■
If a router port for intelligent multicasting is mirrored with a
piggyback port, the piggyback port is listed instead of the
router port.
Redundant Switch Controller
The following problem has no workaround:
■
Do not enable redundancy unless you have a redundant
switch controller.
■
On a P880 with an 80-series supervisor module, the
redundant switch controller may not take over when the
active switch controller fails.
Remote Monitoring (RMON)
The following problems have no workaround:
■
30 minute RMON statistics always show utilization as 0
(Zero) on a heavily used Gigabit Ethernet port.
■
Statistics for unicast frames do not work when using
multilayer (ISL) tagging.
Simple Network-Management Protocol (SNMP)
The following problems have no workaround:
■
Cold start traps cannot be transmitted out of inband
interfaces after you enable Spanning Tree.
■
ipAddrTable does not display inactive interfaces (VLANs). An
inactive interface occurs when there are no active ports on a
VLAN.
Problem:
■
If you use the CLI to perform either of the following
commands, the supervisor module stops responding and
resets:
—
snmp walk aarpNetAddress
—
snmp walk cjnAtEchoSend
Workaround:
Use SNMP from a management station to access these MIB items.
