ICMP Ping - Cisco Prime Collaboration Manager

[Dean O'Meara]

Hi,

We are looking to setup CPCM for one of our customers but the chances are ICMP Ping will be blocked and according to the below guide ICMP Ping is required for all devices for checking reachability.

http://docwiki.cisco.com/wiki/Required_Ports_for_Prime_Collaboration

Does anyone know if alternative methods can be used by CPCM for checking reachability?

Thanks

hi Dean,

You can work around. Set the property below to false

in this file /opt/emms/emsam/conf.emasm.properties

#

# ICMP Ping - Enable/Disable

#

com.cisco.nm.emms.discovery.icmp.ping = true

now in the Device Work Center > manage credentials > Select the profile and hit the verify button and see if the device gets the 2 green checks.

Hi Dilip,

thanks for sharing the info[+5]. Since CPA/CPCis  Linux based, how do we do this .Please elaborate.

I was reading the deployment guide which says that we can use following methods for discovering devices:

a. Ping Sweep

b. Logical Discovery

c. CDP

d. None

But I was just trying to find out where exactly we do this in Prime Assurance 9.x

Hello Aman,

you can do the following:

1. ssh -p 26 root@primecollabip-address

2. Open the file with your favorite edito. For eg: vi /opt/emms/emsam/conf.emasm.properties

3. Scroll down to the section which has the ping property. the lines looks like the below

#

# ICMP Ping - Enable/Disable

#

com.cisco.nm.emms.discovery.icmp.ping = true

4. Now set the property to false.

com.cisco.nm.emms.discovery.icmp.ping = false

5. Prime Collaboration sends out a  ping to check reachability before sending SNMP/HTTP requests. With this Prime Collaboration will send out the snmp and http requests without sending out a ping.

6. You can also check the status of the discovery at this location /opt/emms/emsam/log/Inventory/AccessLevelDiscovery.log

Hope I am clear this time

Hi

Not sure I understand your question here. can you elaborate

You need to have CDP turned on in the devices and for logical discovery 

we need to have snmp access and http access for the UC applications and snmp access to the gateway and other devices associated with the CUCM

thx

Hi digangad

This worked perfectly in version 9.5 however we have recently upgraded to version 10.5 with Service Pack 1 applied.

We have just tried to locate the file you mention above to make the change so that Ping is not needed however we can no longer find this file.

We then run a search for "conf.emasm.properties" and were unable to find this file. Do you know if the file name has changed or directory?
