RMON Alarms and Event entries
RMON Alarms and Event entries are
not
saved to nonvolatile random access
memory (NVRAM). When a reset condition or power-down sequence occurs,
the entries are not preserved. This conforms to the current RFC 1757 standard.
All RMON Alarms and Events must be reentered.
RMON Event Log table’s secondary index
The RMON Event Log table’s secondary index is not incremented when all of
the table’s entries have been used. In this case, the existing indexes are reused.
Thus, the index number cannot be used to indicate the total number of log
entries received.
RMON History Control entries
A maximum of 85 RMON History Control entries per stack unit are
supported. The entry exists on the unit containing the “ControlDataSource.”
Changing from a stack unit to a standalone switch
When you change a switch from a stack unit into a standalone switch, or vice
versa, the IP address of the switch/stack changes. As a result, all existing
management applications that use the previous IP address are lost until you
reconnect using the new IP address.
Console may display a blank screen
When you connect a console terminal to an operating switch through the
Comm Port, the console may display a blank screen. This is a normal
condition. Press [Ctrl]-C to refresh the screen or, to get beyond the Nortel
Networks logo screen, press [Ctrl]-Y.
Adding or removing stack units
When you add a new unit to the stack or remove an existing stack unit, you
will not be able to perform IP management functions for approximately 30
seconds.
During this time period, the following can occur:
-- Packets are lost when performance testing with SmartBits or any other
traffic generator.
-- IP Multicast streams stop receiving.
-- TELNET sessions time out and users lose their TELNET connection
without warning. Users must re-establish lost TELNET sessions.
