Operating Considerations in Release 3.0.5 75
■
The MIB a3ComSysBridgePortReceiveMulticastLimit allows setting an
out-of-range value. (28995)
■
You cannot configure more than one routing interface on a
multiprotocol VLAN using SNMP. Instead, configure the routing
interface through the Administration Console.
RMON
■
You can use the
snmp rmonConfiguration
command on the
Administration Console to change the RMON statistics default from
collecting receive-only traffic to collecting transmitted and received
traffic. Doing so affects the statistics, history, alarm, and event RMON
groups. The rest of the RMON groups can only collect received traffic;
however, because these groups collect conversation information
between hosts, transmitted traffic also is included in the data for these
tables.
Ethernet
■
Gigabit Ethernet ports do not autonegotiate with a SUN Ultra 2
Gigabit Ethernet card. If traffic is sent from the SUN during
autonegotiation, then autonegotiation completes successfully.
(28448)
■
If the autonegotiation feature for a 100 Mbps Ethernet link does not
function properly, disable autonegotiation and manually set the port
speed and duplex mode (
half-duplex
or
full-duplex
). Also, on a
1000 Mbps link, autonegotiation must be enabled on both sides of
the link.
■
The noRxBuffers (frames that were discarded due to no available
buffer space) counter may increment after an AppleTalk virtual LAN
(VLAN) modify and Address Resolution Protocol (ARP) update.
■
The rxFrameRate and rxBytes statistics found in the
ethernet detail
display are incorrect. These statistics incorrectly add an extra 8 bytes to
every packet that receives a 100 Mbps port. For example, when a 64
byte frame is sent into a 100 Mbps 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.
Bridging
■
Do not set the Bridge aging time to 0 (zero). (21914)
■
Bridged IP multicast frames are not counted in the bridge statistics.
■
The bridge port address count, which is the count of the actual
number of addresses in the address table, may not match the bridge
