Known Issues in Previous Releases
The SecureStack C2 switch now has support for RMON Capture Packet/Filter Sampling through both the CLI and
MIBs, but with the following constraints:
RMON Capture Packet/Filter Sampling and Port Mirroring cannot be enabled on the same interface
concurrently.
The user can capture a total of 100 packets on an interface, no more and no less.
o
The captured frames will be as close to sequential as the hardware will allow.
o
Only one interface can be configured for capturing at a time.
o
Once 100 frames have been captured by the hardware the application will stop without manual
intervention.
As described in the MIB, the filter is only applied after the frame is captured, thus only a subset of the
frames captured will be available for display.
There is only one Buffer Control Entry supported.
Due to the limitations of the hardware, the Buffer Control Entry table will have limits on a few of its
elements:
o
MaxOctetsRequested can only be set to the value -1 which indicates the application will capture
as many packets as possible given its restrictions.
o
CaptureSliceSize can only be set to 1518.
o
The Full Action element can only be set to ―lock‖ since the device does not support wrapping the
capture buffer.
Due to hardware limitations, the only frame error counted is oversized frames.
The application does not support Events, therefore the following elements of the Channel Entry Table are
not supported: TurnOnEventIndex, TurnOffEventIndex, EventIndex, and EventStatus.
There is only one Channel Entry available at a time.
o
There are only three Filter Entries available, and a user can associate all three Filter Entries with
the Channel Entry.
Configured channel, filter, and buffer information will be saved across resets, but not frames within the capture
buffer.
When a user authenticates via dot1x, the initial value of dot1xAuthSessionTime for the authenticated port ranges
from 10 minutes to 17 minutes. After the initial value is incorrectly set, the counter will increment normally.
When creating an inter-switch link (ISL) between two SecureStack PoE units via RJ45 or RJ21 ports, the CLI
occasionally will report the ports as delivering minute amounts of power across the ISL or may display "Other
Fault" errors. This has been determined to be a limitation of the PoE driver, and should have no effect on function
of the port.
RMON automatically creates entries for stats using indexes associated with each port. If any of the automatically
created indexes are cleared and then associated with a new entry, the new entries will not be persistent. Upon
resetting the device, RMON will automatically create entries for each port using the initial default indexes. To
avoid this situation, always use an index of 450 or greater when creating new entries.
Users cannot set port advertise ability settings on copper MGBICs.
If port mirroring is enabled on devices which have spanning tree disabled and spanning tree bpdu-forwarding
enabled, the destination mirror port will initially display one additional BPDU packet for each member of the port
mirror.
When issuing the command "set macauthentication portreauthentication <port>", the sessions currently existing
on the port specified will be reset in addition to having the MACs re-authenticate.
The command ―show policy rule admin-profile‖ will only display phone policies.
There currently is no method to clear lacp port counters.
