Avaya P550R, P580, P880 manual Redundant Switch Controller, Remote Monitoring Rmon

■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.
