Re: [nv-l] managing Layer 3 switches

If it is running in hybrid mode, Netview
will see it as two different devices because it has two different snmp
agents. In that case, the layer2 part should be supported as a switch by
ITSA. When it is running in native mode, it is a single layer3 switch.
Switch Analyzer 1.2.1 would disregard them altogether as being routers.
Their connections are recognized as plugged in things, the same as a server,
but their layer2 capabilities are ignored.
In ITSA 1.3, while this behavior has
not changed, there is new functionality that allows you to explicitly monitor
certain ports, regardless of whether anything is plugged into them. This
is new. A side benefit of this functionality is that you can specify ports
on layer3 switches to be monitored in this way.
It is a known requirement for ITSA to
handle the layer2 aspects of layer3 switches.
The Switch application on the Netview
web console is not related to ITSA, however. If it is grayed out, it must
be that the object in the Netview database does not meet the criteria for
that application. I'm not sure what the criteria is, but I would look to
see if it's object info includes isHUB as True (since Netview does not
have an isSwitch field). In FP2, that appl was updated to support Community
String Indexing, so it handles multiple vlans nicely. Does anybody
know what the real criteria is for the Switch application? It is not mentioned
in the web manual.

Hi all,
We want to view the layer 2 info of a L3
switch (catalyst 6500). it is discovered by Netview as a router and the
switch management menu components are disabled. I would like to know is
this supported by netview and switch analyzer and how it can be configured?
NV 7.1.4 FP1 over AIX
Switch analyzer 1.2.1
Best regards,
Alaa Farrag
