CUOM 2.01 ip phone monitoring & discovery prerequisite.
Hi to all.
I want ask you some informations about CUOM prerequisite.
If I have a very large network infrastructure with a lot of switches and also not cisco devices, may I have to configure the SNMP read only Community and the CDP on ALL switches, or only on the first switch where CUOM is attached on and on the last switch where the IP PHONES are attached??
I have the following enviroment:
1]CUOM 2.01 with SP1 and all cisco patches for 2.01 release, on windows 2003 standard edition R2.
2]CCM(call manager) linux version 22.214.171.1240-3
3]The CUOM monitor and discovery correctly the CALL MANAGER (adding http credential and snmp RO community)
4]The CUOM monitor and discovery the FIRST and LAST cisco switch on which SNMP community & CDP are enabled.
5]The ip phones models are supported.
The problem is that the CUOM doesn't discovery and add to monitoring the ip PHONES that are attached to last cisco swicth.
So I don't understand HOW the CUOM discovery and add the ip PHONES.
Does the CUOM add the IP PHONE BY CALL MANAGER or BY swicthes??
May I have to enable SNMP and CDP on ALL switches/routers ?
Re: CUOM 2.01 ip phone monitoring & discovery prerequisite.
Phones are discovered by adding the CUCM into CUOM. If the phones are registered to a CUCM already being monitored by CUOM then to troubleshoot see if the phone shows up in the snmpwalk of ccmphonetable (.126.96.36.199.188.8.131.52.184.108.40.206). The only reason we ask that CDP is enabled on the switch is if you do a discovery by CDP hop count or you want the switch information to show in the phone report (switch ip, phone port, etc.). If you want the switch information to show in the phone report then you have to have CDP enabled on the switch and add the switch into CUOM.
The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
answer. Be sure to read the whole thing or e...
