I'm having issues with my Cisco UC320W controller getting config settings over to my Cisco IP phones using a Dell N1524P Switch. Currently there is a Cisco ESW-540-24P switch that connects to both the UC320W and a Sonic Wall. With the current set up the IP phones and data traffic work as expected. I'm looking to replace the Cisco ESW-540-24P with the Dell N1524P switch.
Topology is as so:
Cisco UC320W has a dedicated internet connection for voice traffic
Sonic Wall has a dedicated internet connection for data traffic
Cisco ESW-540-24P switch sits in between the sonic wall and the Cisco UC320W
In testing, the Dell N1524P was connected to the Cisco ESW-540-24P but the IP phones were not able to pull the config settings from the UC320W
Plugging the IP phone into the Cisco ESW-540-24P did pull config from UC320W and works.
The Dell switch has ISDP on and enabled on all Ports for Cisco CDP inter-operability.
Port on Dell N1524P to Cisco ESW-540-24P and all other ports on the Dell have the below settings: "switchport mode general
switchport general allowed vlan add 100 tagged
voice vlan 100"
- Port on Cisco ESW-540-24P to Dell N1524P has the settings with: " Switchport mode Trunk Tagged 100 VLAN
Untagged 1 VLAN"
Any ideas why the phone can't get any config info from the UC320W? Also appears data traffic does not work.
I did read a requirement that port fast needs to be set to on which the Dell switch was not set that way yet. I will be back on site in a couple of days so looking for anyone who may have had experience working with both these devices or similar.
Thanks for the help
