When I open Network Map menu, "A Network Map does not exist because, Topology Discovery has not run." message appears ans all devaces are listed as Un-Mapped Devices.
What is wrong?
I'm using Procurve 9304, 3400cl and 2824 Switces in my network.
Solved! Go to Solution.

Re: Procurve Manager problem
1. If using PCM 2.1, make sure to apply Update 6
2. Update the firmware on the switches to the latest releases
3. Try rebooting the PCM server.

Re: Procurve Manager problem
With the newer firmware on the 3400's and 2800's they do not send CDP packets so the 9300 will not have any entries in its CDP table. I suspect this may cause some issues during the topology discovery.

SolutionAlso make sure communication between the PCM server and the switch is successful by executing "test communication parameters in PCM" on the switches not being mapped.

Re: Procurve Manager problem
Try from the PCM+ server to ping the switches, it should be ok, then you can try to use the manual discovery.
Try also Hector's advice regarding the LLDP.
Good Luck !!!

Re: Procurve Manager problem
PCM makes it's maps basing on FDP/CDP/LLDP protocols.
My 3400cl and 2428 switches are not connected to each other, they are connected to 9304m switch
3400cl and 2428 use LLDP protocol and don't understand FDP protocol
9304m uses FDP and don't understand LLDP
All the switces can read CDP packets, but they cannot generate them :(
And because of this PCM cannot build a map (9304 gives nothing through FDP, and 3400&2428 gives nothing through LLDP).
Can somebody suggest a desigion of this problem?

Re: Procurve Manager problem
In PCM's second phase of the discovery process, ARP discovery is used to find any other active network devices (in ARP tables) that are not discovered via LLDP, CDP or FDP.
So if you have the 9300, 3400 and 2400 each on different subnet, and you are sure that your PCM server can reach all of them.
Why don;t you go for Manual Discovery, it will read each switch's Arp table and build your network in this Special Case with the use of the 9300 that doesn;t support LLDP.
Good Luck !!!
