I have Soundstation IP 6000s UCS 4.0.10.0568 and am trying to use Custom option code 192 to provide a list of 5 VLAN IDs.
The phone appears to come up reletively quickly if the available VLAN is the first in the list (811). However, if the valid VLAN is 2nd (VLAN) it takes about 2 minutes and 30 seconds to get an IP on that VLAN. And it seems like I have to adde 2 1/2 minutes for each VLAN after that.
I have the following VLAN settings on the phone:
VLAN Filtering = Enabled
LLDP = Disabled
CDP = Disabled
DHCP VLAN Discovery = Custom
DHCP VLAN Option = 192
My switch ports are all configured with the default VLAN 1 untagged and VoIP VLAN 8xx Tagged.
Is there any way to speed up the DHCP Release and Request process?
