Re: [OSL | CCIE_Voice] UCM DHCP
So you see the request coming into the server but the phone never gets them back? Can you ping the voice vlan from the server?

Re: [OSL | CCIE_Voice] UCM DHCP
Hi Anuritha, The screenshot is useful. The 4 parameters in the bottom of the screen must be set. Once you know what they means it will make sense. For now set them to in these order, you can change them later to fit your need. 3000 28800 14400 18800 On 23/06/2013 4:33 AM, "anuritha konjety" wrote: > Whats interesting is if I do a sh cdp neigh detail on Switch A, I see one > of the phones got an IP > > Device ID: SEP001BD4C6986C > Entry address(es): > IP address: 10.10.200.129 > Platform: Cisco IP Phone 7960, Capabilities: Host Phone > Interface: FastEthernet1/0/2, Port ID (outgoing port): Port 1 > Holdtime : 138 sec > > But the phone itself doesn't seem to have an IP, nothing shows up under sh > ip int bri either. > > Got a capture from callmanager pub.

It may sound silly, but I had a similar issue on a Cisco 360 program lab this week and a reboot of the CUCM sub and pub fixed it. Nothing else we did fixed the issue.

Re: [OSL | CCIE_Voice] UCM DHCP
A few points that I think worth double check: [1] Assuming this is the configuration of the DHCP on CUCM, I think the primary router doesn't require subnet mask to be specified DHCP Server : 10.10.210.10 subnet IPV4 address: 10.10.200.0 primary start addr: 10.10.200.120 primary end addr : 10.10.200.130 primary router : 10.10.200.3/255.255.255.0 [2] In the same broadcast domain (VLAN 102), you seem to have two routing interface, one on the router and another on as SVI on the switch.Unless it serves other purpose, I think you can safely remove the SVI. interface FastEthernet0/0.102 encapsulation dot1Q 102 ip address 10.10.200.3 255.255.255.0 ip helper-address 10.10.210.10 ! interface Vlan102 ip address 10.10.200.120 255.255.255.0 ! [3] Once the SVI "interface vlan102" is removed, then the interface that actually forward your request to the CUCM DHCP should be the fa0/0.102 on the router that has already been configured with ip helper-address 10.10.210.10 (assuming that this is your CUCM IP). Then, the following trace on the switch will not be relevant anymore. 01:58:00: DHCPD: Finding a relay for client 0100.1bd4.c698.6c on interface Vlan102. 01:58:00: DHCPD: there is no pool for 10.10.200.120. Once removing SVI 102, then you should try to focus your debugging effort on the Router and not on the switch. [4] Your DHCP range seems to start with 10.10.200.120 and that could cause a collision with the SVI's IP address, even if everything else is correct. I remember that IOS-based DHCP seems to assign the last IP address in the pool, but I'm not sure how CUCM DHCP select the IP address from the pool. --Somphol On Sat, Jun 22, 2013 at 10:27 AM, anuritha konjety wrote: > Ovidiu, > > Yes, & ip helper-address is configured. > > Regards, > Anu > > > On Fri, Jun 21, 2013 at 4:32 PM, Ovidiu Popa wrote: > >> Hello Anuritha >> >> Do you by any chance have an SVI on vlan 102 ? >> If yes have you tried configuring ip helper-address on that SVI ? >> >> Regards, >> Ovidiu >> >> >> >> On Sat, Jun 22, 2013 at 12:26 AM, anuritha konjety >> wrote: >> >>> Hello, >>> >>>I am having trouble with getting phones Ip address when UCM(pub) is >>> configured as the DHCP server.

[OSL | CCIE_Voice] UCM DHCP
Hello, I am having trouble with getting phones Ip address when UCM(pub) is configured as the DHCP server. Following is partial config from the switch & the router. I have made sure - 1. Dot1q trunk on HQ-RTR interface (on the switch). Make sure that all appropriate vlans are allowed on the trunk link and that native VLAN lines up (1 is default). 2. Ensure VLANs are provisioned correctly, assigned to the right interfaces, and active (sh vlan b) 3. Double check scope config on CUCM Pub. Check each parameter. 4. Made sure helper-address is configured 5. disabled CSA service from pub 6. restarted DHCP service several times DHCP Server : 10.10.210.10 subnet IPV4 address: 10.10.200.0 primary start addr: 10.10.200.120 primary end addr : 10.10.200.130 primary router : 10.10.200.3/255.255.255.0 debug ip dhcp server events: SiteA-Switch# $ 01:58:00: DHCPD: Reload workspace interface Vlan102 tableid 0. 01:58:00: DHCPD: tableid for 10.10.200.120 on Vlan102 is 0 01:58:00: DHCPD: client's VPN is . 01:58:00: DHCPD: Finding a relay for client 0100.1bd4.c698.6c on interface Vlan102. 01:58:00: DHCPD: there is no pool for 10.10.200.120.
