Setting up UC520

[Michael Ricci]

I just recently bought a Cisco UC520, it consists of 2 parts, the CU500 series and UC520 switch module itself. The switch module has no console port, and I am trying to connect to it. I following the instructions in the CCA, which are connecting my laptop to port 1 of the UC520, and setting my network configurations to pull an IP address dynamically, but I am pulling an IP address of 169.254.0.4, when I think it is supposed to pull an IP address of 192.168.X.X, how to I fix this issue?

Hi,

Your windows machine can't get a dhcp address so it gets an APIPA address(169.254.0.4).

So you must find why DHCP is failing. Can you try renewing your DHCP lease and sniff interface(eg with wireshark).

Post pcap file here.

Regards.

Alain.

Could my config be affecting it?

no ip dhcp use vrf connected
ip dhcp excluded-address 172.16.1.1
ip dhcp excluded-address 172.16.1.31
ip dhcp excluded-address 172.16.2.1
ip dhcp excluded-address 172.16.2.31
!
ip dhcp pool Voice_Afg
   network 172.16.1.0 255.255.255.224
   default-router 172.16.1.1
   option 150 ip 172.16.1.1
!
ip dhcp pool Data_Afg
   network 172.16.2.0 255.255.255.224
   default-router 172.16.2.1

I do a show cdp nei det and it shows the APIPA IP address

Hi,

your laptop should be getting  an address from this pool:

ip dhcp pool Data_Afg

do a debug ip dhcp server event after renewing on client

You are referring to the configuration on the Cisco Unified 500 series, I am trying to connect to the Catalyst Express 520 Series though, I should be pulling an IP address from that, that config I posted has nothing to do with the UC520, my bad for posting that

Hi,

Catalyst express 520 is a L2 switch as far as I know so it can't be a dhcp server but it can receive an ip address from a dhcp server for its management.

So you connected this switch to UC500? This is UC500 which should give ip address.
