS7000 frame parser does not recognize Token Ring or FDDI SNAP frames with 802.1Q encapsula-
tion. If the parser encounters these frames, they are misclassified as flood frames.
Workaround: There is no known workaround at this time.
PR 72541
The OmniCore does not support hybrid VLANs where tagged and untagged frames are present. A port
must be tagged to add it to multiple VLANs. From that point forward, it will drop all untagged frames.
This is only a problem when connected to the OS7000 that has the default VLAN on the switch in use and
that port is connected to a tagged port on an OmniCore. The OS7000 will not be able to talk to the Omni-
Core on the default VLAN on that port.
Workaround: Make the default VLAN on a port connected to an OmniCore an unused VLAN. This will
cause all the frames coming out of the OS7000 be tagged, and it will also accept all the tagged frames
coming from the OmniCore.
PR 78486
CLI debug 802.1q <slot/port> command on an OS8800 10G port does not display hw port info for all the
internal aggregate ports.
Workaround: There is no known workaround at this time.
