■
The
rxFrameRate and rxBytes
statistics in the
ethernet detail
display are incorrect. These statistics incorrectly add an extra 8 bytes to
every packet that a 100 Mbps port receives. For example, when a 64
byte frame is sent into a 100 Mbit port, the value
72
is displayed in
the
ethernet detail
rxBytes field. Also, when 148,880 frames per
second are sent into a 100 Mbit port, the value
151,143
frames per
second is displayed in the
ethernet detail
rxFrameRate field.

For non-connected front panel ports, the Autonegotiation state
displays
failed
. This is a display issue only. This condition applies to
the 9-port 1000BASE-SX Gigabit Ethernet Layer 2 Switching Module
(Model Number 3CB9LG9MC). (26528)
Bridging
■
The following bridge commands may take a few minutes to complete
when several VLANs are configured in the system in allClosed mode:
■
bridge vlan mode
■
bridge vlan define
■
bridge vlan remove
■
bridge trunk define
To minimize this delay, configure VLANs in order of increasing VID and
remove them in order of decreasing VID.
■
The time that it takes for addresses to age out of address tables may
be up to twice as long as the bridge aging time attribute indicates.
■
Bridge port addresses in the address list display are not sorted
numerically. If you need to find a specific MAC address, use the
bridge port address find
command.
■
The txFrames statistic in the
bridge port summary
display increments
on ports with a down link state. (27962)
■
The bridge port address count, which is the count of the actual
number of addresses in the address table, may not match the bridge
port address list under certain conditions. The bridge port address list
command does not list
control addresses (MAC addresses for control
frames that go directly to the processor).
Control addresses are installed
in the address table under the following circumstances:
■
Spanning tree for the bridge is enabled.
■
TCMP is enabled on any of the defined trunk groups.
■
An IP VLAN interface is defined (there is a control address in the
address table for each port within the associated VLAN).
